Description

Technical Field

[0001] This utility model relates to a cashmere sweater, specifically a self-heating and warm cashmere sweater. Background Technology

[0002] Cashmere sweaters, made from natural cashmere fibers, are renowned for their soft texture, smooth feel, excellent warmth, and breathability, making them a favorite among consumers and widely used in autumn and winter clothing. Whether for everyday wear, outdoor leisure, or the need for warmth in cold regions, cashmere sweaters hold an important place due to their superior performance.

[0003] However, as people's demand for warmth continues to rise, traditional cashmere sweaters have gradually revealed some limitations. In terms of warmth retention, traditional cashmere sweaters mainly rely on the fluffy structure of cashmere fibers to trap air, thereby blocking heat transfer. Their warmth retention effect depends more on the natural properties of the fibers and the thickness of the fabric, lacking active heat generation capability. When in extremely cold environments or with low levels of physical activity, passive warmth alone is insufficient to maintain a sufficient perceived temperature, failing to meet people's demand for continuous and efficient warmth. Therefore, this application provides a self-heating cashmere sweater. Utility Model Content

[0004] The purpose of this invention is to provide a self-heating cashmere sweater that retains the excellent properties of natural cashmere while also possessing self-heating capabilities.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A self-heating and warm cashmere sweater includes: a cashmere sweater body, which comprises a garment body and sleeves, the garment body and sleeves being connected by sewing; both the garment body and sleeves are made of self-heating and warm cashmere fabric; the self-heating and warm cashmere fabric is a warp-knitted checkered structure woven from yarns threaded by three guide bars (GB1, GB2, and GB3); the yarn padding numbers and threading methods of GB1, GB2, and GB3 are as follows: GB1: (1-1 / 0-0)×2 / 2-3 / 1-0 / / Two through three open spaces; GB2: (2-3 / 1-0)×2 / 1-1 / 0-0 / / Two gaps and three penetrations; GB3: 1-0 / 1-2 / / Full penetration; GB1 incorporates self-heating and warming yarn; GB2 incorporates antibacterial and warming yarn; and GB3 incorporates cashmere yarn.

Detailed Implementation

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

[0013] Example 1 Combination Figure 1-2 This embodiment provides a detailed description of a self-heating cashmere sweater, comprising: a sweater body, the sweater body including a garment body 1 and sleeves 2, the garment body 1 and sleeves 2 being connected by sewing; both the garment body 1 and sleeves 2 are made of self-heating cashmere fabric; the self-heating cashmere fabric is a warp-knitted checkered structure woven from yarns threaded by three combs (GB1, GB2, and GB3); the yarn padding numbers and threading methods of GB1, GB2, and GB3 are as follows: GB1: (1-1 / 0-0)×2 / 2-3 / 1-0 / / Two through three open spaces; GB2: (2-3 / 1-0)×2 / 1-1 / 0-0 / / Two gaps and three penetrations; GB3: 1-0 / 1-2 / / Full penetration; GB1 incorporates self-heating and warming yarn; GB2 incorporates antibacterial and warming yarn; and GB3 incorporates cashmere yarn.

[0014] In terms of weaving structure, GB1 and GB2 self-heating cashmere fabrics use two cooperating multi-needle warp-knitted combs with opposite yarn-threading patterns. GB3 uses a warp-knitted plain weave with full-length yarn-threading, forming a warp-knitted checkered structure with horizontal and vertical squares, providing a good imitation woven effect. Cashmere yarn is spun from cashmere fibers, which are the fine down at the base of the coarse hair of goats. Cashmere fibers possess excellent properties such as softness, lightness, smoothness, warmth, and crispness, giving cashmere sweaters a soft and smooth feel.

[0015] Furthermore, the self-heating insulating yarn is a blend of wool, coffee charcoal, and polyester moisture-absorbing and heat-generating fibers. Specifically, the wool, coffee charcoal, and polyester moisture-absorbing and heat-generating fiber blended yarn is a blend of 50% wool, 40% coffee charcoal polyester, and 10% moisture-absorbing and heat-generating fibers. Coffee charcoal polyester is obtained by calcining waste coffee grounds at temperatures above 1000℃ to optimize the crystal structure and pore size. Using nanotechnology, it is micronized and ground into 100-300nm nano-sized powder, which is then added to polyester fibers, resulting in a yarn with heat storage, heat preservation, antibacterial, and deodorizing functions. The moisture-absorbing and heat-generating fiber is a functional fiber composed of acrylic acid, sodium acrylate, and acrylamide, possessing moisture-absorbing, heat-generating, and deodorizing properties. The wool, coffee charcoal, and polyester moisture-absorbing and heat-generating fiber blended yarn achieves a heat rise of up to 4℃ and a deodorization rate of 94%, demonstrating excellent moisture absorption, heat generation, and deodorization effects.

[0016] Furthermore, the antibacterial and warm yarn is an Australian wool, hemp, and cashmere blended knitting yarn. Specifically, the Australian wool, hemp, and cashmere blended knitting yarn is a 60 / 30 / 10 blended knitting yarn of Australian wool / hemp / cashmere. Australian wool has advantages such as soft and 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, with significant killing and inhibitory effects on Staphylococcus aureus, Escherichia coli, and Candida albicans; cashmere is a thin layer of fine down that grows on the outer skin layer of goats, hidden at the base of the coarse hair, and has the characteristics of being soft, light, smooth, warm, and cool. Therefore, the Australian wool, hemp, and cashmere blended knitting yarn not only has antibacterial function, but also combines the comfort and warmth of wool, the coolness and breathability of hemp, and the smooth and soft feel of cashmere.

[0017] Example 2 The difference from Example 1 is that the self-heating thermal yarn is an acrylic-cupramolecular fiber thermal blended yarn. Specifically, the acrylic-cupramolecular fiber thermal blended yarn is made of 60% ultra-fine denier anti-pilling thermal acrylic fiber and 40% cupramolecular fiber. Compared with ordinary fibers, ultra-fine denier anti-pilling thermal acrylic fiber has moisture-absorbing and heat-generating functions. This is because during the fiber production process, special moisture-absorbing and heat-generating materials are mixed into the spinning solution. These heat-generating materials can absorb some of the moisture from the outside and convert it into heat, effectively preventing heat loss and the invasion of cold air from the outside, resulting in good warmth retention. Furthermore, the cross-section of ultra-fine denier anti-pilling thermal acrylic fiber is an irregular polygon, and the fiber surface is rough. After being spun into yarn, the cohesion between fibers is large, making it less prone to pilling. The micropores and grooves on the fiber surface give the fiber good wicking function, facilitating the transfer of moisture absorbed by the fiber to the outer layer of the fabric. Cupro fiber is a cellulose fiber processed from cotton lint. It has good moisture absorption, softness, and skin-friendly properties. Therefore, the heat-generating acrylic cupro fiber blended yarn can take into account both the heat-retaining function of moisture absorption and heat generation and the comfort performance.

[0018] Example 3 Based on Example 1 or Example 2, the cashmere yarn is an anti-mite cashmere yarn. Specifically, the anti-mite cashmere yarn is produced by dyeing loose cashmere fibers, followed by anti-mite treatment, and then spinning the yarn using a woolen yarn spinning technique. Specifically, the anti-mite treatment uses anti-mite finishing agent SCJ-195 at a dosage of 2%-4% of the fiber weight. The finishing process is as follows: after dyeing, formic acid is added to a water bath with a liquor ratio of 1:60 for neutralization and the mixture is run for 10 minutes. Then, 4% of anti-mite finishing agent SCJ-195 is added, the temperature is raised to 30°C and held for 20 minutes, followed by rinsing with clean water. Then, 1.5% softener is added to a water bath with a liquor ratio of 1:60, the temperature is raised to 30°C and held for 20 minutes, and the water is drained directly. Finally, 2%-4% of anti-mite finishing agent SCJ-195 is added to a water bath with a liquor ratio of 1:60, the temperature is raised to 30°C and held for 20 minutes, the water is drained directly, and after thorough rinsing, the yarn is allowed to cool naturally to complete the anti-mite treatment.
