Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of textile fabrics, and specifically relates to a multifunctional fabric with moisture absorption, sweat wicking, quick drying, antibacterial and warmth retention and a preparation method thereof. BACKGROUND

[0002] In the textile industry, the innovation and functional development of fabrics have always been the focus of attention. With the continuous improvement of people's demand for comfort, health care and functionality, multifunctional fabrics with moisture absorption, sweat wicking, quick drying, antibacterial and warmth retention emerge as the times require, bringing new technical prospects to the field of textiles. Traditionally, moisture-conducting fabrics are widely used in sports wear, outdoor equipment and other fields to improve the comfort of wearers. However, with the increasing demand for antibacterial properties, the market demand for fabrics with both moisture-conducting and antibacterial properties has also increased. Antibacterial properties not only help to reduce the growth of bacteria on the surface of the fabric, but also effectively inhibit the generation of odor, making the fabric more suitable for daily life, sports and medical use. In view of this market trend, multifunctional fabrics with moisture absorption, sweat wicking, quick drying, antibacterial and warmth retention emerge as the times require. Such fabrics combine moisture-conducting technology, which can quickly absorb and remove body sweat, improving the comfort of wearers; at the same time, the antibacterial treatment effectively inhibits the reproduction of microorganisms on the surface of the fabric, providing additional health protection. Such fabrics not only play a role in sports and outdoor activities, but also become an ideal choice in daily life, meeting the multiple needs of modern people for comfort, health and functional diversity.

[0003] Chinese patent CN107034692A discloses a one-way moisture-conducting fabric and its production process, the moisture-conducting fabric comprises three layers, the inner layer is polyester fiber, the middle layer is hydrophilic polyester fiber, and the outer layer is cotton fiber, and its production process comprises the following steps: weaving embryo, embryo inspection, cloth sewing head, dyeing and finishing, dehydration, drying cloth, picking and combing, shearing, finished product shaping, and finished product inspection. The one-way moisture-conducting fabric produced by the patent can bring the moisture absorbed by the base shirt to the surface of the coat, keep the inner layer close to the body dry, effectively improve the comfort during human movement, has good one-way moisture-conducting performance, does not use waterproof additives in the post-finishing process, is beneficial to environmental protection, has the characteristics of soft hand feeling, comfortable and breathable, and low cost. Chinese patent CN106012538A discloses a production method of a moisture-absorbing and quick-drying one-way moisture-conducting double-layer fabric, comprising the following steps: first, cationic polyester yarn and polyester filament are used to weave a double-layer fabric gray cloth, then the double-layer fabric gray cloth is treated with modified refining agent LS01, ice acetic acid is added, washed, and finally subjected to dyeing and reduction cleaning and other post-treatment, so that the double-layer fabric has the functions of moisture absorption and quick drying and one-way moisture conduction. The fabric produced by the patent does not need to add other moisture-absorbing and quick-drying or one-way moisture-conducting moisture-wicking additives, is comfortable and breathable to wear, the production process is environmentally friendly, and the production cost is reduced. However, the moisture-conducting fabric disclosed in the above patent has relatively single function and cannot meet the current market demand for multifunctional fabric, such as antibacterial, warm-keeping, antistatic, wear-resistant, etc. SUMMARY

[0004] To achieve the above-mentioned purpose, the present application provides a multifunctional fabric with moisture-wicking, quick-drying, antibacterial and warm-keeping functions, which is composed of a surface layer and an inner layer. The inner layer is made of core-spun yarn made of Lycra spandex and volcanic clay nylon, the surface layer is made of Thermolite fiber and Nilit Softex fiber, and 8 yarns are used for one cycle of weaving, so that the fabric has excellent properties such as lightness, softness, moisture absorption, breathability, antibacterial and warm-keeping. The present application also provides a preparation method of the multifunctional fabric with moisture-wicking, quick-drying, antibacterial and warm-keeping functions.

[0005] The technical scheme adopted by the present application is:

[0006] A multifunctional fabric with moisture-wicking, quick-drying, antibacterial and warm-keeping functions, which is composed of a surface layer and an inner layer.

[0008] The surface layer material adopted by the present application is composed of Thermolite fibers and Nilit Softex fibers. Among them, the Thermolite fiber is a hollow fiber imitating polar bear down, which builds an air protection layer through O-shaped hollow structure. This design not only effectively insulates cold air, but also quickly removes body surface moisture, providing the wearer with a warm, dry, comfortable and light wearing experience. The ingenious design of the hollow structure reduces the weight of the fiber, making it lightweight while keeping warm, meeting the extreme demand for body temperature safety protection in extremely cold environments; the Nilit Softex fiber adopts a T-shaped cross-sectional design, increasing the fiber surface area and optimizing the micro-channels generated by the cross-section of the moisture-wicking. This design allows moisture to be removed from the fiber surface more quickly. The Nilit Softex fiber fabric is soft, comfortable, breathable and moisture-wicking, with excellent quick-drying properties, making the wearer feel a more delicate fabric touch. The Thermolite and Nilit Softex fibers selected by the present application are ingeniously combined to provide the surface layer material with excellent moisture-wicking and warmth retention performance and comfort, meeting the multiple demands for clothing functions in different environmental conditions.

[0009] Preferably, the weight percentage of the inner layer material is 20-50wt%, the inner layer material is a core-spun yarn made of 10-30wt% core yarn and 70-90wt% covering yarn, and the covering yarn is wrapped around the surface of the core yarn; the core yarn is Lycra spandex, and the covering yarn is volcanic clay nylon 6.

[0010] The inner layer material adopted by the present application is a core-spun yarn made of Lycra spandex and volcanic clay nylon 6. Among them, the volcanic clay nylon 6 has good moisture absorption, which helps to absorb and regulate moisture, keeping the wearer comfortable, and the contained volcanic clay nanoparticles can endow the nylon 6 with certain antibacterial properties, which helps to inhibit microbial growth and keep the fabric clean and sanitary; Lycra spandex has excellent stretch and rebound properties, which can improve the durability and comfort of the fabric. This core-spun yarn fully utilizes the advantages of both by wrapping the high-hygroscopicity volcanic clay nylon 6 around the surface of Lycra spandex, providing the inner layer fabric with high moisture absorption and antibacterial properties, while ensuring the balance between comfort and durability, which can improve the moisture absorption of the overall fabric, help to sweat and keep the wearer comfortable, the antibacterial property of the volcanic clay nylon 6 can prevent bacteria from growing to some extent, keep the fabric clean, and the elasticity of Lycra spandex combined with the durability of the volcanic clay nylon 6 makes the core-spun yarn provide comfortable elasticity and sufficient durability during wearing.

[0011] Preferably, the preparation method of the core-spun yarn is as follows: the core yarn is fed into the roller, subjected to 2.5-3.5 times pre-drafting, and fed into the front roller nip through the guide eye; the covering yarn passes through the back roller and the middle roller to converge with the core yarn at the front roller, and forms the core-spun yarn under the twisting action of the ring spinning machine.

Compared with examples 6-7, the Thermolite and Nilit Softex fibers used in the surface layer raw materials of examples 1-3 are ingeniously combined to provide excellent moisture conductivity, warmth retention and comfort for the surface layer. The Thermolite fiber is a hollow fiber imitating polar bear down, which not only effectively insulates cold air, but also quickly removes body surface moisture, providing a warm, dry, comfortable and light wearing experience for the wearer. The T-shaped cross-section design of Nilit Softex fiber increases the fiber surface area, optimizes the micro-channels generated by the moisture-wicking cross-section, so that the moisture can be quickly removed from the fiber surface. Compared with examples 1-2, 4-5, in the process of dipping the blended yarn with the modified finishing liquid, the self-made antibacterial and antistatic finishing agent (palmitamide grafted nano zinc oxide) is uniformly attached to the fiber surface of the yarn, forming a continuous functional nano layer, and at the same time, polyethylene glycol 400 and chitosan play a role in stabilizing the nano layer. This optimized modified finishing liquid further improves the antistatic property and durable antibacterial property of the fabric on the basis of the original nano zinc oxide.
