Problems solved by technology

However, due to the difference in polarity, the force between nano-silver and the fabric is very weak, and the preparation process is also a process of physical compounding. Therefore, after the product is washed many times, the bactericidal effect of nano-silver will gradually weaken.

Abstract

The invention provides a nano silver bamboo charcoal fiber which is a bamboo charcoal fiber containing nano vesicles. Raw materials for preparing the nano silver bamboo charcoal fiber at least includethe nano vesicles, bamboo charcoal powder, water-based polymer materials, modified chitosan and additives. The nano silver bamboo charcoal fiber is prepared by adopting a dry-wet-wet three-coagulation bath method.

Description

technical field [0001] The invention relates to the technical field of clothing, in particular to a nano-silver bamboo charcoal fiber sterilizing underwear and a preparation method thereof. Background technique [0002] Sweat, dander, etc. in underwear are multiplied for nutrition, which poses a threat to human health and even induces various diseases. Microorganisms such as bacteria, bacteria, and yeast are found almost everywhere, and materials such as textiles can easily reproduce large numbers of microorganisms and can even be broken down by various microorganisms. There is a warm and humid microclimate close to the human body, and there are many bacterial foods, such as sweat and other secretions, dander, fat and worn threads, so the microenvironment composed of textiles and the human body provides an ideal environment for the reproduction and growth of microorganisms. Conditions, and microorganisms can withstand high temperatures, even under very severe washing condit...
