摘要： A quench bath, for quenching and solidifying an extruded hollow porous fiber of a liquid polymer solution in a chemical quenching solution, includes a shallow quench bath of a length for the generally horizontal part of the extruded fiber travel in the bath. A vertical extension tube with its lower end beneath the surface of the bath liquid holds a spinneret through which the fiber is extruded. The spinneret is sealed in the tube above the height of the liquid in the shallow bath. A vacuum drawn in the tube raises the liquid up to the spinneret. Also, the vacuum may be drawn by disposing the spinneret in a sealing piston which is raised through the tube to draw the vaccum in the tube behind the piston.

摘要： A method is provided of manufacturing a skinless, nylon microporous hollow fiber membrane. The method comprises the steps of providing a nylon polymer dope solution and a quench liquid capable of solidifying and forming micropores in an extruded nylon polymer dope solution to produce a skinless, microporous nylon membrane. The quench liquid is placed into a vessel and a tube is provided which has a top and a bottom outlet. The bottom outlet of the tube is partially submerged in the quench liquid, the tube vertically extending therefrom. A spinneret is provided which has an outlet adjacent the top of the tube. The chemical quench liquid is raised in the tube until it is in substantial contact with the spinneret outlet. The nylon polymer dope solution is extruded in the form of a hollow fiber through the spinneret outlet directly into the quench liquid. Extruded hollow fiber is then passed down through the tube and into the vessel, whereby the quench liquid solidifies and forms micropores in the extruded nylon polymer dope solution to thereby form a skinless nylon microporous holow fiber. The fiber is then redirected in the vessel in a generally horizontal direction through the vessel.

摘要： A method for the production of a hydrolytically stable nylon membrane includes providing a nylon having at least about 0.9 moles of amino end groups per mole of nylon and preparing the nylon membrane therefrom. The membrane can be used in cartridges for use in filtration applications as may be necessary in the food and beverage industry as well as for the production of pharmaceuticals and the manufacture of electronic components. The membrane is capable of withstanding autoclaving and hot water sanitization without molecular dissociation regardless of its pore size, or thickness of the membrane, or the nylon solids content of the dope or, the temperature at which the dope is made.

摘要： A microporous nylon hollow fiber is prepared by extruding a nylon spinning solution through an annular slit of an orifice into a quench liquid while simultaneously introducing a core liquid into the inside hollow portion of the extruded spinning solution where the weighted densities of the spinning solution, quench liquid and the core liquid are regulated such that the average of the density of the core liquid and the spinning solution is about equal to the density of the quench liquid.

摘要： A dimensionally stabilized microporous polyamide membrane having enhanced flow characteristics comprised of a film forming organic polymeric material of low shrinkage prepared by drying the membrane, under conditions of restraint in the plane of the membrane to minimize the shrinkage until the membrane is essentially in a dried condition. A process is also described for preparing a microporous membrane designed to enhance incorporation and retention of a charge modifying resin for use as a charge modified filter media. The process comprises preparing a dope solution of a film forming polymer in a solvent system, directly casting the solution under the surface of a quenching medium comprising a non-solvent system for the polymer for a time sufficient to form micropores in the film, and drying the film while controlling the planar dimensions of the film during the drying.The foregoing process is particularly useful in the preparation of a charge modified membrane of enhanced electrokinetic capture potential in the filtration of charged submicronic contaminants from aqueous liquids.
