Process for imparting water repellancy to fibrous cellulosic textile materials by acylating with isopropenyl esters |
摘要 |
Water repellancy is imparted to fibrous cellulosic textile material by applying to it, for a very short period of time, an isopropenyl ester containing a catalytic amount of an acid catalyst and then heat curing the treated material. Excellent water repellancy is obtained at a very low degree of substitution and a high degree of retention of tensile strength.
