Abstract: Texturing of polyester-viscose blended yarn has been accomplished through heat setting of polyester and crosslinking of viscose by a single-stage rapid cure technique. Two resins, Finish KVS new (Sandoz) (dimethylol dihydroxycthy1cne urea based resin with built-in catalyst) and resin U-4750(BASF) (a polyfunctional urethane resin) were used as crosslinking agents for setting the deformation. The efficiency of both the resins has been studied as a function of curing period, temperature and catalyst and resin concentrations. It is observed that a curing temperature of 210-220oC and a curing period of 30 see are optimum for both the resins. With lesser amount of resin + catalyst in the padding bath, KVS gives a stronger yarn than U-4750 resin for an equivalent crimp rigidity value.
