Abstract

Abstract Press-free garments are produced by treating a fabric with a mixture of (A) an aldehyde donor compound comprising an aminealdehyde compound and (B) a synergistic catalyst comprising (1) an acid salt of a primary aliphatic amine and (2) a quaternary ammonium salt of the formula: R-Y-CH2-NR1R2R3 X wherein R is an aliphatic hydrocarbon chain of 12 to 18 carbon atoms, Y is -CONH- or -O-, R1, R2 and R3 are alkyl groups or with the nitrogen atom form a substituted or unsubstituted heterocyclic ring and X is a halogen atom or mineral acid radical; or an alkylaryl N-alkyl sulfonamide. The treated fabric is then partially dried, cut, sewn, pressed and/or creased to form the garment and then cured at an elevated temperature; or dried, cured and then cut and sewn into the garment.
