Spinning system and spinning method of polyester dty fiber with ultra-low boiling water shrinkage

Abstract

The invention discloses a spinning system and a spinning method for polyester DTY fibers with ultra-low boiling water shrinkage rate. The invention relates to the technical field of spinning, which comprises an extruder, a metering pump, a spinning box, Winding device, web forming device, reinforcing device and coiling device, the bottom of the extruder is fixedly installed with a fixed base plate, and the two sides of the upper surface of the fixed base plate are respectively fixedly installed with a working motor and an extrusion chamber. A feeding hopper is fixedly installed on the upper end of the bin, and several connecting pipes are fixedly installed around the spinning box, and a delivery pipe is fixedly connected between the several connecting pipes. The spinning system and its spinning method can not only effectively control the tension of the yarn, but also make the yarn evenly wound on the outer surface of the winding roller ring, and at the same time, it can also prevent the residues adhered to the inner wall of the extrusion chamber. The extruded material is scraped off, which improves the mixing and transmission efficiency and avoids the accumulation of materials.

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
