Abstract
PURPOSE: Elastic filaments that are composed of two polymer blocks, i.e., a polyolefin and an elastomer, thus has moderate flexibility and toughness, good selfcrimping property and shows high elastic recovery.
CONSTITUTION: The elastic filaments are composed of (A) a polyolefin such as crystalline polypropylene and (B) a thermoplastic elastomer such as ehtylenepropylene elastomer wherein the cross section resulting from cutting the filament in the direction vertical to the fiber axis consists of polyolefin phase blocks and elastomer phase blocks and the total number of these blocks are less than 20 on the average.
