Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to an application method of cashmere fancy yarn in tweed fabrics. Background Art

[0002] In the textile industry, tweed fabrics are highly favored for their unique texture and warmth retention properties, and are particularly widely used in high-end clothing and home decoration. Traditional tweed fabrics are mostly woven with wool, cotton and other fibers. Although these fibers perform well in terms of warmth retention and durability, they still need to be improved in terms of aesthetics, comfort and functionality.

[0003] In recent years, with the continuous advancement of textile technology and the increasing demand of consumers for textile quality, cashmere fancy yarn has gradually entered people's field of vision. As a high-end textile raw material, cashmere has become an ideal choice for making high-end textiles with its delicate feel, good warmth retention and breathability. Fancy yarns are made through special textile processes to form various unique patterns and designs on the surface of the yarn, thus giving the fabric a richer visual effect and touch.

[0004] However, the application of fancy cashmere yarn in the production of tweed fabrics faces many technical challenges. On the one hand, cashmere fibers are relatively delicate and easily deformed or shrunk by the external environment, which requires effective measures to maintain the stability of their shape during the production process. On the other hand, the special structure of fancy yarns makes it easy for yarn entanglement and breakage to occur during the weaving process, and the textile process needs to be optimized to ensure the quality and output of the fabric. Summary of the invention

[0005] In view of the above technical problems, the present invention proposes a method for applying cashmere fancy yarn to tweed fabric. The method not only effectively enhances the shrinkage resistance, thermal stability and softness of the cashmere fancy yarn through a designed additive formula and a series of process steps, but also improves the weaving efficiency and quality of the fabric. At the same time, the method also retains the unique beauty and comfort of the cashmere fancy yarn, so that the tweed fabric finally produced is more superior in performance, meeting the consumer's demand for high-end textiles.

DETAILED DESCRIPTION

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be used for other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0026] The present invention provides a method for applying cashmere fancy yarn to tweed fabric, comprising the following steps:

[0027] Step 1: Yarn preparation: Select high-quality cashmere fibers, wash, comb and refine them to ensure the fineness and uniformity of the fibers, and use ring spinning or air-jet spinning to prepare cashmere fancy yarns.

[0028] Step 2: Preparation of cashmere fiber morphology stabilizing additives: preparing additives including polyurethane-silane composite polymer, epoxy resin or polyester resin, silicone softener and octadecenoic acid ester or stearic acid ester to enhance the shrinkage resistance, thermal stability and softness of the fabric; wherein, the preparation ratio and function of the above-mentioned cashmere fiber morphology stabilizing additives are as follows:

[0029]

[0030]

[0031] Step 3: Yarn pretreatment: Degreasing, cleaning, washing and drying the prepared cashmere fancy yarn to ensure that the yarn surface is clean and free of impurities, in preparation for the subsequent additive impregnation;

[0032] Degreasing and cleaning: Use mild detergent to remove grease and impurities on the yarn surface to ensure that the additives can be evenly attached to the fiber surface;

[0033] Washing and Drying: After cleaning, use water at an appropriate temperature to remove detergent residues and completely dry the yarn to prepare for subsequent impregnation and cross-linking reactions.

[0034] Step 4: Additive impregnation treatment: the pre-treated cashmere fancy yarn is immersed in an impregnation solution containing a cashmere fiber morphology stabilizing additive, and the impregnation time, temperature and solution concentration are controlled to make the cashmere fiber morphology stabilizing additive uniformly adhere to the yarn surface; wherein,

[0035] Formula requirements for the concentration of the impregnation liquid: Control the concentration of additives in the impregnation liquid within the range of 20%-25% to ensure that the additives are evenly adsorbed on the surface of each fiber, and adjust the pH value of the impregnation liquid to 6.0 to 7.0 and the viscosity of the impregnation liquid to 100 to 300 cP to ensure the uniformity and permeability of the impregnation liquid.

[0036] This pH range ensures the synergistic effect between the components in the formula, while also avoiding damage to the cashmere fibers and maintaining the stability of the additives; this viscosity range ensures the fluidity and impregnation effect of the solution, enabling the cashmere fibers to evenly absorb the components in the formula without causing excessive accumulation or uneven coating.

[0037] Control of immersion time: Soak the cleaned cashmere fancy yarn in the additive solution for 15-20 minutes; ensure that each fiber is evenly soaked.

[0038] Control of impregnation temperature: The impregnation process should be maintained at 20-30℃ to avoid excessively high temperature causing changes in fiber properties.

[0039] Step 5: Drying and cross-linking reaction: Dry the impregnated yarn to remove excess water and solvent, and then promote the cross-linking reaction between the cashmere fiber morphology stabilizing additives at an appropriate temperature to form a stable three-dimensional structural network;

[0040] The drying temperature is controlled at 100-120°C and the drying time is 15-30 minutes;

[0041] The temperature of the cross-linking reaction is controlled at 140-160°C for 5-10 minutes. This temperature can promote the cross-linking reaction between polyurethane, silane and epoxy resin to form a three-dimensional structural network, ensuring the thermal stability and shrinkage resistance of the cashmere fiber. It is necessary to avoid long time which may cause the fiber to harden.

[0042] Step 6: Spinning and weaving: Use the cashmere fancy yarn that has been treated with impregnation and cross-linking reaction, and adopt high-density weaving technology to weave it into tweed fabric;

[0043] According to the characteristics of fancy yarns, the weaving density and texture are adjusted to make the surface of tweed fabric present rich texture and layers; by controlling the weaving tension, the uniform distribution of yarn is ensured to avoid uneven fabric surface or yarn falling off.

[0044] Step 7: Heat setting treatment: Heat setting treatment is performed on the woven tweed fabric to fix the yarn shape, avoid shrinkage and deformation, and enhance the stability and durability of the fabric;

[0045] The heat setting temperature of the tweed fabric is about 160℃, and the heat setting time is controlled within 5-10 minutes; heat setting helps the cashmere fancy yarn to fix its shape, avoid shrinkage and deformation, and avoid affecting the softness of the fiber for too long.

[0046] Step 8. Post-processing and softness adjustment: Soften the tweed fabric after heat setting to enhance the comfort and softness of the fabric.

[0047] Use silicone softener or natural softener to soften tweed fabric. The addition of softener can avoid hardening of fibers and keep the fabric soft and smooth.

[0048] The softener is added by spraying or dipping to ensure uniform distribution; the temperature is controlled between 50-70℃ and the processing time is 15-30 minutes to ensure that the softener can fully exert its effect.

[0130] The present application adopts the methods of the above nine embodiments to prepare tweed fabrics, and conducts preliminary observation and hand feel analysis on the tweed fabrics:

[0131] The additives in the proportion of Example 1 can effectively enhance the shrinkage resistance and softness of the fabric, and the final fabric has a good hand feel and is suitable for high-end clothing.

[0132] The polyurethane-silane composite polymer ratio of Example 2 is relatively high, which enhances the thermal stability of the fabric, but may cause the fabric to be slightly stiff, which is suitable for outerwear products.

[0133] The post-treatment temperature of Example 3 is relatively high, which may lead to enhanced softness of the fabric and is suitable for products that require a comfortable feel.

[0134] The weaving density of Example 4 is relatively high, and it is suitable for making thick winter fabrics, and the warmth retention of the fabrics is relatively good.

[0135] The viscosity of the impregnation liquid in Example 5 is relatively high, which may result in more uniform adhesion of the additive and better shrinkage resistance and softness of the fabric.

[0136] The polyurethane-silane composite polymer ratio of Example 6 is relatively high, which enhances the thermal stability of the fabric and is suitable for making outerwear products.

[0137] The epoxy resin ratio of Example 7 is relatively high, which may enhance the wear resistance of the fabric and is suitable for making clothing for daily wear.

[0138] The stearate ratio in Example 8 is relatively high, which may enhance the waterproofness of the fabric and is suitable for making outdoor clothing.

[0139] The additive ratio of Example 9 is balanced, the overall performance of the fabric is good, and it is suitable for various uses.

[0140] Furthermore, the present application tested the finished tweed fabrics prepared in the above nine embodiments, and the test items included shrinkage resistance test, morphological stability test, softness test, and durability test; and then analyzed their applicability as shown in the following table:

[0141]

[0142]

[0143] The ratio of the additives, the conditions of the impregnation treatment, the parameters of the drying and cross-linking reactions, etc. of the present invention have a significant impact on the performance of the final fabric. Different yarn preparation processes (ring spinning or air-jet spinning) and weaving densities will affect the texture and layering of the fabric.

[0144] Yarn preparation method: Ring spinning and air-jet spinning each have their own advantages. Ring spinning may produce yarn with better strength and uniformity, while air-jet spinning may improve production efficiency.

[0145] Additive ratio: polyurethane-silane composite polymer mainly enhances thermal stability, epoxy resin may improve wear resistance, silicone softener increases softness, octadecenoic acid ester may affect waterproofness. Different ratios can meet the performance requirements of different fabrics.

[0146] Impregnation conditions: The concentration, pH value, viscosity of the impregnation solution, the impregnation temperature and time have an important influence on the adhesion effect and uniformity of the additives. Appropriate conditions can ensure that the additives effectively penetrate into the yarn and improve the performance of the fabric.

[0147] Drying and cross-linking reaction: Control of drying temperature and time is crucial to removing excess moisture and solvents, while cross-linking reaction helps to form a stable three-dimensional structural network and enhance the stability of the fabric.

[0148] Textile and weaving: High-density weaving technology can improve the compactness and durability of the fabric, but too high density may affect the feel. Therefore, the weaving density needs to be adjusted according to the purpose of the fabric.

[0149] Heat setting treatment: Heat setting helps to fix the yarn shape and improve the stability and durability of the fabric. The treatment temperature and time need to be adjusted according to the fabric material and performance requirements.

[0150] Post-treatment and softness adjustment: Using silicone softeners or natural softeners can enhance the comfort and softness of the fabric. The processing temperature and time have an important influence on the softening effect.

[0151] It should be noted that in the textile industry, the use of high-density weaving technology refers to increasing the density of the fabric by increasing the number of yarns per square inch during the fabric manufacturing process. Generally speaking, the description of density is usually measured by the number of yarns (threads) per square inch. The following is the approximate range of high density and moderate density under normal circumstances:

[0152] 1. Higher density: Generally speaking, fabrics with higher density usually have a higher number of threads per square inch, usually above 200 threads; this high-density fabric has a tighter structure, a smoother surface, and a delicate feel, and is suitable for products that require high strength and durability.

[0153] 2. Moderate density: Fabrics with moderate density usually have a moderate number of threads per square inch, usually between 100-200 threads; this type of fabric has a certain degree of breathability and comfort while maintaining a certain strength and durability.

[0154] Those skilled in the art should understand that the embodiments of the present invention shown in the above description are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
