High-elasticity and high-strength polyester hot-melt yarn spinning device and preparation process thereof

Abstract

The invention relates to the technical field of polyester silk making, and discloses a high-elasticity and high-strength polyester hot-melt yarn spinning device and a preparation process thereof. The high-elasticity and high-strength polyester hot-melt yarn spinning device comprises a hot-melt stirring disc, wherein a hot-melt cavity is formed in the hot-melt stirring disc; a vertically-through polyester chip feeding port is formed in the upper right end of the hot-melt stirring disc; stirring rods are rotationally arranged in the middle of the hot-melt cavity; the stirring rods are symmetrically arranged up and down; an alternating current motor is fixedly arranged at the upper end of the hot-melt stirring disc; the lower end of an output shaft of the alternating current motor is sleeved with a hot oil sleeve; the hot oil sleeve extends downwards to be communicated with hollow main shafts of the stirring rods; hot oil is injected into the hot oil sleeve; and hot-melt stirring exhaust rods are arranged on the lower side of the hot-melt stirring disc. According to the high-elasticity and high-strength polyester hot-melt yarn spinning device and the preparation process thereof provided by the invention,two stirring devices with the same configuration are arranged on the lower side of one same hot melting stirrer, and the elasticity and the strength of hot-melt raw materials on the two sides are made to be different by adjusting the stirring time of the left hot-melt stirring exhaust rod and the right hot-melt stirring exhaust rod.

Description

technical field [0001] The invention relates to the technical field of polyester filament production, in particular to a high-elasticity and high-strength polyester hot-melt spinning device and a preparation process thereof. Background technique [0002] Polyester is an important variety of synthetic fibers. It is a fiber-forming polymer made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG)—— Polyethylene terephthalate (PET), made by spinning and post-processing, polyester has a wide range of uses, and is widely used in the manufacture of clothing and industrial products. With the improvement of people's demand, the existing polyester yarn The material has higher requirements, for example, it needs to have better elasticity with higher strength, but the strength and elasticity of the existing polyester yarn depend on its chemical characteristics, and it is difficult to reproduce it without changing other chemical characteristics...

AI Technical Summary

Problems solved by technology

[0002] Polyester is an important variety of synthetic fibers, which is based on purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene diphthalate Alcohol (MEG) is used as a raw material to prepare fiber-forming high polymer - polyethylene terephthalate (PET), which is made by spinning and post-processing. Polyester has a wide range of uses and is widely used in the manufacture of clothing and industrial For medium-sized products, with the improvement of people's demand, there are higher requirements for the existing polyester filament materials, such as the need to have good elasticity under high strength, but the strength and elasticity of the existing polyester filaments depend on Its chemical characteristics make it difficult to improve its related properties without changing other chemical characteristics. Therefore, a device and a preparation method that can improve the strength and toughness of polyester filaments without affecting other properties are needed to improve polyester filaments. strength and elasticity
