A warm and breathable close-fitting clothing fabric and its manufacturing process

Abstract

This invention relates to the field of clothing fabric technology, specifically to a warm and breathable close-fitting clothing fabric and its preparation process, including the following steps: Step (1) Spinning: PET fibers and PBT fibers with a cross-shaped hollow cross section are combined, twisted, and set to obtain yarn; Step (2) Weaving: The yarn is spun to form a fabric; Step (3) Dyeing and finishing: The fabric is dyed and finished to obtain the clothing fabric. In this invention, yarn and fabric are obtained sequentially through processes such as combining and knitting. The cross sections of PET fibers and PBT fibers are "cross" shaped hollow. By combining two-component irregular cross-section yarns, a larger surface area can be obtained. Through the grooves formed by their crosses, the moisture-wicking and drainage effects are achieved. This allows the fabric to quickly absorb moisture and sweat from the skin surface and release it to the outer layer for evaporation, keeping the body dry and comfortable. This achieves the breathability, moisture absorption and quick-drying, warmth and perspiration-wicking capabilities of the clothing fabric.

Description

Technical Field

[0001] This invention relates to the field of clothing fabric technology, specifically to a warm and breathable close-fitting clothing fabric and its preparation process. Background Technology

[0002] T-shirts are an essential summer item, and the current market mainstream consists of cotton T-shirts or quick-drying synthetic fiber sports T-shirts. Cotton T-shirts offer the comfort and skin-friendliness of natural fibers, as well as good moisture absorption. However, their quick-drying effect is undeniably less than ideal. Moisture produced by the body cannot be effectively wicked away during wear, leading to a sticky feeling and discomfort, ultimately affecting the wearing experience. Furthermore, residual moisture on the clothing, upon contact with the skin, increases body dampness and coldness, hindering heat retention. Synthetic fiber quick-drying materials achieve their moisture-wicking and quick-drying effects through fiber or finishing processes, maintaining quick-drying properties and keeping the skin dry during exercise. However, their drawbacks include a relatively dry feel and poor skin-friendliness. Therefore, we propose a warm and breathable close-fitting clothing fabric and its manufacturing process. Summary of the Invention

[0003] The purpose of this invention is to provide a warm and breathable close-fitting clothing fabric and its manufacturing process to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a manufacturing process for a warm and breathable close-fitting clothing fabric, comprising the following processes:

[0005] Step (1) Spinning: Combine PET fibers and PBT fibers with cross-shaped hollow cross sections, twist them, and set them to obtain yarn;

[0006] Step (2) Weaving: The yarn obtained in step (1) is woven to form a fabric;

[0007] Step (3) Dyeing and finishing: Dye and finish the fabric obtained in step (2) to obtain clothing fabric.

[0008] Furthermore, in step (1), the yarn specification is 100D / 96F;

[0009] In a single yarn, there are 48 PET fibers and 48 PBT fibers.

[0010] Furthermore, in step (2), the weaving is done using a circular knitting machine with a specification of 34 inches and 32G.

[0011] In the above technical solution, 100% polyester functional yarn is used, and the yarn and fabric are produced sequentially through processes such as yarn doubling and knitting. The yarn doubling maintains stable nodes and tension, giving the yarn excellent spinnability. PET and PBT fibers have a cross-shaped hollow structure. By using a combination of two-component irregularly shaped cross-section yarns, a large surface area can be obtained. The grooves formed by the cross-section achieve moisture wicking and drainage, enabling the fabric to quickly absorb moisture and sweat from the skin's surface and release it to the outer layer for evaporation, keeping the body dry and comfortable. This results in breathable, moisture-wicking, quick-drying, warm, and perspiration-wicking capabilities in the garment fabric.

[0012] The combination of yarn structure and components, through PBT fibers, imparts a superior cotton-like feel to the fabric. Utilizing a high-speed circular knitting machine with a denser needle plate than conventional weaves, the fabric exhibits a finer texture and a velvety sheen reminiscent of natural cotton. It also possesses excellent moisture absorption and quick-drying properties, is colorfast, does not easily deform, is easy to wash, and simple to dry, making it suitable for commuting and travel clothing. The fabric produced in this invention can be used to manufacture standard-pattern T-shirts, and designs can be incorporated based on these patterns to suit various occasions.

[0013] Furthermore, in step (3), the dyeing process is as follows: dyeing temperature 120-130℃, dyeing time 60-70 minutes, liquor ratio 1:(50-100), and static cooling after dyeing; two dips and two nips, with a liquor carryover rate of 40-50%;

[0014] Immerse in a color-fixing solution, repeat immersion and rolling, with a liquid retention rate of 30%, and dry at 80-100℃.

[0015] The dyeing agent comprises 1–4 wt% dye and 0.5–4 wt% auxiliaries; the dye is selected from one or more of Reactive Blue MB, Reactive Red 195, Disperse Blue 79, Disperse Blue 2B, Disperse Red 195, and Disperse Red 3B.

[0016] The additives include sodium dodecylbenzenesulfonate (LAS), dodecyl dimethyl betaine (BS12), fatty acid polyoxyethylene ether (AEO9), and dodecyl trimethylammonium chloride (1231).

[0017] The fixing solution contains 20 g / L sodium carbonate and 200 g / L sodium sulfate.

[0018] In the above technical solution, the different shrinkage rates of PET and PBT fibers during the dyeing process cause local fluctuations in the fiber count, giving the fabric a good cotton feel and matte finish. The addition of auxiliaries and dyes maintains the fabric's uniform coloring in the dyeing vat while preserving its smoothness. Simultaneously, the cross-section of the fibers increases the fabric's surface area, enhancing its water-wicking ability. This, in conjunction with subsequent finishing processes, improves the hydrophilicity of the resulting garment fabric, promoting the rapid wicking and evaporation of sweat produced by the human body.

[0019] Furthermore, in step (3), the finishing process is as follows: the fabric is left to stand under constant temperature and humidity for 10 to 12 hours; the constant temperature and humidity conditions are: temperature 18 to 25°C, relative humidity 60 to 67%;

[0020] Immerse in finishing agent at room temperature for 18-25 minutes; immersion bath ratio is 1:(180-200); one immersion and one roll, with a roll-off rate of 28-32%, and bake at 100-105℃ for 10-20 minutes.

[0021] Further, after finishing, it is baked at high temperature for shaping. The process conditions are: baking temperature 150-180℃, baking time 20-45 minutes.

[0022] Furthermore, the finishing agent is prepared by the following process:

[0023] Mix poly(methylhydrosiloxane) and vinylpyrrolidone, heat to 80-85°C, add chloroplatinic acid, raise the temperature to 110-120°C, and maintain the temperature for 60-90 min.

[0024] Allyl polyethylene glycol and vinyl silk fibroin were added, and the reaction was continued for 2-3 hours to obtain modified polyether; the temperature was lowered to 80-90℃, and the mixture was dried under vacuum at a vacuum degree of -0.05 to -0.08 MPa for 60-90 minutes.

[0025] Dimethyl terephthalate was added, the temperature was raised to 160-190°C, and the reaction was maintained for 2 hours. The mixture was then distilled under reduced pressure to obtain a hydrophilic agent. After cooling to room temperature, a crosslinking agent and glacial acetic acid were added, and the mixture was stirred at high speed while deionized water was added to obtain a finishing agent.

[0026] Furthermore, the finishing agent comprises the following components by weight: 100 parts poly(methylhydrosiloxane), 20-42 parts vinylpyrrolidone, 0.0010-0.0013 parts chloroplatinic acid, 80-108 parts allyl polyethylene glycol, 8.2-15.4 parts vinyl silk fibroin, 8-11 parts dimethyl terephthalate, 3.0-4.5 parts crosslinking agent, and 6.0-7.8 parts glacial acetic acid;

[0027] The crosslinking agent is ethylene glycol glycidyl ether; the solid content of the finishing agent is 10-12%.

[0028] Poly(methylhydrosiloxane): sourced from Gaide Chemicals;

[0029] Allyl polyethylene glycol: Allyl polyethylene glycol 1000, sourced from Jiangsu Haian Petrochemical Plant.

[0030] Furthermore, vinyl silk fibroin is obtained by the following process:

[0031] Mix silk fibroin solution and methacrylic anhydride, adjust the pH of the system to 7-8 at 0-5℃, and react for 6 hours; dialyze to obtain vinyl silk fibroin;

[0032] The mass ratio of silk fibroin to methacrylic anhydride is 100:(5.2~17.6).

[0033] The mass concentration of the silk fibroin solution is 10–20 wt%.

[0034] Silk fibroin: sourced from Zhongxin Chuangwei Biotechnology Co., Ltd.

[0035] In the above technical solution, under the action of platinum catalyst platinum chloride, the hydrogen in poly(methylhydrosiloxane) reacts with the double bonds in vinylpyrrolidone, allyl polyethylene glycol, and vinyl silk fibroin, introducing pyrrolidone structures, polyether molecular chains, and silk fibroin molecules into the siloxane molecular structure. Polysiloxane has low surface tension, easily spreads on the surface of polyester fibers, and has good film-forming properties, giving the finished fabric (the made clothing fabric) a unique hand feel. Amino-containing organosilicon is a commonly used reagent, which can impart good smoothness to polyester after finishing. However, under the influence of light and heat, the primary and secondary amine groups on its molecular chain are easily oxidized to form C=N chromophores. The hydrophilic agent with pyrrolidone groups has amide functional groups on its side groups. The strong electron-withdrawing property of the organic acyl group reduces the electron cloud density on the nitrogen atom, making the amino group less susceptible to oxidation. This results in the finished fabric (the made clothing fabric) having good moisture absorption and breathability, softness, and anti-yellowing capabilities. The introduction of polyether chains increases the hydrophilicity of the prepared hydrophilic agent. The growth of the hydrophilic agent's side chains and the presence of hydrophilic polyether groups in the molecular structure improve the moisture absorption of the finished fabric (the resulting garment fabric), enhancing its breathability, quick-drying properties, and warmth-wicking capabilities. The introduction of silk fibroin further improves the fabric's hydrophilicity, enhancing its moisture absorption, quick-drying properties, and breathability, while also improving its hand feel, washability, abrasion resistance, skin-friendliness, and comfort. Dimethyl terephthalate is then added, undergoing transesterification with the product obtained from the above reaction to form polyester polyether segments, resulting in a hydrophilic agent that imparts excellent hydrophilicity, washability, and abrasion resistance to the fabric. During the application of finishing agents, the crosslinking agent ethylene glycol glycidyl ether reacts with the hydrophilic agent under the processing conditions, further improving the garment fabric's washability and maintaining its moisture-wicking, breathability, and warmth-wicking capabilities.

The clothing fabrics obtained in Comparative Examples 1-3 showed deterioration in the data of water droplet diffusion time, moisture residue, capillary height, hand feel grade, and pilling grade before and after washing. It can be seen that the setting of the finishing agent components and process of the present invention can promote the improvement of the moisture absorption, quick drying, hydrophilicity, comfort, and water washing and abrasion resistance of the clothing fabric.
