SOFT AND ELASTIC NONWOVEN POLYPROPYLENE COMPOSITIONS

摘要

This invention relates to a nonwoven fabric having a first component of from 5% to 99% by weight based on the total weight of the composition wherein the first component is selected from the group consisting of homopolymers of propylene and random copolymers of propylene, the first component having a heat of fusion as determined by DSC of less than 50 J/g and stereoregular propylene crystallinity; and a second component having from 95% to 1% by weight based on the total weight of the composition of a propylene polymer or blends of propylene polymers; wherein the nonwoven fabric has a permanent set of less than 60%.
