ABSTRACT:
Low viscosity ethylene acrylic copolymers and blends thereof with other fiber-forming polymers for spunbond and melt blown nonwoven applications. Ethylene/alkyl (meth) acrylate, especially ethylene/methyl acrylate copolymers are found to be suitable for fiber-forming operations, especially melt blowing when the melt index is at least about 10. Blends of the copolymer with other fiber-forming polymers are especially suitable for fiber-forming operations. The nonwoven products of the copolymers and blends of the invention show a good degree of elongation making them especially suitable for certain fabric applications and new uses. The nonwoven fabrics are comprised of fibers of the copolymers and blends, having a diameter of about 1-40 microns. Larger fibers may also be formed by various techniques.
