Dyes with high chlorine-resistant fixation property for quick-drying PVA fabric

LIU Yong-gan;LUO Yan;College of Chemistry, Chemical Engineering and Biotechnology, Donghua University;  
Quick-drying PVA fabric features poor chlorine-resistance. Acid dyes, reactive dyes and neutral dyes are selected respectively to dye PVA fabric based on its texture and molecular structure, and then the chlorine-resistant fixing agent is adopted to carry out the comparison tests. The surface morphology of the fabric and dye uptake, fixation property, washing fastness, and chlorine-resistant fastness of the dyeings are measured by SEM, double-beam UV-Vis spectrophotometer and color matching instrument respectively. The results show that the quick-drying PVA fabric exhibits porous structure of inner cavity.Neutral dyes and acid dyes have higher affinity to the PVA fabric than the reactive dyes, while the affinity of neutral dyes to the PVA fabric is little better than that of acid dyes. Moreover, chlorine-resistant fixing agent can improve chlorine-resistant fastness of the PVA dyeings.
