Cross-Linked Silicone Films in Textile Finishing

Abstract

Dimethyl silicone imparted wrinkle recovery values of 250-285° to various types of fabric when the silicone was cross-linked as a film on the cotton. To enhance this effect, a small amount of cellulose cross-linking was carried out using dihydroxydimethylol ethyleneurea without added metal salt catalysts. Conditioned wrinkle recoveries of 288- 308° and wet recovery angles of 302-310° (W + F) were obtained. The combination treatment has been adapted to durable-press techniques. High crease retention and wash-wear ratings were obtained on sateen after 30-45 machine launderings, with major abrasion damage occurring only after 45 cycles. The application of cross-linked silicone by coating as well as impregnation methods was carried out prior or subsequent to differential (one-sided) cross-linking of fabric: High crease retention and wash-wear ratings after 30 launderings were obtained on twill by this means. Possible effects of these treatments on both the interior and exterior of the cotton fiber are discussed.
