Abstract
A process for producinga wash-durable finish on a textile is provided which comprises applying to the textile an effective amount of: A. at least one free-radical polymerizable monomer having a functional group capable of undergoing an acid catalyzed condensation reaction with B. at least one co-reactant having a reactive methylol, hydroxy, alkoxy or amino group capable of undergoing acid-catalyzed condensation with a reactive group on said free radical polymerizable monomer; C. at least one free radical generating catalyst and at least one acid catalyst, or at least one catalyst having both free radical generating and acidic characteristics, and D. subjecting said textile to curing conditions to conjointly effect free radical polymerization and acid-catalyzed condensation reactions.
Claims11
A process for producing a washdurable finish on a textile which comprises applying to the textile an effective amount of:
- a. at least one free radical polymerizable monomer selected from the group consisting of acrylamide, methacrylamide, N-methylolacrylamide. N-methylolmethacrylamide. N-(alkoxymethyl) acrylamide, diacetone-acrylamide, the methylolated products of diacetoneacrylamide, 2-hydroxyethylacrylate and 2-hydroxyethyl methylacrylate;
- b. at least one co-reactant having a reactive, hydroxy, alkoxy or amino group capable of undergoing acid-catalyzed condensation with a reactive group on said free radical polymerizable monomer (a) provided that said co-reactant is not the same as said free radical polymerizable monomer;
- c. at least one free radical generating catalyst and at least one acid catalyst, or at least one catalyst having free radical generating and acidic chracteristics, and
- d. subjecting said textile to curing conditions to conjointly effect free radical polymerization and acid-catalyzed condensation reactions.
The process as defined in claim 11 wherein sulfur dioxide is employed as the catalyst activator.
