低分子量、含氮量适中的聚环氧氯丙烷胺化物对纤维素纤维改性工艺的研究

A Study on the Modification of Cellulosic Fibers with Low Molecular Weight and Moderate Nitrogen Content of PECH-amine

研究了低分子量、含氮适中的聚环氧氯丙烷胺化物对纤维素纤维改性的工艺条件,讨论了NaOH、PECH1- a3和染色时盐用量等影响因素。改性后的纤维素纤维具有优良的染色性能,对增深染色、降低环境污染、降低染色成本有很好的作用。

The modification process of cellulosic fibers with low molecular weight and moderate nitrogen content of PECH-amine was studied. The doses of sodium hydroxide and PECH-amine for modifying cotton and the salt for dyeing modified cotton were discussed; It was found that the modified cellulosic fiber exhibited better dyeability than the one unmodified. The PECH-amine modified cellulosic fibers could be dyed to deeper shades, with less environment pollution, and the dyeing cost was lower.
