Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and particularly relates to sweat-free breathable cotton and its processing method. Background Art

[0002] With the continuous development of science and technology, textile fabrics that meet different needs of people emerge in an endless stream to meet the needs of consumers and play an increasingly important role in people's daily lives. Most of the fabrics currently available on the market only have some comfort function characteristics, and the effects are relatively single, unable to meet the wide range of usage requirements of users.

[0003] For example, existing rainproof fabrics mostly have a waterproof coating applied on the fabric surface. However, such waterproof coatings greatly reduce the moisture absorption and breathability of the fabric, resulting in discomfort for users when wearing and greatly reducing the usage requirements of users. Summary of the Invention

[0004] The purpose of the present invention is to solve the above-mentioned technical problems existing in the prior art, and provide sweat-free breathable cotton and its processing method, which can achieve two completely opposite composite functions on the same fabric, that is, the outer layer is water-repellent and the inner layer is moisture-absorbing and breathable, and does not affect the appearance, feel and breathability of the fabric, meeting the wide range of usage requirements of users.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] Sweat-free breathable cotton, characterized in that: it includes a hydrophilic layer, a buffer layer and a waterproof layer, with the waterproof layer as the outer layer and the hydrophilic layer as the inner layer. The hydrophilic layer includes super-matt regenerated polyester and a moisture-absorbing and sweat-releasing finishing agent, and the waterproof layer includes pure cotton yarn and a bio-based waterproof agent.

[0007] A processing method for sweat-free breathable cotton, characterized by including the following steps:

[0008] a. Obtain a grey fabric:

[0009] (1) Preparation of front water-repellent yarn: Select 30-60S / 1 pure cotton yarn, subject the yarn to a water bath, control the bath ratio of the yarn to water to be 1:10-20, add 10-15% o.w.f of a bio-based waterproof agent to the water through a pump, control the pump speed at 60-70%, spray the material on the pure cotton yarn, then raise the temperature to a set temperature A, keep it warm, and finally lower the temperature to a set temperature B for drainage.

[0010] (2) Use matt polyester for the middle connecting line and dye the yarn.

[0011] (3) Preparation of the reverse hydrophilic yarn: Select 50D - 75D super dull recycled polyester. This super dull recycled polyester is a profiled-section polyester. Subject this yarn to a water bath, add dyes and moisture management finishing agents to the water, then raise the temperature to the set temperature C, keep it warm, and finally lower the temperature to the set temperature D and drain the water.

[0012] (4) Weave the pure cotton yarn, the intermediate connecting yarn, and the reverse hydrophilic yarn to process and obtain a greige fabric.

[0013] b. Bake and crosslink the greige fabric: Immerse the greige fabric in 50°C warm water in a stenter, control the liquor pickup rate of the fabric to be 80 - 90%, and then control the setting temperature and speed of the stenter to bake and crosslink the fabric.

[0014] c. Singe the front side of the pre-treated greige fabric to remove the fuzz.

[0015] d. Degrease and wash the singed fabric.

[0016] e. Dehydrate, open-width, and dry the fabric in sequence.

[0017] f. Fabric setting treatment: Prepare a setting finishing solution with a polyester hydrophilic softener, then immerse the fabric in the setting finishing solution, control the liquor pickup rate of the fabric to be 80 - 90%, and then control the setting temperature and speed of the stenter to set the fabric.

[0018] Furthermore, in step a (1), the set temperature A is 80°C, at the same time control the heating rate to be 2°C / min, the holding time is controlled within 20 - 30 min, the set temperature B is 70°C, and control the cooling rate to be 1°C / min.

[0019] Furthermore, the rotation direction of the pump is 2 circles forward and 3 circles backward.

[0020] Furthermore, in step a (3), the set temperature C is 130 - 135°C, at the same time control the heating rate to be 2°C / min, the holding time is controlled within 20 - 30 min, the set temperature D is 70°C, and control the cooling rate to be 1°C / min.

[0021] Furthermore, in step b, control the setting temperature of the stenter to be 170 - 180°C and the speed to be 18 - 20 m / min. In step f, control the setting temperature of the stenter to be 140 - 160°C and the speed to be 18 - 22 m / min.

[0022] Furthermore, in step a, suspend the bobbins in the dyeing machine through a dyeing rack and spray materials on the front water-repellent yarn.

[0023] The dyeing rack includes a yarn reel, a suspension rod, and a yarn rod. The yarn reel is connected to the central seat of the dyeing machine. A backing plate is provided at the bottom of the yarn rod, and the backing plate is fixed in the water outlet hole of the yarn reel. A cavity is provided inside the yarn rod, and permeation holes are provided on the surface of the yarn rod. The water outlet hole, the permeation holes, and the cavity are connected. The suspension rod is installed at the central position of the yarn reel.

[0024] Specifically, it includes the following steps:

[0025] (1) Install the bobbins onto the yarn rod: Install the bobbins onto the yarn rod one by one. The bobbins are distributed vertically. The lowermost bobbin is supported on the backing plate. Then, put the connection hole of the sealing plate over the yarn rod, use the sealing plate to press the uppermost bobbin, and then use the locking structure to limit the sealing plate on the yarn rod.

[0026] (2) Install a positioning rod and a lifting device on the yarn reel. The positioning rod is provided with a positioning hole, and the lifting rod of the lifting device is provided with Magnet I.

[0027] (3) Install the diversion plate onto the lifting device: The selected diversion plate is provided with a connected notch and through-hole. The position of the through-hole is determined according to the distribution position of the bobbins on the yarn reel. The diversion plate is provided with a first diversion slope and a second diversion slope. The first diversion slope is connected to the through-hole, and the second diversion slope is connected to the notch. Use a mechanical gripper to grasp the ear plate of the diversion plate, place the diversion plate from bottom to top. At this time, the bobbin passes through the through-hole, and the second magnet provided at the bottom of the diversion plate attracts and fixes with Magnet I. The rod body at the bottom of the diversion plate penetrates into the positioning hole of the positioning rod.

[0028] (4) Use a grasping structure to grasp the suspension rod, and place the dyeing rack into the dyeing machine, so that the infusion pipe of the dyeing machine is connected to the water outlet hole of the yarn reel.

[0029] (5) Use the infusion pipe to convey the bio-based waterproof agent and water under the action of a pump. The permeation holes of the yarn rod spray the material onto the yarn of the bobbin. At this time, turn on the lifting device, and the lifting rod controls the diversion plate to move up and down below the sealing plate. The liquid flows to the outside of the yarn of the bobbin again through the first diversion slope and the second diversion slope, and performs spraying treatment on the yarn.

[0030] Furthermore, the locking structure includes an insertion plate and a pipe sleeve. A connection head is provided at the top of the yarn rod. The connection head is provided with a limiting hole. Two clamping blocks are fixed to the connection head. The two clamping blocks form an opening. The clamping block is provided with a groove, and the groove communicates with the opening. The specific steps are as follows:

[0031] (1) Put the pipe sleeve over the connection head.

[0032] (2) The cross-sectional area of the used insertion plate gradually increases from bottom to top. Set the insertion plate from top to bottom into the opening and snap it into the groove. At this time, the limiting rod of the insertion plate is clamped in the limiting hole. The insertion plate causes the two clamping blocks to deform outward, and the deformed clamping blocks limit the pipe sleeve, and the pipe sleeve presses the sealing plate.

[0033] Further, after the waterproof treatment of the yarn is completed, the bobbins are collected, which specifically includes the following steps:

[0034] (1) Use a grasping structure to grasp the hanging rod, take out the dyeing rack from the dyeing machine, move it between the rotating brackets, and then turn the rotating part on the rotating bracket. The rotating part penetrates into the round hole of the connecting block of the yarn disc.

[0035] (2) Loosen the grasping structure, then rotate the yarn disc 180° on the rotating part, and then turn the fixing rod on the fixing plate inside the rotating bracket. The fixing rod extends into the positioning hole of the positioning rod. At this time, the yarn rod of the yarn disc is set downward.

[0036] (3) Separate each yarn rod of the yarn disc into bobbins individually. First, hold the sealing plate, then remove the insertion plate and the tube sleeve of the locking structure, and the clamping block returns to its original state. Then place a material cylinder under the single yarn rod. The material cylinder has a cavity, and a central rod is provided at the center position of the cavity of the material cylinder. A magnet III is provided at the top of the central rod, and the magnet III is aligned with and attracted to the clamping block. Loosen the sealing plate, and the sealing plate and the bobbins distributed up and down as a whole slide down from the yarn rod into the cavity of the material cylinder. Then remove the material cylinder, and then set an end cap on the top of the material cylinder. The plug of the end cap is embedded into the cavity and presses the uppermost bobbin. At the same time, the central rod penetrates into the central hole of the plug. Using the above steps, collect the bobbins of all the yarn rods of the yarn disc.

[0037] (4) Move two adjacent material cylinders closer so that the plate body I at the bottom of the material cylinders overlaps each other and is fixedly connected by bolts, and the plate body II of the end caps overlaps each other and is fixedly connected by bolts.

[0038] Further, use a circular knitting machine to weave pure cotton yarn, intermediate connecting yarn and reverse hydrophilic yarn. The circular knitting machine is equipped with a triangular seat, a top block, a moving plate and knitting needles. The triangular seat is provided with a sliding groove. The top block is fixed on the moving plate. The moving plate is provided with a slider, and the slider moves up and down directionally in the sliding groove. Two adjusting parts are fixed on the triangular seat. The moving plate is arranged between the two adjusting parts. The adjusting part includes a mounting plate and a limiting head. The limiting head is threadedly connected to the mounting plate. A reset device is fixed on the triangular seat. The reset device includes a reset base and a movable rod. The movable rod moves up and down in the hole of the reset base, and a spring is provided between the movable rod and the reset base.

[0039] The top block is triangular, the apex angle of the top block is an obtuse angle, the inclination angle of the first hypotenuse of the top block is less than the inclination angle of the second hypotenuse of the top block. A notch is provided at the bottom of the top block, and the notch corresponds to the apex angle of the top block. A needle running groove is formed between two top blocks distributed up and down. The needle butt of the knitting needle is arranged in the needle running groove and moves along the first hypotenuse and the second hypotenuse.

[0040] Specifically, it includes the following steps:

[0041] (1) Install the knitting needles into the circular knitting machine.

[0042] (2) Unscrew the limit head. Under the elastic action of the spring, the movable rod moves upward in the hole of the reset base. The movable rod acts on the slider of the moving plate, causing the moving plate to move upward and return the moving plate to its initial position.

[0043] (3) According to the position of the needle cam on the knitting needle, screw in the upper limit head. The upper limit head acts on the top surface of the slider of the moving plate, causing the moving plate to move downward and compressing the spring. Align the needle cam and the needle groove of the knitting needle, and then screw in the lower limit head. The lower limit head acts on the bottom surface of the slider of the moving plate, fixing the moving plate on the triangular seat.

[0044] (4) Control the knitting needles to enter the needle grooves through the circular knitting machine. The needle cams on the knitting needles move upward along the first hypotenuse. After passing through the apex angle of the top block, the needle cams on the knitting needles then move downward along the second hypotenuse to perform knitting on the pure cotton yarn, the intermediate connecting line, and the reverse hydrophilic yarn.

[0045] Due to the adoption of the above technical solutions, the present invention has the following beneficial effects:

[0046] 1. The present invention can achieve two completely opposite composite functions on the same piece of fabric: the outer layer is water-repellent, preventing sweat from penetrating to the outer layer and not showing sweat stains. At the same time, the waterproof layer does not affect the air permeability of the fabric, ensuring elegant and comfortable wearing. The moisture brought by sweating will be quickly absorbed by the inner layer of the fabric, and the sweat will quickly spread in the inner layer, effectively preventing the accumulation of moisture. The increased spreading area of sweat in the inner layer of the fabric allows it to quickly volatilize and dry.

[0047] The outer layer of the present invention is water-repellent, and the inner layer is moisture-absorbing and breathable, without affecting the appearance, feel, and air permeability of the fabric, meeting the wide range of usage requirements of users.

[0048] 2. The present invention can make the waterproof effects on the inner and outer sides of the yarn of the bobbin uniform, improving the waterproof effect of the waterproof layer.

[0049] 3. It is convenient to collect the bobbins as a whole, protecting the yarn of the bobbins. At the same time, when taking out the bobbins, there is no need to grasp them, avoiding damage to the yarn of the bobbins. Moreover, the bobbins on the same dyeing rack can be collected side by side, facilitating the classification and transportation of the bobbins and facilitating the subsequent knitting work.

[0050] 4. In this operation, by lifting the knitting needles, the output of yarn weaving can be increased. Since the inclination angle of the second hypotenuse is greater than that of the first hypotenuse, the yarn lifting angle is large, making the woven fabric tighter. Moreover, considering that the needle - passing positions of different yarns are different, according to the installation positions of the knitting needles, the present invention adjusts the installation position of the moving plate up and down through two adjusting parts to change the position of the top block, and then adjusts the position of the needle - passing groove according to the needle cams on the knitting needles, so that the needle cams and the needle - passing grooves of the knitting needles are correspondingly arranged, improving the stability and accuracy of the movement of the knitting needles and the quality of weaving.

Detailed implementation manners

[0085] Example 1

[0086] As Figure 32 shown, it is the sweat-free breathable cotton of the present invention, specifically including a hydrophilic layer c, a buffer layer b and a waterproof layer a. The buffer layer b separates the hydrophilic layer c and the waterproof layer a, so that the hydrophilic layer c and the waterproof layer a do not interfere with each other. The waterproof layer a is used as the outer layer, and the hydrophilic layer c is used as the inner layer. The hydrophilic layer c includes super dull regenerated polyester and a moisture absorption and sweat discharge finishing agent, and the waterproof layer a includes pure cotton yarn and a bio-based waterproof agent.

[0087] The processing method of the sweat-free breathable cotton includes the following steps:

[0088] a. Obtain a greige fabric:

[0089] (1) Preparation of the front water-repellent yarn: Select 40S / 1 pure cotton yarn, subject the yarn to a water bath, control the bath ratio of the yarn to water to be 1:10, add 10% o.w.f of a bio-based waterproofing agent to the water, pump the liquid, control the pump speed to be 60%, and the pump rotation direction to be 2 circles forward and 3 circles backward, which can prevent the bio-based waterproofing agent from coagulating and blocking the pipe. Then spray the material on the pure cotton yarn to make the bio-based waterproofing agent uniformly penetrate. Then raise the temperature to 80 °C, while controlling the heating rate to be 2 °C / min, keep warm for 30 min, then lower the temperature to 70 °C, control the cooling rate to be 1 °C / min, and then drain the water.

[0090] (2) The middle connecting line is a buffer layer, which has the function of separating the hydrophilic layer c and the waterproof layer a. Specifically, dull polyester is used and the yarn is conventionally dyed.

[0091] (3) Preparation of the back hydrophilic yarn: Select 75D super-dull regenerated polyester, and this super-dull regenerated polyester is profiled-section polyester. Subject the yarn to a water bath, control the bath ratio of the yarn to water to be 1:10. Add dyes and a moisture absorption and sweat discharge finishing agent 1% o.w.f to the water, then raise the temperature to 135 °C, while controlling the heating rate to be 2 °C / min, keep warm for 20 min, and finally lower the temperature to 70 °C, control the cooling rate to be 1 °C / min, and then drain the water.

[0092] (4) Weave the pure cotton yarn, the middle connecting line and the back hydrophilic yarn to process and obtain a greige fabric.

[0093] b. Bake and crosslink the greige fabric: Immerse the greige fabric in 50 °C warm water on a stenter, control the liquor pickup rate of the fabric to be 80 - 90%, then control the setting temperature of the stenter to be 170 °C and the vehicle speed to be 18 m / min to bake and crosslink the fabric.

[0094] c. Singe the front side of the pre-treated greige fabric to remove the hairiness and improve the anti-pilling property.

[0095] d. De-oil and wash the singed fabric.

[0096] e. Dehydrate, open-width and dry the fabric in sequence.

[0097] f. Fabric setting treatment: Prepare a setting finishing solution with a polyester hydrophilic softener, then immerse the fabric in the setting finishing solution, control the liquor pickup rate of the fabric to be 80%, then control the setting temperature of the stenter to be 140 °C and the vehicle speed to be 18 m / min to set the fabric.

[0098] The outer layer is tested and evaluated for waterproof performance according to GB / T 4745-2012 Textiles, and the test method of the water-spraying method is used. The product finally meets the water-spraying grade ≥ 3 - 4 levels, achieving a good water-repellent effect, while preventing sweat stains from penetrating into the outer layer and having the function of preventing sweat stains.

[0099] The inner layer complies with the test method in Part 2: Dynamic Moisture Transfer Method of GB / T 21655.2-2019 Textiles - Evaluation of Moisture Absorption and Quick Drying Properties. The product finally meets the following requirements:

[0100] Wetting time T / s: ≤3s, Grade 5.

[0101] Water absorption rate A / (% / s): ≥50% / s, ≥Grade 4.

[0102] Maximum wetting radius: ≥17.1mm, ≥Grade 4.

[0103] Liquid water diffusion rate: ≥3.1mm / s, ≥Grade 4.

[0104] The bio-based waterproofing agent, moisture absorption and sweat discharge finishing agent, and polyester hydrophilic softening agent of the present invention are specifically selected as follows:

[0105] Bio-based waterproofing agent: BAYGARD LTR 01 produced by Tana Shanghai Tana Chemical New Materials Co., Ltd. It is a durable waterproofing agent made from plant waste (such as coconut meat), containing more than 60% biochar, and is used for waterproof treatment of fabrics or yarns by impregnation method, endowing fabrics or yarns with excellent waterproof effects.

[0106] Moisture absorption and sweat discharge finishing agent: FERAN ICC produced by Rudolf Chemical (Dongguan) Co., Ltd. It is a non-ionic carboxylic acid ethoxylate compound, which can be used for hydrophilic finishing of polyester fabrics or yarns, endowing polyester fabrics or yarns with good hydrophilicity and moisture absorption.

[0107] Polyester hydrophilic softening agent: ULTRAPHIL TG-01 produced by Huntsman Textile Effects (China) Co., Ltd. It is a non-ionic hydrophilic polymer dispersion liquid with unique hydrophilic effects, especially suitable for fabrics with waterproof front and hydrophilic back in the present invention. While improving the fabric handle, it enhances the hydrophilic effect of the backside polyester and does not affect the waterproof effect of the front side.

[0108] Example Two

[0109] As Figures 1 to 23 shown, based on the solution of the above Example One, the present invention specifically designs the spraying treatment for the water-repellent yarn on the front side.

[0110] In the prior art, the yarn bobbin is sleeved on the yarn rod, and the spraying material is applied to the yarn through the penetration holes of the yarn rod. Specifically refer to the invention patent of the dyeing rack for knitting and weaving yarns, zippers, ropes, tapes, and loose fibers (authorized announcement number: CN103132264B) in the comparative document.

[0111] However, the inner side of the cheese yarn contacts the yarn rod, and the outer side of the cheese yarn is at a certain distance from the yarn rod. The spraying material can fully contact the inner side of the cheese yarn. During the liquid penetration process, the penetration on the outer side of the cheese yarn is uneven, resulting in uneven waterproofing of the cheese yarn and affecting the waterproof performance of the outer layer of the fabric.

[0112] To solve the above technical problems, the dyeing rack of the present invention includes a yarn disc 1, a hanging rod 16, and a yarn rod 2. The yarn disc 1 is connected to the central seat of the dyeing machine. A backing plate 4 is provided at the bottom of the yarn rod 2, and the backing plate 4 is fixed in the water outlet hole 15 of the yarn disc 1. A cavity 14 is provided inside the yarn rod 2, and penetration holes 3 are provided on the surface of the yarn rod 2. The water outlet hole 15, the penetration holes 3, and the cavity 14 are connected. The water outlet hole 15 at the bottom of the yarn disc 1 is connected to a pump through an infusion tube. The hanging rod 16 is installed at the central position of the yarn disc 1. Specifically, a threaded head 17 is provided at the bottom of the hanging rod 16, a counterbore 19 is provided at the central position of the yarn disc 1, the threaded head 17 passes through the counterbore 19, and the threaded head 17 is threadedly connected to a nut 18. The nut 18 is arranged in the counterbore 19, which facilitates the replacement of the hanging rod 16 and at the same time avoids the influence of the threaded head 17 and the nut 18 on the installation of the yarn disc 1.

[0113] The spraying treatment of the front water-repellent yarn specifically includes the following steps:

[0114] (1) Install the cheese 20 onto the yarn rod 2: Slide the cheeses 20 onto the yarn rod 2 one by one. The cheeses 20 are distributed vertically, and the lowermost cheese 20 is supported on the backing plate 4. Then, insert the connection hole 6 of the sealing plate 21 onto the yarn rod 2, use the sealing plate 21 to press the uppermost cheese 20, and then use a locking structure to limit the sealing plate 21 on the yarn rod 2. A connection sleeve is provided at the top of the sealing plate 21, and anti-slip threads 24 are provided on the outer surface of the connection sleeve. The whole is sleeved on the yarn rod 2, which facilitates the installation of the sealing plate 21.

[0115] (2) Install the positioning rod 28 and the lifting device 26 on the yarn disc 1. The positioning rod 28 is provided with a positioning hole 29, and the lifting rod of the lifting device 26 is provided with a magnet 27. The lifting device 26 is fixed to the yarn disc 1 by bolts. The threaded column 30 at the bottom of the positioning rod 28 is threadedly connected to the threaded hole of the yarn disc 1, which facilitates the installation and disassembly of the positioning rod 28 and the lifting device 26.

[0116] (3) Install the flow guide plate 33 onto the lifting device 26: The selected flow guide plate 33 is provided with a communicating notch 37 and through hole 34. The notch 37 is used for liquid accumulation, and the position of the through hole 34 is determined according to the distribution position of the bobbins 20 on the yarn disc 1. The flow guide plate 33 is provided with a first flow guide slope 35 and a second flow guide slope 36. The first flow guide slope 35 is connected to the through hole 34, and the second flow guide slope 36 is connected to the notch 37. Use a mechanical gripper to grasp the ear plate 38 of the flow guide plate 33, and place the flow guide plate 33 from bottom to top. At this time, the bobbin 20 passes through the through hole 34, and the second magnet 40 provided at the bottom of the flow guide plate 33 attracts and fixes with the first magnet 27. The rod body 39 at the bottom of the flow guide plate 33 penetrates into the positioning hole 29 of the positioning rod 28. The flow guide plate 33 is detachably connected to the lifting device 26, which is convenient for removing the flow guide plate 33 and cleaning the flow guide plate 33.

[0117] (4) Use a grasping structure to grasp the hanging rod 16, and place the entire dyeing rack into the dyeing machine 41, so that the liquid delivery pipe of the dyeing machine 41 communicates with the water outlet hole 15 of the yarn disc 1. The liquid delivery pipe is connected to the material bucket through a pump, and a bio-based waterproof agent is added to the water in the material bucket. The grasping structure is a prior art. For specific reference, refer to the invention patent of a grabbing mechanism and operation method for discharging loose fibers in a dyeing tank for plant dyeing (application publication number: CN114892355A). In the specific design, the movable gripper and the fixed gripper can be replaced with a hook. In this way, a head 31 is provided at the top of the hanging rod 16 of the present invention, and a hanging hole 32 is provided at the head 31. The hook hooks the hanging hole 32 to lift and move the entire dyeing rack.

[0118] (5) Use the liquid delivery pipe to transport the bio-based waterproof agent and water. Under the action of the pump, the penetration holes 3 of the yarn rod 2 spray the material onto the yarn of the bobbin 20. The spraying process is a prior art. For specific reference, refer to the invention patent of a dyeing rack for loading needle and shuttle woven yarns, zippers, ropes, tapes, and loose fibers in a dyeing machine (authorization announcement number: CN103132264B) and the utility model patent of a spray jet type skein dyeing machine (authorization announcement number: CN2895482Y). At this time, turn on the lifting device 26. The lifting device 26 uses a hydraulic cylinder, and the lifting rod controls the flow guide plate 33 to move up and down below the sealing plate 21. The liquid flows to the outside of the yarn of the bobbin 20 again through the first flow guide slope 35 and the second flow guide slope 36 for spraying treatment of the yarn. The liquid penetrates to the outside through the yarn of the bobbin 20 and drops into the notch 37 of the flow guide plate 33. Under the up and down movement of the flow guide plate 33 and the guiding action of the two flow guide slopes, the liquid has good fluidity and uniform flow, so that the liquid is guided to the outside of the yarn of the bobbin 20. For the cylindrical yarn of the bobbin 20, the periphery of the outside of the yarn of the bobbin 20 can be acted on by the liquid of the flow guide plate 33, which can make the waterproof effects of the inner and outer sides of the yarn of the bobbin 20 uniform and improve the waterproof effect of the waterproof layer a. Moreover, the up and down movement of the flow guide plate 33 is stable, and the guiding function of the flow guide plate 33 is fully exerted.

[0119] In order to collect the bobbin 20 as a whole later, the present invention specifically designs the locking structure:

[0120] The locking structure includes an insert plate 23 and a sleeve 22. A connector 9 is provided on the top of the yarn rod 2. The connector 9 is provided with a limiting hole 13. Two clamping blocks 10 are fixed to the connector 9. The two clamping blocks 10 form an opening 12. The clamping blocks 10 are provided with a groove 11, and the groove 11 is connected to the opening 12.

[0121] The specific steps for installation are as follows:

[0122] (1) Put the mounting hole 5 of the pipe sleeve 22 onto the connector 9.

[0123] (2) The insert plate 23 is set from top to bottom into the opening 12 and inserted into the groove 11. The insert plate 23 can be pressed in by a cylinder. At this time, the limit rod 25 of the insert plate 23 is clamped in the limit hole 13, and the cross-sectional area of ​​the insert plate 23 gradually increases from bottom to top, so that the two clamping blocks 10 are deformed outward, and the deformed clamping blocks 10 limit the pipe sleeve 22, and the pipe sleeve 22 presses the sealing plate 21. When collecting the bobbins 20 at a later stage, it is only necessary to pull the insert plate 23 downward, so that the sealing plate 21 and the bobbins 20 distributed up and down can slide from the yarn rod 2 to the cavity of the barrel as a whole, and the bobbins 20 at a single yarn rod 2 can be quickly collected; and the locking and loosening method of the locking structure is to move the insert plate 23 up and down, without the need for rotation, which makes the installation and removal of the bobbins 20 more convenient.

[0124] If a robot is used to grab the bobbin 20, the yarn of the bobbin 20 is easily damaged, and the bobbin 20 is exposed and easy to accumulate dust. Therefore, after the yarn is waterproofed, the bobbin 20 is collected, which specifically includes the following steps:

[0125] (1) The lifting structure is used to grab the suspension rod 16, and the dyeing frame is taken out from the dyeing machine 41 and moved between the rotating brackets 42. Then, the rotating member 45 is screwed on the rotating bracket 42. The rotating member 45 and the rotating bracket 42 are threadedly connected, and the rotating member 45 is inserted into the circular hole 8 of the connecting block 7 of the yarn disc 1.

[0126] (2) Release the grabbing structure, rotate the yarn disc 1 180° on the rotating member 45, and then screw the fixing rod 44 on the fixing plate 43 on the inner side of the rotating bracket 42. The fixing rod 44 extends into the positioning hole 29 of the positioning rod 28. At this time, the yarn rod 2 of the yarn disc 1 is set downward, and the yarn disc 1 will not rotate, thereby improving the stability of taking out the bobbin.

[0127] (3) Remove each yarn rod 2 of the yarn bobbin 1 from the bobbin 20 separately. First, hold the sealing plate 21, and then remove the insertion plate 23 and the sleeve 22 of the locking structure. At this time, the clamping block 10 returns to its original state. Then, place the material cylinder 46 under the single yarn rod 2. The material cylinder 46 is provided with a cavity 49, and a central rod 47 is provided at the central position of the cavity 49 of the material cylinder 46. A magnet three 48 is provided at the top of the central rod 47, and the magnet three 48 is aligned with and attracted to the clamping block 10 to prevent the material cylinder 46 from tipping over. Loosen the sealing plate 21, and the sealing plate 21 and the bobbin 20 distributed up and down as a whole slide from the yarn rod 2 into the cavity 49 of the material cylinder 46. Then, remove the material cylinder 46, and then set an end cap 51 on the top of the material cylinder 46. The plug 52 of the end cap 51 is embedded into the cavity 49 and presses the uppermost bobbin 20. At the same time, the central rod 47 passes through the central hole 53 of the plug 52 to prevent the bobbin 20 from shaking in the material cylinder 46, and the end cap 51 and the material cylinder 46 are firmly connected. By using the above steps, the bobbins 20 of all the yarn rods 2 of the yarn bobbin 1 are collected.

[0128] (4) Bring two adjacent material cylinders 46 closer so that the plate body one 50 at the bottom of the material cylinder 46 overlaps each other and is fixedly connected by bolts, and the plate body two 54 of the end cap 51 overlaps each other and is fixedly connected by bolts.

[0129] In the process of taking out the bobbin 20 of the present invention, it falls into the interior of the material cylinder 46 by its own weight, without using a manipulator to grab, avoiding damage to the yarn of the bobbin 20. It is convenient to collect the bobbin 20 as a whole into the interior of the material cylinder 46. The hidden design of the bobbin 20 plays a protective role for the yarn of the bobbin 20. Moreover, the material cylinders 46 are connected side by side with each other, and the bobbins 20 on the same dyeing rack can be collected side by side, which is convenient for classifying and transporting the bobbins 20 and convenient for weaving work.

[0130] Embodiment III

[0131] As Figures 24 to 31 shown, on the basis of the solution of the above Embodiment I, a circular knitting machine 55 is used to weave pure cotton yarn, intermediate connecting yarn and reverse hydrophilic yarn, and the yarn needs to be tightly woven. The circular knitting machine 55 is equipped with a triangular seat 56, a top block 58, a moving plate 57 and knitting needles. The triangular seat 56 is provided with a chute 66. The top block 58 is fixed on the moving plate 57. The moving plate 57 is provided with a slider 70, and the slider 70 moves up and down directionally in the chute 66.

The movable rod 72 moves up and down in the hole of the reset base 71, and a spring 73 is arranged between the movable rod 72 and the reset base 71.

[0132] The top block 58 is triangular, the vertex angle 63 of the top block 58 is an obtuse angle, the inclination angle of the first hypotenuse 61 of the top block 58 is smaller than the inclination angle of the second hypotenuse 62 of the top block 58, a notch 65 is provided on the bottom edge 64 of the top block 58, the notch 65 is arranged corresponding to the vertex angle 63 of the top block 58, a needle running groove 59 is formed between two vertically distributed top blocks 58, and the needle cam of the knitting needle is arranged in the needle running groove 59 and moves along the first hypotenuse 61 and the second hypotenuse 62.

[0133] Specifically, it includes the following steps:

[0134] (1) Install the knitting needle 74 into the circular knitting machine 55, and the shape of the knitting needle 74 is different for different yarn selections.

[0135] (2) Unscrew the limit head 68, under the elastic action of the spring 73, the movable rod 72 moves upward in the hole of the reset base 71, the movable rod 72 acts on the slider 70 of the moving plate 57, so that the moving plate 57 moves upward and returns the moving plate 57 to the initial position.

[0136] (3) According to the position of the needle cam on the knitting needle 74, screw in the upper limit head 68, the upper limit head 68 acts on the top surface of the slider 70 of the moving plate 57, so that the moving plate 57 moves downward, the spring 73 is compressed, the needle cam of the knitting needle 74 is arranged corresponding to the needle running groove 59, and then screw in the lower limit head 68, the lower limit head 68 acts on the bottom surface of the slider 70 of the moving plate 57, so that the moving plate 57 is fixed on the triangular seat 56.

[0137] (4) Control the knitting needle 74 to enter the needle running groove 59 through the circular knitting machine 55, the needle cam on the knitting needle 74 moves upward along the first hypotenuse 61, after passing through the vertex angle 63 of the top block 58, then move the needle cam on the knitting needle 74 downward along the second hypotenuse 62 to carry out the weaving of the pure cotton yarn, the intermediate connecting line and the reverse hydrophilic yarn.

[0138] In this operation, by lifting the knitting needle 74, the output of yarn weaving can be increased. Since the inclination angle of the second hypotenuse 62 is greater than the inclination angle of the first hypotenuse 61, the yarn lifting angle is large, making the woven fabric tighter. Moreover, considering that the needle running positions of different yarns are different, according to the installation position of the knitting needle 74, the present invention adjusts the installation position of the moving plate 57 up and down through two adjusting parts 60, changes the position of the top block 58, and further adjusts the position of the needle running groove 59 according to the needle cam on the knitting needle 74, so that the needle cam of the knitting needle 74 is arranged corresponding to the needle running groove 59, improving the stability and accuracy of the movement of the knitting needle 74 and the quality of weaving.
