Description
Technical Field
The invention relates to the technical field of textiles, in particular to a durable antibacterial, anti-mite and antistatic velvet fabric and a production method thereof.
Background
At present, people have strong demand for antibacterial performance of textiles, and put higher demands on the antibacterial performance of the textiles, and consumers pursuing 'durability and comfort' of the functions of the textiles are increasing. In addition, with the enhancement of environmental awareness of people, the environmental requirements of the textile industry are more strict, and the functional textiles develop towards durability and washability.
The textile fabric has two main approaches for realizing the antibacterial function, namely, antibacterial fiber is adopted; firstly, the antibacterial auxiliary agent is adopted for finishing and processing. The mode of finishing by adopting the antibacterial auxiliary agent is a simpler and direct mode, and the cost is relatively low. However, in addition to the common problem of antimicrobial durability, various antimicrobial aids also have problems with each type of antimicrobial aid. The antibacterial fiber includes natural antibacterial fiber, regenerated antibacterial fiber and synthetic antibacterial fiber. The wash durability of the antimicrobial function can be substantially solved by using the antimicrobial fiber, but there is a limitation. Natural antimicrobial fibers are of few species relative to synthetic fibers. The fibrilia is a common natural antibacterial fiber, but the fibrilia is rigid and has poor cohesion; the fabric has the advantages of rough hand feeling, non-slip and comfortable wearing, easy wrinkling, poor drapability and limited application.
For the soft and comfortable hand feeling of the velvet textiles, the velvet textiles are knitted fabrics with structures such as terry or cut velvet, and are mainly used at home in winter at present. Due to the use scenes and technical limitations, the existing velvet fabrics (including face yarns and ground yarns) basically have no antibacterial and anti-mite functions; even if the antibacterial and anti-mite function is realized, the antibacterial and anti-mite function is mainly realized by adding a chemical auxiliary agent through a padding technology, the general antibacterial action can only be maintained for about 10 times, and the durable antibacterial action is difficult to achieve (the antibacterial action is qualified after 50 times of water washing). Compared with light and thin textiles such as silk cloth and the like, the velvet fabric has the problems of being troublesome to wash and dry, not easy to dry and the like, so people usually have relatively few washing times, and are more easy to cause breeding of bacteria and mites. The washing frequency of the velvet fabric is reduced due to the trouble of washing the velvet fabric, so that bacteria and mites are easy to breed on the velvet fabric, and a plurality of hidden dangers in the aspect of sanitation are brought.

blending natural mineral antibacterial short fibers and other short fibers into antibacterial composite yarns, and then knitting to obtain antibacterial grey cloth with a looped pile or cut pile structure; the natural mineral antibacterial short fiber is prepared by acquiring positively charged metal ions from natural minerals and then spinning the positively charged metal ions with a chemical fiber carrier or a regenerated fiber carrier in a pressure spinning mode, wherein the positively charged metal ions account for 0.5 to 2wt% of the fiber carrier; the natural mineral antibacterial short fibers account for 3-10% of the mass of the antibacterial gray fabric;
and dyeing and post-finishing the antibacterial gray fabric to obtain the durable antibacterial, anti-mite and antistatic velvet fabric.
9. The production method according to any one of claims 5 to 8, wherein the dyeing is carried out by a high temperature and high pressure dyeing process using a disperse dye.
10. The production method according to any one of claims 5 to 8, characterized in that the post-finishing process comprises the steps of napping, carding, shearing, pilling, tentering and setting in sequence to obtain the finished velvet fabric.
