Abstract
As the acrylic polymers were the origin of the high soil-retentive property of the resin finished fabrics, high polymer electrolytes, such as Na-CMC (P1), Na-alginate (P2), copolymer of vinylmethylether and maleic-anhydride (P3), copolymer of vinylacetate and Na-maleate (P4) were added to dimethylol-ethylene-urea (DMEU) for the treatment, for the purpose of improving the soil-resistance and detergency of the resin finished fabrics*.
All these polymers, P1_??_P4 showed excellent improving effects on the above mentioned properties, but the fabrics treated with the mixtures of DMEU and these polymers had less wrinkle-recovery than those treated with DMEU and ordinary acrylic polymers.
By the conductivity measurements, the cause is to be found in the reaction of DMEU with the polymers, especially mith P3 and P2, and the consumption of DMEU in a solution for treatment led to a decrease in effective DMEU for cross-linking which may be recognized as the cause of high wrinkle resistance. Then a more useful method of combination must be found to attain both the soil-resistance and the wrinkle-resistance.
