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.
