Abstract

The invention discloses a preparation method of nano-bamboo charcoal antibacterial fibers for pets, and relates to the technical field of textiles. According to the method, modified starch and nano-silver are organically combined, so that the nano-silver cannot be easily aggregated, dissolution and dispersibility of the nano-silver in carrier slices are improved, and the nano-silver has good antibacterial effects. A prepared active addition agent has adhesive property and more active groups, the nano-silver is connected with the fibers through a chemical bond, and the adhesiveness of the nano-silver on the fibers is improved, so that the antimicrobial durability of the fibers is prolonged. The prepared bamboo charcoal fibers have excellent moisture absorption performance, abrasion resistance and excellent antibacterial performance and are applicable to making of pet clothes, and bamboo charcoal is provided with renewable resources, wide in source, economical and environmentally friendly.

Description

Technical field: [0001] The invention relates to the technical field of textiles, in particular to a preparation method of nano bamboo charcoal antibacterial fibers for pets. Background technique: [0002] Nowadays, as people's requirements for clothing are getting higher and higher, clothing made of antibacterial fibers will be welcomed by people. At the same time, due to the continuous reduction of petroleum resources, more and more renewable resources have been developed, especially the requirements for environmental protection. Bamboo charcoal has a wide range of sources, is simple to prepare, and meets the requirements of environmental protection at the same time. Most importantly, bamboo charcoal fiber has good advantages. Bamboo charcoal has a special structure, its molecular structure is hexagonal, the charcoal is dense, the specific gravity is large, and there are many pores. Contains rich natural minerals such as potassium, magnesium, iron, calcium, zirconium, e...
