摘要
本文探讨了聚乙烯吡咯烷酮(PVP)对直接染料染色棉纤维的影响,测定了不同工艺条件下的上染速率曲线,并与非离子表面活性剂进行比较。结果表明,PVP有较强的缓染和匀染作用。通过测定染液吸收光谱等方法对聚乙烯吡咯烷酮与直接染料间的相互作用进行了分析。
The influence of Polyvinylpyrrolidon（PVP） on cotton dyeing process of direct dye was studied by the dyeing rate test in various processing parameters and comparison with non-ionic surfactant. The results showed that PVP had obvious retard-dyeing and leveldyeing effect. The interaction between PVP and direct dye was analyzed by absorption spectroscopy.
