Application of compound deepening agent on knitted fabric
Dyeing ultra dark fabrics has problems such as dye saturation but insufficient color depth.By combining different glass transition temperatures of darkening agents,a double-layer reflective surface was formed on the fabric to explore its application effect on knitted fabrics.The results showed that the composite ratio of deepening agent m(polysiloxane TF-413)∶m(polyacrylate M-431SX)=2∶1,the mass concentration of deepening agent was 40 g/L,and the setting machine was set in a 6-section oven at 170℃ at a speed of 26 m/min.The deepening rate of the finished fabric was as high as 45.89%.Compared with the untreated fabric,the color fastness to soap washing was basically the same,and the color fastness to wet friction could be im-proved by 0.5 level.
