Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide an ultrafine composite stretched yarn and its processing technology, which solves the problem that the conventional spinning preparation method of pre-prepared polyester and modified nylon is mainly used at present. It has ultra-fine composite stretched yarn, but in the process of making stretched yarn, the material is not treated with breathability, moisture absorption, extension and stability, so that the finished spinning only has elastic characteristics, and then the spinning There is a big lack of problem in the application effect

Abstract

The invention discloses an ultra-fine composite elasticized wire and a processing technique thereof, and belongs to the technical field of processing of elasticized wires. The technique adopts nylon and a modifier to form modified nylon as a raw material by methods of high-temperature dissolution and doping, adds a surfactant, an antistatic agent and a stabilizer, and forms the 'barrier type' ultra-fine composite elasticized wire through a series of processing techniques, the 'barrier type' structure in the elasticized wire makes the elasticized wire have good stability and gas permeability, thereby manufacturing the novel ultra-fine composite elasticized wire with high gas permeability, high moisture absorption, high ductility and high stability, and the wire is simple in production modesand wide in use rate.

Description

technical field [0001] The invention relates to an ultrafine composite textured yarn and a processing technology thereof, belonging to the technical field of textured yarn preparation. Background technique [0002] The methods for preparing ultrafine fibers by composite spinning mainly include island-in-the-sea composite spinning and split-type composite spinning. Among them, split-type composite spinning is mainly based on polyester-nylon composite spinning, and the incompatibility of polyester and nylon is utilized. The fiber is opened under the action of the subsequent alkali reduction or a certain mechanical force to obtain ultra-fine denier fibers. Compared with ordinary fibers, microfibers have extremely small linear density and high specific surface area. The fabrics woven have the characteristics of high coverage, soft touch, comfortable wearing, and soft colors. They are widely used in suede and imitation peach skin. The production of velvet, microfiber leather bas...
