Abstract: 1,149,631. Film fibrillation. PLASTICISERS Ltd. 12 April, 1966 [13 Jan., 1965], No. 1490/65. Heading B5B. [Also in Division D1] A continuous elongated irregular network of interconnected fibrils is formed by longitudinally folding a longitudinally orientated strip, tube or sheet of a polyalkylene or a mixture of polyalkylene, e.g. polyethylene and/or polypropylene, so that the strip &c. shatters or splits into a fibrillated structure. The strip &c. material may be formed from an intimate mixture of fibre-forming polymers of two or more different and normally incompatible types, e.g. polyethylene and polystyrene. Polyalkylene(s) may be mixed with polyamides or polyesters, e.g. polyhexamethylene adipamide or polyethylene terephthalate. The strip &c. may be a cellular film produced by incorporating into the mix (which is to be extruded through a fish-tail die) a blowing agent, e.g. a chemical compound which decomposes to form gaseous products, a carrier such as carbon black containing absorbed or adsorbed inert fluid, such as water, gaseous at the temperature of the die-head, or an inert liquid such as water. Orientation is effected by continuously drawing the heated strip &c., with a stretch ratio of 6 : 1 to 15 : 1. The strip &c. subsequently to or concurrently with the folding thereof, may be passed over, round or under and in contact with an edge or edges whilst under tension so as to bend the strip sharply and accentuate the fibrillation. Folding is effected by passage of the strip &c. over, round, under or through a guide member which is shaped to cause the folding and traverses the bobbin on which the strip &c. is collected. The network may be twisted, plied and/or cabled to form yarn, twine, cord or rope.
