A novel treatment for multifunctional finishing and reactive dyeing of polyamide-6-cotton blend

Abstract

A new approach to simultaneous functional finishing and reactive dyeing of polyamide-6-cotton fabric (50/50) is developed. The extent of improvement in the functional and dyeing properties is determined by the UV-absorber, UV-Sun(R) CEL, concentration, type and concentration of the used reactive dye as well as the treatment sequence. The UV-protection and the antibacterial properties, against S. aureus (G+ve) and E. coli (G-ve) bacteria, of the simultaneously finished and dyed fabric samples are maintained even after 15 washing cycles. After 15 washing cycles, the depth of shades and the fastness properties of the obtained dyeings are not seriously affected. The incorporation of the used UV-absorber onto the blend fibres was also confirmed by SEM analysis.
