Abstract

The present invention utilizes the combination of characteristics of diacetate filament and air-texturing technique, and fully utilizes the short fibrillation effect of diacetate filament in air-texturing production process, and has no need of adding loop-abrading device, and can produce the air-textured yarn with more rich natural spun yarn style.

Description

technical field [0001] The invention belongs to the field of textiles, and relates to a method for preparing air-varying yarns composited with diacetate and polyester / brocade filaments with a short fiber effect. Background technique [0002] The air deformation technology was first successfully researched by the DuPont Company of the United States in the early 1950s, and its key component is the nozzle. The process is that compressed air is introduced into the nozzle, and the deformed multifilament is subjected to high-speed turbulence in the nozzle, and each single filament is separated from each other and moves violently in the turbulent flow. When the filament is tension-free (that is, overfeed) from At the moment when the nozzle is output, many loops, arcs and tangles are produced on the loose filament bundle. This irregularly entangled form makes the smooth filament soft, bulky and low-elasticity. Empty variable yarn. The purpose of the air deformation technology is t...
