Abstract:

In order to improve the wet rubbing fastness of fabrics in dark shade, the wet rubbing fastness improver assisted by copper particles was synthesized with butyl acrylate, methyl methacrylate and sodium dodecyl benzene sulfonate. Morphology and dispersion distribution of the wet rubbing fastness improver assisted by copper particles was analyzed by scanning electron microscope and particle size analyzer. It was found that the modified copper particles were assembled like a pomegranate in water. Mean particle diameter of the wet rubbing fastness improver assisted by copper particles is around 2472nm. Thus, application of the wet rubbing fastness improver on cotton fabrics dyed with reactive dyes was investigated. It was found that the wet rubbing fastness of cotton fabrics dyed with reactive dyes had increased 1～1.5 grades after the treatment of wet rubbing fastness improver, when reactive dyes concentration was at 6% and 8%(o.w.f) respectively.
