     MODE FOR DISCLOSURE 
     Hereinafter, first, a cuttable knitted fabric according to one embodiment of the present disclosure will be described. 
       FIG.  1    is a photograph of an upper surface of a cuttable knitted fabric according to one embodiment of the present disclosure.  FIG.  2    is a photograph of a lower surface of the knitted fabric of  FIG.  1   .  FIG.  3    is a vertical cross-sectional view of the cuttable knitted fabric according to one embodiment of the present disclosure.  FIG.  4    is a photograph of an end of the knitted fabric of  FIG.  1    cut along an “A” line. 
     Referring to  FIGS.  1  to  4   , a cuttable knitted fabric  100  according to one embodiment of the present disclosure may include a knitted web  110  and a reinforcing portion  120 . 
     The cuttable knitted fabric  100  may be formed of a fabric that can be cut by coupling an upper surface or a lower surface of the knitted web  110  and the reinforcing portion  120  inside the knitted web  110 . In the cuttable knitted fabric  100 , the reinforcing portion  120  is generally coupled to the knitted web  110  having a substantially plate shape, and thus, strength of the knitted fabric  100  can be higher than that of the knitted web  110 . 
       FIG.  5    is a photograph illustrating that curl-up occurs in a general knitted fabric. 
     Referring to  FIG.  5   , a general knitted fabric has a problem in that a curl-up phenomenon occurs in which an edge portion is curled due to unique characteristics of the knitted web. In addition, in the case of the general knitted fabric having a yarn break in any one portion, the knitted web may be unraveled as the yarn is unraveled. For this reason, a general knitted fabric cannot be cut, unlike a textile, and there is a limitation in producing products of various designs. 
     As illustrated in  FIGS.  3  and  4   , in the cuttable knitted fabric  100  of the present disclosure, the reinforcing portion  120  supports the knitted web  110  as a whole to prevent curl-up from occurring. In addition, since the cuttable knitted fabric  100  is fixed to the knitted web  110  while the reinforcing portion  120  is coupled to the knitted web  110 , the yarn is not unraveled even when the yarn of the knitted web  110  is cut during the cutting process. In addition, since the cuttable knitted fabric  100  has the knitted web  110  as a basic skeleton and reinforcing fibers are coupled, the knitted fabric  100  has good elasticity and flexibility and does not wrinkle. In addition, the cuttable knitted fabric  100  may have good heat retention and breathability, and may have waterproof properties. 
     The knitted web  110  may be formed by woven in a substantially plate shape by a single yarn. The yarn may be formed to include mohair, cotton yarn, or nylon. In addition, the yarn may be formed by mixing at least two types of mohair, cotton, and nylon. The knitted web  110  may be formed to include a through hole in which the yarns are spaced apart from each other and formed between the yarns. The knitted web  110  may be formed of yarns of various thicknesses or diameters. The knitted web  110  may be formed in a polygonal plate shape, such as a disk shape, a square plate shape, or a hexagonal plate shape. The knitted web  110  may be formed of a general knitted fabric. 
     Meanwhile, the cuttable knitted fabric  100  may include a plurality of knitted fabrics  110  woven by a single yarn. In this case, the knitted web  110  may be arranged so that side surfaces of the knitted web are in contact with each other or are spaced apart from each other in the knitted fabric  100 . In this case, the plurality of knitted fabrics  110  may be fixed while being coupled to one reinforcing portion  120 . 
     The reinforcing portion  120  may include an upper reinforcing layer  121 , a lower reinforcing layer  122 , an inner reinforcing layer  123 , and an edge layer  124 . The reinforcing portion  120  may be coupled to the knitted web  110  in the entire region of the knitted web  110 . The upper reinforcing layer  121 , the lower reinforcing layer  122 , the lower reinforcing layer  122 , and the edge layer  124  are coupled to each other. The upper reinforcing layer  121 , the lower reinforcing layer  122 , the lower reinforcing layer  122 , and the edge layer  124  may be integrally formed. The upper reinforcing layer  121  and the lower reinforcing layer  122  may be formed to have the same thickness or different thicknesses. 
     The reinforcing portion  120  may be formed while reinforcing fibers positioned above and below the knitted web  110  are coupled to the knitted web  110 . The reinforcing fiber may be a material having its own entanglement, such as fine fibers thinner than a yarn, a thread, or a fiber. 
     As an example, the reinforcing fiber may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or nylon cotton. The reinforcing fibers may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, and nylon cotton. 
     The reinforcing fibers of the reinforcing portion  120  have a property of being tangled with each other, and may be introduced into the yarn of the knitted web  110  and coupled to the yarn while being tangled. The reinforcing fibers of the reinforcing portion  120  may be coupled to the yarns of the knitted web  110  through a needling process. The reinforcing fibers of the reinforcing portion  120  may fix the yarn of the tissue of the knitted web  110  while filling the inside or the tissue of the knitted web  110 . Since the reinforcing fiber is thinner than the yarn, the reinforcing fiber may be easily introduced into the yarn. The reinforcing fibers may be formed into the knitted fabric  100  that can be cut by changing the physical properties of the knitted web  110  while being coupled to the knitted web  110 . 
     The reinforcing fibers of the reinforcing portion  120  may prevent the knitted web  110  from being unraveled when the knitted web  110  is cut. The reinforcing portion  120  may reduce the loosening property of the knitted web  110 . In addition, while the reinforcing fibers of the reinforcing portion  120  are coupled to the knitted web  110 , the cuttable knitted fabric  100  may maintain a constant shape. That is, the reinforcing fibers may be maintained in a layer shape on the upper and lower surfaces of the knitted web  110  while being coupled to the yarn of the knitted web  110 . 
     Meanwhile, the reinforcing portion  120  may be formed by mixing reinforcing fibers with an adhesive such as glue and needling the reinforcing fibers to be coupled to the knitted web  110 . When the adhesive is used, a bonding force between the reinforcing portion  120  and the knitted web  110  may be further increased. 
     The upper reinforcing layer  121  may be formed by layering reinforcing fibers on the upper surface of the knitted web  110 . The upper reinforcing layer  121  may be formed to have a predetermined thickness. The upper reinforcing layer  121  may be formed to entirely cover the upper surface of the knitted web  110 . The upper reinforcing layer  121  may be coupled to the yarn while some of the reinforcing fibers are introduced into the yarn. The upper reinforcing layer  121  may be formed in a region including the upper portion of the yarn and the upper portion of the through hole. The upper reinforcing layer  121  may be formed to have different thicknesses in the region of the yarn, that is, in the region in contact with the yarn and the upper region of the through hole. The upper reinforcing layer  121  may be formed such that at least a portion of the yarn is exposed. The upper reinforcing layer  121  may be formed to have an appropriate thickness according to an amount of reinforcing fiber positioned on the upper portion of the knitted web  110  during the needling process. The thickness of the upper reinforcing layer  121  may be adjusted by adjusting the amount of reinforcing fiber used. 
     The lower reinforcing layer  122  may be formed by layering reinforcing fibers on the lower surface of the knitted web  110 . The lower reinforcing layer  122  may be formed to have a predetermined thickness. The lower reinforcing layer  122  may be formed to entirely cover the lower surface of the knitted web  110 . The lower reinforcing layer  122  may be coupled to the yarn while a portion of the reinforcing fibers are introduced into the yarn. The lower reinforcing layer  122  may be formed in a region including a lower portion of the yarn and a lower portion of the through hole. The upper reinforcing layer  121  may be formed to have different thicknesses in the region of the yarn, that is, in the region in contact with the yarn and the upper region of the through hole. The lower reinforcing layer  122  may be formed such that at least a portion of the yarn is exposed. The lower reinforcing layer  122  may be formed to have an appropriate thickness according to the amount of reinforcing fiber positioned below the knitted web  110  during the needling process. 
     The lower reinforcing layer  122  may be formed by filling the inner side of the through hole of the knitted web  110  with reinforcing fibers. In addition, the lower reinforcing layer  122  may be formed so that some of the reinforcing fibers introduced into the yarn of the knitted web  110 . That is, the lower reinforcing layer  122  may be positioned so that the reinforcing fibers penetrate into the yarn. The lower reinforcing layer  122  is integrally formed with the upper reinforcing layer  121  and the lower reinforcing layer  122  and is coupled thereto. Accordingly, the lower reinforcing layer  122  allows the reinforcing portion  120  to be coupled to the knitted web  110 . 
     The inner reinforcing layer  123  may be formed by filling the through hole with reinforcing fibers. The inner reinforcing layer  123  may be integrally formed with the upper reinforcing layer  121  and the lower reinforcing layer  122  to fix the upper reinforcing layer  121  and the lower reinforcing layer  122 . 
     The edge layer  124  may be formed such that the reinforcing fibers form a band shape on the edge of the knitted web  110 . The edge layer  124  may be formed in a band shape while the reinforcing fibers are stretched. The edge layer  124  may be formed to have a predetermined thickness. The edge layer  124  may be formed without the knitted web  110  therein. An outer end of the edge layer  124  may be formed in an irregular shape. For example, a distance of the edge layer  124  from the knitted web to the outer end may be irregular. The edge layer  124  may be formed to surround the periphery of the knitted web  110 . The edge layer  124  may support the periphery of the knitted web  110  while being integrally formed with the upper reinforcing layer  121  and the lower reinforcing layer  122 . Accordingly, the edge layer  124  may prevent the yarn of the knitted web  110  from being unraveled during use of the knitted fabric  100 . In addition, the edge layer  124  supports the edge of the knitted web  110  so that the knitted web is not unraveled when the yarn of the knitted web  110  is cut. 
       FIG.  6    is a photograph illustrating clothes and accessories made of the knitted fabric of the present disclosure. 
     Referring to  FIG.  6   , in the cuttable knitted fabric  100  of the present disclosure, the knitted web  110  and the reinforcing portion  120  are entangled with each other as a whole, so that curl-up and loosening of the yarn do not occur after being cut. Through this, the cuttable knitted fabric  100  can be cut into various sizes and various shapes, and thus, the knitted fabric can be used as a material for various products. The cuttable knitted fabric  100  may be used in the production of sweaters, clothing such as coats, handbags, and accessories such as bags. 
     Hereinafter, a method for manufacturing a cuttable knitted fabric according to one embodiment of the present disclosure will be described. 
       FIG.  7    is a process diagram of the method for manufacturing a cuttable knitted fabric according to one embodiment of the present disclosure. 
     Referring to  FIGS.  1  and  7   , the method for manufacturing a cuttable knitted fabric includes a step S 10  of providing knitted web  110 , a step S 20  of disposing reinforcing fiber, and a step S 30  of coupling the knitted web  110  and the reinforcing fiber. The method for manufacturing a knitted fabric may further include a step S 40  of post-treatment applying moisture and heat to the needle fabric. 
     The step S 10  of providing the knitted web  110  is a step of preparing the knitted web  110 . The knitted web  110  may have an appropriate size and shape according to the required fabric. The knitted web  110  may be formed in a plate shape. The knitted web  110  may be formed by weaving a single yarn. 
     The step S 20  of disposing the reinforcing fibers is a step of disposing the reinforcing fibers on the upper and lower surfaces of the knitted web  110 . As the reinforcing fibers, a member having entanglement such as a woolen material or cotton may be used. Preferably, the reinforcing fibers may be sequentially disposed on the upper and lower surfaces of the knitted web  110 . For example, the reinforcing fibers may be first disposed on the upper surface of the knitted web  110 , and the reinforcing fibers may be disposed on the lower surface of the knitted web  110  in an inverted state. Alternatively, the reinforcing fiber may be first disposed on a separate plate, and after the knitted web  110  is disposed on the reinforcing fiber, the reinforcing fiber may be disposed on the upper surface of the knitted web  110  again. The reinforcing fibers may be disposed on the edge of the knitted web  110  in addition to the upper and lower surfaces. The reinforcing fibers may be stacked on the knitted web  110  as a whole. The reinforcing fibers may be stacked in at least one bundle according to the total area of the knitted web. In addition, the reinforcing fibers may be entirely stacked on the knitted web  110  in a plurality of small bundles. A bundle of a plurality of reinforcing fibers disposed on the upper surface of the knitted web  110  may be disposed to be alternately disposed with a bundle of reinforcing fibers disposed on a lower surface of the knitted web  110 . 
     The step S 30  of coupling the knitted web  110  and the reinforcing fiber is a step of forming a needle fabric by coupling the reinforcing fiber to the knitted web  110 . The step of coupling the knitted web  110  with the reinforcing fiber may be a needling process. The reinforcing fibers disposed on the upper and lower surfaces of the knitted web  110  may be coupled to the knitted web  110  through the needling process. In this case, the needling process may be performed while supplying a separate adhesive to the reinforcing fibers and the knitted web  110 . The adhesive may increase bonding strength between the reinforcing fibers and the knitted web  110 . The needling process may be performed while repeatedly passing the needle through the knitted web  110  on which the reinforcing fibers are disposed. The needle may be a felt needle. The reinforcing fibers need to be uniformly coupled to the knitted web  110 . In order for the needle fabric to be cuttable, it is necessary that the needling process be performed with a consistent force and a consistent amount. The needling process may be preferably performed using a needling device. Meanwhile, the needling process may be performed as a general needling process. The needling process may be repeated in a state where the upper surface of the knitted web  110  faces upward, and in addition, the process proceeds again with the lower surface of the knitted web  110  facing upward. Through the reinforcing fiber coupling step, the knitted fabric may be formed with an upper reinforcing layer, a lower reinforcing layer, and an inner reinforcing layer on the knitted web  110 . In addition, the knitted fabric may be formed with an edge layer  124  surrounding the periphery of the knitted web  110 . 
     The post-treatment step S 40  is a step of performing by supplying moisture to the needle fabric and applying a predetermined temperature to perform drying and curing. The post-treatment step may be performed by an appropriate method depending on the use of the knitted fabric. 
     As an example, the cuttable knitted fabric  100  may be treated by immersion in water. In this case, hot water and cold water may be used as the water. Here, the hot water is water having a temperature higher than room temperature, and may be water of 40 to 80° C. The cold water is water having a temperature lower than room temperature, and may be water of 10 to 20° C. The cuttable knitted fabric  100  may be treated by alternately immersing the knitted fabric  100  in hot and cold water. The cuttable knitted fabric  100  may be shrunk in advance through the post-treatment. Accordingly, the cuttable knitted fabric  100  may be reduced in shrinkage during use. 
     In addition, in the post-treatment step, the cuttable knitted fabric  100  may be treated by spraying water or spraying high-temperature and high-pressure steam. 
     In addition, the cuttable knitted fabric  100  may be immersed in a soap solution and rubbed against each other. The soap solution may be maintained at a temperature of 40 to 80° C. The cuttable knitted fabric  100  is rubbed against each other in a state of being immersed in the soap solution, the reinforcing fibers are tangled, and thus, the bonding force between the reinforcing fibers and the knitted web  110  may be increased. In addition, the cuttable knitted fabric  100  may be immersed in soap solution and contracted while rubbing and thickened. The cuttable knitted fabric  100  may have a dense texture and a softer feel. 
       FIG.  8    is a photograph illustrating a cuttable knitted fabric  200  according to one embodiment of the present disclosure.  FIG.  9    is a photograph illustrating an example of a cross-section of the cuttable knitted fabric  200  that is cut along a line “B” illustrated in  FIG.  8   . 
     Referring  FIGS.  8  and  9   , the cuttable knitted fabric  200  according to one embodiment of the present disclosure may include a knitted web  210 , a first reinforcing portion  220 , and a second reinforcing portion  230 . In the cuttable knitted fabric  200 , the first reinforcing portion  220  and the second reinforcing portion  230  may be coupled to one of a front surface (or upper surface) and a back surface (or lower surface) of the knitted web  210 . 
     As an example, in the cuttable knitted fabric  200 , the first reinforcing portion  220  and the second reinforcing portion  230  may be coupled to the back surface (or lower surface) of the knitted web  210  to increase tensile strength. The first reinforcing portion  220  and the second reinforcing portion  230  may be formed of different materials and may have different tensile strengths. As an example, the first reinforcing portion  220  may have a high tensile strength in an X-axis direction, and the second reinforcing portion  230  may have a high tensile strength in a Y-axis direction. As an example, the first reinforcing portion  220  may have a high tensile strength in the Y-axis direction, and the second reinforcing portion  230  may have a high tensile strength in the X-axis direction. 
       FIG.  10 A  is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion and the second reinforcing portion according to one embodiment of the present disclosure. 
     Referring to  FIGS.  8 ,  9 , and  10 A , the first reinforcing portion  220  may be disposed to correspond to a partial region of the back surface (or lower surface) of the knitted web  210 . As an example, the first reinforcing portion  220  may be disposed to correspond to a central portion of the back surface (or lower surface) of the knitted web  210 . 
     The second reinforcing portion  230  may be disposed to correspond to a partial region of the back surface (or lower surface) of the knitted web  210 . As an example, the second reinforcing portion  230  may be disposed to correspond to an edge of the back surface (or lower surface) of the knitted web  210 . The second reinforcing portion  230  may be disposed to surround the periphery of the first reinforcing portion  220 . 
     The first reinforcing portion  220  and the second reinforcing portion  230  may be formed of different materials. The first reinforcing portion  220  disposed to correspond to the central portion of the knitted web  210  may be formed of a fiber material having a cushioning feeling and soft characteristics. The second reinforcing portion  230  disposed to correspond to the edge of the knitted web  210  may be formed of a fibrous material having high rigidity to prevent the knitted web  210  from being unraveled. 
     In  FIG.  10 A , the first reinforcing portion  220  and the second reinforcing portion  230  are illustrated as having a circular shape. However, the present disclosure is not limited thereto, and the shapes of the first reinforcing portion  220  and the second reinforcing portion  230  may be variously changed according to the shape of the cuttable knitted fabric  200  (for example, a square, a rhombus, a trapezoid, or the like). 
     Again, referring to  FIG.  9   , the first reinforcing portion  220  and the second reinforcing portion  230  may support the knitted web  210  as a whole to prevent curl-up from occurring. In addition, in the cuttable knitted fabric  200 , the first reinforcing portion  220  and the second reinforcing portion  230  are coupled to the knitted web  210 , and thus, the yarn of the knitted web  210  and the reinforcing fibers constituting the first reinforcing portion  220  and the second reinforcing portion  230  are entangled with each other. Since the first reinforcing portion  220  and the reinforcing portion  230  fix the knitted web  210 , the yarn is not unraveled even when the yarn of the knitted web  210  is cut during the cutting process. In addition, since the cuttable knitted fabric  200  is formed by having the knitted web  210  as a basic skeleton and coupling the first reinforcing portion  220  and the second reinforcing portion  230  using reinforcing fibers as a material, the knitted fabric  200  has good elasticity and flexibility and does not wrinkle. The knitted web  210  may be formed by being woven in a substantially plate shape using a single yarn. 
       FIG.  10 B  is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion and the second reinforcing portion according to one embodiment of the present disclosure. 
     Referring to  FIG.  10 B , shapes of a first reinforcing portion  220 - 1  and a second reinforcing portion  230 - 1  may be variously changed according to the shape of the cuttable knitted fabric  200 - 1 . As an example, the knitted web  210 - 1  may be formed in a rectangular shape (for example, a square shape, a rectangular rigid shape), and the first reinforcing portion  220 - 1  and the second reinforcing portion  230 - 1  may be formed in an elliptical shape. That is, the knitted web  210 - 1 , the first reinforcing portion  220 - 1 , and the second reinforcing portion  230 - 1  may be formed in different shapes. 
     The first reinforcing portion  220 - 1  may be disposed to correspond to a central portion of a back surface (or lower surface) of the knitted web  210 - 1 . The second reinforcing portion  220 - 2  may be disposed to correspond to an edge of the back surface (or lower surface) of the knitted fabric  21 - 1 . The second reinforcing portion  230 - 1  may be disposed to surround the periphery of the first reinforcing portion  220 - 1 . 
     The first reinforcing portion  220 - 1  and the second reinforcing portion  230 - 1  may be formed of different materials. The first reinforcing portion  220 - 1  disposed to correspond to the central portion of the knitted web  210 - 1  may be formed of a fiber material having a cushioning feeling and soft characteristics. The second reinforcing portion  230 - 1  disposed to correspond to the edge of the knitted web  210 - 1  may be formed of a fiber material having a strong characteristic so that the knit of the knitted web  210 - 1  is not unraveled. 
       FIG.  10 C  is a view illustrating the knitted web of the cuttable knitted fabric and an arrangement form of the first reinforcing portion, the second reinforcing portion, and a third reinforcing portion according to one embodiment of the present disclosure. 
     The first reinforcing portion  220 - 2 , a second reinforcing portion  230 - 2 , and a third reinforcing portion  240 - 2  having different shapes may be disposed on a back surface (or lower surface) of the knitted web  210 - 2 . As an example, the first reinforcing portion  220 - 2  may be formed in a circular shape. The second reinforcing portion  230 - 2  may be formed in a rhombus shape. The third reinforcing portion  240 - 2  may be formed in an elliptical shape. 
     The first reinforcing portion  220 - 2  may be disposed to correspond to the central portion of the knitted web  210 - 2 . The second reinforcing portion  230 - 2  may be disposed to surround the periphery of the first reinforcing portion  220 - 2 . The third reinforcing portion  240 - 2  may be disposed around the second reinforcing portion  230 - 2 . 
     The first reinforcing portion  220 - 2 , the second reinforcing portion  230 - 2 , and the third reinforcing portion  240 - 2  may be formed of different materials. The first reinforcing portion  220 - 2  disposed to correspond to the central portion of the knitted web  210 - 2  may be formed of a fiber material having cushioning and soft properties. The second reinforcing portion  230 - 2  disposed to correspond to the edge of the knitted web  210 - 2  may be formed of a fiber material having high rigidity to prevent the knit of the knitted web  210 - 2  from being unraveled. The third reinforcing portion  240 - 2  disposed around the second reinforcing portion  230 - 2  may be formed of a fibrous material having high rigidity to prevent the knit of the knitted web  210 - 2  from being unraveled. Here, directions of tensile strengths of the second reinforcing portion  230 - 2  and the third reinforcing portion  240 - 2  are formed to be different from each other. Accordingly, even when the knitted web  210 - 2  extends in the X-axis direction, the Y-axis direction, and the diagonal direction, it is possible to maintain the shape of the knitted web  210 - 2  and prevent the knit of the knitted web  210 - 2  from being unraveled. 
     The yarn of the knitted web  210 ,  210 - 1 , or  210 - 2  may include wool, lana merino wool, nylon, polyamide, or acrylic. 
     The present disclosure is not limited thereto, and the yarn of the knitted web  210 ,  210 - 1 , or  210 - 2  may include a mixed blend obtained by mixing at least two of wool, lana merino wool, nylon, polyamide, and acrylic. 
     The present disclosure is not limited thereto, and the yarn of the knitted web  210 ,  210 - 1 , or  210 - 2  may include a mixed blend obtained by mixing wool of 35%, polyamide of 25%, and acrylic of 40%. 
     The present disclosure is not limited thereto, and a ratio (%) of materials constituting the yarn of the knitted web  210 ,  210 - 1 , or  210 - 2  may be changed according to clothing and accessories made of the cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2 . 
     The knitted web  210 ,  210 - 1 , or  210 - 2  may be produced to have a weaving thickness of 5 mm to 12 mm using a hand knitting machine. A length of the knitted web  210 ,  210 - 1 , or  210 - 2  in the first direction may be formed to be 50 cm to 150 cm, and a length in the second direction may be formed to be 100 cm to 250 cm. The present disclosure is not limited thereto, and length of the knitted web  210 ,  210 - 1 , or  210 - 2  in the first direction and the second direction are not limited. As the size is reduced by steam and heat treatment during the manufacturing process of the cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2 , in consideration of the reduced length, the length of the knitted fabric  210 ,  210 - 1 , or  210 - 2  in the first direction and the second direction may be set. Here, according to the number of needling for mixing the knitted web  210 ,  210 - 1 , or  210 - 2  and the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2 , the number of heating and the heating temperature for the knitted web  210 ,  210 - 1 , or  210 - 2  and reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2 , and the number of steaming and the steam temperature applied to the knitted web  210 ,  210 - 1 , or  210 - 2  and the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2 , the ratio % of reduced lengths in the first direction and the second direction may be changed. 
     As an example, during the manufacturing process of the cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2 , the lengths in the first direction and the second direction may be reduced by approximately 20%. In this case, in order to form the cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2  having a length of 100 cm in the first direction and 150 cm in the second direction, the knitted web  210 ,  210 - 1 , or  210 - 2  and the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  may have a length of 120 cm in the first direction and a length of 180 cm in the second direction. By performing the manufacturing process using the knitted web  210 ,  210 - 1 , or  210 - 2  and the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  having the length of 120 cm in the first direction and 180 cm in the second direction, it is possible to form the cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2  having the length of 100 cm in the first direction and the length of 150 cm in the second direction. 
     The cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2  may include the plurality of knitted webs  210 ,  210 - 1 , or  210 - 2  woven by one yarn. In this case, the knitted web  210 ,  210 - 1 , or  210 - 2  may be arranged so that side surfaces of knitted web are in contact with each other or are spaced apart from each other in the cuttable the knitted fabric  200 ,  200 - 1 , or  200 - 2 . In this case, the plurality of knitted webs  210 ,  210 - 1 , or  210 - 2  may be fixed to be coupled to one of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2  and  240 - 2 . 
     The reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  may be formed so that the reinforcing fibers positioned below the knitted web  210 ,  210 - 1 , or  210 - 2  are coupled to the knitted web  210 ,  210 - 1 , or  210 - 2 . The reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the reinforcing fibers may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the reinforcing fibers may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     The reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  have a property of being entangled with each other, and the reinforcing fibers are introduced into the yarn of the knitted web  210 ,  210 - 1 , or  210 - 2  and entangled, and thus, may be coupled to the yarns of the knitted web  210 ,  210 - 1 , or  210 - 2 . The reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  may fix the yarns of the tissues of the knitted web  210 ,  210 - 1 , or  210 - 2  while filling the inside or the tissues of the knitted web  210 ,  210 - 1 , or  210 - 2 . Since the reinforcing fibers are thinner than the yarns of the knitted fabrics  210 ,  210 - 1 , or  210 - 2 , the reinforcing fibers may be easily introduced into the yarns. The reinforcing fiber may be coupled to the knitted web  210 ,  210 - 1 , or  210 - 2  so that the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  are formed, and the knitted web  210 ,  210 - 1 , or  210 - 2  may be coupled to the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  so that a cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2  is formed. 
     The reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  can prevent the knit of the knitted web  210 ,  210 - 1 , or  210 - 2  from being unraveled when the knitted web  210 ,  210 - 1 , or  210 - 2  is cut. The reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 ,  240 - 2  may reduce the unraveling of the knitted web  210 ,  210 - 1 , or  210 - 2 . In addition, the reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  are coupled to knitted web  210 ,  210 - 1 , or  210 - 2 , and thus, the knitted fabric  200 ,  200 - 1 , or  200 - 2  can maintain a constant shape. 
     Meanwhile, an adhesive such as a paste may be fixed with the reinforcing fibers of the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 , and  240 - 2  and needled, and thus, the reinforcing fibers can be coupled to the knitted web  210 ,  210 - 1 , or  210 - 2 . When the adhesive is used, it is possible to further increase the bonding force between the reinforcing portions  220 ,  220 - 1 ,  220 - 2 ,  230 ,  230 - 1 ,  230 - 2 ,  240 - 2  and the knitted web  210 ,  210 - 1 , or  210 - 2 . 
     The cuttable knitted fabric  200 ,  200 - 1 , or  200 - 2  of the present disclosure can be cut into various sizes and shapes, and thus, the knitted fabric can be used as a material for various products. As illustrated in  FIG.  6   , the cuttable knitted fabrics  200 ,  200 - 1 , or  200 - 2  may be used in the manufacture of clothing such as a sweater or a coat, a handbag, and accessories such as bags. 
       FIG.  11    is a process diagram for a method for manufacturing the cuttable knitted fabric  200  illustrated in  FIG.  9   .  FIG.  15    is a view illustrating a hand knitting machine for forming the knitted fabric.  FIG.  16    is a view illustrating a needle punching machine for entangling the knitted web and the reinforcing material.  FIG.  17    is a view illustrating a heat treatment machine for applying heat to a knitted web and a reinforcing material, and for spraying steam. 
     Referring  FIGS.  9  and  11   , the method for manufacturing the cuttable knitted fabric  200  may include a step S 110  of providing the knitted web, a step S 120  of disposing the first reinforcing fiber, a step S 130  of disposing the second reinforcing fiber, a step S 140  of entangling the knitted web  210 , the first reinforcing fiber, and the second reinforcing fiber, and a post-treatment step S 150 . 
     The step S 110  of providing the knitted web is a step of preparing the knitted web  210 . The knitted web  210  may have an appropriate size and shape according to the required fabric. The knitted web  210  may be formed in a plate shape. The knitted web  210  may be formed of a single yarn by using the hand knitting machine  10  illustrated in  FIG.  15   . 
     The knitted web  210  may be produced to have a weaving thickness of 5 mm to 12 mm using the hand knitting machine  10 . A length of the knitted web  210  in the first direction may be formed to be 50 cm to 150 cm, and a length in the second direction may be formed to be 100 cm to 250 cm. The present disclosure is not limited thereto, and the length of the knitted web  210  in the first direction and the second direction is not limited. As the size is reduced by steam and heat treatment during the manufacturing process of the cuttable knitted fabric  200 , in consideration of the reduced length, the length of the knitted web  210  in the first direction and the second direction may be set. 
     Subsequently, the step S 120  of disposing the first reinforcing fiber is a step of disposing the first reinforcing fibers at regular intervals on the lower surface of the knitted web  210 . The first reinforcing fibers may be disposed to correspond to the central portion of the lower surface of the knitted web  210 . The first reinforcing portion  220  may be formed through the first reinforcing fibers. 
     The first reinforcing fibers of the first reinforcing portion  220  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the first reinforcing fibers of the first reinforcing portion  220  may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the first reinforcing fibers of the first reinforcing portion  220  may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% wool (woolen material, lamb&#39;s wool, merino wool, pima wool). 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% cotton. 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 40% to 60% poly (for example, nylon) cotton, 20% to 30% wool (woolen material, lamb&#39;s wool, merino wool, pima wool), and at 20% to 30% cotton. 
     Subsequently, the step S 130  of disposing the second reinforcing fiber is a step of disposing the second reinforcing fibers on the edge of the lower surface of the knitted web  210 . The second reinforcing fiber may be disposed to surround the periphery of the first reinforcing portion  220 . The second reinforcing portion  230  may be formed through the second reinforcing fibers. 
     The second reinforcing fibers of the second reinforcing portion  230  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the first reinforcing fibers of the second reinforcing portion  230  fibers may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the first reinforcing fibers of the second reinforcing portion  230  may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% wool (woolen material, lamb&#39;s wool, merino wool, pima wool). 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the second reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton at and 30% to 50% cotton. 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the second reinforcing fibers obtained by mixing 40% to 60% poly (for example, nylon) cotton at, 20% to 30% wool (woolen material, lamb&#39;s wool, merino wool, pima wool), and 20% to 30% cotton. 
     Subsequently, the step S 140  of entangling the knitted web  210  and the first reinforcing fiber and entangling the knitted web  210  and the second reinforcing fibers is a step of mixing the first reinforcing fibers and the second reinforcing fibers with the knitted web  210  using the needle punching machine  20  illustrated in  FIG.  16    to form a needle fabric. 
     The first reinforcing fibers of the first reinforcing portion  220  and the second reinforcing fibers of the second reinforcing portion  230  have a property of being entangled with each other, the first reinforcing fibers and the second reinforcing fibers may be introduced into the yarn of the knitted web  210  through the needling process using the needle punching machine  20  to be entangled and coupled the yarn. The present disclosure is not limited thereto, and the first reinforcing portion  220  and the second reinforcing portion  230  may be coupled using an adhesive. 
     The first reinforcing fibers of the first reinforcing portion  220  and the second reinforcing fibers of the second reinforcing portion  230  may fix the yarn of the tissue of the knitted web  210  while filling the inside or the tissue of the knitted web  210 . Since the first reinforcing fibers and the second reinforcing fiber are thinner than the yarn, the first reinforcing fibers and the second reinforcing fiber may be easily introduced into the yarn. 
     The number of times of the needling processes may be changed depending on the characteristics of the cuttable knitted fabric  200 , and 5 to 20 times of the needling processes may be performed to couple the knitted web  210 , the first reinforcing portion  220 , and the second reinforcing portion  230 . 
     Here, the needling process may be performed while a separate adhesive is supplied to the knitted web  210 , the first reinforcing fibers, and the second reinforcing fibers. The adhesive may increase bonding strength between the first and second reinforcing fibers and the knitted web  210 . 
     Subsequently, the post-treatment step S 150  is a step of supplying moisture to the needle fabric using the heat treatment machine  30  illustrated in  FIG.  17    and applying a predetermined temperature to perform drying and curing. The post-treatment step may be performed by an appropriate method depending on the use of the knitted fabric. 
     As an example, the cuttable knitted fabric  200  may be treated by immersion in water. In this case, hot water and cold water may be used as the water. Here, the hot water is water at a temperature higher than room temperature, and may be water of 40 to 80° C. The cold water is water at a temperature lower than room temperature, and may be water of 10 to 20° C. The cuttable knitted fabric  200  may be treated by alternately immersing the knitted fabric  200  in the hot water and the cold water. The cuttable knitted fabric  200  may be shrunk in advance through the post-treatment. Accordingly, the cuttable knitted fabric  200  may be reduced in shrinkage during use. 
     In addition, the cuttable knitted fabric  200  may be immersed in a soap solution and rubbed against each other. The soap solution may be maintained at a temperature of 40 to 80° C. The cuttable knitted fabric  200  is rubbed against each other in a state of being immersed in the soap solution, the reinforcing fibers are tangled, and thus, the bonding force between the reinforcing fibers and the knitted web  110  may be increased. In addition, the cuttable knitted fabric  200  may be immersed in soap solution and contracted while rubbing and thickened. The cuttable knitted fabric  200  may have a dense texture and a softer feel. 
     In addition, the cuttable knitted fabric  200  may be treated by spraying water or spraying high-temperature and high-pressure steam. In this case, the steam temperature may be 120° C. to 150° C. The heat treatment temperature after spraying the steam may be 100° C. to 180° C. The steam process and the heat treatment process may be alternately performed. The present disclosure is not limited thereto, and the steam process may be performed 5 times, and the heat treatment process may be performed 10 times. That is, the heat treatment process may be performed twice per one steam process. By adjusting the number of steam processes and the number of heat treatment processes, the feel and strength of the cuttable knitted fabric  200  can be adjusted.

The second reinforcing portion  230  disposed to correspond to the edge of the knitted web  210  may be formed of a fibrous material having high rigidity to prevent the knit of the knitted web  210  from being unraveled. The third reinforcing portion  240  is for further strengthening the rigidity of the second reinforcing portion  230 , and the third reinforcing portion  240  is disposed below the second reinforcing portion  230  to prevent the knit of the knitted web  210  from being unraveled. 
     According to the shape of the cuttable knitted fabric  200 , the shapes of the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  are variously changed (for example, circular, oval, quadrangular, rhombus, trapezoid, or the like. 
     The first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  may support the knitted web  210  as a whole to prevent curl-up from occurring. In addition, in the cuttable knitted fabric  200 , the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  are coupled to the knitted web  210 , and thus, the yarn of the knitted web  210  and the reinforcing fibers constituting the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  are entangled with each other. 
     Here, the directions of the tensile strength of the second reinforcing portion  230  and the third reinforcing portion  240  are formed to be different from each other. Accordingly, even when the knitted web  210  extends in the X-axis direction, the Y-axis direction, and the diagonal direction, it is possible to maintain the shape of the knitted web  210 - 2  and prevent the knit of the knitted web  210 - 2  from being unraveled. 
     Since the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  fix the knitted web  210 , the yarn is not unraveled even when the yarn of the knitted web  210  is cut during the cutting process. In addition, since the cuttable knitted fabric  200  is formed by having the knitted web  210  as a basic skeleton and coupling the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  using reinforcing fibers as a material, the knitted fabric  200  has good elasticity and flexibility and do not wrinkle. The knitted web  210  may be formed by woven in a substantially plate shape using a single yarn. 
     The reinforcing fibers of the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the reinforcing fibers may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the reinforcing fibers may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     The cuttable knitted fabric  200  of the present disclosure can be cut into various sizes and shapes, and thus, the knitted fabric can be used as a material for various products. As illustrated in  FIG.  6   , the cuttable knitted fabrics  200 ,  200 - 1 , or  200 - 2  may be used in the manufacture of clothing such as a sweater or a coat, a handbag, and accessories such as bags. 
       FIG.  14    is a process diagram for the method for manufacturing the cuttable knitted fabric illustrated in  FIG.  12   . 
     Referring to  FIGS.  12  and  14   , the method for manufacturing a cuttable knitted fabric  200  may include a step S 210  of providing the knitted web, a step S 220  of disposing the first reinforcing fiber, a step S 230  of disposing the second reinforcing fiber, a step S 240  of disposing the third reinforcing fiber, a step S 250  of entangling the knitted web  210  with the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers, and a post-treatment step S 260 . 
     The step S 210  of providing the knitted web is a step of preparing the knitted web  210 . The knitted web  210  may have an appropriate size and shape according to the required fabric. The knitted web  210  may be formed in a plate shape. The knitted web  210  may be formed from a single yarn by using the hand knitting machine  10  illustrated in  FIG.  15   . 
     The knitted web  210  may be produced with a weaving thickness of 5 mm to 12 mm using the hand knitting machine  10 . The length of the knitted web  210  in the first direction may be formed to be 50 cm to 150 cm, and the length in the second direction may be formed to be 100 cm to  250  cm. The present disclosure is not limited thereto, and the length of the knitted web  210  in the first direction and the second direction is not limited. Since the size is reduced by steam and heat treatment during the manufacturing process of the cuttable knitted fabric  200 , in consideration of the reduced length, the length of the knitted web  210  in the first direction and the second direction may be set. 
     Subsequently, the step S 220  of disposing the first reinforcing fiber is a step of disposing the first reinforcing fibers at regular intervals on the lower surface of the knitted web  210 . The first reinforcing fibers may be disposed to correspond to the central portion of the lower surface of the knitted web  210 . The first reinforcing portion  220  may be formed through the first reinforcing fibers. 
     The first reinforcing fibers of the first reinforcing portion  220  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the first reinforcing fibers of the first reinforcing portion  220  may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the first reinforcing fiber of the first reinforcing portion  220  may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% wool (woolen material, lamb&#39;s wool, merino wool, pima wool). 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% cotton. 
     As an example, in order to increase the tensile strength in the first direction of the cuttable knitted fabric  200 , the first reinforcing portion  220  may be formed of the first reinforcing fibers obtained by mixing 40% to 60% poly (for example, nylon) cotton, 20% to 30% wool (woolen material, lamb&#39;s wool, merino wool, pima wool), and 20% to 30% cotton. 
     Subsequently, the step S 220  of disposing the second reinforcing fiber is a step of disposing the second reinforcing fibers on the edge of the lower surface of the knitted web  210 . The second reinforcing fiber may be disposed to surround the periphery of the first reinforcing portion  220 . The second reinforcing portion  230  may be formed through the second reinforcing fibers. 
     The second reinforcing fibers of the second reinforcing portion  230  may be formed of a material having its own entanglement such as a fine fiber, a thread, or a fiber thinner than the yarn. 
     As an example, the first reinforcing fibers of the second reinforcing portion  230  fibers may be formed of wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton wool, or poly (for example, nylon) cotton. 
     As an example, the first reinforcing fibers of the second reinforcing portion  230  may be formed by mixing two or more materials selected from wool (woolen material, lamb&#39;s wool, merino wool, pima wool), cotton, and poly (for example, nylon) cotton. 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the first reinforcing fibers obtained by mixing at 50% to 70% poly (for example, nylon) cotton and 30% to 50% wool (woolen material, lamb&#39;s wool, merino wool, pima wool). 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the second reinforcing fibers obtained by mixing 50% to 70% poly (for example, nylon) cotton and 30% to 50% cotton. 
     As an example, in order to increase the tensile strength in the second direction of the cuttable knitted fabric  200 , the second reinforcing portion  230  may be formed of the second reinforcing fibers obtained by mixing 40% to 60% poly (for example, nylon) cotton, 20% to 30% wool (woolen material, lamb&#39;s wool, merino wool, pima wool), and 20% to 30% cotton. 
     Subsequently, the step S 230  of disposing the third reinforcing fiber is a step of disposing the third reinforcing fibers on the lower surface of the second reinforcing fibers. The third reinforcing fiber may be disposed below the second reinforcing fiber so as to surround the periphery of the first reinforcing portion  220 . The third reinforcing portion  240  may be formed through the third reinforcing fibers. 
     Subsequently, the step S 250  of entangling the knitted web  210 , and the first reinforcing fiber, the second reinforcing fiber, and the third reinforcing fiber is a step of mixing the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers with the knitted web  210  using the needle punching machine  20  illustrated in  FIG.  16    to form the needle fabric. 
     The first reinforcing fibers of the first reinforcing portion  220 , the second reinforcing fibers of the second reinforcing portion  230 , and the third reinforcing fibers of the third reinforcing portion  240  have a property of being entangled with each other, the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers may be introduced into the yarn of the knitted web  210  through the needling process using the needle punching machine  20  to be entangled and coupled to the yarn. The present disclosure is not limited thereto, and the first reinforcing portion  220 , the second reinforcing portion  230 , and the third reinforcing portion  240  may be coupled using an adhesive. 
     The first reinforcing fibers of the first reinforcing portion  220 , the second reinforcing fibers of the second reinforcing portion  230 , and the third reinforcing fibers of the third reinforcing portion  230  may fix the yarn of the tissue of the knitted web  210  while filling the inside or the tissue of the knitted web  210 . Since the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers are thinner than the yarn, the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers may be easily introduced into the yarn. 
     The number of times of the needling processes may be changed depending on the characteristics of the cuttable knitted fabric  200 , and 5 to 20 times of the needling processes may be performed to couple the knitted web  210 , the first reinforcing portion  220 , and the second reinforcing portion  230 . 
     Here, the needling process may be performed while a separate adhesive is supplied to the knitted web  210 , the first reinforcing fibers, and the second reinforcing fibers. The adhesive may increase bonding strength between the first reinforcing fibers, the second reinforcing fibers, and the third reinforcing fibers, and the knitted web  210 . 
     Subsequently, the post-treatment step S 260  is a step of supplying moisture to the needle fabric using the heat treatment machine  30  illustrated in  FIG.  17    and applying a predetermined temperature to perform drying and curing. The post-treatment step may be performed by an appropriate method depending on the use of the knitted fabric. 
     As an example, the cuttable knitted fabric  200  may be treated by immersion in water. In this case, hot water and cold water may be used as the water. Here, the hot water is water at a temperature higher than room temperature, and may be water of 40 to 80° C. The cold water is water at a temperature lower than room temperature, and may be water of 10 to 20° C. The cuttable knitted fabric  200  may be treated by alternately immersing the knitted fabric  200  in the hot water and the cold water. The cuttable knitted fabric  200  may be shrunk in advance through the post-treatment. Accordingly, the cuttable knitted fabric  200  may be reduced in shrinkage during use. 
     In addition, the cuttable knitted fabric  200  may be immersed in a soap solution and rubbed against each other. The soap solution may be maintained at a temperature of 40 to 80° C. The cuttable knitted fabric  200  is rubbed against each other in a state of being immersed in the soap solution, the reinforcing fibers are tangled, and thus, the bonding force between the reinforcing fibers and the knitted web  110  may be increased. In addition, the cuttable knitted fabric  200  may be immersed in soap solution and contracted while rubbing and thickened. The cuttable knitted fabric  200  may have a dense texture and a softer feel. 
     In addition, the cuttable knitted fabric  200  may be treated by spraying water or spraying high-temperature and high-pressure steam. In this case, the steam temperature may be 120° C. to 150° C. The heat treatment temperature after spraying the steam may be 100° C. to 180° C. The steam process and the heat treatment process may be alternately performed. The present disclosure is not limited thereto, and the steam process may be performed 5 times, and the heat treatment process may be performed 10 times. That is, the heat treatment process may be performed twice per one steam process. By adjusting the number of steam processes and the number of heat treatment processes, the feel and strength of the cuttable knitted fabric  200  can be adjusted. 
     In the knitted fabric and the method for manufacturing the same according to the present disclosure, it is possible to prevent the yarn constituting the knitted web from being unraveled and cut the knitted fabric into a necessary shape. 
     In the knitted fabric and the method for manufacturing the same according to the present disclosure, it is possible to increase the strength by the reinforcing portion. 
     In the knitted fabric and the method for manufacturing the same according to the present disclosure, it is possible to provide the cuttable knitted fabric to be suitable for various shapes and various uses.
