Description:
TECHNICAL FIELD 
     The present disclosure relates to the technical field of fabric, and specifically to a method for manufacturing a fabric with an intelligently-designed digitally-printed pattern with energy saving effect. 
     BACKGROUND ART 
     Currently, the digital printing presents a trend that the printing speed of equipment is becoming faster, the cost of nozzles is becoming lower, the application mode is well-development, and the automation stability of equipment is getting better. Driven by the application of digitization and automation and big data, there is a trend that screen printing would be replaced by digital printing among traditional printing and dyeing enterprises. Many printing and dyeing enterprises, more or less, have bought digital printing and dyeing devices. However, the informatization level of the production line is not high. The future development trend of digital ink-jet printing industry in China is that the equipment and technology will be further improved, the cost will be further reduced, and the market will be further expanded. 
     The integration of manufacturing industry and the Internet is in line with the national industrial policy. It is a project encouraged by the government aiming to establish a hardware development and manufacturing system of the whole industrial chain, that is, a manufacturing system centering on small and medium batch orders involving design and development, digital printing, and clothing style design and manufacture. In this system, the service process, manufacturing process, and delivery process are informationized and networked. Artificial intelligence pattern design and design tools are provided, and a new type of sale and new design are formed, which could create a convenient website platform for enterprises to complete product development and manufacturing, processing and delivery and other services online. 
     For example, the tie-dyed fabric have been widely used in fashion clothing because of its unique visual image, unfamiliar texture effect and in-depth interpretation of popular art. Traditional tie-dyed fabric was obtained by hand wrapping and dip dyeing, which needed a lot of manpower and caused serious pollution to the environment. Therefore, the process is not conducive to the current mainstream fast fashion green printing and dyeing.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     The following are the specific embodiments of the present disclosure, and the technical solution of the present disclosure is further described in combination with the drawings, but the present disclosure is not limited to these embodiments. 
     Example 1 
     The method for manufacturing the fabric with an intelligently-designed digitally-printed pattern with energy saving effect was performed as follows: 
     S1. knitting: a 65 S cotton yarn, a bamboo fiber yarn, and a mulberry silk yarn were combined to form a double strand yarn, and then the double strand yarn was knitted into a silk-cotton plain knitted single-sided fabric. The cotton yarn used was a combed long staple cotton yarn, and 46% of the long staple cotton yarn, 42% of the bamboo fiber yarn, and 12% of the mulberry silk yarn were combined to form the double strand yarn. The knitting was performed by utilizing a Chinese Taiwan single-sided great circle machine, with knitting parameters: a machine number of 32 needles/25.4 mm, a cylinder diameter of 34 inches, and a fabric width of 160 cm. 
     Compared with the ordinary cotton yarn, the combed cotton yarn is smoother, and flatter. The bamboo fiber has good moisture absorption and air permeability, strong wear resistance, and natural antibacterial, bacteriostasis, mite killing, deodorization, and ultraviolet resistance functions. The addition of mulberry silk yarn makes the fabric feel more soft, smooth, cool when it contacts with the skin, and more comfortable and breathable. 
     Further, in this example, 70S single strand long staple cotton yarn, 60D bamboo fiber yarn, and 120D mulberry silk yarn were selected and were combined to form a 65S double strand yarn. 
     In order to further improve the fabric texture, the long staple cotton yarn was singed and mercerized in the early stage. 
     S2. singeing: the fabric obtained in step S1 was subjected to a double-sided singeing. 
     Specifically, the singeing was performed with parameters: a burner pressure of 1.6 Pa and a singeing speed of 55 m/min. The singeing were uniform to prevent uneven singeing. 
     S3. mercerizing: the fabric obtained in step S2 was mercerized by utilizing a knitting mercerizing machine. 
     Specifically, the mercerizing was performed with parameters: an alkali resistant penetrating agent- 1005  with a concentration of 8 g/L, a roll alkali with a concentration of 185 g/L, a speed of 18 m/min, an unloading weight of 135 g, an overfeed of 12%, and an unloading width of 140 cm. 
     Good dimensional stability, strength, elongation, and surface gloss could be obtained after the mercerizing. 
     S4. boiling: the mercerized fabric in step S3 was subjected to a neutralizing processing, a bleaching processing, a deoxidating processing, and a whitening processing in sequence, obtaining a boiled-out fabric. 
     The neutralizing processing was performed by using 2 g/L oxalic acid, and the process curve of the neutralizing processing was shown in  FIG.  1   . 
     The bleaching was performed by using a bleach, which consisted of hydrogen peroxide with a concentration of 8 g/L, a refining agent  3001  with a concentration of 1 g/L, caustic soda with a concentration of 2.5 g/L, 1003 hydrogen peroxide stabilizer with a concentration of 0.5 g/L, and an iron ion chelating dispersant with a concentration of 1.2 g/L. 
     Specifically,  FIG.  2    shows the curve diagram of the bleaching process. The procedures of the bleaching treatment were as follows: 
     Step A: A hot water with a temperature of 40° C. was fed, 1003 hydrogen peroxide stabilizer, and an iron ion chelating dispersant were added and the system was held for 2 minutes. An alkali was then added thereto, and the system was held for 2 minutes. Hydrogen peroxide was then added and the system was operated for 2 minutes. 
     Step B: The system was heated to 70° C. Refining agent  3001  was then added thereto. 
     Step C: The system was heated to 98° C., maintained at the temperature, and operated for 40 minutes. The system was then cooled to 78° C. and the fabric was cut for a sample. The system was finally heated to 80° C. and washed by overflowing water for 10 minutes. The pH value of the drainage at the drainage outlet was measured, and the drainage and the fabric were discharged. 
     The bleaching makes the fabric smooth and clear, and uniform in whiteness. 
     Further, the capillary effect should be more than 10 cm/30 min to ensure the full reaction between fiber and dye to enhance the coloration. 
     After the bleaching, there was hydrogen peroxide residue on the yarn, which needs to be neutralized to remove the residual hydrogen peroxide on the fabric to prevent the generation of dyeing defect. Therefore, the deoxidating treatment was adopted. The deoxidating treatment was performed by using a high-efficiency deoxyenzyme at a temperature of 45° C., and the amount of the high-efficiency deoxyenzyme was 0.1 g/L. 
       FIG.  3    shows the curve diagram of the whitening treatment process. The whitening processing was performed as follows: the fabric was fed into water. An acid was added thereto, and the system was heated to 40° C. 0.6% of 4BK-S whitening agent and 0.1% of 777 fluorescent whitening agent were added thereto. The system was heated to 90° C., and operated for 20 minutes. The base fabric was whitened. The system was cooled to 78° C. and cut for a sample. Water was fed, and the fabric was washed by overflowing water for 5 minutes. The drainage and the fabric were discharged. 
     S5. setting a base color: the fabric obtained in step S4 was set a base color. 
     In order to make the printing size stable, the fabric surface flat, the printing pattern bright, and the weight and width meet the requirements, a Monforts Fong&#39;s setting machine was selected for the setting of the base color to ensure the weight and size stability. The base color was set with parameters: a temperature and a speed of 140×50° C.*m/min, an air volume of 1500 r/min, a pressure of 5 kgf/cm 2 , an overfeed of 8/0/0%, and a width and weight of 153×140 cm*g/m 2 . 
     S6. printing: The fabric processed in step S5 was subjected to a sizing and setting treatment, a pattern design treatment, a digital printing, a steaming treatment, and a water washing treatment, to obtain a printed fabric. 
     The digital printing was performed by utilizing a digital printing and drying partition processing apparatus. An ink-jet printing was performed on the pattern-designed fabric by a digital ink-jet printing system of the digital printing and drying partition processing apparatus. After the ink-jet printing, the jet-printed fabric was passed into a drying zone and dried therein. The digital ink-jet printing system and the drying zone were continuously arranged, and the digital ink-jet printing system and the drying zone were arranged in different spaces. Further, there was a connecting channel between the two spaces to facilitate the fabric to pass through. 
     Specifically, the sizing and setting treatment was performed by an impregnation to make the fabric coated with a sizing agent. In order to improve the printing uniformity, color stability, color development, and good printing effect of full bottom printing, many comparative tests and demonstrations had been carried out, and showed that the sizing agent consisted of 500 g of a self-preparation chemical synthesis paste, 30 g of sodium bicarbonate, 10 g of a colorless anti-staining salt, 30 g of sodium sulfate, 70 g of urea, 30 g of 373 hygroscopic agent, and 330 g of water. 
     The impregnation was performed with parameters: a rolling pressure determination of 3 kgf/cm 2 , an air volume of 1260 r/min, a temperature of 110° C., a speed of 40 m/min, a pick-up rate of 85%, and an overfeeding of 0/0/0%. 
     In order to ensure bright color, deep color and good fabric permeability, after many tests, the formula of the original paste was as follows. The self-preparation chemical synthesis paste was prepared from 5 kg chemical synthesis paste, 1 kg seaweed, and 95 kg water. Preferably, the paste needs to be puffed evenly, and leaving to stand overnight was to improve the expansion degree. Fabric sizing was to avoid the spread of the printed pattern, thereby achieving bright color, and high color yield. The self-preparation chemical synthesis paste was used to impart good color yield and outline clarity to the printed fabric. Further, it was soluble in water and exhibits good paste removal property, imparting soft hand feel to the printed fabric. Meanwhile, its addition leads to a slight increase in the viscosity of pad dyeing solution, thereby being more stable. The combination with sodium alginate has good water retention property, which was conducive to the adhesion of dye to the fiber. However, if its amount was too large, the coating is thicker, and it would hinder the dyeing of the fiber. 
     After the fabric was finally set, it was rolled immediately and sealed with plastic paper. 
     Specifically, as shown in  FIGS.  5  to  11   , the digital printing and drying partition processing apparatus included a fixed bottom plate  1 , a clamping traction component  2 , and a conveying component  3 ; two support plates  4 , which were vertical and symmetrically provided at the top of the fixed bottom plate  1 ; a first conveyor belt  5  and a second conveyor belt  6 , which were arranged between the two support plates  4 ; a printing machine  7 , a first dryer  8 , a steamer  9  and a second dryer  10 , which were arranged in sequence at the top of the two support plates  4  at intervals, wherein the printing machine  7  and the first dryer  8  were engaged with the first conveyor belt  5 , and the steamer  9  and the second dryer  10  were engaged with the second conveyor belt  6 ; the clamping traction component  2  was arranged at one side of one of the two support plates  4 , and an output end of the clamping traction component  2  penetrates through one of the two support plates  4  and extends between the two support plates  4 ; the conveying component  3  was arranged between the two support plates  4 .

The third fixed block  323  was horizontally installed between the two support plates  4 . Several the fourth fixed blocks  326  were arranged at the bottom of the third fixed block  323  along the length direction of the third fixed block  323  in intervals. The other end of the first rotating rod  322  successively penetrates through several the fourth fixed blocks  326  and was fixedly connected with one of the first bevel gears  324 . The other one of the first bevel gears  324  was sheathed on the first rotating rod  322  and was fixedly connected with the first rotating rod  322 . The two rising members  325  were symmetrically arranged between the two support plates  4 . The two rising members  325  were respectively rotationally matched with the two first bevel gears  324  and supported the first rotating rod  322  through several the fourth fixed blocks  326  installed at the bottom of the third fixed block  323  at intervals. 
     Specifically, each of the rising member  325  included a support rod  3251 , a fifth fixed block  3252 , a second bevel gear  3253 , a second rotating rod  3254 , a first screw  3255 , a second screw  3256 , a rising rod  3257 , a sleeve  3258 , and an arc-shaped support block  3259 . The bottom of the second rotating rod  3254  penetrated through the third fixed block  323  and was fixedly connected with the second bevel gear  3253 . The second bevel gear  3253  was engaged with the first bevel gear  324 . The first screw  3255  was arranged on the top of the second rotating rod  3254 . The support rod  3251  was arranged on one side of one of the two support plates  4 . The fifth fixed block  3252  was arranged on the top side of the support rod  3251 . The rising rod  3257  was arranged at the bottom of the fifth fixed block  3252 . The two ends of the rising rod  3257  were respectively rotationally connected with the fixed bottom plate  1  and the fifth fixed block  3252 . The second screw  3256  and the sleeve  3258  were sheathed on the rising rod  3257  in intervals, and the second screw  3256  and the sleeve  3258  were slidably connected with the rising rod  3257 . The second screw  3256  was threaded with the first screw  3255 . The arc-shaped support block  3259  was arranged on one side of the support rod  3251 . The arc-shaped support block  3259  was fixedly connected with the sleeve  3258 . The second screw  3256  was threaded with the first screw  3255 , so that when the first screw  3255  rotates, the second screw  3256  was driven to move, and then the sleeve  3258  and the arc-shaped support block  3259  were driven to move, so as to realize the transmission of the first rotating roller  218 , which eliminated the process of manual reciprocating transportation and improved the work efficiency. 
     Specifically, a groove  11  for supporting the first rotating roller  218  was formed between the second conveying rod  313  and the support rod  3251 , and the groove  11  was matched with the arc-shaped support block  3259  to limit the first rotating roller  218 , so that the arc-shaped support block  3259  could drive the first rotating roller  218  to rise. 
     The working principle of the production equipment was as follows. When the fabric over the first rotating roller  218  was printed, the air cylinder  212  was ran and drove the first motor  211  to move. Meanwhile, the clamping pillar  215  was pulled, so that the first rotating roller  218  slid down to the unloading port  314  along the length direction of the first conveying rod  312 , and then slid onto the second conveying rod  313 , and finally fell into the groove  11 .

The second screw  3256  and the sleeve  3258  were driven to move upward by the threaded connection of the first screw  3255  and the second screw  3256 . The first rotating roller  218  was thereby driven to move upward to the input end of the second conveyor belt  65  through the arc-shaped support block  3259 . Therefore, the fabric over the first rotating roller  218  could be continuously subjected to a drying, which eliminated the process of manual reciprocating transportation and improved the work efficiency. 
     Secondly, as shown in  FIG.  3    and  FIG.  7   , a U-shaped frame  12  was arranged on at an upper side of one of the two support plates  4  through a hinge point, and one end of the U-shaped frame  12  far away from the one of the two support plates  4  was provided with a V-shaped opening  13 . The U-shaped frame  12  rotated around the hinge point such that the V-shaped opening  13  is stuck on the uppermost side of the other of the two support plates  4 . A rolling curtain  14  positioned between the printing machine  7  and the first dryer  8  was connected to the U-shaped frame  12 , and a gap was left between a lower side of the rolling curtain and an upper conveying surface of the first conveyor belt  5  after unwinding the rolling curtain. 
     The roller curtain  14  could separate the printing zone from the drying zone to avoid heat transferring. Meanwhile, the printing zone was arranged in a first room, and the drying zone was arranged in a second room. The first room was communicated with the second room, and the rolling curtain could close the connected part of the two. In summer, when the air conditioner in the first room was turned on, the designed rolling curtain could be used to save energy consumption of the air conditioner.

The air outlet holes inclined to the middle of the printing machine  7  was respectively arranged on each outlet pipe  15 , and the air outlet holes were used to reduce the subsequent drying time. 
     The pattern design treatment was performed by utilizing an AI intelligent pattern design platform, for example, MiHui intelligent pattern design platform. That is to say, artificial intelligence technology was used to design the required pattern. Tens of millions of material pictures were stored in the software cloud function. After the required pattern style was input, pictures were generated at the speed of 50 patterns per minute by automatic design of artificial intelligence. Hundreds of pictures could be produced in a few minutes or an hour for customers to choose. According to the opinions of customers, the chosen pictures could be modified by adding the materials and pictures that the customers want and redesigning a new pattern draft through artificial intelligence for the customers to choose. Three-dimensional model sample clothes were generated by using automatic model dressing function in the software. Through the Mini Program function of WeChat, the sample clothes were sent to the customer to confirm the design effect, which eliminated the whole traditional process of sending the small sample to the customers for confirmation, and shortened the development time and design cost. The designed patterns were featured by high definition, wide thinking, strong three-dimensional sense, and many new styles. 
     AI intelligent pattern design brought about an improvement in design efficiency by 5 times. The popular colors could be controlled by AI intelligent online color matching, and 3D simulation effect could be displayed through one click fitting, and massive gallery were updated continuously by designers and artificial intelligence. 
     24-head high resolution digital ink-jet printing machine was used as the digital ink-jet printing system, which could automatically control the ink spots. Through the self-designed ICC density curve, the quantity of ink could be effectively controlled, and the pattern output could be obtained basically as what you see on the professional computer display. By using 600 dpi bi-directional high-precision printing mode, the pattern produced had strong three-dimensional sense, rich color, regularly-changed moire, strong artistic sense and was environmentally friendly. Further, the production speed was fast to meet fast fashion production of the market. The digital ink-jet printing was performed by using artificial intelligence design pattern(s), and the patterns were avant-garde and fashionable, deeply loved by consumers, and has strong market competitiveness. Thus, it was the first choice of fabrics for upscale brands to make summer clothing, and has a good development prospect. 
     The digital ink-jet printing machine adopted an intelligent color management system, which was performed as the following procedures: 
     a0. intelligent color matching and proofing 
     “the pattern could be obtained as what you see”. That is to say, the color of the final product was what the remote designer saw on the screen, which improved the efficiency of digital proofing, and shortened the process and cycle of sample confirmation, thereby realizing “the ink-jet printing factory on the designer&#39;s desktop”. 
     b0. With intelligent control, unified colors can be produced between networked machines 
     Among all the networked machines, colors to be printed were standardized and amount thereof were highly unified, so as to realize flexible production scheduling of one pattern by several machines and collaborative printing production. 
     c0. intelligent color verification 
     The ink-jet printed color was regularly and intelligently calibrated, and the data was tracked and compared, and the color difference was quantified and corrected by one click, which was always the same as before. At any time, for any ink-jet printing machine, products for the resubscribed order could be produced without color differences. 
     The digital ink-jet printing machine also adopted an printing system, which was digital, intelligent, and networked, and the digital ink-jet printing was performed as follows: 
     a. digital output of pattern 
     The pattern from the computer was digitally output by the digital ink-jet printing system, and the ink was controllably jetted onto the fabric according to the demand. The combination proportion of the inks was automatically quantified by the computer, and stored in the database automatically. 
     b. intelligent pattern recognition 
     Pattern features were recognized intelligently, and color printing modes were recommended automatically to match with the pattern. 
     c. intelligently matching printing process 
     The process parameters for printing pattern were saved automatically. When printing again, the original process parameters could be matched automatically. 
     d. intelligent evaluation of pattern ink consumption 
     According to color(s) of the pattern and printing process, the ink consumption of each color could be intelligently evaluated, and the ink cost and total ink consumption could be calculated. 
     e. intelligent full closed loop stepping control 
     The motion of the guide belt was tracked and detected by magnetic grating, and the compensation was calculated intelligently in real time to ensure the high-precision stepping motion of the guide belt. 
     f. intelligent nozzle protection 
     There were four kinds of nozzle protection. The height of the fabric surface and the foreign matter on the surface of guide belt were detected in real time. In case of abnormal conditions, alarm shall be given immediately, and the nozzle shall be suspended or raised to protect the nozzle. 
     g. online intelligent quality monitoring 
     In the process of the ink-jet printing, the machine vision and AI intelligence were used to monitor the quality of ink-jet printing online and give an alarm. If it was determined that the nozzle was short of ink, the nozzle cleaning procedure would be started automatically. 
     h. intelligent ink temperature-controlled system 
     The ink temperature was intelligently and circularly controlled to ensure the stable and continuous printing production of the nozzle under the constant temperature. 
     i. remote assignment of printing workflows 
     The dispatching center collects the RIP of images and remotely assign the workflows to the on-line machines to queue up for automatic printing in sequence according to the operation progress of the on-line jet printing machines. Because the colors for the ink-jet printing of each machine had been standardized and unified, the production operation could be flexibly scheduled, and multi-machine collaborative production could be realized. 
     j. remote operation and maintenance 
     The machine running faults were monitored remotely to find out the causes, and the solutions were provided. Or the program version was upgraded remotely. According to the operation time and output, maintenance and consumable replacement reminders were timely issued. 
     After the ink-jet printing was completed, the fabric was passed into the drying zone. In the drying zone, electric heating drying was used, and the temperature in the drying room was 80-90° C. 
     After drying, the fabric should be sealed with plastic paper to prevent moisture. The drying zone was separated from the ink-jet printing system, and the glass door was used in the middle to separate into two rooms, namely two different spaces. The water vapor and heat after drying were recovered through the water vapor and waste heat removal channels in the drying zone, which could effectively control the rise in temperature in the ink-jet printing zone, prevent the nozzle blockage, and reduce the air conditioning burden, thereby reducing power consumption and the energy consumption. 
     After drying, a steaming treatment was performed by using a mist type humidifier, to spray moisture and regain moisture, with a speed of 20 m/min. The humidifying was performed sufficiently and homogeneously. Due to the fine pattern, the printed fabric after regaining moisture was steamed immediately. The steaming was performed with parameters: a ring length of 2.3 m, a temperature of 105° C., a time of 10 min, a speed of 26 m/min, and a steam flow of 900 kg/h. 
     The water washing treatment was performed by utilizing a continuous rope-shaped water washing machine at a speed of 35 m/min. A padder was rinsed with water from a first cylinder and a second cylinder. The fabric was washed in a third cylinder, a fourth cylinder, a fifth cylinder, and a sixth cylinder, which were configured to contain water with a temperature of 90° C. and a soaping agent with a concentration of 4 g/L. The fabric was washed with water in a seventh cylinder and an eighth cylinder. The fabric was then dehydrated and scutched. 
     S7. soft setting: the fabric obtained in step S6 was soft set by utilizing a setting machine. 
     The soft setting was performed by utilizing a Monforts Fong&#39;s setting machine. The formula of the softener was as follows: a stiffening finishing agent of 30 g/L and a soft ice-sense finishing agent of 100 g/L. 
     The soft setting was performed with parameters: a temperature of 160° C., a speed of 40 m/min, an air volume of 1500 r/min, a pressure of 3 kgf/cm 2 , an overfeed of 15/0/3%, and an unloading width of 142 cm, and a weight of 145 g/m 2 . 
     S8. decating treatment: the fabric obtained in step S7 was subjected to a decating treatment. Under a condition of damp heat and relaxation, and a residual internal stress was eliminated. Specifically, the decating treatment was performed with parameters: a speed of 20 meters, and a temperature of 130° C. Through the above process and parameters, the fabric was stable in shape and soft in handle, and the elasticity of the fabric was increased. 
     S9. pre-shrinking treatment: the fabric obtained in step S8 was subjected to a pre-shrinking treatment by utilizing a pre-shrinking machine, to make a size change rate of water washing not more than 3%, obtaining the fabric with an intelligently-designed digitally-printed pattern. 
     The pre-shrinking treatment was performed by utilizing an Italy SANTEX pre-shrinking machine, with parameters: a temperature of 135° C., a speed of 28 m/min, a feeding fabric speed ratio of 1%, an unloading blanket speed ratio of 5%, and a cooling belt speed ratio of 1%.
