PP COPOLYMERS FOR MELT BLOWN/PULP FIBROUS NONWOVEN STRUCTURES WITH IMPROVED MECHANICAL PROPERTIES AND LOWER HOT AIR CONSUMPTION

摘要

The present invention is directed to a new composite material comprising melt blown fiber based on a propylene copolymer and a fibrous substrate material, a process for the preparation of such a composite material, articles made therefrom as well as to the use of the propylene copolymer for the preparation of such a composite material or article and the use of the propylene copolymer for reducing the hot air volume during a melt blowing process.
