Description

Technical Field

[0001] This utility model relates to a cashmere yarn, specifically an anti-pilling and anti-insect cashmere yarn. Background Technology

[0002] Cashmere yarn is made from cashmere fibers and is widely used in clothing, accessories, and other fields due to its excellent warmth and softness. However, fabrics made from cashmere yarn are prone to pilling and moth damage. This is because the structure of cashmere fibers, including their scale layer, cortex layer, and cell membrane complex, makes it easy for the fibers to rub against and become entangled during wear and washing, causing the fiber ends to protrude from the fabric surface and form pills. Cashmere is a protein fiber containing various amino acids and other nutrients, making it susceptible to moth damage under suitable temperature and humidity conditions, affecting the lifespan and quality of cashmere products. Therefore, it is necessary to provide a pilling-resistant and moth-resistant cashmere yarn. Utility Model Content

[0003] The purpose of this invention is to provide a pilling-resistant and moth-proof cashmere yarn, which aims to enhance the anti-pilling and moth-proof properties of cashmere yarn and extend its service life.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: a pilling-resistant and moth-proof cashmere yarn, comprising: a yarn body, wherein the yarn body is formed by twisting a first yarn and a second yarn together; the first yarn comprises cashmere fiber yarn and low-melting-point polyester filament wrapped around the cashmere fiber yarn; the surface of the first yarn is coated with an moth-proof finishing agent; the second yarn comprises a core yarn and a covering fiber layer; the covering fiber layer covers the outside of the core yarn; the core yarn is an antibacterial and warm yarn, and the covering fiber layer is an anti-pilling fiber layer.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and warm yarn is coffee charcoal fiber yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial and warm yarn is a mulberry bark fiber antibacterial and warm blended yarn.

[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the anti-pilling fiber layer is an anti-pilling acrylic fiber layer.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the anti-pilling fiber layer is a double anti-pilling polyester fiber layer.

[0009] The beneficial effects of this utility model are as follows: Based on the anti-pilling and anti-insect cashmere yarn of this utility model, the low melting point polyester filament melts and adheres to the cashmere fibers after heat treatment, preventing the cashmere fiber yarn from burring out during friction, thereby improving the anti-pilling performance. The anti-insect finishing agent can give the cashmere fiber yarn a long-lasting anti-insect function. The second yarn not only has good antibacterial and warming properties, but also enhances the overall anti-pilling performance of the yarn. Attached Figure Description

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] Example 1

[0014] Combination Figure 1 This embodiment provides a detailed description of an anti-pilling and anti-moth cashmere yarn, comprising: a yarn body, wherein the yarn body is formed by twisting a first yarn 1 and a second yarn 2 together; the first yarn 1 comprises cashmere fiber yarn 3 and low-melting-point polyester filament 4 wrapped around the cashmere fiber yarn 3; an anti-moth finishing agent 5 is attached to the surface of the first yarn 1; the second yarn 2 comprises a core yarn 6 and a covering fiber layer 7; the covering fiber layer 7 covers the outside of the core yarn 6; the core yarn 6 is an antibacterial and warm yarn, and the covering fiber layer 7 is an anti-pilling fiber layer.

[0015] Specifically, in this embodiment, the low-melting-point polyester filament 4 is a modified polyester with a melting point of 110°C. The cashmere fiber yarn 3 wrapped with the low-melting-point polyester filament 4 is heat-treated at a temperature higher than 110°C. In this embodiment, the heat treatment temperature is 112°C, which melts and binds the low-melting-point polyester filament 4 to the cashmere fibers, preventing the cashmere fiber yarn 3 from fraying during friction, thereby improving its anti-pilling performance.

[0016] Specifically, in this embodiment, the insect-proof finishing agent 5 is the moth-proof finishing agent JF-86, which can give cashmere a long-lasting insect-proof function, while overcoming the disadvantages of refined naphthalene and extending the service life of cashmere fiber yarn 3.

[0017] Furthermore, the antibacterial and warm yarn is coffee charcoal fiber yarn. Coffee charcoal fiber is produced by calcining waste coffee grounds at temperatures above 1000℃ to form crystals, then grinding them into 100-300nm nano-sized powder, which is then added to polyester fibers to produce a functional polyester fiber. After blending, the coffee charcoal is evenly dispersed inside and on the surface of the polyester. Coffee charcoal fiber has many internal pores, which have good adsorption capabilities. It can effectively adsorb moisture from the skin surface and inhibit the growth of bacteria by suppressing surface moisture, thus playing an antibacterial role. At the same time, its porous structure can adsorb volatiles in the surrounding air, effectively deodorizing. The numerous pores inside coffee charcoal fiber can store a large amount of air, resulting in excellent warmth retention.

[0018] Furthermore, the anti-pilling fiber layer is an anti-pilling acrylic fiber layer. Anti-pilling acrylic fibers possess excellent softness, gloss, and smoothness, superior hand comfort, ultra-low tangling strength, and an anti-pilling performance level of 4 or higher, exhibiting excellent anti-pilling properties.

[0019] Example 2

[0020] The difference from Example 1 is that the antibacterial and warm yarn is a mulberry bark fiber antibacterial and warm blended yarn. Specifically, the mulberry bark fiber antibacterial and warm blended yarn is a 10 / 40 / 30 / 20 blended yarn of mulberry bark fiber / negative ion polyester fiber / cotton fiber / wool fiber. Mulberry bark fiber is a natural cellulose fiber with excellent moisture absorption and breathability, warmth retention, and good antibacterial properties. It has the characteristics of cotton and the advantages of linen fiber, with its outstanding performance being its antibacterial and deodorizing properties. Negative ion polyester fiber has health benefits such as regulating air, absorbing odors, activating cells, and improving immunity. Cotton fiber has good moisture absorption and breathability and comfort, while wool fiber has good elasticity, moisture absorption, and warmth retention. The mulberry bark fiber antibacterial and warm blended yarn has the advantages of warmth and comfort, and its antibacterial rate against Escherichia coli can reach 75.9%, demonstrating a good antibacterial effect.

[0021] Example 3

[0022] The difference from Example 1 is that the anti-pilling fiber layer is a double-anti-pilling polyester fiber layer. Double-anti-pilling polyester fiber refers to ordinary polyester fiber modified through chemical or physical methods to obtain polyester fibers with anti-pilling and antistatic properties. The breaking strength, breaking strength unevenness, and breaking elongation of double-anti-pilling polyester fiber are all lower than those of ordinary polyester fiber, approaching those of viscose fiber. Fabrics woven from its yarns have easily shed fuzz, preventing the formation of numerous pills and achieving a good anti-pilling effect. Its internal fiber structure is porous, allowing moisture to easily penetrate and providing good wicking properties, which enhances the electrical conductivity of the double-anti-pilling polyester fiber and provides excellent antistatic properties, thus improving the anti-pilling performance of the yarn.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
