ABSTRACT:
A method for producing a flocked web by applying a layer of a thermosetting plastic foam onto a carrier sheet which foam penetrates into the surface of the carrier, flocking the uncrosslinked layer and then thermally hardening the layer and wherein prior to complete crosslinking of the flocked layer, the partially crosslinked flocked layer is submitted to heat pressing. In a preferred embodiment, the heat pressing can include an embossing step. The process of the present invention is not only easy to carry out, it avoids the presence of air bubbles as well as other inconsistancies in the product. The product obtained with the present invention is also disclosed.
