Spinning system of ultra-low boiling water shrinkage polyester DTY fiber and spinning method thereof

Abstract

The invention discloses a spinning system of ultra-low boiling water shrinkage polyester DTY fiber and a spinning method thereof, and relates to the technical field of spinning. The system sequentially comprises an extruder, a metering pump, a spinning box, a winding device, a net forming device, a reinforcing device and a winding device according to the production sequence of a spinning production line, wherein a fixed bottom plate is fixedly installed at the bottom of the extruder, a working motor and an extrusion bin are fixedly installed at two sides of the upper end face of the fixed bottom plate respectively, a feed hopper is fixedly arranged on the upper end face of the extrusion bin, a plurality of communicating pipes are fixedly arranged at the periphery of the spinning box, and conveying pipes are fixedly connected among the communicating pipes. According to the spinning system and the spinning method thereof, not only can the tension of the yarn be effectively controlled, but also the yarn can be uniformly wound on the annular outer surface of a winding roller, and meanwhile residual extruded plastic adhering to the inner wall of the extrusion bin can be scraped off, sothat the stirring and transmission efficiency is improved, and the accumulation of materials is avoided.

Description

technical field [0001] The invention relates to the technical field of spinning, in particular to a spinning system and spinning method of polyester DTY fibers with ultra-low boiling water shrinkage. Background technique [0002] Polyester low elastic yarn, referred to as DTY, is a type of textured yarn of polyester chemical fiber. It is made of polyester chips, high-speed spinning polyester pre-oriented yarn, and then processed by drafting and false twisting. It has a short process, With high efficiency and good quality, it is an ideal raw material for knitting or weaving. It is suitable for making clothing fabrics, bedding and decorative products. Among them, fine denier silk is more suitable for imitation silk fabrics, and medium and thick denier silk can be used for wool-like fabrics. For fabrics, when polyester DTY fibers are produced, a designated spinning system is required to process them. [0003] However, in the existing spinning system and its spinning method, in...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a spinning system and spinning method of ultra-low boiling water shrinkage polyester DTY fiber, which solves the problem that there is no better yarn guiding mechanism inside, causing the external yarn to be wound on the winding roller At one position, the yarn cannot be evenly wound on the annular outer surface of the winding roller, so as to effectively complete the winding work of the yarn
