Abstract:
A double-layer directed sweat cloth, especially a quick hygroscopic sweat cloth, is disclosed. Sweat drawn by a lining is given a directional route for transporting and delivering quickly to an external dissipation layer for evaporation and sweat transferred is prevented from staining reversely a skin surface, forming a dry-wet separation effect to keep a lining layer dry. In the lining layer, part of core sections of yarns which absorb sweat are at same positions in the dissipation layer, allowing water liquid affinitive to the lining to directly acquire a directional route that sweat is quickly transported and carried outward to keep skin dry, by a co-core capillary effect to transport sweat directly and collapsing sweat beads at far ends. Moreover, as drawing yarns are woven hollowly, a hollow portion is formed in the lining to provide a dry-wet separation mechanism, maintaining dryness to skin where the cloth is worn on.

Description:
BACKGROUND OF THE INVENTION 
       [0001]    a) Field of the Invention 
         [0002]    The present invention relates to a double-layer directed sweat cloth and more particularly to a sweat cloth structure which is able to quickly expel sweat and is provided with a dry-wet separation effect, especially that sweat which is forcefully drawn in a lining is distributed directionally to a hydrophobic dissipation layer for evaporation, such that sweat can be expelled quickly and that an explicit dry-wet separation mechanism is provided between the lining and the dissipation layer, wherein sweat is expelled primarily through simultaneous drainage with plural routes, thereby being expelled quickly. 
         [0003]    b) Description of the Prior Art 
         [0004]    Since the beginning of human history, a requirement of comfortableness in wearing clothes has stimulated progressiveness of textile industries. Recently, there is an improved outcome to a sweat cloth, wherein a primary ingredient of the cloth is based upon a polyester fiber due to that the polyester fiber is hydrophobic and is able to absorb water through a special processing. 
         [0005]    A fundamental concept of the sweat cloth is that the sweat cloth is provided with a lining of hygroscopic layer and an external sweat dissipation layer between which is interwoven into a single cloth. The object is that the hygroscopic layer can be affinity to skin to draw and deliver sweat coming from a human body to the external dissipation layer. A drawing layer must be provided with capillarity and if braided wires are polyester fibers then the drawing layer can be formed with a capillary or porous adsorption effect through a chemical or physical treatment, so as to achieve a water drawing function or to achieve a capillary drawing capability through a blended fabric of natural cotton fibers. However, the blended fabric of natural cotton fibers scales off easily by a mechanical force of washing. As a result, recently, the lining layer employs a polyester fiber of an anisotropic cross section to serve as a capillary water absorption function, thereby achieving an object of expelling sweat. On the other hand, the external layer uses the braided wires which are made by twirling the polyester fiber to weave into an interlaced structure, a special hydrophobicity of which is utilized to achieve the object of quickly evaporating and expelling sweat as a water film formed by sweat spreading that sweat can be evaporated in a large area. 
         [0006]    The overall object is to provide a sweat cloth, allowing sweat, which comes out after a user wears the cloth to take an exercise, to be drawn to be carried outward, such that skin can be dry and further keep warm, thereby maintaining health. The achievement of the object can even prevent germs from growing due to wetness and warmth and form air permeability as there is no water in interwoven gaps of the cloth. 
         [0007]    The Japanese TEIJIN Limited Company has proposed plural kinds of cloth fiber technologies and also claimed the sweat cloth and fiber. That patent discloses a water guiding design between an inner and an outer layer of cloth and a water guiding design in an interlining. The company has proposed plural kinds of patent technologies of cloth and fiber and fulfilled market demands. 
         [0008]    In addition, an Asian company has disclosed a cloth which is provided with ingredients of different proportions, forming an inner and an outer layer. The cloth also provides sweat removing for sporting, according to a function of water distribution, wherein part of braided wires use two wires to interweave with a different den, but sections of the braided wires which draw sweat and wind toward a surface layer cannot be assisted by other elements and as drawing braided wires are attached to yarns at an external layer, a feedback must occur when the yarns at the surface layer are fully loaded or due to a function of gaps, allowing the drawing braided wires to regain moisture, thereby losing an object of sweat removing. 
         [0009]    A conventional knitted sweat cloth is generally shown in  FIG. 3 , wherein a surface and an interior of a cloth  8  is formed with a first and a second surface  81 ,  82 , the second surface  82  includes braided wires which are braided into plural hoops  820  in a full stitch and bottom wires of the first surface  81  are interwoven with capillary water absorbing braided wires  810  which are distributed horizontally in a shape of yarns. As sweat which is drawn by the braided wires  810  can be only submitted at dot-shaped tiny sections at overlapping portions  80 , it is difficult to satisfy a demand of evaporation of the second surface  82 . 
       SUMMARY OF THE INVENTION 
       [0010]    The primary object of the present invention is to provide a sweat cloth with a dry-wet separation operation, wherein among interwoven hoops of a dissipation layer, part include drawing hoops and complex braided hoops which are directly extended and configured from a lining layer, allowing sweat which is drawn in the lining layer can be drained and transported in a high speed to the interwoven hoops of the dissipation layer, forming water films immediately that sweat can be quickly evaporated, according to a draining operation of drawing yarns and complex braided wires which provide a capillary function with a same strand and a single core, as well as provide a simultaneous drawing structure of plural routes. 
         [0011]    A second object of the present invention is to provide a double-layer directed sweat cloth, wherein a core portion of the drawing yarn in the lining layer is an arched section, an interior of which is formed with a hollow portion to serve as a basis of a spacing of dry-wet separation. 
         [0012]    A third object of the present invention is to provide a double-layer directed sweat cloth, wherein between the neighboring arched sections in a series is spaced with a groove which serves as a dry-wet separation in a beginning when skin sweats; whereas, when sweat is accumulated into grains (sweat beads), sweat can be quickly drained through plural interwoven routes at a bottom of the groove. 
         [0013]    To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0017]    The present invention discloses a double-layer directed sweat cloth, especially a sweat cloth which forces sweat drawn in a lining to be quickly distributed to a hydrophobic dissipation layer directionally for evaporation and prevents sweat after distribution from reversely staining skin to maintain dryness of a lining layer and result in dry-wet separation in time. 
         [0018]    To achieve the aforementioned object, among interweaving of the dissipation layer  100  and the lining layer  10 , the lining layer  10  is directly extended with drawing hoops  21  which are positioned in interwoven hoops  41  of the dissipation layer  100 . The lining layer  10  is formed inward (a bottom surface) with arched sections  20  which are affinitive to skin, and sweat which is drawn by the arched sections  20  can be distributed directly to the belonging drawing hoops  21 , which are close to the interwoven hoops  41  of the dissipation layer  100 , according to a capillary function in a same strand and a single core. Next, by a guiding function of neighboring gaps between the drawing hoops  21  and the interwoven hoops  41 , an adhesion property of water liquid and an effect of pressure balance, sweat which is entrapped by the drawing hoops  21  can be effectively diffused and spreading to surfaces of the interwoven hoops  41  to form water films; thus, an evaporation area is enlarged, allowing water molecules of the water films to be more active to jump and scatter for evaporation. 
         [0019]    On the other hand, grooves  7  of the lining layer  10  do not operate explicitly in a beginning when skin sweats, with sweat only being expelled by drawing yarns  2 . However, when skin sweats a lot, sweat is accumulated into sweat beads  5  which must be expelled out quickly; whereas, one of routes for expelling out the sweat beads  5  is at the arched sections  20  of the drawing yarns  2  and the other one is at the grooves  7 . 
         [0020]    Referring to  FIG. 1  and  FIG. 2  at a same time, a sweat cloth  1  disclosed by the present invention is provided with the dissipation layer  100  and the lining layer  10 , wherein the lining layer  10  is clung to and interwoven at an inner surface (a bottom of the cloth) of the dissipation layer  100 ; this inner surface is affinitive to skin where the cloth is worn on. 
         [0021]    The said dissipation layer  100  is braided into interwoven hoops  41  by plural columns of interwoven wires  4  in a full stitch, interweaving into a base of the cloth. 
         [0022]    Complex braided wires  3  are also braided into complex braided hoops  31  which are similar to the interwoven hoops  41  of the interwoven wires  4 , with a difference that the complex braided wires  3  are knitted intermittently in a slip stitche, such as using an intermittent ratio of slipping two stitches and knitting two stitches or as many as an intermittent slip-stitch knitting with ten stitches or a various ratio of a number of slip stitches and a number of knitted stitches, like 2:3 or 3:5; a result is that plural kinds of textures of different widths can be knitted to alter patterns of textures. 
         [0023]    The aforementioned description is that the ratio of slip stitches is chosen for the complex braided wires  3  with an intermittent program to braid complexly with the interwoven wires  4  in the intermittent way, with a position of the complex braiding at a needle position of L 1 . 
         [0024]    Through the aforementioned procedure, the needle position of L 1  is simultaneously braided with the interwoven hoop  41  of the interwoven wire  4  and the complex braided hoop  31  of the complex braided wire  3 , where the interwoven hoop  41  is interwoven with the complex braided hoop  31 . At this moment, a needle position of L 2  of an alternate slip-stitch only exists with an independent interwoven hoop  41  of the interwoven wire  4 . 
         [0025]    Regarding to weaving the drawing yarns  2  of the lining layer  10  with the dissipation layer  100 , the drawing yarns  2  are used to pick up a stitch at the needle position of L 2  of the aforementioned slip-stitch, allowing the independent interwoven hoop  41  of the interwoven wire  4  to be combined with the drawing hoop  21  of the drawing yarn  2 , with a shape of the drawing hoop  21  similar to that of the complex braided hoop  31  of the complex braided wire  3 . 
         [0026]    In principle, the needle positions of the drawing hoop  21  and the complex braided hoop  31  are staggered; that is, the drawing hoop  21  and the complex braided hoop  31  of the complex braided wire  3  are staggered at a different location. In other braiding requirement of the cloth, the drawing hoop  21  and the complex braided hoop  31  are allowed to be weaved at the same needle position. 
         [0027]    The lining layer  10  is braided with the dissipation layer  100  by the drawing yarns  2  through the aforementioned knitting method. Toward an inner side (a bottom of the cloth) is preserved with the intermittent arched sections  20  which are formed directly from sections of the drawing yarns  2 . In addition, through serial knitting, the arched sections  20  are serially arranged into the grooves  7  at a left and right side and a depth of the grooves  7  is dependent on a height that the arched sections  20  arch. A hollow portion  6  is formed by using a space between the arched section  20  and the groove  7 , allowing an interlining layer to be formed on a skin surface after a user wears on the cloth, thereby effectively preventing sweat of the dissipation layer  100  from reversely staining the skin surface where the cloth is worn on. 
         [0028]    On the other hand, regarding to a dry-wet separation operation of sweat removing, it is primarily that the drawing yarns  2  provided in the lining layer  10  are normally provided with the capillary function. Using a same and a single strand and based on the arched sections  20 , the drawing yarns  2  are continuously extended toward the dissipation layer  100  to be braided with the drawing hoops  21  at the interwoven hoops  41 , with a shape of the drawing hoop  21  roughly same as the interwoven hoop  41 . Therefore, sweat which is drawn at the arched sections  20  will be directly distributed to the drawing hoops  21  along a route of a same axis and a single core by a principle of capillary pressure difference; during the transportation, there is no need to jump over any gap, like along a single core route of a body of the arched section  20 , and sweat can be smoothly transported to the drawing hoops  21 . 
         [0029]    A side of the drawing hoop  21  at the dissipation layer  100  is exposed outward, a shape of the drawing hoop  21  is about same as or smaller than that of the interwoven hoop  41  and the drawing hoop  21  is close to the interwoven hoop  41 , between them is formed with a coalesced capillary. Sweat which is drained into will be spreading and distributed on a wiring surface of the interwoven hoop  41  by adhesion of the sweat itself and an effect of pressure balance, forming a diffusive distribution in a water film shape. The interwoven hoop  41  is hydrophobic and according to an evaporation principle of water liquid, under a lower temperature and that water molecules are not frozen, as long as that the water molecules are not subjected to a strong pressure, they still have an active, jumping and scattering capability. Therefore, after sweat on the surface of the interwoven hoop  41  forms the water film, an internal pressure of sweat will become smaller and energy of the water molecules will be able to fight against that pressure to scatter and evaporate, thereby quickly dissipating sweat. 
         [0030]    Besides, as described above, regarding to the primary work load of the grooves  7 , in the beginning when skin sweats, the drawing yarns  2  will take the burden and when skin sweats a lot, in addition to that the drawing yarns  2  will still be responsible for expelling sweat, a larger quantity of sweat is submitted to the grooves  7 ; whereas, in the beginning stage when skin sweats, as the grooves  7  do not contact with skin and thus are suspended, the grooves  7  do not take burden in absorbing water temporarily. 
         [0031]    The operation of expelling sweat in a large quantity by the grooves  7  occur when skin sweats a lot. As sweat will be attached on a skin surface due to a cohesion force and adhesion ability of water liquid and will be accumulated as grain-shaped sweat beads  5 . The sweat beads  5  which are located at the arched sections  20  of the drawing yarns  2  will be directly drained to flow to the dissipation layer  100  by the drawing yarns  2 ; whereas, for the sweat beads  5  which are located at the grooves  7 , as the sweat beads  5  have a grain size and when the grain size becomes larger and is able to meet a contact distance to a bottom of the grooves  7 , an upper surface curve of the sweat beads  5  will touch the bottom, which is formed by interweaving bottom wires  30  extended from the complex braided wires  3  with bottom loops  22  extended from the drawing yarns  2 , of the grooves  7 , and the sweat beads  5  will touch the bottom and will be collapsed quickly to be drained toward the dissipation layer  100 , through the pressure and the capillary function. 
         [0032]    The base structure of the bottom is the bottom wires  30  which are extended from the complex braided wires  3  and the bottom loops  22  which are extended from the drawing yarns  2 . A left and right end of the bottom are extended respectively toward the dissipation layer  100  with the complex braided hoops  31  and the drawing hoops  21  which are provided with a similar shape as that of the interwoven hoops  41  of the interwoven wires  4  and are close together. Therefore, sweat which is drawn by the complex braided hoops  31  and the drawing hoops  21  can be quickly delivered to the interwoven hoops  41  for dissipation by water spreading and the capillary phenomenon. 
         [0033]    The said bottom wires  30  are in a straight line shape, flat located at an intersection between the lining layer  10  and the dissipation layer  100  due to slip-stitch in spacing. In addition, the bottom wires  30  belong to the lining layer  10  and two sides are extended with the complex braided hoops  31  which are complexly braided at the same positions as the interwoven hoops  41 . The said bottom loops  22  are formed by knitting the drawing yarns  2 ; that is, the bottom loops  22  are formed by extending downward the interwoven hoops  41 , with a bottom contact point of the bottom loops  22  being intersected with the flat bottom wires  30 . 
         [0034]    The operation of massively and quickly expelling the sweat beads  5  is that when the sweat beads  5  are accumulated, as described above, such that the grain size is large enough to touch the bottom of the grooves  7 , especially that the sweat beads  5  are exactly at the intersected positions between the bottom loops  22  and the bottom wires  30 , along with the capillary function of the wirings and a gap effect among interweaving of the wirings; then there will be four draining routes in total from the left and right ends of the bottom wires  30  and two sides of the bottom loops  22  up in a curved direction and with convenience of directly delivering along the wiring of a single core and a same strand by the capillary function, that the sweat beads  5  per unit volume can be quickly collapsed to shunt and drain to each extended complex braided hoop  31  and the drawing hoop  21 . The aforementioned diffusion and delivering operation is repeated to expel sweat which is evaporated quickly at the interwoven hoops  41  of the dissipation layer  100 . 
         [0035]    In the aforementioned evaporation process, if the water film on the surface of the interwoven hoop  41  is evaporated off, then sweat which is entrapped by the complex braided hoops  31  and the drawing hoops  21  will acquire a different pressure position to be diffused in balance again, enabling the water film which is once more distributed on the surface of the interwoven hoops  41  to be ready for the repeated evaporation cycle or the sequential operation. 
         [0036]    If the aforementioned operation is added by a relative speed of body movement with respect to air or blowing of natural wind, then a streamline of outside air will enter into an inner ring of the drawing hoop  21  and the interwoven hoop  41  to form turbulence and a shock force which are beneficial to partly evaporate sweat in advance. As a result, a semi-loop shape of the interwoven hoop  41  and the drawing hoop  21  is necessary to explicitly aid the evaporation. 
         [0037]    The aforementioned dissipation layer  100  is provided with a good evaporation efficiency and under a condition that sweat is carried easily, air will flow throughout the sweat cloth  1  easily, enabling the sweat cloth  1  to be provided with a smooth breathing and air permeable function. 
         [0038]      FIG. 1  shows a structure of braided yarns of a cloth of the present invention, which is ended up as the cloth in  FIG. 2  after interweaving plural columns of the yarns. In general, the cloth is provided with an inner and an exterior surface and in the present invention, the inner surface is defined as the lining layer  10 ; whereas, the exterior surface is defined as the dissipation layer  100 . The lining layer  10  utilizes the drawing yarns  2  and complex braided wires  3  which form directly the drawing hoops  21  and the complex braided hoops  31  during the braiding process, and are braided at same locations in the interwoven hoops  41  that are braided by the interwoven wires  4  of the external dissipation layer  100 , allowing the drawing hoops  21  and the complex braided hoops  31  to face respectively the interwoven hoops  41  and to be knitted at each needle position, such that sweat which is drawn by the lining layer  10  can be directly transported to the drawing hoops  21  and the complex braided hoops  31 , along the same axis of the single core strand of the drawing yarns  2  and the complex braided wires  3 , following the direct route and through the capillary function. As a result, sweat can be drained in a high speed, along with an interaction of the drawing hoops  21  and the complex braided hoops  31  with the interwoven hoops  41 , that sweat can be evaporated quickly. 
         [0039]    The lining layer  10  and the dissipation layer  100  of the present invention are that the lining layer  10  includes the arched sections  20  and the bottom of the grooves  7 , with the bottom being formed by intersecting the bottom loops  22  with the bottom wires  30 ; the dissipation layer  100  includes the interwoven hoops  41  of the interwoven wires  4 , the drawing hoops  21  and the complex braided hoops  31 . In addition, the lining layer  10  is provided with the hollow portion  6  and sweat which is drawn can be transported outward quickly to the dissipation layer  100  along the direct route; whereas, the dissipation layer  100  allows sweat to be evaporated by the outside air flow or a vibration effect of thermo-electromagnetic waves, and thus, the dissipation layer  100  can keep dry quickly due to the rapid transportation of sweat. 
         [0040]    In terms of sweat evaporation efficiency, in principle, the larger the diffusion area, the more easily sweat is evaporated. To enhance the evaporation efficiency of the water film formed by sweat, a number of dens or wire diameter of the interwoven wires  4  can be increased to forcefully increase a surface area, allowing sweat per unit volume to have a larger area to be distributed into thinner water films, as water molecules inside the thinner water films can have stronger activity to jump and evaporate. 
         [0041]    Besides, by changing a number of dens of the braided wires, a various degree of capillary can be formed, as well. In the present invention, numbers of strands of the interwoven wires  4  or the complex braided wires  3  relative to the drawing yarns  2  are implemented to be non-proportionally matched. For example, if a length and a weight of the interwoven wire  4  and the drawing yarn  2  are equal, then  144  strands of the interwoven wire  4  will be used, whereas  36  strands of the drawing yarn  2  are used. Therefore, the capillary effect of the interwoven wire  4  will be larger than that of the drawing yarn  2 , which is easy to disperse the hydraulic pressure, relatively allowing the water liquid in the drawing yarns  2  to quickly seek for places of a lower pressure difference for delivering. In addition, the capillary effect is stronger and a larger space to store water is relatively provided, allowing sweat of the drawing yarns  2  to be transferred in a high speed and in a large quantity. Therefore, sweat which is drawn by the drawing yarns  2  will quickly flow outward to maintain dryness. 
         [0042]    The basis of concept of the present invention is to directly use the drawing hoops  21  and the complex braided hoops  31  which are formed by extending part of sections of the drawing yarns  2  and the complex braided wires  3  in the lining layer  10 , to be braided in the interwoven hoops  41  provided by the dissipation layer  100 , allowing sweat which is drawn by the lining layer  10  to be directly transported to the dissipation layer  100  along the core of wirings and to be quickly delivered to the interwoven hoops  41  of the dissipation layer  100 , by the adhesion and spreading abilities of sweat, thereby achieving an object of quickly diffusing and evaporating sweat. Furthermore, by using the hollow portions  6  inside the arched sections  20  of the drawing yarns  2  and the hollow spaces formed in the grooves  7  between the neighboring arched sections  20 , the dry-wet separation support is formed between the lining layer  10  and the dissipation layer  100  in dissipating sweat, allowing the lining layer  10  to maintain dryness to skin where the cloth is worn on and sweat of the dissipation layer  100  to be dissipated as much as it can be without flowing back; which is actually the innovative braided structure of the sweat cloth  1 . 
         [0043]    It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
