Study on one-bath dyeing of chitin-cotton blended fabrics

ZHU Ping,ZHOU Xiao-dong,WANG Bing,DONG Chao-hong,ZHANG Jian-bo(State Key Lab.New Fiber Mater.Modern Text.,Qingdao Univ.,Qingdao 266071,China)  
Shortcomings such as low dye uptake on cotton,light color on cotton and bad homochromicity of blended fabrics occur in reactive dye dyeing of chitin-cotton blended fabrics.An optimal pretreatment process was obtained by the use of cationic etherifying agent for the pretreatment and the comparisons of the dyed fabrics for their apparent color deepness(K/S value),color intensity indices L*,a* and b*,as well as water-wash fastness.The chitin-cotton blended textile was pretreated for 40 min at 60 ℃ with cationic agent at 50 g/L and NaOH at 15 g/L,and dyed with reactive dyes to give good color deepness and leveling,as well as improved antibacterial property.
