Abstract

The invention provides a finishing method capable of effectively reducing the nylon dyeing difference. According to the finishing method, oil is removed by an oil remover DM-1119N, an oil-removed fabric is dyed with a mixed working solution of a dye, a diluent and an acid dye leveling agent, and in the fabric dying process, reworking is carried out in the case of vat difference, cloth difference and color difference between left and right parts of the same piece of cloth. Through the combined process of oil removal and dyeing, dyeing difference of the nylon fabric in the dyeing process is prevented, and color tones, color dots and color spots occurring in the dyeing process of the nylon fabric are prevented.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing and finishing, and more specifically relates to a finishing method for effectively reducing nylon dyeing differences. Background technique [0002] Nylon is the main variety of synthetic fibers, and my country's nylon production accounts for about 70% of the world's total. Nylon fiber has the advantages of abrasion resistance, good elasticity, high strength and elongation, low relative density, and mildew resistance. Nylon fibers are used in high-end women's underwear, swimwear, and sportswear. The dyeing uniformity of nylon fabrics directly affects the appearance, grade and quality of finished products, and affects the economic benefits of manufacturers. [0003] After inquiry, there is currently no public solution to solve a series of problems such as nylon fabric gap, cylinder difference, color flower, color point, etc., and once the above problems occur, there is no corresponding repair ...
