涤/棉混纺织物一浴染色及低温皂洗工艺OA

To improve the color depth value and color fastness of the fabric,the one bath dyeing and low temperature soaping process of polyester/cotton blended fabric were explored.The color parameters,color fastness and burnt out cotton effect of fabric under different concentrations of disperse dyes were studied,and the ratio and dosage of disperse/reactive dyes were optimized.The parameters such as soaping tempera-ture,soaping concentration and soaping time were optimized based on orthogonal experimental design.The re-sults showed the fabric had good color depth value,color fastness to washing and rubbing when dyed with disperse black WECT.When the concentration was 38 g/L,and the dispersion/activity ratio was about 1∶1,the rear vehicle speed could be increased to 70-80 m/min.Under the optimal soaping process conditions of soap-ing temperature 60℃,soaping concentration 8 g/L and soaping time 2 min,the color fastness to wet rubbing of the fabric could be reached to level 3-4.
