IPC: D04H1/46
Filed: 1970-05-13
Abstract: 1304603 Non-woven fabrics KURARAY CO Ltd 13 May 1970 [13 May 1969 16 May 1969 25 June 1969 (2)] 23208/70 Heading D1R A non-woven web is prepared by passing a filament tow or staple fibre bundle through a passage 6 equipped with two rows of oppositely directed jets 7 located one on each side of the fibre bundle, said rows of jets extending transverse to the direction of travel of the fibre bundle and across the width of the passage, the holes in one row being aligned with those in the other, and blowing a fluid, e.g. air or steam, on to the fibre bundle in order to interlock the fibres. The rows are spaced at least 3 mm apart and are constituted by a line of holes 0.5 mm to 1.0 mm in diameter at a spacing between adjacent edges of 0.5 mm to 2 mm. Just before the fibres are interlocked by the fluid jets, the fibres of the upper and lower layers are oriented at an angle to the direction of travel in order to enhance the lateral strength of the web, the fibres of the middle layer remaining orientated parallel to the direction of travel. The exterior layers are orientated by one or more fluid jets 19 placed above and below the fibre bundle 8 and directed laterally towards the bundle. Alternatively the layers may be orientated by rotating spiral screw brushes placed above and below the fibre bundle. Transverse orientation may be aided by a 5-10% overfeeding, caused by take-away rollers (11, Fig. 6, not shown) having a lower circumferential speed than supply rollers (9). This increases the width of the web. The differentiation in transverse orientation may be enhanced by forming the web from three layers that are supplied using different degrees of overfeeding. The plates 2, with their rows of entangling jets may be twice the width of the web, and reciprocated transverse to the direction of movement of the web, so as to produce a zig-zag fibre alignment (Fig. 13, not shown). The web may contain binder.
