PLASTICALLY DEFORMABLE NONWOVEN WEB |
摘要 |
A nonwoven web formed of substantially continuous spunmelt fibers is formed from a homopolymer of polypropylene having a skewed molecular weight distribution and a polydispersity of less than 3.5. The web, when subjected to high speed incremental deformation, is plastically deformed and characterized by, e g., a tensile strength at 400% elongation which is at least 10% of the peak tensile strength, a tensile strength at 250% elongation which is at least 40% of the peak tensile strength, and a ratio of the viscoelastic deformation energy after the peak tensile strength to the viscoelastic deformation energy before the peak tensile strength which is greater than one. |
