TEXTILE-LIKE RETICULAR PRODUCT DERIVED FROM FILM MATERIAL

摘要

A two-dimensional integral net (1) having a nap in form of relatively long fibers (3) integral with the net and protruding from the edges which surround the apertures (2) of the net. A method of producing this net from a film comprises heating selected areas of the film to a molten state and dragging out this molten material into fibres to leave apertures in the film while controlling the fibre-dragging by cooling with an air jet.
