Description

Multifunctional weft-knitted fabric with antibacterial, deodorizing, mite-preventing and mosquito-repelling functions and preparation method thereof Technical Field The invention belongs to the technical field of knitted fabrics, and particularly relates to a multifunctional weft-knitted fabric with antibacterial, deodorizing, mite-preventing and mosquito-repellent functions and formed by using functional yarns containing natural mineral materials and a preparation method thereof. Background The antibacterial textile has the functions of sterilization and bacteriostasis, and is beneficial to the health life of people. On one hand, for the health of a user, the antibacterial textile can prevent metabolic substances such as cortex and sweat of a human body and the like from being combined with the textile to breed a large amount of microorganisms, reduce the risk of pathogenic microorganism infection diseases, and reduce peculiar smell generated by microorganism breeding, and on the other hand, for the textile, the antibacterial textile can also protect the textile, reduce the microorganism erosion of the textile in the use process, prolong the service life of the textile and improve the use value. Therefore, antibacterial textiles with reliable quality and high safety are popular in the market, and are applied to the fields of sports clothes, household textiles and the like to enhance the sanitation of daily wear. In the prior art, the antibacterial textile can be directly woven by adopting fibers with antibacterial functions, such as natural antibacterial fibers and artificial antibacterial fibers, or can be subjected to antibacterial finishing by using an antibacterial agent in the after-finishing process of the fabric, so that the antibacterial performance of the fabric is obtained. The natural antibacterial fiber is derived from nature, has unique linear macromolecular structure, contains natural antibacterial substances, can inhibit and kill pathogenic microorganisms, and is commonly selected from hemp, bamboo, kapok, calotropis gigantea, chitin, chitosan, alginate fiber and the like. The artificial antibacterial fiber is one fiber with antibacterial function obtained through adding antibacterial agent during spinning, and common processing methods include blend spinning process, composite spinning process, chemical grafting modification process, ion exchange process, wet spinning process, etc. The added antibacterial agents can be generally classified into natural antibacterial agents, organic antibacterial agents and inorganic antibacterial agents. Such as viscose modified fiber prepared by adding antibacterial components such as herba Artemisiae Argyi, aloe, radix Isatidis, folium Camelliae sinensis, herba Menthae, herba Pileae Scriptae, etc., antibacterial fiber prepared by adding silver ion, copper ion, zinc ion, etc., graphene, bamboo charcoal fiber, taiji stone fiber added with natural silica quartz ore, and biobased gramineous, etcAntibacterial fibers such as nylon, terylene and the like are combined. The fabric prepared from the antibacterial functional fibers has the characteristics of lasting antibacterial effect and good washing fastness, but the artificial antibacterial fibers are high in technical difficulty and high in price. The antibacterial agent is also used for producing antibacterial textiles by a fabric after-finishing method, and is attached to the fabrics in the modes of padding, dipping, coating, spraying and the like in the after-finishing process of the textiles, so that the antibacterial performance of the textiles is endowed. The textile has low processing cost but is not wash-resistant. With regard to the mite-proof function, the specific textile case combined with antibacterial deodorizing is not directly mentioned in the publication, but part of the antibacterial function textile usually indirectly inhibits the environment of mite breeding, and the antibacterial, deodorizing and mite-proof broad-spectrum protection is realized in principle through similar technical paths. The existing mosquito-repellent textile is prepared by combining a mosquito repellent or a mosquito-repellent finishing agent with a textile, so that the mosquito-repellent textile has the function of repelling or killing mosquitoes. Common preparation methods include a surface finishing method, a blending spinning method, a soaking process and the like. The integration of the mosquito repellent and the antibacterial deodorizing function is not explicitly reported in the prior art, and the textile integrating the four functions of antibacterial, deodorizing, mite preventing and mosquito repellent is not reported. The fiber is a modified polyester fiber added with nano-micron grade natural mineral materials from Australian Kunsland, and has the advantages of porous, low density, high specific surface area, good adsorptivity, stable chemical property, high melting point and good thermal stability, and when
