摘要：
This invention relates to improved polypropylene nonwoven fabrics. The fabrics are made from isotactic polypropylene which has been produced with a catalyst systems comprising at least two metallocenes. These nonwoven fabrics, particularly when prepared using a spunbonding process, exhibit significantly improved strength without significant sacrifice of other favorable properties.
