摘要

A method for forming on a cotton garment an ironed fold that is resistant to a plurality of subsequent washes and that is still retained by the garment after said washes, comprising, impregnating said garment with an aqueous emulsion of a mixture of a part of ethylene cyclic-formaldehyde urea resin and from one to two parts by weight, based on said resin, of a butadiene acrylonitrile copolymer having a monomer ratio of 55 parts of butadiene to 45 parts of acrylonitrile, extracting the excess emulsion of said garment, forming a fold in said garment and hot ironing said garment along the fold line to form a fold therein, and subjecting said garment to a temperature sufficient to cause the mixture to cure thereon, said garment treated about 5% by weight of cyclic ethylene-formaldehyde urea and from about 5 to 10% by weight of butadiene acrylonitrile copolymer on She, based on the dry weight of the garment.
