Abstract
Raised prints and graphic designs on fabrics which can safely and effectively be drycleaned and washed are provided by formulating a cross-linkable polymer printing medium with about 1 to 45 weight percent thermally expandable microspheres, applying said medium to a fabric, heating at a temperature of about 180.degree. to 250.degree. F to expand the microspheres and cross-link the polymer, and then curing for about 1 minute at a temperature of about 300.degree. F.
Claims10
The method of forming a washable and dry-cleanable foamed print on a washable and dry-cleanable fabric substrate comprising selectively applying to said substrate a printing composition comprising an adherent film forming cross-linkable polymer binder in a liquid vehicle therefore, said composition containing about 1.0 to 45 weight percent, based on the weight of said binder, of thermoplastic, thermally expandable microspheres about 0.5 to about 300 microns in diameter;
- drying to remove said liquid vehicle to form a dispersion of said microspheres in said binder;
- heating to expand said microspheres and cross-link said polymer binder to form a raised and textured surface;
- and curing the cross-linked polymer binder at a temperature of about 300.degree. F for a period of about 1 to 3 minutes.
