Combined dyeing and resin finishing of wool/viscose and cotton/wool blends

Abstract

The objective of this study is to establish a single-stage process for anionic dyeing and easy-care finishing of wool/viscose (60/40) and cotton/wool (70/30) blended fabrics. Optimum conditions for maximizing dyeability and achieving high resiliency are: Fixapret (R) ECO (50 g/L), triethanolamine hydrochloride (20 g/L), ammonium persulfate (7.5 g/L) at 160 degrees C for 3 min. The extent of improvement in both the depth of shade and easy-care properties is determined by the nature of substrate and follows the descending order wool/viscose > cotton/wool. On the other hand, the extent of dye fixation and the change in fastness properties of the obtained dyeings are determined by the class of dyestuff.
