Abstract
1392667 Olefin polymer fibres MONTECATINI EDISON SpA 26 Feb 1973 [25 Feb 1972 30 Jan 1973 1 Feb 1973] 9258/73 Heading B5B [Also in Division D2] Olefin polymer fibres suitable for use as pulp in paper-making are made by ejecting a solution of an olefin polymer as a jet, and hitting the jet of of solution with a jet of fluid, the jets suitably being inclined to each other at 30-90 degrees. Polyethylene, optionally containing minor proportions of copolymerized monomers, and isotactic polypropylene are preferred, and the solution may also contain a polymer containing polar groups. Specified fluids include water, air, steam, carbon dioxide, nitrogen and oxygen, and the speed upon impact of the fluid jet may be 200 to 600 m/s. The polymer solution which may contain a surfactant may be ejected into the ambient atmosphere, suitably at a speed of 1,000 to 2,000,000 m/h. Preferred solvents include heptane, hexane and trichlorofluoromethane, (many others are listed); desirably the temperature of the solution is at least 60 C. higher than the boiling temperature of the solvent under normal conditions, and the boiling point of the solvent should exceed the melting point of the polymer. In apparatus as shown, an olefin polymer solution is fed through pipe 1 into an autoclave 2 fitted with stirrer 3, and ejected as a jet through a nozzle 6. Hitting fluid is fed through a pipe 4 and a nozzle 5. The fibres fall into collection vessel 7. The nozzle is shown in greater detail in Fig. 2 (not shown). In an alternative embodiment the fluid may be in the form of a mass which is geometrically coaxial with the nozzle ejecting the polymer solution. Thus in Fig. 3, duct 11 for polymer solution is arranged coaxially inside a duct 12 for hitting fluid. Ducts 11, 12 respectively end with nozzles 13, 14. Frusto-conical chamber 15 allows the polymer solution to expand before being hit. Terminal zones 16, 17 of ducts 1, 2 are so shaped that the axis of the space 18 between them is inclined at an angle α to that of the nozzle 13. Examples illustrate the manufacture of polypropylene fibres from solutions in hexane, polyethylene fibres from solution in hexane, heptane or trichlorofluoromethane; and of fibres of a blend of polyethylene with either an ethylene-ethyl acrylate copolymer or polyvinyl chloride, both from hexane solution.
