1,234,782. Fibrillating orientated strips and films. COURTAULDS Ltd. 3 Oct., 1968 [4 Oct., 1967], No. 45108/67. Heading B5B. An orientated strip or film of a crystalline polymeric material which has been longitudinally orientated to render it fibrillatable is fibrillated by moving it longitudinally past a plurality of fluid jets together extending trans. versely of the moving strip or film and directed at the strip or film. The fluid jets may issue from one or more lines of jet holes aligned transversely across the strip or film. Each line of jet holes may extend across the whole width of the strip or film and may be aligned at right angles to the longitudinal axis of the strip or film. The strip or film may be held under tension against the jet holes as it is moved past them. The fluid jets may be liquid or gaseous but are conveniently jets of air issuing from a line of jet holes aligned transversely across the strip or film. The strip or film may be made of polypropylene. The fibrillated strip or film may be twisted to form a twine or may be chopped transversely to form staple fibres. In the illustrated example a strip 1 (Figs. 1 and 2) of transparent crystalline polypropylene film is stretched in the longitudinal direction at a stretch ratio of 10 : 1 at a temperature of 150‹ C. to a stretched size of 0À5 inch width and 0À002 inch thickness. The strip is then passed in the direction of the arrow A over the face 2 of a jet head 3 at a speed of 100 metres per minute, being pressed against the face 2 by the tensioning rollers 4 and 5. At the same time air at a pressure of 40 p.s.i. is passed into the chamber 6 of the jet head 3 through inlet pipe 7 and emerges from the chamber 6 through two lines of jet holes 8 and 9 in the face 2 as a series of air jets. The holes are 0À005 inch in diameter and are spaced apart in each line by 0À01 inch. As the strip 1 is passed over the lines of holes 8 and 9, the air jets burst through the readily fibrillatable strip to cause the ...

Improvements in or relating to processes for making bulked yarns by the fibrillation of thermoplstic films

1,267,298. Fibrillating films. HERCULES Inc. 29 April, 1970 [6 May, 1969], No. 20709/70. Heading B5B. A process for forming continuous filaments by fibrillating a film and simultaneously bulking the filaments involves feeding a ribbon of longitudinally oriented thermoplastic film having longitudinal parallel striations (Fig. 3) at a predetermined speed, surrounding the ribbon with a jet of fluid at a temperature sufficient to plasticize the ribbon without loss of orientation and directing the fluid jet, and thus the ribbon, into a bulking chamber having an open end opposed to the fluid jet and a cross-sectional area sufficient to permit limited lateral movement of the fluid jet. A screen is moved laterally across and in close proximity to the open end of the chamber at a substantially slower speed than the speed at which the ribbon is fed into the chamber and by thus confining the fluid jet to exhaust through the screen randomly deflects the jet and hence the ribbon laterally within the chamber at a rapid rate and thereby fibrillates the film. The resulting filaments are folded on to the screen and are randomly crimped as they are moved out of the chamber by being compressed against the surface of the screen. Suitable apparatus for the process of the invention is that of U.S. Patent 3,457,611, Figs. 1 (not shown), and 2 in which striated ribbon R is fed through yarn-tube 15 and urged into bulking chamber 14 by a fluid jet, which may be steam under pressure, supplied to capillary tube 13 by way of channels 12, chamber 29 and supply pipe 30, 31. The ribbon is substantially completely fibrillated in chamber 14 by random rapid lateral movement induced by deflection of the jet, and thus the ribbon, from areas of the slowly moving screen 3 which are densely covered with fibrillated filaments to areas which are less densely covered. The filaments then pass under the lower surface 35 of the jet unit 2 and are randomly crimped by the pressure of the jet unit on the screen 3. ...

Multi-layer products

Fibrous products, including single fibers, yarn and fibrous webs, of improved fineness are produced from extruded sheet material extruding in the form of a sheet-like, multi-layer composite stream a plurality of extrudable materials, at least one of which is a synthetic thermoplastic fiber-forming polymer and another of which is removable by mechanical, chemical, or solvent action or a combination thereof, which layers extend generally parallel to the faces of said stream, with each such layer containing either said fiber-forming polymer or said removable extrudable material with the different layers being interspersed in said composite stream; solidifying this composite stream into a multilayer sheet, then splitting the resultant solid sheet to convert the same into a coarse fibrous product, and treating the thus produced fibrous product by mechanical, chemical, or solvent action or a combination thereof to at least partially remove the removable extrudable material and produce a fibrous product of increased fineness. Instead of solidifying the extruded stream while intact, the stream can be divided during extrusion along spaced generally parallel planes extending through the stream at an angle to its faces and solidified in this divided state to form separate strips each containing a section of the multi-layer composite stream. These separate strips are then treated as indicated to at least partially remove the removable material and at least partially separate the polymeric layers therein.
