SPINNER FOR DUAL-COMPONENT FIBERS HAVING MULTIPLE EXITS FOR EACH INLET

摘要

Apparatus for making dual-component fibers (76) is provided and includes a spinner (60) having a peripheral wall (64). The spinner (60) includes orifices (90) located on the exterior of the peripheral wall (64) for centrifuging dual-component fibers (76), with the spinner (60) being divided into at least two compartments (88). The first and second molten thermoplastic materials are supplied to the spinner (60) and directed into alternate ones of the compartments (88) so that adjacent compartments (88) contain different thermoplastic materials. Passages (92, 93) are located in each of the compartments (88) through which the molten thermoplastic materials flow to the orifices (90) on the peripheral wall (64) of the spinner (60). At least some of the passages (92, 93) have branches (92a, 92b, 92c, 93a, 93b, 93c) which form a common inlet adjacent to the interior of the peripheral wall (64) and which communicate with at least two different orifices (90) on the peripheral wall (64) of the spinner (60).
