Abstract: PROBLEM TO BE SOLVED: To obtain an ion exchange film excellent in mechanical strength under a humid condition and having necessary ion conductivity in a membrane form by heat-treating a film-like material, which is formed from an aq. disper sion containing fine particles of fluoroplastic, an ion exchange polymer and a fluorine-containing surface active substance, at temp. equal to or higher than the m.p. of fluoroplastic. SOLUTION: An aq. dispersion containing fine particles of fluoroplastic, an ion exchange polymer and a fluorine-containing surface active substance is applied or spread on a support and dried to form a film-like material which is, in turn, heat-treated at temp. equal to or higher than the m.p. of fluoroplastic. Herein, the mean particle size of the fine particles of fluoroplastic is usually about 50 μm or less, pref., about 40 μm or less, more pref., about 30 μm or less. As the ion exchange polymer, a cation exchange fluoropolymer containing a fluorine atom and a cation exchange group is pref. As the fluorine-containing surface active substance, sodium or potassium perfluoroalkylsulfonate is pref.

Abstract: PROBLEM TO BE SOLVED: To obtain an artificial blood vessel excellent in suturing operability, tissue affinity and patency by forming protruding parts having a specific angle to the longitudinal direction o-f a tube to the outer surface of the tube and winding a long member having an outer diameter equal to or less than the height of the protruding parts around the gaps between the protruding parts. SOLUTION: A porous PTFE (polytetrafluoroethylene) tube 1 is heated to the thermal decomposition temp. of PTFE or higher to form cut, shrunk and/or decomposed removed parts to the outer surface of the tube 1 to form protruding parts 3 having apparently high density as compared with the tube main body part. A long member 6 such as a fluoroplastic monofilament is spirally wound around the outer peripheral surface of the porous PTFE tube 1 so as to be embedded in recessed parts. The protruding parts 3 form an angle of 45 deg. or more with respect to the longitudinal direction of the tube 1 and the long member 6 has an outer diameter having a size equal to or less than the height of the protruding parts 3 and is wound around the gaps between the protruding parts 3 adjacent at least in the longitudinal direction.

Abstract: PURPOSE:To obtain a readily producible drawn PTFE porous substance, having a specific fiber knot structure continuous in a netlike form, long fiber and an integral structure excellent in strength characteristics. CONSTITUTION:A polytetrafleuoroethylene porous substance having a microfibrous structure composed of fiber and knots connected with the aforementioned fiber. The fiber-knot structure is substantially formed from parts of long fiber extending from the front to the back surfaces and parts of short fiber. The above-mentioned parts of the short fiber are continuous in the network direction in the direction perpendicular to the orientation direction of the fiber in the porous substance and the thickness direction. The aforementioned porous substance is produced by forming an unsintered polytetrafluoroethylene mixture containing a liquid lubricant, uniaxially drawing the resultant formed product, providing a porous substance and heating one of surfaces at a higher temperature up to 50-300 deg.C than that of the other surface in heating both the front and the back surfaces at >=325 deg.C sintering temperature and imparting a temperature gradient to the front and the back surfaces. The heating time is 10-200sec. Long fiber having >=150mum average length and short fiber having
