  • Method of making a web which is extensible in at least one direction
    Patent number: 6896843
    Abstract: A method includes the steps of co-extruding a first component and a second component. The first component has a recovery percentage R1 and the second component has a recovery percentage R2, wherein R1 is higher than R2. 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.

  • Method of making a web which is extensible in at least one direction
    Publication number: 20040041308
    Abstract: A method of forming bicomponent fibers into a web is disclosed. The method includes the steps of co-extruding a first component and a second component. The first component has a recovery percentage R1 and the second component has a recovery percentage R2, wherein R1 is higher than R2 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 as a forming wire, to form an accumulation of 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.
