Dust-removing blowing device

Abstract

The invention relates to a novel dust removal and blowing device for spinning during the fiber production process. The device comprises a microfog water film dust removal device (1), a temperature andhumidity air conditioning unit (2), a blower (3), a blast pipe (4) and a three-stage rectification blowing device (5), wherein, an air outlet of the microfog water film dust removal device (1) is connected with an air inlet of the temperature and humidity air conditioning unit (2), an air outlet of the temperature and humidity air conditioning unit (2) is connected with an air inlet of the blower(3), and an air outlet of the blower (3) is connected with an air inlet of the three-stage rectification blowing device through the blast pipe (4). The device can remove dust in the air, improve theoutlet uniformity, and avoid rewinding to cause the defects of products and so on.

Description

technical field [0001] The invention relates to a novel dust removal blowing device for spinning in the fiber production process. It belongs to the technical field of fiber production equipment. Background technique [0002] As the sewing speed of garments continues to increase, the strength requirements for sewing threads are getting higher and higher. High-grade sewing threads use bright fibers as the best raw materials. [0003] Bright polyester staple fibers currently on the market generally contain 800-1200ppm of barium sulfate or titanium dioxide additives to improve processing performance. Although the product has high strength, the luster effect of the fiber is greatly weakened after adding barium sulfate or titanium dioxide, so it cannot be used to produce high-grade sewing threads; without adding barium sulfate or titanium dioxide, the drafting performance of the primary fiber during fiber production is greatly affected , the product is difficult to meet the stre...

AI Technical Summary

Problems solved by technology

Although the product has high strength, the luster effect of the fiber is greatly weakened after adding barium sulfate or titanium dioxide, so it cannot be used to produce high-grade sewing threads; without adding barium sulfate or titanium dioxide, the drafting performance of the primary fiber during fiber production is greatly affected , the product is difficult to meet the strength requirements for the production of high-speed sewing thread

If the required strength is to be achieved, a high temperature and slow cooling process is required in the spinning process, and a blowing device is required in the slow cooling process. The traditional blowing device uses air to cool directly through the mesh cylinder, and the air contains dust. , The uniformity of the air outlet does not meet the requirements, and there are defects such as prone to parallel wires and product defects
