Aiming at the problem that cashmere fabric has pilling with adverse effect on its wearability,the experiment adopts the oxidation+keratin synergistic post-treatment method to change the technical parameters of the process.The experimental results show that the amount of sodium percarbonate in the oxidation solution reaches 8.0 g/L,the amount of TAED is 1.5 g/L,the amount of oxygen bleaching stabilizer is 4.0 g/L,the oxidation treatment time is 25 min,the amount of catalase is 0.6 g/L,the oxidation treatment time is 30 min,and oxidation treatment temperature is 50 ℃.The amount of keratin in the keratin solution is 2.5 g/L,the keratin treatment time is 20 min,and the keratin treatment temperature is 40 ℃.Compared with the untreated cashmere fabric,the anti-pilling ability reaches level 3.0,the color difference and hand feel have no obvious changes,and the breaking strength is slightly reduced,which meets the production requirements of cashmere fabric.
