Abstract

1530990 Fibrous tubes; method of forming IMPERIAL CHEMICAL INDUSTRIES Ltd 25 July 1975 [5 Aug 1974] 13321/78 Divided out of 1527592 Heading F2P A tube comprises polyurethane or fluorinated hydrocarbon fibres produced by electrostatic spinning. It may be used as a prosthetic device and is preferably formed by collecting the fibres on a rotating charged former. Tubes spun from solution may be strong enough without further treatment. Those spun from dispersions may be sintered. Dispersed polymers tend to produce spin to discrete particles. Hence one additional, fibre forming organic polymer is added to increase the viscosity of the dispersion and bond the particles together in the spun mat. Polyethylene oxide polyacrylmide polyvinyl pyrrolidone, polyvinyl alcohol, polystyrene and polymethylmethacrylate are specified. The fibre forming solution or dispersion may contain zirconium oxide, titanium oxide, chromic oxide, magnesium oxide or hydroxide or calcium oxide or hydroxide to render the fibres wettable. The fibres may have a diameter of 0À1 to 25 microns. Fibres of different diameter or composition may be applied from separate spinnerets in turn to form a non-uniform mat or together to form a uniform mat. The tube may have a thickness of 25 to 1500 microns, a pore size of 0À001 to 500 microns and a porosity as collected of 55 to 95%. In Example 1 polyurethane fibres were deposited upon a rotating metal tube 10 having a flexable foam sleeve 11 to form a 2 mm. thick tube which was peeled from the foam. In Example 3 PTFE fibres were deposited upon an aluminium mandrel, a reinforcing helix of nickelchrome wire wound on, a second layer of PTFE fibres applied, the tube sintered and the aluminium mandrel dissolved in NaOH. In Example 4 a glass helix was used.
