Abstract

The present invention is viscose fiber and its preparation process, belongs to the field of texture technology, and solves the problem of enabling fiber possess antiseptic and virucidal function. The technological scheme includes that the bactericidal fiber consists of fiber forming polymer in 99.0-99.9 wt% and nanometer silver grains as bactericide in 0.1-1.0 wt%, and that during the preparation of the bactericidal fiber, nanometer silver grains in nanometer silver aqua colloid form is added into the spinning solution before conventional wet spinning to obtain bactericidal viscose fiber. The obtained viscose fiber has lasting bactericidal effect and no toxic side effect.

Description

technical field [0001] The invention relates to a viscose fiber and belongs to the technical field of textiles. Background technique [0002] With the development of society and the continuous improvement of living standards, people's awareness of self-care is increasing, and more and more fiber products are required to be colorful, beautiful and practical, and also have antibacterial and anti-mildew functions. The use of antibacterial fiber products can cut off the transmission of infectious diseases on the one hand, and prevent the product itself from being moldy and damaged. [0003] The antibacterial effect of antibacterial fiber products is inseparable from the type of antibacterial agent used. Antibacterial agents are basically divided into three categories, namely natural antibacterial agents, organic antibacterial agents and inorganic antibacterial agents. Organic antibacterial agents are fast and effective in inhibiting bacteria and killing bacteria, but they have...
