Dyeing method and device with anti-splashing structure for polyester chemical fiber cloth spinning

Abstract

The invention discloses a dyeing method and device with an anti-splashing structure for polyester chemical fiber cloth spinning, and belongs to the technical field of spinning dyeing. The method comprises the following steps that pretreatment before dyeing is conducted, wherein polyester fabric needing to be dyed is put into a cleaning machine; when the water level reaches 13-17%, a laundry detergent and color bleaching powder are added; when the water level reaches 15-20%, heating is conducted to make the water temperature rise to 30-45 DEG C, the washing rotating speed of the cleaning machine is 30-40 r / min at the moment; and after cleaning is completed, the polyester fabric is dehydrated, the operation is repeated, and cleaning is conducted three times. According to the dyeing method with the anti-splashing structure for polyester chemical fiber cloth spinning, by arranging the pretreatment process before dyeing, oil dirt, dust and pigment generated on the surface of the polyester fabric in the production process can be treated thoroughly, therefore, the problem that when the polyester fabric is dyed, due to the fact that the polyester fabric is not cleaned thoroughly, dyeing defects such as various dyeing defects and color spots are generated in the dyeing process is avoided, and the normal dyeing quality of the polyester fabric is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and specifically relates to a dyeing method and device with a splash-proof structure for polyester chemical fiber cloth weaving. Background technique [0002] Polyester is an important variety of synthetic fibers and is the trade name of polyester fibers in my country. It is produced by esterification or transesterification and polycondensation reactions using purified terephthalic acid or dimethyl terephthalate and ethylene glycol as raw materials. The obtained fiber-forming high polymer-polyethylene terephthalate, the fiber made by spinning and post-processing, often needs to be dyed after the polyester fabric is produced, but the existing polyester Before the fabric is dyed, the cleaning of the polyester fabric is not in place, which will easily lead to various color spots and stains on the outer surface of the polyester fabric after printing and dyeing, which will affect the appearance o...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a dyeing method and device with a splash-proof structure for polyester chemical fiber fabrics, which solves the problem that the cleaning of ordinary polyester fabrics before dyeing is not thorough enough, which easily leads to stains after printing and dyeing. The outer surface of the polyester fabric has dyeing defects such as various color patterns and stains, which affect the appearance of the polyester fabric, and the ordinary dyeing device is not convenient for the staff to wind the polyester fabric on the surface of the roller
