ABSTRACT:
A tenacious polyethylene terephtalate filament nonwoven sheet having at least one smooth filmy surface layer, bulkiness, resistance to fuzzing by friction, and a high tear strength. In the smooth filmy surface, filaments forming the same surface layer are crushed flat and buried with each other at the crossing sections. The average roughness of the smooth filmy surface is 25.mu. or below. Accordingly, the nonwoven sheet has excellent printing effect and resistance to frictional fuzzing. In a layer next to the surface layer, a plurality of filaments adhere closely to each other and practically maintain the original from thereof. Accordingly, the nonwoven sheet has bulkiness and high tear strength.
