The invention discloses a method for improving fabric tearing resistance and pilling resistance after multiple times of washing, and belongs to the technical field of fabric printing and
dyeing. Comprising the following steps: (1) pretreatment: turning a gray fabric, sewing, padding in a cold pad batch working solution for piling, padding in a scouring and bleaching working solution, singeing, feeding the fabric through a mercerizing
machine, padding in an alkali solution, washing and the like to obtain a semi-finished product; (2)
dyeing: feeding the semi-finished product into cloth, padding in a
dyeing solution at
room temperature, then sequentially carrying out
infrared drying, hot
air drying,
drying, baking, cold water roller treatment,
cropping frame treatment and cloth feeding padding in a reducing solution, and finally sequentially carrying out cold
water washing and other treatment to obtain dyed cloth; and (3) after-finishing: feeding the dyed cloth, padding in an after-finishing working solution, and then sequentially carrying out photoelectric weft straightening, tentering baking, cold water rolling and the like. The method effectively solves the problems that in the prior art, improvement of the tearing performance of the fabric is incompatible with the repeated washing resistance and the pilling resistance, the tearing
loss rate of the fabric is high, and the pilling resistance has adverse effects on the tearing of the fabric.
