The Influence of Acid Dyes on Stiffness and Crease Recovery of Nylon Fabrics

When nylon fabrics were dyed with acid dyes, stiffness and crease recovery changed due to the adsorption of dyes. Stiffness increased, while crease recovery decreased with increase in dye content. However, neither stiffness nor crease recovery of dyed nylon fabrics varied with the kind of dyes. It was considered that nylon fabrics stiffened and that crease recovery decreased because of the dynamic restriction of nylon molecules due to the adsorption of dyes. It could be said that influence of the restriction on the stiffness and the crease recovery mostly depended on the dye content rather than kind of dyes.
