Abstract
PURPOSE:To obtain a hollow yarn module generating a very small amt. of leached matter and having superior chemical and heat resistances by forming all the constituent members of the module with a tetrafluoroethylene polymer. CONSTITUTION:Liq. stock prepd. by uniformly mixing an aq. dispersion of a tetrafluoroethylene polymer with a fiber forming polymer such as sodium alginate is spun from a spinneret together with a core liq. and solidified in a solidifying liq. The resulting hollow yarn is heat treated, immersed in a sulfuric acid-nitric acid mixed soln. and allowed to stand to remove the fiber forming polymer from the hollow yarn and to make the yarn porous. Pieces of such porous hollow yarn are bundled and the tip of the bundle is dipped in an aq. dispersion of said tetrafluoroethylene polymer and dried. By repeating the dipping and drying, a resin coat is formed on the surface of the hollow yarn. The coat part of the bundle is then clamped with a tetrafluoroethylene polymer film and only the end is heated to melt the polymer and to fix the hollow yarn. The bundle is incorporated into housing made of said tetrafluoroethylene polymer and the housing is heated to fix the bundle by melting.
