Problems solved by technology

[0005] Studies have shown that the color fastness to wet rubbing of fabrics dyed with reactive dyes is closely related to the depth of dyeing, that is, during wet rubbing, the amount of color transfer and the depth of dyeing are almost in a good linear relationship. Among them, the supersaturation of dyes during dyeing It is the most ...

Embodiment 1

[0079] Embodiment 1: a kind of processing method of promoting the wet rubbing fastness of woven dark-colored cloth, carry out according to the following steps: (1), distributing cloth

[0080] According to the "production notice" to get the gray cloth, check whether the cloth is consistent with the production process card before distributing the cloth. According to the number of meters of each order, select an appropriate number of gray cloth bags for distribution, so that the number of meters for distribution is consistent with the number of meters required by the production process card. When distributing, implement one truck and one truck, and do not place more indiscriminately. Make a detailed record of the order quantity on the production process card. Production order number: 713149, gray fabric: 70"20*16+70D Zhigong cloth, finished product width: 57-58", composition: cotton, color: dark blue, order quantity: 18847M.

Abstract

The invention discloses a process method, and particularly relates to a process method for improving woven dark cloth wet rubbing fastness. The process method includes the steps: (1) cloth distribution; singeing, cooling reaction and desizing; scouring and bleaching; mercerizing; pad dyeing or jig dyeing; wet rubbing fastness improver and auxiliary selection and preparation; wet rubbing fastness improver finishing; over-soft sizing; pre-shrinking; finished product inspection. According to the process method for improving the woven dark cloth wet rubbing fastness, production processes of all procedures are controlled, the capillary effect of a fabric is effectively improved, the surface finish degree of the fabric is improved, friction resistance is reduced, surface dyeing is decreased by strengthening soaping and washing after dyeing, wet rubbing fastness improvers of waterborne polyurethane complexes (Jiangxi Luxi County Xianghua Fine Chemical Co., Ltd., similarly hereinafter) are added after dyeing, under the assistant effects of assistant stabilizers 203 and cracking agents 109, the process method effectively solves the problem that oil floating points are generated in continuous production for 2000 meters or more when single wet rubbing fastness improvers are added in the past, the wet rubbing fastness of dark dyed cloth is improved by one level or more, corresponding washing fastness is improved, pH (potential of hydrogen) values meet requirements, continuous production and product quality are ensured, and a cloth surface has a certain color-deepening effect and softening effect, so that customer satisfaction is achieved.

Description

technical field [0001] The invention relates to a process method, in particular to a process method for improving the wet rubbing fastness of woven dark-colored cloth. Background technique [0002] Cotton fabrics are loved by people because of their moisture absorption and breathability. Reactive dyes are bright in color and complete in color spectrum, and are the main dyes for dyeing cotton fabrics. However, when cotton fabrics are dyed with reactive dyes in dark colors, the wet fastness is often unsatisfactory, especially the wet rubbing fastness, which is generally only about level 2, resulting in poor wearing performance. With the improvement of living standards, consumers' requirements for the quality of textiles are also constantly improving. More and more foreign merchants' textile orders and domestic brand clothing fabric orders require "color fastness to wet rubbing" among the technical requirements. Reach level 3 or higher. [0003] Therefore, how to improve the ...
