Abstract: The cashmere knitting was finished with sericin solutions in order to improve its pilling resistance. The relationship between the finishing processing parameters and the propensity to pilling was analyzed and the laundry-proof property of the finished cashmere knitting and the unfinished one was compared too. The results show that, under the condition of the concentration of the sericin solution 8%(on the weight of fabric), the pH value 6, the temperature 50℃, and the impregnating time 30 minutes, the pilling property of the cashmere knitting can be improved in great degree. The pilling grade of the finished cashmere knitting can also be enhanced by more than one grade. The perfect laundry-proof property can keep the pilling grade of the finished cashmere knitting after washing 20 times the same as the unwashed. The properties such as moisture regain, shrinkage and fabric bursting strength were tested and compared. It shows that these properties of cashmere knitting were improved after finished, and the feeling of the finished one that decreased slightly is pretty soft.
