Abstract

The invention discloses a preparation method of a hydrophilic antibacterial modified polyester fiber, which adopts the following steps: (A), taking and uniformly mixing 1-3 parts of aluminum oxide, 1-3 parts of diatomite, 1-3 parts of activated sepiolite and 0.01-0.5 part of silver sulfide in part by mass to obtain a mixture; (B), taking 0.1-0.5 part of ethylene glycol diglycidyl ether, 0.5-1.5 parts of sodium carboxymethylcellulose, 4-6 parts of sodium polyacrylate, 0.05-0.15 part of potassium peroxydisulfate, 1-3 parts of the mixture obtained in the step (A) and 6-10 parts of water in the part by mass in the step (A), agitating and reacting the obtained mixture for 1-3 hours at a temperature of 70-90 DEG C, drying a product, and grinding the product to obtain a hydrophilic antibacterial modified material with particle sizes being not more than 15 [mu]m; and (C), adding the hydrophilic antibacterial modified material obtained in the step (B) to a polyester fused mass, agitating the obtained mixture uniformly, and spinning the mixed mixture to obtain a modified polyester fiber, wherein the addition amount of the hydrophilic antibacterial modified material obtained in the step (B) is 5-15% of that of the polyester fused mass in percentage by weight.

Description

technical field [0001] The invention relates to a textile technology method, in particular to a preparation method of water-absorbing antibacterial modified polyester fiber. Background technique [0002] Polyester fiber has a large output and a wide range of uses. However, polyester fiber has a moisture absorption rate of only 0.4%, and poor wearing comfort, especially when the human body sweats, it has difficulty perspiring, giving people a feeling of stuffiness and discomfort. And it brings a series of problems such as easy to accumulate static electricity, easy to absorb dust, and difficult to remove oil stains. [0003] At present, in the research on the modification of polyester fibers at home and abroad, the development of water-absorbent polyester fibers has received more and more attention. There are many ways to make polyester fibers hydrophilic. It is mainly modified in the two processes of spinning and finishing. Most of the spinning modification is the overall...
