Abstract

Previous works showed that the UV technology could be used in wool printing. Considering that dye has different behavior in printing paste and dyebath, the structure and dyeing properties of wool treated by UV radiation were studied in this research work. The wool samples were exposed to UV radiation for 60 min, and the superficial modification of wool fiber was investigated by XPS. Chemical change of UV treated wool was classified as surface oxidation of cystine residues and thereby induce the change in dyeing properties of wool. Dyeing tests of UV treated and untreated wool samples were performed at low temperature of 45oC, 50 oC, 55 oC and 60 oC, and UV treated wool samples showed remarkably higher rate of dye uptake compared with untreated samples. Adsorption behavior and diffusion coefficient were also studied. It was considered that the enhancement of dyeing properties of wool with the UV radiation treatment was due to the increased diffusion coefficient of wool fibers.
