Polypropylene blends for non-woven fabrics |
摘要 |
The present invention provides polypropylene blends for use in the production of fibers and fabrics. The polypropylene blends according to the current invention comprise from about 85 to about 95 percent by weight of a propylene 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 bonding temperatures and wider bonding windows without the increased smoke generation associated with high solubles homopolymers.
