Description

Technical Field

[0001] The present application relates to the field of fabric preparation, and in particular to a manufacturing process of a single-parent and single-protective fabric. Background Art

[0002] With the rapid development of outdoor sports, functional clothing and other fields, the market demand for fabrics that are both waterproof and moisture-absorbing and quick-drying is increasing. Although traditional waterproof fabrics can effectively block the penetration of liquid water, their overall hydrophilicity is poor, which makes it difficult to quickly drain sweat and is not comfortable to wear; while moisture-absorbing and quick-drying fabrics have good moisture-conducting properties, they cannot effectively block external moisture penetration, and obvious water marks are easily formed on the fabric surface, affecting the appearance and practicality. To solve this problem, the industry has developed a single-sided hydrophilic and single-sided waterproof fabric design, that is, by combining one-sided waterproof with one-sided hydrophilic, a balance of waterproof and moisture-absorbing and quick-drying performance is achieved. This meets the dual needs of waterproofing and moisture absorption.

[0003] However, the single-sided hydrophilic and single-sided waterproof fabrics face the following technical problems during the preparation process: First, the amount of waterproofing agent added is difficult to accurately control. When too much waterproofing agent is added, it is easy to penetrate into the hydrophilic layer through capillary action, resulting in a significant decrease in the hydrophilic effect of the hydrophilic layer, an increase in the contact angle, and a deterioration in the moisture conductivity; when too little waterproofing agent is added, the waterproofing effect of the waterproof layer is insufficient, the contact angle decays faster, and it is difficult to achieve the expected waterproof level (such as level 4 or above in the ISO4920 standard). Secondly, the interfacial migration phenomenon of waterproofing agents (such as fluorine compounds) in the prior art is serious. After multiple washings, the waterproofing agent diffuses from the waterproof layer to the hydrophilic layer, resulting in the deterioration of the overall performance of the fabric, which is manifested in the decrease in waterproof level, weakened hydrophilic performance, and obvious water marks on the fabric surface. In addition, excessive use of waterproofing agents will also cause the fabric to feel hard, the free fluorine content exceeds the standard, and does not meet environmental protection standards, further limiting its scope of application.

[0004] Therefore, how to achieve precise control of waterproof and hydrophilic properties and ensure the durability and comfort of fabrics remains a key issue that needs to be urgently solved in the current technical field. Summary of the invention

They are relative concepts and may therefore change accordingly depending on their different positions and usage states.

In addition, the terms "first", "second", "third", etc. or similar expressions are only used for descriptive and differentiating purposes and cannot be understood as indicating or implying the relative importance of the corresponding components.

[0023] The following further elaborates on this application in conjunction with the attached Figure 1 and the attached Figure 2 to make a more detailed description of this application.

[0024] The embodiment of this application discloses a manufacturing process for a single-parent and single-proof fabric.

[0025] A manufacturing process for a single-parent and single-proof fabric, comprising the following steps: As Figure 1 , S1 Fabric substrate selection and structure design: A grey fabric with a weft plain stitch organizational structure is woven with 40S combed cotton yarn and 50D / 72F drawn textured yarn as the warp and weft; the weft plain stitch organization is also called plain stitch organization or single-sided plain stitch organization. Its characteristic is that all loops are formed in the same direction. The fabric formed by this knitting method has the following effects: 1. High elasticity and stretchability, and the prepared clothing can adapt to the dynamic activities of the body, providing better comfort and flexibility. 2. Durability: The loop-knitted fabric is more durable than other fabrics and can withstand frequent use and washing without being easily worn or faded. 3. Breathability: The loop-knitted fabric has good breathability and can effectively discharge sweat and moisture, keeping the body dry and comfortable. 4. Soft and comfortable: The loop-knitted fabric usually has a soft handfeel and good elasticity, making the fabric have a soft and comfortable handfeel and a good wearing experience.

[0026] As Figure 2 , the combed cotton yarn is cotton yarn, with a yarn length of 13.5CM / 50G; the drawn textured yarn is made of polyester, mainly polyester yarn, with a yarn length of 12.5CM / 50G. Through a circular knitting machine, the cotton yarn and the polyester yarn are together, with the cotton yarn on top and the polyester yarn at the bottom. Since the cotton yarn is thicker and the polyester yarn is thinner, when the circular knitting machine works, the cotton yarn can well cover and shield the polyester yarn, so that the front side of the grey fabric, that is, the outer layer of the grey fabric, is cotton, and the back side, that is, the inner layer of the grey fabric, is polyester.

[0027] In the grey fabric, the cotton proportion is 70%-75%; in this embodiment, it is preferably 75%; the cotton yarn has less hairiness and a faint luster on the surface, and the fabric feels smooth, soft and not stiff. The proportion of polyester is 25%-30%; in this embodiment, it is preferably 25%. The drawn textured yarn belongs to ultra-fine fiber, has a large specific surface area, good capillary effect and good moisture absorption effect, can quickly conduct the moisture and heat on the skin surface, keep the skin surface dry and cool, and has a good contact cold feeling effect. The fabric is thinner, and due to the porous chemical fiber, it has good moisture absorption, can quickly conduct the sweat from the inner layer to the outer layer and quickly dry through air circulation, making the fabric have the function of quick drying.

[0028] After the grey fabric is woven, the grey fabric is slit and rolled by a slitting machine.

[0029] The slitting machine includes a cylindrical grey fabric flattening system, a laser slitting unit, a stress elimination unit and a rolling system; among them, the cylindrical grey fabric flattening system is configured with multiple groups of fabric guiding rollers (Φ150-200mm), and an air-driven deviation correction device (accuracy ±1mm) is used to ensure the flatness of the fabric surface.

[0030] The laser slitting and coiling unit adopts a high-precision laser cutting head (wavelength 10.6μm, power 200 - 500W), and is equipped with a CCD vision positioning system (resolution 0.05mm).

[0031] The stress relief unit adopts a spiral width expanding roller (surface plated with hard chromium, roller diameter Φ250mm), and the axial expansion angle is adjustable from 15° to 25°.

[0032] The coiling system adopts constant tension control (adjustable from 5 - 15N) + taper adjustment function (3% - 8%), and is equipped with a surface coiling anti-wrinkle device.

[0033] Through slitting and coiling, the grey fabric can reduce crease defects, improve coiling efficiency and reduce energy consumption.

[0034] S2 Pre-setting of grey fabric: The grey fabric is put into a setting machine for setting. The setting temperature is 190℃ - 210℃, preferably 200℃ in this embodiment; the fabric speed is 45m / min - 55m / min, preferably 50m / min in this embodiment; under the process conditions of this pre-setting, the polyester yarn can achieve three effects through thermodynamic reorganization. 1. Molecular chain segment rearrangement: The macromolecular chains of polyester undergo relaxation movement under the action of high temperature, promoting the transformation of molecular chain segments in the amorphous region to an ordered state; 2. Crystallinity improvement: It is shown by differential scanning calorimetry (DSC) test that the crystallinity can be increased by 15% - 20% (ASTM D3418 standard); 3. Morphological structure optimization: Wide-angle X-ray diffraction (WAXD) shows that the diffraction peak intensity of the (110) crystal plane is significantly enhanced, and the integrity of the crystal region is improved. Through the above three effects, the following performance characteristics can be achieved: 1. Mechanical properties: The elastic modulus is increased by about 25% (tested according to GB / T 3923.1 - 2013); 2. Hand feeling characteristics: The bending stiffness is maintained at 2.5 - 3.5cN / cm² (ASTM D1388 standard), achieving a balance between softness and stiffness; 3. Dimensional stability: The thermal shrinkage rate is reduced to ≤2.5% (tested according to AATCC 135 - 2018). Finally, the grey fabric can be given a soft and somewhat stiff hand feeling.

[0035] S3 Dyeing of grey fabric: Dyeing is carried out through a dyeing agent. The dyeing machine adopts a cylindrical cylinder body, and the cylindrical cylinder body adopts a design without a fabric guiding roller, enabling the grey fabric to circulate and rotate in the cylinder; relying on the water flow and the spraying force of the nozzle to push the grey fabric to circulate, reducing the friction between the fabric and the fabric guiding roller, reducing the tension of the grey fabric, and avoiding the generation of creases. The softness of the grey fabric is improved. The ratio of dye to water is 1:6 to form dyeing water. The dyeing sequence of the grey fabric is: S31: Dyeing polyester; S32: Dyeing cotton. Because the dyes for polyester and cotton are different, they can be dyed successively.

[0036] In the polyester dyeing in step S31: A sulfonic acid group auxiliary agent is added during dyeing to make the inner layer of the polyester hydrophilic.

[0037] After the polyester dyeing in step S31, a bath reduction treatment is carried out. The main purposes of the bath reduction treatment are as follows: 1. Removing cotton impurities: The impurities such as cotton fibers or cottonseed hulls contained in the grey fabric can be decomposed and removed by the reducing agent in the bath; 2. Removing floating color: Removing the disperse dyes that have not entered the interior of the polyester fibers (i.e., floating color) to improve the color fastness and the cleanliness of the fabric surface; 3. Improving the color shade: Through the reduction treatment, the color development of the dye is made more pure, avoiding the color shade deviation caused by the floating color. It can also improve the hydrophilicity.

[0038] In step S31, a high-fastness macromolecular disperse dye is used; an oil remover W-245 and a leveling agent SN-7500 are added to the dyeing water and the temperature is set to 125°C - 135°C. In this embodiment, 130°C is preferably used, and the pH value of the dyeing water is between 4 and 4.5. The oil remover W-245 and the leveling agent SN-7500 in this application are prior arts and can be obtained in the market.

[0039] The steps for dyeing the polyester are as follows: First, add the oil remover W-245, the leveling agent SN-7500, and glacial acetic acid into the cylinder, mix them and let stand for 10 minutes. Then, detect the pH value. After the pH value meets the requirements, add the dye. The dye is slowly and continuously added for 20 minutes, and then the grey fabric is dyed for 10 minutes. Then, the temperature is raised at a rate of 3°C - 4°C per minute until 80°C, and the grey fabric is dyed at 80°C for 20 minutes; then, the temperature is raised to 110°C at a rate of 1.5°C per minute, and then the grey fabric is continuously dyed at 110°C for 20 minutes; then, the temperature is raised to 130°C at a rate of 1°C per minute, and then the grey fabric is continuously dyed at 130°C for 40 minutes; finally, the temperature is lowered at a rate of 2°C per minute until 60°C, and the polyester dyeing is completed. Then, the floating color of the polyester is washed. As Figure 3 FIG. is the process diagram of the polyester dyeing in S31.

[0040] Before the steps of dyeing the cotton, the cotton needs to be scoured first. First, keep the water temperature in the cylinder at 40°C, add the oil remover, oxygen bleaching stabilizer, penetrant, caustic soda, and the grey fabric, and stir them. Then, raise the temperature to 60°C, add hydrogen peroxide, then raise the temperature to 98°C and keep it for 40 minutes. Then, lower the temperature to 80°C at a rate of 2°C per minute, add sodium hydrosulfite, and keep the temperature at 80°C for 10 minutes. Then, raise the temperature to 90°C and keep it for 20 minutes. Finally, lower the temperature to 60°C and drain the water to obtain the scoured grey fabric. As Figure 4 FIG. is the process diagram of the cotton scouring.

[0041] After the cotton scouring, the cotton is dyed. In step S32, in the cotton dyeing, a high-sunlight-fastness dye is used; the high-sunlight-fastness dye is a prior art and can be obtained in the market.

[0042] The steps of cotton dyeing are as follows: Add the grey fabric into the dyeing vat, raise the water temperature to 50 °C and keep it for 20 minutes, then continuously add the dye. After the dye is continuously added for 20 minutes, keep it for 15 minutes. Then add soda ash. After soda ash is continuously added for 20 minutes, add caustic soda. After caustic soda is continuously added for 20 minutes, keep it for 5 minutes. Then raise the temperature to 60 °C at a rate of 1 °C per minute, and after keeping it for 75 minutes, the cotton dyeing is completed.

[0043] As Figure 5 is the process diagram of reactive soaping during the cotton dyeing process.

[0044] After the cotton dyeing is completed, reactive soaping is carried out at a temperature of 92 °C - 97 °C. In this embodiment, the temperature is preferably 95 °C. The time is 17 min - 23 min to clean the floating color.

[0045] S4 Stenter Squeezer: Immerse in clear water without adding additives, the temperature is 140 °C, and the fabric speed is 30 m / min; The stenter squeezer consists of the following structures: a trough body, a roller system, a liquid level control system, and a circulating filtration system; The trough body is used to hold the treatment liquid, and the material is mostly stainless steel (SUS304), which has the characteristics of corrosion resistance and easy cleaning. The roller system includes an upper roller and a lower roller, usually treated with rubber coating or carbon steel chrome plating, and pressure is applied through a pneumatic or hydraulic device; The liquid level control system automatically adjusts the liquid level in the trough to ensure uniform impregnation of the dyed grey fabric; The circulating filtration system can keep the liquid in the trough clean and prevent impurities from contaminating the dyed grey fabric.

[0046] The stenter squeezer has the following functions in this process: 1. Uniform wetting: Through immersion in clear water, the grey fabric maintains uniform humidity before entering the drying chamber, avoiding local overheating or uneven drying. 2. Removal of impurities: Clear water can wash away the remaining floating color, additives, or impurities after dyeing, providing a clean fabric surface for the subsequent printing process. 3. Size stability: Through uniform humidity control, the shrinkage difference of the fabric during high-temperature setting is reduced, improving size stability.

[0047] S5 Printing: Use a rotary screen printing machine, which is an inclined table printing machine in this embodiment. The rotary screen is 125 mesh, and 125 mesh is of medium fineness, which can clearly show details and at the same time ensure the permeability of the printing paste. Moreover, the permeability of the paste is good, not easy to block the mesh holes, and reduces the frequency of downtime for cleaning.

[0048] The circumference of the circular screen is 640 mm. The pattern uses 50% sand dot screen. The 50% sand dot screen can well attach the sizing water to the outer layer of the grey fabric, neither allowing too much sizing water to penetrate to the inner layer nor reducing the waterproof effect due to too little sizing water. Because when the sand dot density is too high (>70%), due to excessive sizing amount, there is a water repellent effect on both the front and the bottom. When the sand dot density is too low (<30%), too little sizing water leads to a poor waterproof effect on the front. When a person sweats and the sweat is absorbed by the fabric, obvious sweat watermarks will appear on the front.

[0049] The temperature of the printing oven is 150 °C, the machine speed is 25 m / min, and there are 20 magnetic rods; the 20 magnetic rods can provide uniform printing pressure, ensure that the sizing fully penetrates into the fabric interior, and at the same time avoid excessive penetration of the sizing.

[0050] The sizing order of the printing paste is as follows: S51: First add water, then add 10% fluorine-free waterproof agent, and stir evenly; S52: Add 1% cross-linking agent, and finally slowly add 1.3% thickener. After fully stirring evenly, control the viscosity at 10000 - 11000 cps. Generally speaking, the ions of the waterproof agent, cross-linking agent and thickener conflict with each other and are prone to produce flocs when stirred and mixed. The fluorine-free waterproof agent in this application is a weak cation. Using this sizing order and material ratio can reduce the conflict between anions and cations, thereby reducing the occurrence of flocs. Adding slowly will be a little better. And use 50% sand dot screen for the waterproof agent, so that the waterproof agent is not easily penetrated to the inner layer of the fabric. Try to avoid stopping the machine during the printing process, maintain a constant speed, and fully connect enough long guide cloth to ensure that the grey fabric passes through the machine evenly.

[0051] Using 50% sand dot screen, 20 magnetic rods and the sizing order of the printing paste can make the waterproof agent just coated on the bottom of the grey fabric, so that the bottom has a good waterproof effect. And it will not let the waterproof agent penetrate to the front of the grey fabric, and finally achieve the effect that the bottom of the grey fabric has waterproof property. The front of the grey fabric has a good sweat absorption effect. And because cotton itself has certain air permeability, the inner layer of the fabric can absorb sweat, and the outer layer has water repellent and breathable effects.

[0052] S6 Stentering: The stentering temperature is 150 °C and the fabric speed is 25 m / min. Connect the guide cloth at the head and tail. Try to avoid stopping the machine during the stentering process, maintain a constant speed, and fully connect enough long guide cloth to ensure that the grey fabric passes through the machine evenly.

[0053] The gram weight of the fabric is 165 g / m². The grey fabric is woven by a single-sided machine with a model of 30 inches and 28 needles. The effective width of the fabric is 167 CM.

[0054] The fabricated fabric is placed in an environment with a temperature of 20°C and a humidity of 65% for 4 hours. When water is dripped on the surface layer, it shows complete water repellency, achieving a single-sided waterproof effect. A drop of distilled water, approximately 0.04 mL, is dripped at a height of 1 cm from the fabric surface on the inner layer of the fabric, and the hydrophilic condition is observed for 60 seconds. The water can be completely absorbed without specular reflection, and the inner layer of the fabric achieves a single-sided hydrophilic effect. Then, look at the reverse side (i.e., the surface layer) of the inner layer after sufficient water penetration, and evaluate the degree of color fading with a gray scale. It reaches level 4 or above, achieving a sweat-free mark effect. Hazardous substances, especially fluorine-containing compounds, meet the restricted requirements of OEKO-TEX STANDARD 100 I (infant products) - Appendix 6. The fabric feels smooth and soft, has a good skin-friendly drape effect, and can withstand more than 5 washes.

Therefore, according to the technical solution of the present invention, without changing the essence of the present invention, those of ordinary skill in the art can propose various interchangeable structural forms and implementation methods. Therefore, the above specific implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.
