Title: NONWOVEN FABRICS MADE FROM POLYMER BLENDS AND METHODS FOR MAKING SAME
Abstract:
The present invention is directed to fabrics formed from the polymer blends. The polymer blends comprise from about 70 to about 99.9 wt%, based on the total weight of the composition, of a first propylene -based polymer and from about 0.1 to about 30 wt% of a second propylene based polymer. The first polymer has a melt flow rate of from about 100 to about 5,000 g/10 min, and the second polymer has a melt flow rate of from about 1 to about 500 g/min, and the second polymer has either a lower melt flow rate or a higher triad tacticity than the first polymer.
