Abstract
A two-ply 50/50 polyester/viscose spun yarn was textured by the twist-set-detwist process through simultaneous setting of the components. The setting methods employed were 1) heat-setting plus dry-crosslinking by the use of resins at high curing temperatures, and 2) solvent-setting plus wet- crosslinking by a solution of epichlorohydrin in tetrachloroethane. It is observed that while the mechanical properties and crimp-rigidity values of the yarns produced by the two methods are com parable, method 2 produces yarn with a higher wet retractability and a considerably higher dye uptake.
