A short-process washing-free dyeing method for polyester plush fabric

Abstract

The invention discloses a short-process washing-free dyeing method for polyester plush cloth, which belongs to the field of textile printing and dyeing. The specific dyeing working liquid of the method of the present invention is dyed by dipping and padding. In the baking stage, the process of first heating up, then cooling down, and then heating up is adopted, so that the disperse dye can fully diffuse into the fiber, and the fiber is dyed to complete the curing process. color. The light fastness of the dyed polyester plush cloth prepared by the method of the invention can reach 6 to 7 grades, and the washing fastness can reach 4 to 5 grades, realizing the washing-free dyeing of the polyester plush cloth.

Description

technical field

[0001] The invention relates to a short-process washing-free dyeing method for polyester plush cloth, which belongs to the field of textile printing and dyeing. Background technique

[0002] Polyester fiber has excellent new performance, high strength, good elasticity, good heat resistance, thermoplasticity and abrasion resistance, so it is widely used in the textile field. Polyester is a hydrophobic fiber, its macromolecules are densely arranged, its glass transition temperature is high, and its molecular structure lacks active groups that can combine with dyes like cellulose or protein fibers, so its dyeing process is relatively difficult, and generally requires Disperse dyes are dyed by high temperature and high pressure method (120°C~130°C) or hot melt (180°C~220°C). into the interior of the fiber.

[0003] The existing polyester cloth dyeing process requires a large amount of water in the steps of neutralization treatment, dyeing, and post-reduction cl...
