DRAWN AND SPINNABLE THERMOPLASTIC HOLLOW FIBER AND NON-WOVENFABRIC CONTAINING THIS

摘要

PURPOSE: To prevent hardening in folding fabrics as a component of absorbing fiber surface structure and to prevent the interruption of liquid transportation by providing an aperture which is interrupted parallel to a longitudinal axis of a thermoplastic hollow fiber in a specified state. CONSTITUTION: An aperture interrupted parallel to a longitudinal axis of a thermoplastic hollow fiber is provided and a longitudinal virtual axis within a fiber cavity is enclosed within an essentially curved concave by an outer film of the fiber at a range of at least 90 degree.
