POLY(TRIMETHYLENE TEREPHTHALATE) BICOMPONENT FIBER PROCESS |
摘要 |
A process of making side-by-side or eccentric sheath-core bicomponent fiber (6) wherein each component includes a different polytrimethylene terephthalate composition. Quench gas (1) enters a zone (2) below a spinneret face (3) (which spinneret face (3) is recessed above the top of the zone(2) by a distance (A)) through a plenum (4), past a hinged baffle (18) and through screens (5), resulting in substantially laminar flow across still-molten fibers (6). The fibers (6) leave the zone (2) through an exit (7) and finish can be applied by a finish roll (10). |
