Flash dyeing production method for textiles

Abstract

Disclosed is a flash dyeing production method for textiles. The method comprises the following steps that (1) a preshaping machine removes an oil agent by means of a high temperature method, the shapeof a fabric is stabilized, and the fabric is subjected to dry heating treatment for 10-120 seconds at the temperature of 150-230 DEG C, so that the oil-water content of the fabric is controlled below0.8%; (2) the fabric is dip-dyed through a pad dyeing unit, and the liquid carrying rate of the dyed fabric is controlled at 20-80%; (3) the dyed fabric is subjected to non-contact pre-drying at 150-220 DEG C; (4) the fabric is sent into a drying and color fixing integrated machine for further drying and color fixing; (5) the fabric after being subjected to drying and color fixing enters a cooling unit to be cooled and spread into a finished product. The invention provides the novel high-efficiency continuous flash dyeing production method and complete equipment. The method is low in cost andenergy consumption, free of water washing and sewage discharge and capable of achieving cleaning integration.

Description

technical field [0001] The invention relates to the technical field of textile dyeing, in particular to a production method for flash dyeing of textiles. Background technique [0002] The textile dyeing process is actually the process of dyeing fibers with dyes, and is a very important part of textile dyeing and finishing. In order to achieve the wearing performance of textiles, after the traditional textile dyeing, the textiles need to be washed, softened, dried and set. The purpose of washing is to remove the floating color and the additives left on the fabric. The color water, sewage, and waste water produced by washing are pollution sources that directly affect the environment. 100% of them must be treated with sewage before they can be reused or discharged. Wastewater treatment costs are currently high. Wastewater treatment is difficult, which not only results in waste of energy, but also secondary re-pollution poses a greater potential hazard to groundwater. Therefo...

AI Technical Summary

Problems solved by technology

Advantages: bright color, good level dyeing; Disadvantages: water consumption, energy consumption, separate softening, dehydration, cloth arrangement, long production process

[0005] Hot-melt dyeing: using open-width padding, which has the advantages of high production efficiency and low energy consumption, but has the disadvantages of poor level dyeing, low color yield, and more floating colors in dark colors

[0006] Supercritical liquid: such as carbon dioxide anhydrous dyeing, this method requires high temperature and high pressure process conditions, complex equipment, high cost of implementation, and there are still potential safety hazards in mass production
