POLYPROPYLENE BLENDS FOR NON-WOVEN FABRICS

摘要

The present invention provides polypropylene blends for use in the productio n fibers and fabrics. The polypropylene blends according to the current invention comprise from about 85 to about 95 percent by weight of a propylen e homopolymer and from about 5 to about 15 percent by weight of an ethylene/propylene random copolymer having an ethylene content of about 7 percent by weight or less. The overall ethylene content of the blends according to the present invention is about 1 percent by weight or less. Polypropylene blends according to the current invention provide lower bondin g temperatures and wider bonding windows without the increased smoke generatio n associated with high solubles homopolymers.
