ABSTRACT:
The present invention relates to a die for use in textile processes involving nonwoven melt blown fabrics. In a melt blown process, molten polymer resin is injected into a melt blown die and ejected from the die in the form of filaments. The present invention is directed to an improved die nosepiece comprising a multiplicity of adjacent holes offset with respect to each other at an angle greater than or equal to 5.degree. and less than 90.degree., through which resin filaments are ejected.
