Abstract: To the surface of knitted cotton fabrics is applied from 20 to 90% wet add-on of crosslinking agent in a novel geometric pattern by any of several techniques including kiss-roll padding, printing, or transferring the solution of crosslinking agent from impregnated material to the surface of the knitted fabric, followed by drying and curing the moist textile at elevated temperatures, and finally by washing the cured fabric to effect differential shrinkage of the fabric in the applied design, which novel shrinkage in the fabric is fixed through the life of the fabric and is stable through subsequent launderings.

Abstract: The instant invention relates to a method for the preparation and isolation of anhydrous crystalline dimethylolated methyl-, and ethyl carbamate by lyophilization. Further, the instant invention is a dimethylolated methyl-, and ethyl carbamate, the chemical entity of which consists of an increased formaldehyde to nitrogen ratio, which is essentially free of free formaldehyde.The dimethylol methyl-, and ethyl carbamates are represented by the general formula ROCON(CH.sub.2 OH).sub.n, with n being 2, and in which R is an aliphatic or modified aliphatic group.
