[0015] The preparation method of medical chitosan antibacterial fiber thread comprises the steps:

[0016] (1) Material selection: choose chitosan antibacterial fiber filament, its specification is 105D-210D, diameter is 0.1-0.5mm; the chitosan antibacterial fiber filament treatment process is: chitosan fiber is beaten and chopped Dispersing, using sodium dodecylbenzene sulfonate to wash and pretreat chitosan fibers, adding a dispersant to obtain chitosan antibacterial fiber filaments;

[0017] (2) Doubling: 2-5 treated chitosan antibacterial fiber filaments are used for doubling and 1 strand;

[0018] (3) Twisting: After paralleling, the chitosan antibacterial fiber filaments are twisted through a twisting machine, and the transmission belt of the twisting machine is tight and tight. Each filament must be controlled by a tension regulator, and its speed and twist are measured regularly , the twist is less than 20 twists / m;

[0019] (4) Heat setting: Heat the twisted chitosa...

Abstract

The invention discloses a manufacturing method of medical chitosan antibacterial fibers. The manufacturing method includes selecting chitosan antibacterial fiber filaments subjected to treatment, subjecting the fiber filaments to doubling, twisting and thermal shaping, and twisting a plurality of chitosan antibacterial fiber strands after thermal shaping into medical chitosan antibacterial fibers by a twister. The manufacturing method is simple in process and the medical chitosan antibacterial fibers are good in antibacterial and sterile effect.

Description

technical field [0001] The invention belongs to the technical field of ropes, and in particular relates to a preparation method of medical chitosan antibacterial fiber thread, which is suitable for the field of medical antibacterial and sterilization. Background technique [0002] Antibacterial fibers are fibers mixed with antibacterial agents or treated with antibacterial surfaces. They have antibacterial and sterilizing functions against methicillin-resistant Staphylococcus aureus, and can prevent infection and infection. The antibacterial fiber enables the antibacterial agent to dissolve slowly, forming an antibacterial zone on the surface of the fiber. Even if the surface antibacterial agent is washed off, new antibacterial agent will overflow to form a new antibacterial zone. However, common antibacterial fibers have poor antibacterial and bactericidal effects, and the preparation process of antibacterial fibers is complicated. Contents of the invention [0003] The ...
