Abstract

The invention discloses a preparation method of cationic heat-absorbing and perspiration superfine fibres, which comprises the following steps: firstly, pre-crystallizing a material, drying with drying hot air, wherein the material is a cationic dye dyeable copolymer; secondly, feeding the material into a screw extruder in a screw way: thirdly, filtering the material extruded by the extruder, and ensuring the continuous production spinning and the constant pressure of the screw extruder during filtering; and finally, putting a mixture coming out of a filter into a spinning pack to be sprayed out of a spinneret through the spinning pack, and then forming the cationic heat-absorbing and perspiration superfine fibres by winding. The fibre prepared by the invention has heat-absorbing and perspiration functions, and the fabric has delicate touch, and good drapability, breathability and dyeability.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation, in particular to a method for preparing cationic heat-absorbing and sweat-wicking superfine fibers. Background technique [0002] Polyester has the characteristics of high modulus, high strength, good elasticity and shape retention, and is not easy to wrinkle, so it is an ideal control material. However, due to the lack of functional groups in polyester macromolecules that can combine with direct dyes, acid dyes, basic dyes, etc., although there are ester groups that can form hydrogen bonds with disperse dyes, the theoretical crystallinity is high, the result is compact, and the dye molecules are not easy. Into the fiber, making dyeing difficult and monotonous. The fibers made do not have the function of absorbing heat and wicking sweat. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing cationic heat-absorbing and sweat-wick...
