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.
