    1297617 Non woven fabrics CHEVRON RESEARCH CO 24 July 1970 [25 July 1969] 36123/70 Heading D1R Non-woven sheet material comprises continuous synthetic polymer monofilaments having elongated cross-sections with an aspect ratio (ratio of cross-section length to width) of between 2.9:1 and 8:1 disposed randomly and substantially discrete from each other except at cross-over points. Preferably the monofilaments are of crystalline stereoregular polypropylene and have substantially rectangular cross-sections and cross-sectional areas in the range 0.00005 to 0.008 mm<SP>3</SP>. The non-woven sheets may be prepared by extruding the synthetic polymer through appropriately shaped orifices partially cooling the resulting monofilaments, drawing the filaments with a pneumatic jet and depositing them on a collecting surface, suitably a screen to which suction may be applied. The non-woven sheets thus produced may be heat sealed, calendered bonded or needle punched to fuse the fibres together. Bonding with an unspecified adhesive and stitching are also mentioned. Other suitable synthetic polymers specified are crystalline polyethylene, poly-4-methyl-1-pentene, copolymers thereof, polyvinylchloride, polyethylene terephthalate and nylon.
