Abstract
The cross-linking of cotton fabric with several N-methylol finishing agents in combi nation with an additive, the dimethyl ether of tetraethylene glycol, was investigated in an effort to obtain wrinkle-resistant and wash-wear cotton fabrics that retain an ability to swell with water. By proper adjustment of the concentration of this additive in the pad bath, it is possible to obtain finished fabrics with moisture regains equal to or even greater than untreated cotton, while maintaining good wrinkle resistance and wash-wear appearance. Wet crease recovery is slightly increased and dry crease recovery is slightly decreased by the use of the additive. Chlorine resistance and the relationship of breaking strength to crease recovery are unaffected. The inclusion of this additive in the treating bath formulation appears to alter hoth the length and distribution of the cross-links formed.
