Document Type and Number:
Japanese Patent JP2002544398
Kind Code:
A
Abstract:
A three-dimensionally crimped spreadable continuous filament tow band is made by extruding polymers through a capillary, spinning the extruded polymers into filaments to form fibers, quenching the fibers, grouping the quenched fibers together to form two or more separate ropes, drawing the separate ropes simultaneously to form flat ribbons, stacking the flat ribbons on top of each other to form a single uniform tow band, and removing tension from the band. The batting produced by deregistering and spreading the tow band uniformly is useful, for example, to make filled articles, such as sleeping bags, duvets, and pillows.
