A polyvinyl chloride foam obtained by beating a plastisol is reinforced by incorporating textile fibers into the foam, before, during or after emulsification of the foam in a mechanical beater. The fibers may be natural or synthetic textile fibers such as superpolyamides or polyesters and they are from 1-2 deniers, 0.1-6 mm. in length and present in an amount between 2 and 20 percent by weight in the plastisol. Imitation leather is produced from these foams by joining two layers thereof together, one layer being of lower density but having a greater quantity of fibers therein per unit weight of the plastisol. |
