摘要
本技术用接枝剂 CS 在纤维素纤维上接枝改性,使直接翠蓝 GL 对纤维的直接性增加,使该染料的上染百分率提高,从而达到降低成本、减少三废、提高产品质量的目的。
The substantivity and exhaustion rate of Direct Turquoise Blue GL(C.I. Direct Blue86,74180)are raised in the graft modification conducted on cell- ulose fiber using graft agent CS.As a result of applying this technique,pro- duction cost is lowered,waste material reduced,and product quality improved.
