Problems solved by technology

Although this kind of fiber has antibacterial properties, it also has the irreparable defects of synthetic fibers, namely: when used in clothing, sanitary materials, and bedding, it has poor hygroscopicity and antistatic properties, and it is antibacterial after being subjected to high temperatures, chemicals, and repeated washing. The antibacterial properties are reduced, and the real antibacterial purpose cannot be achieved. At the same time, the drug will also cause certain allergic reactions and affect the performance of taking; even if inorganic antibacterial agents are used, most of them contain heavy metal ions, which are harmful to the human body. Silver-based antibacterial agents are less harmful to the human body among antibacterial agents, and are beneficial to the human body when used in small amounts, and have a strong ability to kill Staphylococcus aureus and Escherichia coli

Abstract

The invention relates to a manufacture method for antibiotic mucilage glue fiber that uses nanometer silver as additive. The method includes the following steps: mixing grains, making glue, spinning, beaming, cutting, refining, drying, packing nanometer silver antibiotic agent; mixing grains, making glue, spinning, beaming, cutting, refining, drying and packing antibiotic mucilage glue fiber. It has the advantages of asepsis, strong antibiotic effect, long effecting time and strong dry-wet rigidity.

Description

technical field [0001] The invention relates to the production of antibacterial fibers from cellulose pulp and nano-silver colloid solution, more precisely, the preparation method of silver-based antibacterial viscose fibers. technical background [0002] At present, most of the antibacterial fibers are synthetic fibers, and the antibacterial agents are mainly organic antibacterial agents, which are added through melt spinning or post-finishing. Although this kind of fiber has antibacterial properties, it also has the irreparable defects of synthetic fibers, namely: when used in clothing, sanitary materials, and bedding, it has poor hygroscopicity and antistatic properties, and it is antibacterial after being subjected to high temperatures, chemicals, and repeated washing. The antibacterial properties are reduced, and the real antibacterial purpose cannot be achieved. At the same time, the drug will also cause certain allergic reactions and affect the performance of taking; ...
