Abstract
A method includes the steps of co-extruding a first component and a second component. The first component has a recovery percentage Rand the second component has a recovery percentage R, wherein Ris higher than R. The first and second components are directed through a spin pack to form a plurality of continuous, molten fibers. The plurality of molten fibers is then routed through a quenching chamber to form a plurality of continuous cooled fibers. The plurality of continuous cooled fibers is then routed through a drawing unit to form a plurality of continuous, solid linear fibers. The linear fibers are then deposited onto a moving support, such ass a forming wire, to form an accumulation or fibers. The accumulation of fibers are stabilized and bonded to form a web. The web is then stretched by at least 50 percent in at least one direction before being allowed to relax. The relaxation of the web causes the fibers to acquire a 3-dimensional, coiled configuration which provides the web with extensibility in at least one direction.
