Description

Technical Field

[0001] The invention relates to the technical field of blended fabric manufacturing, in particular to a method for manufacturing a pilling-resistant suede wool blended fabric. Background Art

[0002] Suede fabric is a basic category of wool worsted and woolen fabrics, with a large market share, especially in the autumn and winter seasons. The pilling problem of suede fabrics has always been a pain point in the industry and is often complained by consumers. The pilling problem is mainly divided into two stages: one is that the head end of the fiber is exposed to the surface of the fabric due to friction and external force, and then the head end fiber is further removed from the yarn under the action of external force, and entangled with each other to form pills. If the breaking strength of the fiber in the fabric is large, the pills are not easy to fall off and it will develop into a serious pilling problem.

[0003] Based on the above process of pilling formation, there are two main ways to solve pilling in the past: one is to reduce the exposure of the fiber head, such as resin finishing, anti-pilling additives, etc.; Another method is to reduce the strength of the fiber, such as using anti-pilling fibers. Even if pilling occurs, it will fall off under the action of external force, thereby reducing the accumulation of pilling on the fabric surface.

[0004] Suede fabrics themselves require a large number of fiber ends to be exposed on the surface of the fabric to form a suede effect. From the perspective of pilling, the first stage has been completed, making it more difficult to solve the anti-pilling problem. In the field of wool spinning, wool blended fabrics are often blended with synthetic fibers such as polyester, nylon or acrylic. These fibers are strong and difficult to fall off once pilling occurs. Therefore, it is difficult to produce good results in solving the pilling problem of suede wool blended fabrics using the previous methods. Summary of the invention

[0005] Technical issues solved In view of the shortcomings of the prior art, the present invention provides a method for manufacturing a fuzz- and pilling-resistant suede wool blended fabric, which solves the problem that the suede fabric surface is prone to pilling.

[0006] Technical Solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for manufacturing anti-pilling suede wool blended fabric, The invention comprises using a "welded" polyester fiber, wherein the "welded" polyester fiber has a core-shell structure, wherein the core-shell structure comprises a low-melting-point shell portion and a high-melting-point core portion, wherein the low-melting-point shell portion surrounds the high-melting-point core portion; The "welded" polyester fiber is blended with wool, ordinary polyester, or other fibers, and the low-melting-point shell of the "welded" polyester fiber is melted through a high-temperature shaping process, so that the low-melting-point shell is blended and bonded with the wool, ordinary polyester, or other fibers; After the bonded product is cooled by the cooling component, the molten part solidifies to form a stable structure and state. Through the "welding" polyester fiber, the fibers in the raised fabric yarn are welded together, so that even if the suede fabric is subjected to friction and external force in the later stage, the fiber heads will not be further exposed because the fibers are fixed to each other. Although the suede fabric itself has exposed fibers, the exposed fibers are relatively short and not entangled with each other. In addition, the roots of the fibers are "welded" inside the yarn, which is not easy to slide and form pills.

[0007] Preferably, the other fiber blends include but are not limited to nylon, regenerated polyester fiber, viscose fiber, acrylic fiber, and regenerated cellulose fiber.

[0008] Preferably, the melting temperature of the low-melting-point shell portion is 120°C-150°C.

[0009] Preferably, the high temperature setting temperature of the high temperature setting process is 150°C-175°C, and the setting time is 45S-55S. During the high temperature setting process, the temperature generated can melt the low melting point shell part and keep the high melting point core part unmelted, thereby meeting the requirements of blended bonding.

[0010] Preferably, the cooling component is a cooling roller, and the surface temperature of the cooling roller is 10° C.-25° C. The cooling roller is cooled by passing cooling water to reduce the surface temperature of the cooling roller, and the textile passes through the cooling roller to achieve cooling and shaping of the textile.

[0011] Preferably, the content of the "welded" polyester fiber is 5-20%, the content of wool is 30%-95%, and the content of other fibers is the remaining proportion.

[0012] Beneficial Effects The present invention provides a method for manufacturing a fuzz- and pilling-resistant fleece wool blended fabric, which has the following beneficial effects: The present invention welds the fibers in the raised fabric yarn together by setting up "welding" polyester fibers, so that even if the suede fabric is subjected to friction and external force in the later stage, the fiber heads will not be further exposed because the fibers are fixed to each other. Although the suede fabric itself has exposed fibers, the exposed fibers are relatively short and not entangled with each other. Moreover, the roots of the fibers are "welded" inside the yarn and are not easy to slide, and thus are not easy to form pills. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] refer to Figure 1 The present invention provides a method for producing a fuzz- and pilling-resistant fleece wool blended fabric. The invention comprises using a "welded" polyester fiber, wherein the "welded" polyester fiber has a core-shell structure, the core-shell structure comprises a low-melting point shell part 1 and a high-melting point core part 2, the low-melting point shell part 1 surrounds the high-melting point core 2, the content of the "welded" polyester fiber is 5-20%, the content of wool is 30%-95%, and the content of other fibers is the remaining proportion; The "welded" polyester fiber is blended with wool, ordinary polyester, or other fibers, and the low melting point shell part 1 of the "welded" polyester fiber is melted through a high temperature setting process, and the melting temperature of the low melting point shell part 1 is 120°C-150°C, so that the low melting point shell part 1 and the wool, ordinary polyester, or other fibers are blended and bonded together; The high-temperature setting process uses the principle of heat setting. Heat setting is a process that uses heat energy to relax and rearrange the macromolecular chain segments in the fabric fibers, thereby allowing the fibers to reach a stable state, eliminating the internal stress generated in the fabric during processing, improving the stability of the fiber shape, and improving the physical and mechanical properties of the fabric, such as elasticity, wear resistance and setting effect. The high-temperature setting process includes wet heat setting: suitable for synthetic fibers with strong hydrophilicity, such as nylon and acrylic, which can make the fabric feel soft and full; dry heat setting: mainly used for polyester and its blended fabrics, and is heated by hot air or infrared radiation. The commonly used equipment in the high-temperature setting process includes needle-chain heat setting machines, hot air stentering setting machines, etc., which can be selected according to specific needs.

[0017] The high temperature setting temperature of the high temperature setting process is 150°C-175°C. During the high temperature setting process, the temperature generated can make the low melting point shell part 1 melt, and the high melting point core part 2 remain unmelted, thereby meeting the requirements of blended bonding.

[0018] The setting time is 45S-55S, and other fiber blends include but are not limited to nylon, recycled polyester fiber, viscose fiber, acrylic fiber, and regenerated cellulose fiber; Nylon, also known as nylon, is a synthetic fiber with excellent wear resistance, high strength, good moisture absorption and good elastic recovery. It is second only to vinylon among synthetic fibers. Its lightness and elastic recovery make it suitable for making all kinds of clothing. Nylon is often used to make sportswear, mountaineering clothes, winter clothing, socks, etc.

[0019] Recycled polyester fiber is a fiber made by recycling and reusing waste polyester materials, such as waste polyester bottle flakes, polyester fabrics, etc. It has important environmental significance and a wide range of applications. It is often used to make high-end filling products such as pillows, cushions, winter quilts, etc., and can be used in women's tops, shirts, underwear, and jackets.

[0020] Viscose fiber is a regenerated cellulose fiber made from natural wood pulp through chemical processing. Viscose fiber is widely used in various textiles and clothing due to its excellent moisture absorption and air permeability, good dyeing performance and soft feel. It is often used to make underwear, T-shirts, shirts, skirts, bedding, curtains, towels, etc., especially clothes with high requirements on comfort and breathability.

[0021] Acrylic is a synthetic fiber, the main component of which is polyacrylonitrile. This fiber is popular because of its wool-like properties and is known as "artificial wool". Polyacrylonitrile is a polymer material obtained by free radical polymerization of acrylonitrile monomers. It is usually in the form of white powder with a density between 1.14 and 1.15 g / cm³. Its performance is similar to that of wool, but it has better elasticity and can maintain a 65% rebound rate when stretched by 20%. Its warmth retention is about 15% higher than that of wool, and the fiber is fluffy and curly, with a soft feel. Acrylic also has excellent light-fastness. Even if exposed to the sun, its strength only decreases by about 20%, which makes it widely used in outdoor products such as curtains and tarpaulins.

[0022] Regenerated cellulose fiber is made from natural cellulose (cotton, linen, bamboo, trees, shrubs, etc.). Its chemical structure is not changed, but only the physical structure of natural cellulose is changed to produce regenerated cellulose fiber with better performance. It feels soft, plump, and smooth, has excellent drape and silk-like luster; it has high thermal and light stability and does not generate static electricity; its strength and elongation can meet the needs of most textiles, and it has good spinnability. The short fiber can be spun purely or blended with other textile fibers. The fabric is soft, smooth, breathable, comfortable to wear, and has bright colors and good color fastness after dyeing. It is suitable for making underwear, outerwear and various decorative items.

[0023] After the bonded product is cooled by the cooling component, the molten part solidifies to form a stable structure and state. The cooling component is a cooling roller, and the surface temperature of the cooling roller is 10℃-25℃; The cooling roller is an industrial equipment, which is mainly used for cooling high-temperature materials during material processing. This equipment is widely used in calendering film, adhesive tape coating, textile and other industries, and reduces deformation and improves product quality by reducing the temperature of the material; the working principle of the cooling roller is to reduce the temperature of the roller surface by passing cooling water, thereby taking away the heat of the material in contact with the roller. High-quality cooling rollers should have sufficient rigidity and hardness to ensure that they will not bend and deform under heavy load, and the surface has sufficient wear resistance and corrosion resistance. The present invention is to add a certain amount of polyester fiber with a low melting point core-shell structure in the production process of wool fabrics, and make the polyester fiber evenly distributed to all parts of the yarn through multiple combing and merging, and make the fabric form a suede effect through the usual spinning, weaving, finishing and shrinking process, and finally make the shell part of the "welded" polyester fiber form a molten state through high temperature treatment, so that the wool and other fibers around the fiber are "welded" together, and the molten part solidifies after the temperature is reduced, so as to form a stable structure. Because the root of the fiber in the yarn is fixed, the pilling phenomenon of the suede fabric is reduced.

[0034] Working principle: In the production process of wool fabrics, a certain amount of polyester fiber with a core-shell structure of low melting point is added to the present invention. Through multiple combing and merging, the polyester fiber is evenly distributed throughout the yarn. After the usual spinning, weaving, finishing and shrinking processes, the fabric forms a suede effect. Finally, through high-temperature treatment, the shell part of the "welded" polyester fiber is molten, thereby "welding" the wool and other fibers around the fiber together. After the temperature is lowered, the molten part solidifies to form a stable structure. Since the roots of the fibers in the yarn are fixed, the pilling phenomenon of the suede fabric is reduced.
