ABSTRACT:
There is disclosed a three dimensional nonwoven web consisting of drawn and unoriented thermoplastic fibers formed from a blend of polypropylene and polybutylene, wherein the blend by weight is from 90% to 70% polypropylene and from 10% to 30% polybutylene. The blend can be a blend of a homopolymer of polypropylene and a homopolymer of polybutylene; a homopolymer of polypropylene and a copolymer of polybutylene; a copolymer of polypropylene and a homopolymer of polybutylene; and a copolymer of polypropylene and a copolymer of polybutylene. In addition, ternary blends comprising polypropylene, polybutylene, and terpolymer (propylene, ethylene, and 1-butene) are useful. The resulting nonwoven webs have enhanced strength, toughness, and tear resistance.
