Abstract

WOS: 000267356700009 This study is about environmentally safe pre-treatment for wool fabrics to improve their printability with acid dyes. Knitted wool fabrics treated with argon and air atmospheric plasma Were evaluated ill terms of printability. Printing was carried out with two different receipts under different steaming conditions. The surfaces of untreated and plasma treated wool fabrics were analyzed by SEN to compare the morphological changes, Hairiness of the fabric was investigated tinder light microscope, The results showed that atmospheric plasma treatment improved the hydrophility of the fiber and enhanced the adhesion and penetration of printing paste to the Surface with decreasing hairiness. Increased penetration of printing paste and reduced hairiness caused higher color yield even at lower steaming durations without wetting agent. Air and argon plasma treated fabrics, especially at higher exposure durations, showed higher light fastnesses. Adversely, same samples showed a decrease in wet and dry rubbing fastnesses which were probably caused from the deeper shade of the fabric.

Abstract

Knitted wool fabrics were treated with atmospheric argon plasma, enzyme (protease), chitosan and a combination of these processes. The treated fabrics were evaluated in terms of their dyeability, colour fastness and shrinkage properties, as well as bursting strength. The surface morphology was characterised by SEM images. In order to show the functionalisation of a wool surface after plasma treatment, XPS analysis was done. Our results reveal that atmospheric plasma has an etching effect and increases the functionality of a wool surface, which is evident from SEM and XPS analysis. Atmospheric plasma treatment enhances the adhesion of chitosan to the surface and improves the hydrophility of the fibre. Enzymatic treatment improves the coating ability of chitosan. All these processes produce high dyeing efficiency and shrink-resistance in wool fabric. Plasma treatment has no significant effect on bursting strength, unlike enzymatic treatment. The loss of bursting strength after plasma and enzymatic treatment is recovered, to a certain degree, by chitosan treatment. Significant changes in the fastness properties of the treated fabrics were not observed. [ABSTRACT FROM AUTHOR]
