Problems solved by technology

The antibacterial finishing of the fabric is to fix the antibacterial agent on the fiber surface of the fabric through the resin or by adsorption. Most of the antibacterial effect is due to the dissolution of the antibacterial agent from the fiber surface. Some antibacterial agents can chemically interact with the functional groups on the fiber surface. However, its antibacterial property only exists on the surface of the fiber. When the surface fiber falls off, its antibacterial property cannot be replenished, so its antibacterial durability is relatively poor.

Abstract

The invention discloses nano antibacterial bamboo charcoal fibers which comprise the following components in percentage by mass: 0.0005-0.0020% of nano silver microparticles, 7-18% of bamboo charcoal microparticles and the balance of viscose. The nano antibacterial bamboo charcoal fibers have long-acting antibacterial performance and good weaving performance.

Description

technical field [0001] The invention relates to the field of textile fibers, in particular to a nano antibacterial bamboo charcoal fiber. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing are getting higher and higher. Consumers have developed from the initial pursuit of keeping warm to focusing on comfort, beauty, and health. Functional textiles have also emerged as the times require. As early as the first During the First World War, people had already started research on antibacterial textiles. In modern times, in 1996, the acute intestinal disease caused by 0-157 pathogenic E. It has to be said that all of them have caused great damage to human health, and people have also been inspired by it: because human skin is a good nutrient provider for microorganisms in nature, the skin on people's skin Some of the resident bacteria in the body play a role in protecting the skin from pathogenic bacteria. Once the f...
