Abstract (en)
[origin: EP0260974A2] Biconstituent fibers consist essentially of polypropylene as a continuous phase having distributed therein 20 to 45 weight percent of linear low density polyethylene (LLDPE) fibrils as a dispersed phase arrayed in a substantially omni-directional splayed manner. The LLDPE has a melt flow rate of 12 to 120 g/10 mins (ASTM) and preferably a density of 0.92 to 0.94 g/cm<3>. The preferred alkylene comonomers of the LLDPE have 4 to 8 carbon atoms, especially 1-octene in an amount of 5 to 10 percent. Fibers of deniers below 30, preferably below 15, can be obtained and have improved tenacity and hand as compared to polypropylene fibers.
