A production process of super-imitation silk-type brocade ammonia air-covered silk

Abstract

The embodiment of the invention discloses a production technology of a super simulation silk kam ammonia air-coated wire. The production technology comprises the following steps: a) melt spinning; b) laterally blowing cooling; c) oiling and bundling; d) winding, namely finishing the production processes of chinlon drafting, chinlon false twisting and elasticizing, spandex drafting, spandex wire air-coating, winding and molding one time on an 'elasticizing and blanking all-in-one machine' by improving a blank wire processing technology, and critical components such as a network nozzle and the like, concretely including the steps e) to g), e), heating a guide wire; f) cooling and false twisting; and g) drafting and networking. The production technology is formed by spinning and blanking in a two-stage manner by adopting an improved section shape of a spinneret orifice, the blanking all-in-one machine, and improvement of technological parameters in the steps; bad phenomena that a POY (polyester pre-oriented yarn) easily generates uneven fibre number, low breaking strength and the like in the spinning process are solved; and meanwhile, the problems of broken filaments, broken ends and the like easily generated in false twist deformation of elasticizing and blanking are also solved.

Description

Technical field [0001] The invention relates to the production field of spandex covered silk products, in particular to a production process of super-simulated silk-type nylon air covered silk products. Background technique [0002] Natural fiber has the advantages of health, comfort, and environmental protection, but lacks functionality and has limited developability. The traditional chemical fiber's poor moisture absorption, poor comfort, and poor hand feel also limit the development of chemical fiber. Therefore, starting from the comfort of natural fibers, the simulation transformation of chemical fibers can achieve natural fibers in terms of appearance, health and comfort, and also achieve functionality, safety and environmental protection, and can look natural, better than natural . The cross-sections of different types of natural fibers have their own different shapes. For example, the cross-section of cotton fiber is irregularly round with a cavity; the cross-section of ...
