    摘要: Elastic non-woven fabrics are disclosed which are made in a melt blown process or a spunbond process. The fabric is made from a thermoplastic polyurethane polymer mixed with a crosslinking agent to give high strength elastic non-woven fabric. The crosslinking agent is added to the polymer melt prior to the melt passing through the die which forms the individual fibers. Further processing the non-woven is also disclosed.

    摘要: A spin pack assembly for use in melt spinning elastic fibers. The spin pack assembly includes a circular breaker plate having a center aperture and several circular patterns of apertures with each circular pattern having a plurality of apertures. Each circular pattern is located concentrically about an axis of the center aperture. The apertures in the outer circular patterns have a greater diameter than the apertures in the inner circular patterns. The spin pack assembly also has a spinneret plate where the exit aperture of the spinneret plate is recessed in the body of the spin pack assembly.
