Abstract
The influence of temperature, time, and alkali concentration on the reaction of cellulose with volatile epoxides has been investigated. Cross-linking of cotton or viscose rayon fabrics with epichlorohydrin vapor produced a high degree of wet crease recovery and some improvement in dry crease recovery. A simple method involving an after-cure following the vapor treatment has been found to effect substantial improvement in dry crease recovery. Reaction of cellulosic fabrics with butadiene diepoxide vapor results in a marked increase in both wet and dry crease recover}-. In contrast to liquid phase treatments, the reaction of cellulose with epoxides in the vapor state occurs very rapidly at elevated temperatures and this technique may be readily adapted to continuous methods of processing. The effects of the vapor treatments on certain physical properties of the fabrics are recorded. In the light of these data the types of reactions involved and the products obtained are discussed.
