摘　　要：纤维的湿法后处理(如织物的染色、整理和功能化)产生大量的含染料等化学物质的废液,对环境和人类健康产生不利影响。在合成纤维和再生纤维素纤维行业中,在纤维制备过程中实现着色和功能化是一种有效的解决方案,可减少如原液着色、添加阳离子染色等不利影响。在再生纤维素(如黏胶)中进行纤维级改性的挑战与合成纤维工艺中遇到的挑战不同。尽管可使用基于纤维改性的商业产品,但客户与商家对添加剂与介质相互作用的理解存在差距。研究旨在弥合差距,使纤维改性产品具有更好的可加工性和产品质量。着重研究了原液着色黏胶纤维的制备过程中,颜料与浆液/原液之间的相互作用。Wet treatment post-fiber processing such as dyeing,finishing and functioalization of fabrics results in the generation of a large amount of effluents of dyes and chemicals,creating an adverse impact on the environment and human health.Imparting the coloration and functionalization during the process of making the fiber itself is an effective solution practiced in the synthetic and regenerated cellulosicfiber industry to reduce this impact,e.g.dope dyeing,adding cationic dyeability etc.The challenges involved in the case of fiber level modifications in regenerated cellulose process like viscose are different from those encountered in synthetic fiber processes.Though commercial products based on fiber modifications are available,a gap exists in the understanding of additives-media interactions in the viscose process.This study has been initiated to bridge the gap and enable better processability and product quality in products made through fiber modification.In this specific article the focus is on pigment-slurry/dope interactions,during the process of making dope dyed viscose fibers.
