Abstract

The present invention discloses preparation process of antiseptic viscose fiber. The antiseptic viscose fiber is prepared through adding nanometer silver particle of size smaller than 100 nm as antiseptic in the form of nanometer colloid aqua into spinning liquid and subsequent conventional wet spinning process. It has lasting antiseptic effect and no side toxic effect on human body, as well as excellent mechanical performance. It may be used widely in industry, agriculture, medicine and other fields.

Description

technical field [0001] The invention relates to a preparation method of viscose fiber, in particular to a preparation method of antibacterial viscose fiber. Background technique [0002] With the development of society and the continuous improvement of people's living standards, people's awareness of self-health 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...
