<p>A process for the reinforcement of flexible flat parts, especially top cloths for articles of clothing or linings for such articles, in which process said flat parts are first printed on one side with an aqueous crosslinkable dispersion paste by the photogravure printing process and then are electrostatically flocked preferably with fibrous flocks, the flocks adhering to the paste, whereupon the paste is caused to undergo a condensation reaction after prestabilizing it by heat coagulation or by predrying, while said condensation reaction is performed with substantial exclusion of incoming air, under pressure and in the temperature range from 90 DEG to 175 DEG C. The process is simple, fast to complete, and leads to non-yellowed products.</p> |
