<p>A process is disclosed in which a layer of textile fibers is applied to an expanded net formed from foils and consisting of two components, one of which is superimposed upon the other and one of which has a softening temperature substantially different from that of the other, and heating the layered structure thus formed to the softening temperature of the component having the lower softening temperature. The process is characterized by the fact that in forming the expanded net, the component having the lower softening temperature is spread sufficiently to cause it to tear into separate scales or flakes, some of which adhere to the higher melting component, and some of which adhere to the textile fibers.</p> |
