Description

Technical Field

[0001] This invention belongs to the field of knitted fabric technology, specifically relating to a multifunctional weft-knitted fabric with antibacterial, deodorizing, mite-proof, and mosquito-repellent functions formed by functional yarns containing natural mineral materials, and its preparation method. Background Technology

[0002] Antibacterial textiles possess bactericidal and bacteriostatic properties, benefiting people's health. On one hand, for the user's health, antibacterial textiles prevent the combination of human skin, sweat, and other metabolic substances with the fabric, thus preventing the growth of numerous microorganisms and reducing the risk of infectious diseases caused by pathogens. They also reduce odors produced by microbial growth. On the other hand, for the textiles themselves, their antibacterial function protects the fabric, reducing microbial damage during use, extending the textile's lifespan, and increasing its value. Therefore, reliable and safe antibacterial textiles are highly favored by the market and are already used in sportswear, home textiles, and other fields to enhance the hygiene of daily wear.

[0003] In existing technologies, antibacterial textiles can be directly woven from fibers with antibacterial functions, such as natural antibacterial fibers and artificial antibacterial fibers; or antibacterial agents can be used in the finishing process of the fabric to give it antibacterial properties.

[0004] Natural antibacterial fibers originate from nature and have a unique linear macromolecular structure. They contain natural antibacterial substances that can inhibit and kill pathogenic microorganisms. Common natural antibacterial fibers include hemp, bamboo, kapok, horned melon, chitin, chitosan, and seaweed fiber.

[0005] Artificial antibacterial fibers are a type of fiber that acquires antibacterial function by adding antibacterial agents during the spinning process. Common processing methods include blending spinning, composite spinning, chemical grafting modification, ion exchange, and wet spinning. The added antibacterial agents can generally be classified into three categories: natural antibacterial agents, organic antibacterial agents, and inorganic antibacterial agents. Examples include: viscose-modified fibers, which are prepared by adding antibacterial components from plants such as Artemisia argyi, Artemisia argyi, Aloe vera, Isatis indigotica, tea, mint, and Coral mesona; polyester and nylon, which can be prepared by adding metal ions such as silver ions, trace amounts of copper ions, and zinc ions; as well as graphene, bamboo charcoal fibers, Taiji stone fibers with added natural silica quartz minerals, and bio-based phytochemicals. It incorporates antibacterial fibers such as nylon and polyester. Fabrics made from antibacterial functional fibers have the characteristics of long-lasting antibacterial effect and good washability, but artificial antibacterial fibers are technically difficult to produce and are relatively expensive.

[0006] Antibacterial textiles produced using finishing processes also employ antibacterial agents. During the finishing process, these agents are applied to the fabric through methods such as padding, impregnation, coating, and spraying, imparting antibacterial properties. These textiles have low processing costs but are not washable.

[0007] Regarding the anti-mite function, there are no specific textile examples in the publicly available information that directly mention its combination with antibacterial and deodorizing properties. However, some antibacterial textiles usually indirectly inhibit the environment in which mites breed, thus achieving broad-spectrum protection of antibacterial, deodorizing, and anti-mite properties in principle through similar technical approaches.

[0008] Current methods for preparing mosquito-repellent textiles primarily involve combining mosquito repellents or finishing agents with fabrics to give them the function of repelling or killing mosquitoes. Common preparation methods include surface finishing, blending spinning, and soaking processes. Existing data do not explicitly report the integration of mosquito repellent and antibacterial / deodorizing functions, and there are no reports of textiles that simultaneously integrate four functions: antibacterial, deodorizing, anti-mite, and mosquito repellent.

[0009] The fiber is a modified polyester fiber with added nano- to micron-sized natural mineral materials from Queensland, Australia. Because this natural mineral material is porous, has low density, high specific surface area, good adsorption, stable chemical properties, high melting point and good thermal stability, when added to polyester fiber in a certain proportion, it has good adsorption and ion exchange performance.

[0020] The preparation method provided by this invention may also have the following characteristic: the basis weight of the raw fabric is 204 g / m². 2 .

[0021] Compared with the prior art, the present invention has the following advantages: 1. The fabric has multiple functions including antibacterial, deodorizing, mite-repellent, and mosquito-repellent properties, and its functions are well maintained and durable.

[0022] Dimineral fiber is a modified polyester fiber with added nano-micron-sized natural minerals from Queensland, Australia. Its main component is amorphous silica. It has porous, high specific surface area and nano-scale sharp spikes. Its multifunctionality depends on the physical structure and microenvironment regulation ability. The core principle is as follows: (1) Antibacterial mechanism, achieved through the synergistic effect of two mechanisms: First, the sharp spikes of mineral nano-scale physically pierce the cell wall / membrane of microorganisms, causing leakage of contents, osmotic pressure imbalance and lysis. Pure physical action has no drug resistance; Second, its high hygroscopic properties quickly adsorb the moisture on the surface and around the microorganisms, forming a dry microenvironment, inhibiting metabolic activity. It is more effective in inhibiting hygroscopic microorganisms in high humidity environments; (2) Deodorizing mechanism, with the synergistic effect of porous structure and surface chemical properties: The core is that the pore size of the porous skeleton matches the diameter of the odor molecules. Through van der Waals forces and electrostatic interactions, it achieves "molecular sieve" physical adsorption; The surface silanol groups can bear the negative Photocatalytic material, photoexcitation generates active species to oxidize and decompose organic odors into harmless substances; porous structure simultaneously stabilizes catalytic components, promotes electron transfer, and improves decomposition efficiency; (3) Anti-mite mechanism, based on three mechanisms: First, sharp micro-thorns pierce the wax layer and chitinous exoskeleton of dust mites, causing body fluid leakage, dehydration and death, non-toxic and without resistance; Second, efficient moisture absorption reduces local humidity to below 50%, destroying the survival requirement of dust mites at 60%-80% relative humidity, inhibiting metabolism and reproduction; Third, forming a physical barrier to block egg laying, depriving the eggs of water for development, and blocking the life cycle; (4) Mosquito repellent mechanism, which is the same as the anti-mite mechanism, with the two mechanisms working together: First, nano-sharp thorns pierce the wax layer of mosquito body surface, destroying the lipid barrier and causing body fluid leakage and osmotic pressure imbalance; Second, high moisture absorption characteristics quickly remove water from the mosquito body surface, and when body fluid loss exceeds 10%, physiological function collapses, pure physical action without resistance risk.

[0023] The antibacterial, deodorizing, anti-mite, and mosquito-repellent functions of the fabric of this invention originate from 4.5% natural mineral microparticles in the 30% by weight of the modified polyester fiber containing mineral extract. These natural mineral microparticles are porous (porosity up to 80-90%, with strong adsorption and ion exchange properties), have low density (0.3-0.7 g / cm³, making the material lightweight), high specific surface area (40-65 m² / g, capable of adsorbing a large amount of substances), good adsorption capacity (absorbing 2-4 times its own weight in water, and also adsorbing and decomposing some chemical substances), stable chemical properties (insoluble in strong acid solutions, soluble in strong alkali solutions), high melting point (1650-1750°C), and good thermal stability. Therefore, when this natural mineral material is added to the polyester fiber at a mass ratio of 4.5%, and the modified polyester fiber accounts for 30% of the fabric's mass ratio, test results show excellent antibacterial and deodorizing functions, as well as anti-mite and mosquito-repellent effects. This function is entirely derived from mineral extract. Made of modified polyester fiber, the fabric has no added functional finishing, and its functionality will not decline with each wash, thus maintaining its functionality well and ensuring its durability.

[0024] 2. The fabric has a good feel and is comfortable to wear.

[0025] The antibacterial, deodorizing, mite-proof, and mosquito-repellent functions of the fabric of this invention originate from the 30% of the fiber fabric made of modified polyester fiber, and no functional coatings are added during the finishing process, thus there is no loss of hand feel due to functional finishing. The fabric uses a blended yarn of 40S cotton / modified polyester / lyocell (50 / 30 / 20), resulting in a smooth surface. The 50% cotton and 20% lyocell fiber by weight enhance the overall moisture absorption and softness of the fabric, making it comfortable to wear next to the skin. Combined with the weft plain knitting structure and the fabric singeing, light wool processing, and softening finishing processes during the finishing process, the fabric is given characteristics of being lightweight, having a smooth and clean surface, being soft, and having a good touch. The knitted loop structure has a large number of loops themselves and between loops, giving the fabric good breathability and moisture permeability, resulting in better wearing comfort.

[0026] 3. The fabric has good elasticity and is easy to care for.

[0027] The fabric of this invention uses a weft-knitted plain knit structure woven with 40S blended yarn and 20D spandex, woven on a 28-gauge single-sided circular knitting machine. The spandex content in the finished fabric is 5%. It not only provides the elasticity of the knitted loop structure and single-sided weft-knit structure, but also gives the spandex-woven elastic fabric a moderate elasticity. The fabric is not only elastic, but also has good recovery and shape retention after washing, making it easy to wear and care for after washing. Detailed Implementation
