Description

Technical Field

[0001] This utility model relates to a fabric, specifically an antistatic cationic single-sided fleece fabric. Background Technology

[0002] Fleece fabric is generally divided into single-sided fleece and double-sided fleece. The side of the fabric that touches the skin is napped, resulting in a delicate and soft feel, making it an ideal fabric for casual wear and sportswear. In dry environments, single-sided fleece fabric is prone to generating static electricity when worn, and static electricity in clothing has a strong dust-attracting effect, which not only soils clothes but also harms health. In addition, single-layer fabric may not provide sufficient warmth when worn in autumn and winter. Therefore, an antistatic cationic single-sided fleece fabric is provided. Utility Model Content

[0003] The purpose of this invention is to provide an antistatic cationic single-sided fleece fabric, which aims to have antistatic function and improve the warmth retention of single-sided fleece fabric.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: an antistatic cationic single-sided fleece fabric, comprising: an antistatic layer and a thermal insulation layer; the antistatic layer is woven from a first warp yarn and a first weft yarn; the first warp yarn is cationic polyester fiber filament, and the first weft yarn is antistatic yarn; the thermal insulation layer is woven from a second warp yarn and a second weft yarn; the second warp yarn is cotton yarn, and the second weft yarn is an acrylic cupro fiber heat-generating blended yarn; the side of the thermal insulation layer away from the antistatic layer is treated with napping.

[0005] Based on the above scheme and as a preferred embodiment of the above scheme: the antistatic yarn is antistatic polyaniline modified wool yarn.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: the fabric structure of the thermal insulation layer is a 2 / 2 right twill weave.

[0007] Based on the above scheme and as a preferred option, the linear density of the cotton yarn is 28 tex, and the linear density of the acrylic cupro fiber heat-generating blended yarn is 15.5 tex × 2.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: a heat insulation layer is further provided between the antistatic layer and the heat insulation layer, and the heat insulation layer is a windproof and antistatic camel hair composite wadding.

[0009] The beneficial effects of this utility model are as follows: Based on the antistatic cationic single-sided fleece fabric of this utility model, the antistatic layer can give the single-sided fleece fabric a certain antistatic function, reducing the static electricity that attracts dust. The acrylic cupro fiber heat-generating blended yarn in the insulation layer can absorb some of the external moisture and convert it into heat, effectively preventing heat loss and the invasion of cold air. The side of the insulation layer that has been napped is softer and fits better against the body, making it less likely for air to flow between the skin and the fabric, so that heat is not easily lost and the insulation effect is better.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] Combination Figure 1 This embodiment provides a detailed description of an antistatic cationic single-sided fleece fabric, comprising: an antistatic layer 1 and a thermal insulation layer 2; the antistatic layer 1 is woven from a first warp yarn and a first weft yarn; the first warp yarn is cationic polyester fiber filament, and the first weft yarn is antistatic yarn; the thermal insulation layer 2 is woven from a second warp yarn and a second weft yarn; the second warp yarn is cotton yarn, and the second weft yarn is an acrylic-copper-ammonia fiber heat-generating blended yarn; the side of the thermal insulation layer 2 away from the antistatic layer 1 is treated with napping.

[0016] The side of the insulation layer 2 that has undergone napping is softer and fits the body better. The napped fabric makes it less likely for air to flow between the skin and the fabric, thus preventing heat loss and resulting in better insulation. At the same time, the fabric is thicker after napping, and the amount of still air in the fabric is increased. This still air forms an insulating layer that prevents heat loss.

[0017] Cationic polyester filament is a polyester product spun by introducing dimethyl isophthalate with polar SO3Na groups into polyester chips. Its appearance is no different from ordinary polyester filament, but due to the ion modification, it not only greatly improves the fiber's color absorption performance, but also reduces crystallinity, making it easier for dye molecules to penetrate. This makes the fiber easy to dye, increases the color absorption rate, and also improves moisture absorption. This fiber ensures that it is cationic and easy to dye, while also increasing the micropores of the fiber, improving the dye uptake rate, breathability, and moisture absorption. It makes the fabric soft, breathable, comfortable, antistatic, and dyeable at normal temperature and pressure.

[0018] Specifically, the antistatic layer 1 and the thermal insulation layer 2 are connected by stitching.

[0019] Furthermore, the antistatic yarn is an antistatic polyaniline-modified wool yarn. The antistatic polyaniline-modified wool yarn is prepared using wool yarn as the base material via in-situ adsorption polymerization. Specifically, the preparation method is as follows: 80% wool-containing wool yarn is pretreated by rinsing it with deionized water and then soaking it in a 10% (w / w) ethanol solution. Insoluble substances and grease on the surface are removed using an ultrasonic cleaner, and the yarn is dried at room temperature. The pretreated wool yarn is then immersed in an aniline solution for 30 minutes to ensure that the aniline monomer reaches a dynamic adsorption equilibrium on the wool fiber surface. An oxidant (ammonium persulfate) is added to initiate polymerization, and the reaction is carried out at room temperature for 24 hours to ensure complete polymerization. The aniline salt solution is 0.2 mol / L, and the ratio of n(aniline):n(ammonium persulfate) is 1:1. After the reaction is complete, the modified wool yarn is removed and washed with ethanol and deionized water until the supernatant is colorless and the solution is neutral. The treated modified wool yarn is then allowed to air dry naturally at room temperature. The conductive polymer polyaniline not only possesses excellent electrochemical and processing properties but is also inexpensive, exhibiting tunable conductivity and reversible doping / dedoping characteristics. The resistivity of the antistatic polyaniline-modified wool yarn can be reduced by 10%. 7 With a resistivity of Ω / cm, it exhibits good antistatic properties, and its resistivity does not change significantly after multiple washes, demonstrating excellent washability and antistatic properties.

[0020] Furthermore, the fabric structure of the insulating layer 2 is a 2 / 2 right-hand twill weave. When making garments from antistatic cationic single-sided fleece fabric, one side of the insulating layer 2 should be close to the human body, ideally close-fitting and soft. Therefore, the number of interlacing times of the warp and weft yarns in the fabric should not be too many. Too many interlacing times will make the fabric stiff, resulting in poor close-fitting effect and easily causing airflow between the skin and the fabric, affecting the warmth retention effect. Therefore, a 2 / 2 right-hand twill weave is selected.

[0021] Furthermore, the linear density of the cotton yarn is 28 tex, and the linear density of the acrylic cupro fiber heat-generating blended yarn is 15.5 tex × 2.

[0022] Specifically, the acrylic cupro fiber heat-generating blended yarn is made of 60% ultrafine denier anti-pilling heat-generating acrylic fiber and 40% cupro fiber. Superfine denier anti-pilling heat-generating acrylic fiber is a moisture-absorbing and heat-generating fiber. Compared with ordinary fibers, it has four special functions: moisture-absorbing and heat-generating function, which refers to the special moisture-absorbing and heat-generating material mixed into the spinning solution of chemical fibers, which can absorb some of the moisture from the outside and convert it into heat; warmth retention function, which can effectively prevent heat loss and the invasion of cold air; moisture permeability function, when the body sweats, the moisture-absorbing and heat-generating fiber can quickly absorb the moisture produced by the body and transfer it to the surface of the fabric, keeping the body dry. The moisture permeability function is achieved by changing the cross-sectional shape of the fiber. The cross-section of the heat-generating acrylic fiber is an irregular polygon, and the fiber surface has micropores and grooves. The micropores give the fiber a good wicking function, and the surface grooves facilitate the transfer of the absorbed moisture to the outer layer of the fabric; it is not easy to pill. Ordinary acrylic fibers are prone to pilling, which affects the appearance and service life of the fabric. The moisture-absorbing and heat-generating acrylic fiber is a superfine denier fiber with an irregular polygonal cross-section and a rough fiber surface. After being spun into yarn, the cohesion between fibers is strong, making it less prone to pilling. Cupro fiber is a cellulose fiber processed from cotton lint. It has good moisture absorption, softness, and skin-friendly properties. Fabrics made from yarns blended with ultra-fine denier anti-pilling acrylic fibers can balance the warmth and comfort of the fabric.

[0023] Example 2

[0024] Based on Embodiment 1, an insulation layer 3 is further provided between the antistatic layer 1 and the thermal insulation layer 2. The insulation layer 3 is a windproof and antistatic camel hair composite wadding. Specifically, the insulation layer 3 is connected to the antistatic layer 1 and the thermal insulation layer 2 by quilting.

[0025] Specifically, camel hair and polyester microfiber are used as the main fibers, combined with stainless steel fiber, cotton and polyester three-dimensional crimped fiber, in a specific ratio of 40 / 20 / 15 / 10 / 10 / 5. Utilizing the low melting point characteristics of ES fiber, the windproof and antistatic camel hair composite wadding is produced through a heat-sealing nonwoven fabric production process. This not only takes into account the excellent warmth retention of camel hair wadding but also improves its windproof and antistatic properties. At the same time, the use of cotton fiber reduces the production cost of the wadding.

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.
