Abstract

The invention discloses a method for manufacturing breathable moisture absorption modified polyester fibers. The method comprises the following steps of: A) adding sepiolite into a 2 mass percent hydrochloric acid solution in a mass ratio of 1: (6-10), stirring for 0.5 to 1.5 hours, dehydrating and drying, and thus obtaining activated sepiolite; B) adding the activated sepiolite into a 4 mass percent cetyl trimethyl ammonium bromide solution in a mass ratio of 1: (4-6), stirring for 2 to 3 hours, drying, and thus obtaining organic sepiolite; C) taking 0.1 to 0.5 mass parts of glycol diglycidyl diethyl ether, 0.5 to 1.5 mass parts of sodium carboxymethylcellulose, 4 to 6 mass parts of sodium polyacrylate, 0.05 to 0.15 mass part of potassium persulfate, 1 to 3 mass parts of organic sepiolite and 6 to 10 mass parts of water, performing stirring reaction for 1 to 3 hours at the temperature of between 70 and 90 DEG C, drying, grinding, and thus obtaining a modified functional material, thegrain diameter of which is not more than 15 microns; and D) adding 5 to 15 parts of functional material into 85 to 95 parts of polyester melt, uniformly mixing the functional material into the polyester melt with high-speed stirring, and spinning by using a spinneret plate with 'cross' special-shaped holes.

Description

technical field [0001] The invention relates to a method for manufacturing a highly hygroscopic modified polyester fiber, which belongs to the technical field of textiles. 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, more and more attention has been paid to the development of hygroscopic polyester fibers, and 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 overa...
