Problems solved by technology

For velvet fabrics such as corduroy, plain velvet, and twill velvet, even under the same process conditions, the wet rubbing fastness is worse than that of ordinary fabrics, because these fabrics will have fiber fragments remaining on the surface of the fabric. On the fluff, the fibers are mechanically damaged by fluff, which causes the micro fluff to be easily scratched and dropped. Therefore, the wet rubbing fastness is worse and it is not easy to improve

Abstract

The invention discloses a production process for improving wet rubbing fastness of reactive dye. The process comprises the following steps: pretreating and dyeing a fabric; washing the fabric by soap; drying the fabric; padding a fixing agent; drying the fabric; padding a wet rubbing fastness improver; drying the fabric; napping the fabric; baking and stentering the fabric at 130 DEG C; carding the fabric; shearing and sewing the fabric into a finished product, wherein, the step of pretreating and dyeing the fabric comprises cold pad-batch by a refined enzyme-peroxide one bath process, open washing, dyeing and baking; the step of washing by soap adopts a LIPOTOL RK-5Z soaping agent; in the step of padding the fixing agent, the fixing agent adopts JD-427 formaldehyde-free fixing agent; and the improver in the step of padding the wet rubbing fastness improver adopts 1504 wet rubbing fastness improver. The method can save water, energy consumption and time, can thoroughly remove impurities, has small dye dosage, and can improve the wet rubbing fastness of the reactive dye.

Description

technical field [0001] The invention relates to a production process for improving the wet rubbing fastness of reactive dyes. Background technique [0002] Reactive dyes are widely used in the dyeing and printing of cellulose fibers due to their bright color, complete chromatogram, convenient use, low price, and wide applicability, but they have low fixation rate and poor rubbing fastness, especially in dark colors. Wet rubbing fastness has been low. It is mainly used for medium and light colors, and its rubbing fastness can generally reach the standard: soaping fastness 4 grades, staining fastness 4 grades, dry rubbing fastness 3-4 grades, wet rubbing fastness 3 grades. At present, reactive dyes are also widely used in many dark-colored varieties, but the wet rubbing fastness of reactive dyes in dark-colored colors generally only reaches grades 1.5 to 2. At present, many customers have high requirements for wet rubbing fastness. Even dark and thick color varieties require...
