[0023] 1. The present invention discloses a water-absorbing and quick-drying school uniform fabric production process, which uses cotton fiber, polyester fiber, and viscose fiber to make water-absorbing yarn, and then uses the water-absorbing yarn to make a double-layer fabric for school uniforms.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

[0034] As shown in Figures 1 to 6 The production process of the water-absorbing and quick-drying school uniform cloth includes the following steps:

[0035] S1: cotton fibers, polyester fibers and viscose fibers are blended to obtain water-absorbing yarn 5; the use of cotton fibers improves the hydrophilicity of the water-absorbing yarn 5, and the use of the cloth made of the water-absorbing yarn 5 can quickly absorb moisture and promote surface drying after being made into a school uniform, improving the wearing comfort of the school uniform; the use of polyester fibers improves the strength of the water-absorbing yarn 5 obtained after blending, avoiding the breakage of the water-absorbing yarn 5 and affecting the use of the water-absorbing yarn 5 and the durability of the cloth made after preparation;

[0036] S2: the viscose fibers used in step S1 are extruded and cut using a pressure cutter to form a fixed distance interval groove on the surface of the viscose fibers, and the treated viscose fibers remain continuous and unbroken;

[0037] S3: the water-absorbing yarn 5 is spun into a double-layer cloth fabric using a textile equipment; the double-layer cloth fabric is used to prepare a water-absorbing and quick-drying school uniform;

[0038] The pressure cutter is heated to treat the viscose fibers, and the groove surface of the viscose fibers is melted into a whole; by heating the pressure cutter, the viscose fibers treated by the pressure cutter generate a melting effect at the position where the viscose fibers are pressed, causing the surface of the gap cut by the pressure cutter to melt and solidify, thereby avoiding the situation that the gap cut by the pressure cutter is raised and rough after the viscose fibers are cut, affecting the subsequent blending of the viscose fibers to form the water-absorbing yarn 5;

[0039] The water-absorbing yarn 5 is treated by a treatment device before being spun, and the water-absorbing yarn 5 is pressed at both ends and in a straight state during the hydrophilic finishing; the viscose fibers in the water-absorbing yarn 5 are broken at the groove after the hydrophilic finishing;

[0040] Due to the shrinkage of viscose fibers being greater than that of cotton fibers and polyester fibers, when the water-absorbing yarn 5 is compressed at both ends during the hydrophilic finishing of the water-absorbing yarn 5 and the water-absorbing yarn 5 is tightened, the viscose fibers will be affected by the notch on the viscose fibers, causing the viscose fibers to break at the notch, resulting in the viscose fibers being wrinkled, thereby forming notches or protrusions on the surface of the water-absorbing yarn 5, and further forming gaps between the water-absorbing yarn 5 and the skin of the wearer after the water-absorbing yarn 5 is made into a fabric and the fabric is made into a school uniform, which is conducive to ventilation and quick drying after sweating. At the same time, the wrinkled viscose fibers also increase the gaps between the water-absorbing yarn 5 in the fabric, increasing the porosity of the fabric, promoting ventilation and air permeability, and further promoting the evaporation and drying of sweat, thereby improving the water absorption and quick drying effect of the fabric.

[0041] As an embodiment of the present application, the warp and weft density of the surface fabric in the double-layer fabric is greater than that of the inner layer fabric;

[0042] The structure of the water-absorbing yarn 5 is a core-spun yarn, and the polyester fibers serve as the core of the core-spun yarn;

[0043] By changing the size of the warp and weft density, the density of the surface fabric in the double-layer fabric is greater than that of the inner layer fabric, and the porosity of the inner layer fabric that contacts the skin of the wearer is relatively large after the fabric is made into a school uniform, which is conducive to the absorption of sweat by the fabric, thereby improving the wearing comfort. At the same time, since the density of the surface fabric is greater than that of the inner layer fabric, the amount of cotton fibers contained in the surface fabric is greater than that of the inner layer fabric, so that the sweat absorbed by the inner layer fabric is more easily sucked into the surface fabric, which can ensure the relative dryness of the inner layer fabric that contacts the skin, improve the comfort and water absorption effect, and the sweat sucked into the surface fabric is evaporated under the action of the flow of external air, reducing the moisture content in the surface fabric and improving the quick drying effect of the fabric;

[0044] At the same time, since the polyester fibers serve as the core of the core-spun yarn, the cotton fibers in the water-absorbing yarn 5 are located at the periphery, and in the fabric made of the water-absorbing yarn 5, the cotton fibers are easily in contact with the surface of the wearer's skin, improving the comfort of wearing the school uniform and facilitating the absorption of sweat by the cotton fibers that contact the skin surface, thereby improving the water absorption and quick drying effect of the school uniform. At the same time, by wrapping the polyester fibers in the middle position of the water-absorbing yarn 5, the possibility of the polyester fibers contacting the outside can be reduced, avoiding the aging and damage of the polyester fibers, thereby improving the strength of the water-absorbing yarn 5 and the fabric.

[0045] As an embodiment of the present application, the number of cotton fibers in the water-absorbing yarn 5 is greater than the sum of the number of polyester fibers and viscose fibers, and the water-absorbing yarn 5 is subjected to sanding treatment using a brush before hydrophilic finishing;

[0046] The number of cotton fibers in the water-absorbing yarn 5 is relatively large, and the water-absorbing yarn 5 is subjected to hydrophilic finishing, so as to improve the water absorption of the cloth made of the water-absorbing yarn 5, and enable the absorbed water to be quickly transferred to the surface of the cloth and evaporated, so that the water absorption and quick drying effect of the cloth are good. At the same time, the water-absorbing yarn 5 is combed and napped by the brush, so that the water-absorbing yarn 5 is relatively loose when entering the hydrophilic finishing agent, and there are raised fiber fluffs on the surface, so as to promote the penetration of the hydrophilic finishing agent in the water-absorbing yarn 5 and improve the hydrophilic finishing effect.

[0047] As an embodiment of the present application, the processing device comprises a base 1, a processing groove is formed in the base 1, contact rollers 11 are installed at both ends of the base 1, guide rollers 12 are installed in the processing groove, the guide rollers 12 change the movement direction of the water-absorbing yarn 5, and the guide rollers 12 enable the water-absorbing yarn 5 to pass through the hydrophilic finishing agent;

[0048] Symmetrical front and rear pressure rollers 21 and 2 are installed in the processing groove, the guide rollers 12 are located between the front and rear pressure rollers 21 and 2, the front and rear pressure rollers 21 and 2 are driven by a motor 22, the front and rear pressure rollers 21 and 2 extrude and clamp the water-absorbing yarn 5, and the rotation speed of the rear pressure roller 2 is greater than that of the front pressure roller 21;

[0049] The front and rear pressure rollers 21 and 2 have the same structure, the rear pressure roller 2 comprises a fixed roller 23 and a movable roller 24, the fixed roller 23 is rotatably installed on the side wall of the processing groove, a motor 22 is installed on the side surface of the base 1, the motor 22 drives the fixed roller 23 to rotate through a transmission belt, an installation groove is formed in the side wall of the processing groove, the movable roller 24 is rotatably installed on a sliding block 241, the sliding block 241 is slidably installed in the installation groove, elastic blocks 242 are installed on the upper and lower surfaces of the sliding block 241, the elastic blocks 242 contact the bottom and top surfaces of the installation groove, a screw rod 243 is installed in the installation groove, a connecting plate 244 is rotatably installed at the lower end of the screw rod 243, and the connecting plate 244 and the upper surface of the sliding block 241 are in contact with each other;

[0050] When the hydrophilic finishing is performed, the water-absorbing yarn 5 enters and exits the treatment tank from the contact roller 11 on the treatment device, and meanwhile, the movement direction of the water-absorbing yarn 5 in the treatment tank is changed by the multiple sets of guide rollers 12 installed in the treatment tank, so that the water-absorbing yarn 5 passes through the hydrophilic finishing agent, and the hydrophilic finishing of the water-absorbing yarn 5 is completed. In this process, the front pressing roller 21 and the rear pressing roller 2 at both ends of the treatment tank press and clamp the water-absorbing yarn 5, so as to ensure that the water-absorbing yarn 5 is in a taut state and does not slide relatively in the treatment tank. Meanwhile, the rear pressing roller 2 is relatively large in rotating speed, and exerts a pulling force on the water-absorbing yarn 5, so that the water-absorbing yarn 5 is straightened and stretched, promotes the broken-down of viscose fibers in the water-absorbing yarn 5 after swelling due to water absorption, and at the same time, when the water-absorbing yarn 5 passes through the hydrophilic finishing agent and reaches the rear pressing roller 2, the rear pressing roller 2 presses and compacts the water-absorbing yarn 5, so that the excessive hydrophilic finishing agent absorbed on the water-absorbing yarn 5 is squeezed out and separated, thereby avoiding waste of the hydrophilic finishing agent and pollution caused by the hydrophilic finishing agent leaving with the water-absorbing yarn 5.

[0051] As an embodiment of the present application, a loosening cylinder 4 is installed in the treatment tank, the loosening cylinder 4 is located between the front pressing roller 21 and the guide roller 12, the water-absorbing yarn 5 passes through the loosening cylinder 4, and brush hairs 41 are installed on the inner wall of the loosening cylinder 4, which card and scratch the water-absorbing yarn 5;

[0052] After the water-absorbing yarn 5 passes through the front pressing roller 21, the water-absorbing yarn 5 is pressed and compacted, so that it becomes relatively dense and is not easy for the subsequent hydrophilic finishing agent to penetrate, which affects the hydrophilic finishing effect of the water-absorbing yarn 5. Therefore, after the water-absorbing yarn 5 passes through the front pressing roller 21, it enters the inside of the loosening cylinder 4, and the brush hairs 41 installed on the inner wall of the loosening cylinder 4 card and scratch the water-absorbing yarn 5, so that the water-absorbing yarn 5 becomes relatively loose and fluffy again, which is beneficial for the subsequent penetration of the hydrophilic finishing agent into the water-absorbing yarn 5, speeds up the treatment time and improves the hydrophilic finishing effect. Meanwhile, after the brush hairs 41 card and scratch the water-absorbing yarn 5, the broken ends of the fibers on the surface of the water-absorbing yarn 5 are scraped up, so that the surface of the water-absorbing yarn 5 appears to be “sanded”, so that after the water-absorbing yarn 5 enters the hydrophilic finishing agent, it quickly absorbs the hydrophilic finishing agent, promotes the penetration of the hydrophilic finishing agent into the water-absorbing fibers, and improves the finishing effect.

[0053] As an embodiment of the present application, the brush hairs 41 in the loosening cylinder 4 are distributed in a spiral shape, and the center line of the inner wall of the loosening cylinder 4 is curved.

[0054] The bristles 41 inside the loose cylinder 4 are distributed in a spiral shape, so that the surface of the water-absorbing yarn 5 passing through the inside of the loose cylinder 4 can be contacted by the bristles 41, avoiding dead angles, and avoiding the mutual contact, winding and interlacing between the bristles 41 after the bristles 41 are driven by the water-absorbing yarn 5, which affects the carding and scraping effect of the water-absorbing yarn 5. At the same time, due to the spiral distribution of the bristles 41 and the bending of the center line of the loose cylinder 4, the water-absorbing yarn 5 and the bristles 41 inside the loose cylinder 4 can be further fully contacted, the carding and scraping effect of the bristles 41 on the water-absorbing yarn 5 is improved, and the water-absorbing yarn 5 is ensured to become relatively loose again.

[0055] As an embodiment of the present application, a treatment cylinder 3 is installed in the treatment tank, the treatment cylinder 3 is located between the guide rollers 12, and the water-absorbing yarn 5 passes through the inside of the treatment cylinder 3.

[0056] A liquid pump 31 is installed on the side of the base 1, the liquid pump 31 pumps the hydrophilic finishing agent in the treatment tank into the treatment cylinder 3, a cavity 32 is formed in the side wall of the treatment cylinder 3, a spray hole 321 is formed in the inner wall of the treatment cylinder 3 and communicates with the cavity 32, and the liquid pump 31 sends the pumped liquid into the cavity 32 through a pipeline 311.

[0057] When the water-absorbing yarn 5 passes through the inside of the treatment cylinder 3, the liquid pump 31 installed on the base 1 pumps and delivers the hydrophilic finishing agent in the treatment tank into the cavity 32 in the side wall of the treatment cylinder 3, so that the hydrophilic finishing agent is sprayed from the spray hole 321 towards the water-absorbing yarn 5, so that the water-absorbing yarn 5 is fully contacted with the hydrophilic finishing agent, and under the flow impact of the hydrophilic finishing agent, the absorption of the water-absorbing yarn 5 to the hydrophilic finishing agent is promoted, so that the hydrophilic finishing agent penetrates into the water-absorbing yarn 5, the speed and effect of the hydrophilic finishing are improved, and at the same time, the pumping of the liquid pump 31 and the spraying of the hydrophilic finishing agent from both ends of the treatment cylinder 3 make the hydrophilic finishing agent in the treatment tank flow, so as to ensure that the concentration of the hydrophilic finishing agent in the treatment tank is uniform, and the water-absorbing yarn 5 avoids contacting the area with low concentration of the hydrophilic finishing agent, which affects the finishing effect of the water-absorbing yarn 5.

[0058] As an embodiment of the present application, a sponge sheet 33 is installed in the treatment cylinder 3, and the sponge sheet 33 divides the space in the treatment cylinder 3 into multiple spaces.

[0059] The outlet direction of the spray hole 321 is inclined along the axial direction, the spray holes 321 are arranged in pairs in the treatment cylinder 3, and the inclined directions of the spray holes 321 arranged in pairs are opposite.

[0060] The sponge sheet 33 is installed in the processing cylinder 3, and when the water-absorbing yarn 5 passes through the sponge sheet 33, the sponge sheet 33 can produce kneading and extrusion effects on the water-absorbing yarn 5, promote the fluffing of the water-absorbing yarn 5 and the absorption of the hydrophilic finishing agent, and at the same time, the installed multiple groups of sponge sheets 33 can separate the space in the processing cylinder 3 to some extent, hinder the hydrophilic finishing agent in the processing cylinder 3 from being discharged outward, so that the pressure in the processing cylinder 3 is greater than the pressure in the processing tank, and the relatively large pressure is used to promote the penetration of the hydrophilic finishing agent into the water-absorbing yarn 5, improve the speed and effect of hydrophilic finishing, and at the same time, the sponge sheet 33 is used to block the discharge of the hydrophilic finishing agent in the processing cylinder 3, so as to avoid the speed of the discharged hydrophilic finishing agent in the processing cylinder 3 being too fast, causing large fluctuations or splashes in the processing tank, and causing the hydrophilic finishing agent to splash out, causing waste and pollution, and at the same time, the pair of oppositely inclined spray holes 321 are arranged, so that the hydrophilic finishing agent sprayed from the spray hole 321 can be aimed at and impacted on the water-absorbing yarn 5, so that the water-absorbing yarn 5 is impacted and vibrates, further promoting the penetration of the hydrophilic finishing agent into the water-absorbing yarn 5 and the breaking of the viscose fibers in the water-absorbing yarn 5 from the notch.

[0061] The specific working process is as follows:

[0062] The cotton fiber is used to improve the hydrophilicity of the water-absorbing yarn 5, and the cloth made of the water-absorbing yarn 5 can quickly absorb water and promote surface drying after being made into a school uniform; the polyester fiber is used to improve the strength of the water-absorbing yarn 5 after blending;

[0063] Because the shrinkage rate of viscose fiber is greater than that of cotton fiber and polyester fiber, when the water-absorbing yarn 5 is pressed at both ends and tightened during hydrophilic finishing, the viscose fiber is broken at the notch, causing the viscose fiber to shrink, thereby forming a notch or protruding point on the surface of the water-absorbing yarn 5, and further increasing the gap between the cloth and the skin of the wearer after the water-absorbing yarn 5 is made into cloth and the cloth is made into a school uniform, which is conducive to ventilation and quick drying after sweating, and the shrunk viscose fiber also increases the gap between the water-absorbing yarn 5 of the cloth, thereby increasing the porosity of the cloth;

[0064] By changing the size of the warp and weft density, the density of the surface fabric of the double-layer fabric is greater than that of the inner layer fabric, so that the porosity of the inner layer fabric is relatively large after the fabric is made into a school uniform, which is conducive to the absorption of sweat by the fabric, and because the amount of cotton fiber contained in the surface fabric is greater than that of the inner layer fabric, the sweat absorbed by the inner layer fabric is more easily sucked to the surface fabric and evaporated.

[0065] The number of cotton fibers in the water-absorbing yarn 5 is relatively large, and the water-absorbing yarn 5 is subjected to hydrophilic finishing, so as to improve the water absorption of the cloth made of the water-absorbing yarn 5, and make the absorbed water quickly transferred to the surface of the cloth and evaporated, thereby making the water absorption and quick drying effect of the cloth good;

[0066] When the hydrophilic finishing is performed, the water-absorbing yarn 5 enters and exits the treatment tank from the contact roller 11 on the treatment device, and at the same time, the movement direction of the water-absorbing yarn 5 in the treatment tank is changed by the multiple sets of guide rollers 12 installed in the treatment tank, so that the water-absorbing yarn 5 passes through the hydrophilic finishing agent, and the hydrophilic finishing of the water-absorbing yarn 5 is completed. In this process, the front pressure roller 21 and the rear pressure roller 2 at both ends of the treatment tank press and clamp the water-absorbing yarn 5 to ensure that the water-absorbing yarn 5 is in a taut state and does not slide relatively in the treatment tank. At the same time, the rear pressure roller 2 rotates at a relatively high speed to apply tension to the water-absorbing yarn 5, so that the water-absorbing yarn 5 is straightened and stretched, promoting the viscose fibers in the water-absorbing yarn 5 to break off from the broken groove after swelling due to water absorption. At the same time, when the water-absorbing yarn 5 passes out of the hydrophilic finishing agent and reaches the rear pressure roller 2, the rear pressure roller 2 presses and compacts the water-absorbing yarn 5, so that the excess hydrophilic finishing agent absorbed on the water-absorbing yarn 5 is squeezed out and separated;

[0067] After the water-absorbing yarn 5 passes out of the front pressure roller 21, the water-absorbing yarn 5 is pressed and compacted, which makes it relatively dense and not easy for the subsequent hydrophilic finishing agent to penetrate, which will affect the hydrophilic finishing effect of the water-absorbing yarn 5. Therefore, after the water-absorbing yarn 5 passes out of the front pressure roller 21, it enters the inside of the loosening cylinder 4, and the bristles 41 installed on the inner wall of the loosening cylinder 4 comb and scratch the water-absorbing yarn 5, so that the water-absorbing yarn 5 becomes relatively loose and fluffy again. At the same time, after the bristles 41 comb and scratch the water-absorbing yarn 5, the fiber ends on the surface of the water-absorbing yarn 5 are scraped up, so that the water-absorbing yarn 5 has a "sanding" effect on the surface;

[0068] The bristles 41 inside the loosening cylinder 4 are distributed in a spiral shape, so that the water-absorbing yarn 5 passing through the inside of the loosening cylinder 4 can contact the bristles 41 everywhere on its surface. At the same time, due to the spiral distribution of the bristles 41 and the bending of the center line of the loosening cylinder 4, the water-absorbing yarn 5 and the bristles 41 inside the loosening cylinder 4 are in further full contact;

[0069] When the water-absorbing yarn 5 passes through the treatment cylinder 3, the liquid pump 31 installed on the base 1 sucks and transports the hydrophilic finishing agent in the treatment tank to the cavity 32 in the side wall of the treatment cylinder 3 through the pipeline 311, so that the hydrophilic finishing agent is sprayed out of the water-absorbing yarn 5 from the spray hole 321, so that the water-absorbing yarn 5 fully contacts the hydrophilic finishing agent. At the same time, through the extraction of the liquid pump 31 and the spraying of the hydrophilic finishing agent from both ends of the treatment cylinder 3, the hydrophilic finishing agent in the treatment tank will flow in a cycle;

[0070] The sponge sheet 33 is installed in the processing cylinder 3, when the water-absorbing yarn 5 passes through the sponge sheet 33, the sponge sheet 33 will produce kneading and extrusion effect on the water-absorbing yarn 5, promote the water-absorbing yarn 5 to be fluffy and absorb the hydrophilic finishing agent, at the same time, the installed multiple groups of sponge sheets 33 will separate the space in the processing cylinder 3, hinder the hydrophilic finishing agent in the processing cylinder 3 to be discharged outward, so that the pressure in the processing cylinder 3 is greater than the pressure in the processing tank, the relatively large pressure is used to promote the hydrophilic finishing agent to penetrate into the water-absorbing yarn 5, at the same time, through the pair of oppositely inclined spray holes 321, the hydrophilic finishing agent sprayed in the spray hole 321 will be aimed at and impact the water-absorbing yarn 5, the water-absorbing yarn 5 is impacted to vibrate, further promote the hydrophilic finishing agent to penetrate and promote the viscose fiber in the water-absorbing yarn 5 to be broken from the broken groove.

Those skilled in the art should understand that the present application is not limited by the above examples, the above examples and the description in the specification are only to illustrate the principles of the present application, various changes and improvements can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
