ABSTRACT:
A method of forming bicomponent fibers in a sheath-core relationship in a spinning pack that incorporates a plurality of adjacent plates that define predetermined flow paths therein for a sheath component and a core component to direct the respective components into the sheath-core relationship. The method comprises maintaining the differential pressure in the spinning pack between the sheath component and the core component low enough to avoid leaks and doglegging, while maintaining the total spinning pack pressure low enough to prevent leaks and doglegging.
