Problems solved by technology

[0003] At present, although there are also antibacterial and antiviral effects on textiles through post-finishing processing methods on the market, on the one hand, their application is mainly through silver ions, cupro ammonia fibers, etc., which are not only expensive but also low in reliability. The post-effect declines or even loses the effect, and it is difficult to achieve and maintain the expected anti-virus function for a long time. On the other hand, the post-finishing processing methods on the market also have the problems of unsatisfactory finishing effect, low comfort and low durability. Effective anti-bacteria and virus finishing methods are very important to control bacteria and viruses at an early stage

Abstract

The invention discloses an antibacterial finishing agent, a finishing method and a fabric product. The antibacterial finishing agent is used for finishing a fabric; and the antibacterial finishing agent is obtained by mixing a waterborne polyurethane emulsion, an organic silicon foaming agent, charged diatomite, an organic silicon coupling agent and at least one auxiliary agent, wherein the hydroxyl content of the charged diatomite is 0.10-0.28 mmol / g, and / or the porosity is 70-90%. According to the antibacterial finishing agent provided by the invention, bacteria and viruses can be effectively inactivated, the transmission of the viruses can be blocked, and when the antibacterial finishing agent is finished on the fabric, the antibacterial finishing agent is strong in adhesive force and high in persistence and effectively protects human health.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to an antibacterial finishing agent, a finishing method and fabric products. Background technique [0002] In order to ensure the performance of textiles, they can be finished with various functions, such as waterproof and water-repellent finishing, flame-retardant finishing, antistatic finishing, softening finishing, and anti-wrinkle finishing. Anti-viral finishing is also very necessary to inhibit the spread of bacteria and viruses. [0003] At present, although there are also antibacterial and antiviral effects on textiles through post-finishing processing methods on the market, on the one hand, their application is mainly through silver ions, cupro ammonia fibers, etc., which are not only expensive but also low in reliability. After the effect declines or even loses the effect, it is difficult to achieve and maintain the expected anti-virus function for a long time...
