BEHAVIOR OF CELLULOSIC FABRICS TREATED BY THE POLY-SET PROCESS

Abstract

Cellulosic fabrics (cotton, polynosic and spun rayon) were treated by the Poly-Set, two-step resin finishing process, using MMM, DMEU or their mixtures as finishing components and zinc acetate and zinc nitrate as polymerization (first step) and cross-linking (second step) catalysts, respectively.
The effect of each process on the dry and wet wrinkle recovery angles was investigated.
The alkali swelling of spun rayon was decreased most significantly by the resin finishing. DMEU was more effective than MMM to decrease the alkali swelling of the fabrics by the treatments.
The relationship of the amount of crystal regions and the dimension of crystallite to the restrictional tendency on alkali swelling behaviors is discussed.
