Abstract
Description
Technical Field
[0001] This utility model relates to a cashmere sweater, specifically an antibacterial and antistatic cashmere sweater. Background Technology
[0002] Cashmere sweaters are garments knitted from cashmere, prized for their soft, smooth feel, lustrous sheen, excellent warmth, and comfortable wear. However, ordinary cashmere sweaters have some drawbacks. For instance, the lack of antibacterial yarns in the knitting process results in low antibacterial properties, making them prone to bacterial growth and affecting hygiene and health. Furthermore, the absence of antistatic yarns causes static electricity to accumulate during wear and removal, leading to discomfort and attracting dust and lint, affecting the garment's appearance.
[0003] As people's living standards improve and their focus on health and comfort increases, higher demands are being placed on the functionality of cashmere sweater fabrics. Consumers expect cashmere sweaters to not only maintain their original warmth and comfort but also possess antibacterial and antistatic properties to enhance the wearing experience and ease of use. For example, in crowded places or daily life, antibacterial properties can effectively reduce the spread of bacteria and protect the wearer's health; while antistatic properties can avoid various problems caused by static electricity, such as clothes attracting dust and hair sticking up. Therefore, it is necessary to provide an antibacterial and antistatic cashmere sweater. Utility Model Content
[0004] The purpose of this invention is to provide an antibacterial and antistatic cashmere sweater, which is designed to have antibacterial and antistatic functions compared to ordinary wool sweaters.

[0011] Figure 1 This is a schematic diagram of the structure of the antibacterial and antistatic cashmere sweater involved in this utility model;
[0012] Figure 2 This is a structural schematic diagram of the antibacterial and antistatic fabric involved in this utility model;
[0013] In the picture: 1-body, 2-sleeves, 3-antibacterial layer, 4-warm insulation layer, 5-antistatic layer, 6-dot hot melt PU adhesive. Detailed Implementation
[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0015] Combination Figure 1 This embodiment provides a detailed description of an antibacterial and antistatic cashmere sweater, comprising: a body 1 and sleeves 2, which are connected by stitching; both the body 1 and sleeves 2 are made of antibacterial and antistatic fabric; the antibacterial and antistatic fabric includes an antibacterial layer 3, a thermal insulation layer 4, and an antistatic layer 5 arranged sequentially, which are composited by an array of dot-matrix hot-melt PU adhesive 6; the antibacterial layer 3 is weft-knitted from antibacterial yarn; the thermal insulation layer 4 is weft-knitted from thermal cashmere yarn; and the antistatic layer 5 is weft-knitted from antistatic yarn.
[0016] The dotted hot-melt PU adhesive 6 is distributed in an array, with gaps between adjacent dots of hot-melt PU adhesive 6. This ensures the breathability of the fabric on the one hand, and on the other hand, the fabric still has the elasticity of knitted fabric between adjacent dots of hot-melt PU adhesive 6.
[0017] Furthermore, the antibacterial yarn is a nanocrystalline functional modal cashmere elastic yarn blend. Specifically, the nanocrystalline functional modal cashmere elastic yarn blend is a 45 / 30 / 25 blend of modal / cashmere / elastic yarn, wherein the cashmere fibers are treated with far-infrared antibacterial functional crystal dispersion sizing agent, giving it far-infrared antibacterial function. Cashmere is a protein fiber, soft, smooth, and warm. The nanocrystalline functional treatment enhances its antibacterial function, and this function is permanent. Elastic yarn has a lobed yarn morphology, very similar to a spring, with a fiber crimp rate as high as 80%, making the fabric elastic. When blended with other fibers, the blended yarn has better wrinkle resistance and comfort. Modal fiber is regenerable, has a high wet modulus, excellent moisture absorption and breathability, and good strength and elongation. Its fabrics are smooth, breathable, and have excellent drape. Fabrics woven from nanocrystalline functional modal cashmere elastic yarn have far-infrared warmth retention and antibacterial and antipruritic functions. They have an antibacterial rate of 99% against Staphylococcus aureus, 77% against Escherichia coli, and 95% against Candida albicans, demonstrating excellent antibacterial properties.
[0018] Furthermore, the aforementioned warm cashmere yarn is an Australian wool-hemp-cashmere blended yarn. This Australian wool-hemp-cashmere blended yarn is a 60 / 30 / 10 blended yarn of Australian wool / hemp / cashmere with a linear density of 19.2 tex × 2. Australian wool has advantages such as soft, curly texture, uniform length, bright white color, and good elasticity; hemp fiber has excellent moisture absorption and breathability, is not prone to static electricity buildup, and has antibacterial, anti-mildew, and deodorizing functions, exhibiting significant killing and inhibitory effects against Staphylococcus aureus, Escherichia coli, and Candida albicans; cashmere is a thin layer of fine down growing on the outer skin layer of goats, hidden beneath the coarse hair, possessing the characteristics of softness, lightness, smoothness, warmth, and comfort. Therefore, the Australian wool-hemp-cashmere blended yarn not only has antibacterial properties but also combines the comfort and warmth of wool, the cool breathability of hemp, and the smooth, soft feel of cashmere.
[0019] Furthermore, the antistatic yarn is cashmere core-spun yarn, which includes a core filament and an outer sheath fiber. The core filament is a conductive filament, and the outer sheath fiber is cashmere fiber.
[0020] Furthermore, the conductive filament is a nylon-based copper ion conductive filament. Nylon-based copper ion conductive filament is produced by blending copper ion-containing compounds or nano-copper materials with nylon chips, and then manufacturing fibers through a melt spinning process. During spinning, copper ions are uniformly dispersed in the nylon matrix, forming conductive channels. Specifically, the nylon-based copper ion conductive filament has a fineness of 7.8 tex, a breaking strength of 32.31 cN / tex, and a resistivity of 0.01-0.10 Ω / cm.
[0021] Cashmere fibers are rich in crimp, soft, and have strong cohesion. When used as the outer fiber, cashmere core-spun yarn, spun with nylon-based copper ion conductive yarn as the core yarn, has better and more stable breaking strength and breaking elongation than pure cashmere yarn. Compared with cashmere fabrics of the same specifications, the bursting strength of cashmere core-spun yarn fabric is increased by 1.7 times, the maximum frictional static voltage is reduced by 86.5%, and the number of pills per unit area is reduced by 16.2%. This indicates that cashmere core-spun yarn is effective in improving the problems of cashmere fabrics being not durable, prone to static electricity, and prone to pilling.
[0022] 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.
