Abstract
Description
Technical Field
[0001] This utility model relates to a wool sweater, specifically an antistatic, heat-generating, and warm wool sweater. Background Technology
[0002] Wool, as a natural protein fiber, possesses excellent moisture absorption and breathability, softness and skin-friendliness, and natural warmth, making it a core raw material for winter knitwear for a long time. The warmth retention principle of traditional wool sweaters mainly relies on the fluffy structure of wool fibers to trap still air and reduce heat loss through conduction. Its warmth retention performance is essentially passive heat retention, relying on the natural properties of the fiber itself.
[0003] With the diversification of people's living scenarios, such as large temperature differences between indoors and outdoors in winter, frequent contact with electronic devices, and dry climates, wool fibers, due to their high dielectric constant and strong insulation, are prone to static electricity buildup due to friction between the fibers and skin, clothing, and the environment, especially in dry environments such as indoor air conditioning in winter, the heating season in northern regions, or during wear. Static electricity not only causes wool sweaters to attract dust and hair, affecting the neatness of the garment, but it can also cause electric shocks when the body comes into contact with metal objects, such as door handles, elevator buttons, or electronic devices, affecting wearing comfort. Traditional wool sweaters only reduce heat loss by trapping air and do not have an active heating function. In low-temperature environments, such as outdoor commuting, unheated places, or for people with high warmth requirements, such as the elderly, those with cold constitutions, and outdoor workers, simple passive heat trapping is insufficient to meet the need for continuous warmth. Therefore, this application provides an antistatic heating and warm wool sweater. Utility Model Content
[0004] The purpose of this invention is to provide an antistatic, heat-generating, and warm wool sweater, which, compared with traditional wool sweaters, has a heating function, better warmth retention, and antistatic function to reduce the generation of static electricity.
[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an antistatic, heat-generating, and warm wool sweater, comprising: a sweater body, wherein the sweater body is formed by sewing together a garment body and sleeves, both of which are made of antistatic, heat-generating, and warm knitted fabric; the antistatic, heat-generating, and warm knitted fabric is woven from odd-numbered yarns, even-numbered yarns, and padding yarns, wherein the odd-numbered yarns include heat-generating acrylic yarns, and the even-numbered yarns include wool yarns and antistatic yarns; the wool yarns and antistatic yarns are arranged in a 5:1 ratio.
[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the pattern of the antistatic heat-generating and warm knitted fabric is a diamond pattern, the center of the diamond pattern is woven with an even number of yarns on the surface layer, and the edge of the diamond pattern is woven with an odd number of yarns on the surface layer. The loops connect the outer and inner layers to form a seam, and the padding yarn is used to pad between the outer and inner layers to form a sandwich layer.
[0007] Based on the above scheme and as a preferred embodiment of the above scheme: the wool yarn is Merino machine-washed wool yarn.
[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the antistatic yarn is graphene-modified PET fiber.
[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the padding yarn is polyester low elastic yarn.
[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the odd-numbered yarns further include antibacterial nylon yarns, and the heat-generating acrylic yarns and antibacterial nylon yarns are arranged and threaded in a 5:1 ratio.
[0011] The beneficial effects of this utility model are as follows: Based on the antistatic heating and warm wool sweater of this utility model, the heating acrylic fiber can absorb external moisture and human sweat and convert them into heat to achieve active heating; the antistatic heating and warm knitted fabric forms a closed interlayer between the outer layer and the inner layer, which can effectively lock in still air. Combined with wool yarn, it achieves a combination of active heating and passive heat retention. The warming effect is significantly better than that of traditional wool sweaters that only rely on passive heat retention. The antistatic yarn is used to discharge the static charge generated by fiber friction, reducing the occurrence of static electricity. Attached Figure Description

Detailed Implementation
[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0014] Example 1 Combination Figure 1This embodiment provides a detailed description of an antistatic, heat-generating, and warm wool sweater, comprising: a sweater body, wherein the sweater body is formed by sewing together a garment body 1 and sleeves 2, both of which are made of antistatic, heat-generating, and warm knitted fabric; the antistatic, heat-generating, and warm knitted fabric is woven from odd-numbered yarns, even-numbered yarns, and padding yarns, wherein the odd-numbered yarns include heat-generating acrylic yarns, and the even-numbered yarns include wool yarns and antistatic yarns; the wool yarns and antistatic yarns are arranged in a 5:1 ratio.
[0015] Compared to ordinary fibers, heat-generating acrylic fibers have moisture-absorbing and heat-generating functions because moisture-absorbing and heat-generating materials are incorporated during the spinning process. These materials can absorb some of the moisture from the outside environment and convert it into heat. They also have a breathable function; when the body sweats, the heat-generating acrylic fibers can quickly absorb the moisture produced by the body through moisture absorption and heat generation and transfer it to the surface of the fabric, keeping the body dry. The cross-section of heat-generating acrylic fibers is an irregular polygon, and the fiber surface has micropores and grooves. The micropores give the fibers good wicking function, and the surface grooves facilitate the transfer of the moisture absorbed by the fibers to the outer layer of the fabric.
[0016] Furthermore, the pattern of the antistatic heating and warm knitted fabric is a diamond pattern. The center of the diamond pattern is woven with an even number of yarns on the surface layer, while the border of the diamond pattern is woven with an odd number of yarns on the surface layer. The loops connect the outer and inner layers to form a seam, and padding yarn is used to pad between the outer and inner layers to form a sandwich layer.
[0017] Specifically, the needles on the knitting plate and cylinder of the antistatic heat-generating and warm knitted fabric are arranged in a rib pattern. The needle plate has two rows, with the upper needles arranged alternately with high-heel and low-heel needles. Odd-numbered yarns are all knitted on the upper needle plate, and one row of yarn is knitted on the inner layer of the antistatic heat-generating and warm knitted fabric. On the right side, needles are selected to form circles according to the pattern. Even-numbered yarns are not knitted on the upper needle plate, but are knitted on the lower cylinder, meaning all needles in the cylinder knit normally. Two rows of yarns are knitted on the outer layer of the antistatic heat-generating and warm knitted fabric.
[0018] Furthermore, the wool yarn is Merino machine-washable wool yarn. Merino machine-washable wool refers to wool fibers made from fine wool produced by Australian Merino sheep, which undergo a shrink-proof finishing process to damage or passivate the scale layer on the surface of the wool fibers, giving them machine-washable properties.
[0019] Furthermore, the antistatic yarn is graphene-modified PET fiber. The graphene-modified PET fiber is prepared by a blending modification method. First, graphene powder and polyethylene terephthalate are blended and extruded to prepare graphene masterbatch. Then, the graphene masterbatch and PET chips are blended and spun to prepare graphene-modified PET fiber. With a graphene powder mass fraction of 1.0% and a fiber stretch of 3.8 times, the orientation factor of the graphene-modified PET fiber is 0.92, and the volume resistivity is 3.29 × 10⁷ Ω·cm, exhibiting good antistatic properties.
[0020] Furthermore, the padding yarn is made of polyester low-elasticity yarn.
[0021] Example 2 Based on Example 1, the odd-numbered yarn further includes antibacterial nylon yarn, and the heat-generating acrylic yarn and antibacterial nylon yarn are arranged in a 5:1 ratio. The antibacterial nylon is produced by mixing 5% layered nano-silver antibacterial material into nylon 6 masterbatch chips and using blending spinning technology to create antibacterial fibers. These fibers prevent odor generation, have long-lasting antibacterial properties, and have a cross-grooved cross-section that quickly absorbs sweat and transfers it to the fabric surface, keeping the skin dry.
[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.
