Abstract

A method of making spun bonded fabrics from filaments of polymeric material is disclosed. Conventionally, spun bonded fabrics are made by extruding a polymer in molten form out of apertures in a spinneret plate to produce filaments, drawing these filaments away from the spinneret plate, blowing a flow of cooling air transverse to the filaments as they are drawn away from the spinneret, depositing the filaments as they emerge from the drawing device on a conveyor to form a mat of the filaments, and effecting treatment on the mat to connect the individual filaments together to form a fabric. In the inventive method, the filaments are drawn at a speed of greater than 400 metres per minute away from the spinneret, the apertures in the spinneret are approximately C-shaped so that the cross sectional shape of the extruded filaments is approximately C-shaped, and the cooling air flow is directed towards the open mouth of the C shape of the filament cross section.
