A method for producing crimped textile elements by extruding a bilaminate film each face of which comprises a different thermoplastic macromolecular polymer and one face of which comprises a mixture of such a polymer with a vinyl copolymer, orienting the bilaminate film by stretching, and then fibrillating the oriented film. The fibrillated film may be chopped into discontinuous fibers. The crimped products include fibrillated webs or sheets, continuous filaments and short fibers. |
