Abstract

The invention discloses an antibacterial yarn, and belongs to the technical field of textile. The yarn is prepared from two or more than two of synthetic quaternary ammonium type, quaternary phosphine salt type and silver-loaded cotton fiber type antibacterial fibers in patents of CN101879466B, CN102720057B, CN103266473B and CN103835124B, one or more of cotton, viscose, tencel, dacron, chinlon, modal and soybean fiber blended fibers, and bamboo charcoal fibers by processes of opening picking, combining, cotton carding, drawing, roving, spinning and the like. A fabric made of the antibacterial yarn resists staphylococcus aureus, escherichia coli and pseudomonas aeruginosa, and is good in antibacterial property; and even if the fabric is cleaned by fifty times, the antibacterial property of the fabric can be maintained and regenerated. The antibacterial fabric not only has good antibacterial property, but also is good in spinning property, light in weight and excellent in mechanical strength; series of products such as antibacterial socks and antibacterial underwear can be developed; and skin adaptability, hygroscopicity, degree of comfort and the like are improved.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a chemically grafted antibacterial fiber yarn. Background technique [0002] In my country, with the improvement of people's living standards and hygiene awareness, the demand for antibacterial fabrics is increasing. Antibacterial fabrics can block the contact of various harmful bacteria with the human body and kill bacteria. At present, antibacterial fibers are mainly prepared by blending spinning method, composite blending method, post-finishing method, and graft modification method. Usually, it is difficult to use antibacterial fiber alone to prepare civil and medical fabrics with spinnability, hygroscopicity, air permeability, antistatic property, anti-pilling property, skin-friendly property, etc., so that the benefit of antibacterial fiber fabrics to the people and the society is limited. . At present, there are the following reports about antibacterial yarn and fiber: ...
