Abstract:
1. A method of forming fibers into a web, comprising the steps of: a) co-extruding a first and a second component, said first component having a recovery percentage R b) directing said first and second components through a spin pack to form a plurality of continuous molten fibers each having a predetermined diameter; c) routing said plurality of molten fibers through a quench chamber to form a plurality of cooled fibers; d) routing said plurality of cooled fibers through a draw unit to form a plurality of linear fibers each having a smaller diameter than said molten fibers; e) depositing said linear fibers onto a moving support to form an accumulation of fibers; f) stabilizing and bonding said fibers to form a web; g) stretching said web in at least one direction by at least 50 percent; and h) allowing said stretched web to relax whereby said fibers acquire a 3-dimensional, coiled configuration which provides said web with extensibility in at least one direction.
