Abstract: A three-dimensional non-woven fabric having at least one junction portion in the internal portion thereof may be obtained by forming, and maintaining a distance between, linear junction portions in a piece of starting non-woven fabric or in a laminate of a plurality of layers of starting non-woven fabric, followed by cutting the formed non-woven fabric at a position or along a line between one linear junction portion and another linear junction portion; or by forming dot-like junction portions in a piece of a starting non-woven fabric or in a laminate of a plurality of layers of a starting non-woven fabric, followed by cutting the formed non-woven fabric into a desired shape so as to include the dot-like junction portion. The three-dimensional non-woven fabric has a large strength, excellent shape stability, large surface area, thereby being advantageously utilizable as a carrier for fixing or immobilizing microorganisms or in various other applications.

Abstract: The present invention relates to absorption resins comprising vinyl copolymers which do not dissolve in water and are capable of adsorbing microorganisms without inactivating the microorganisms and also adsorbents with a large contact area which are capable of adsorbing microorganisms efficiently as well as methods of making the resins and the adsorbents.

Abstract: A microporous, polymeric film is prepared by dissolving methylene-chloride-soluble, film-forming polymers completely in methylene chloride. Then an aqueous phase is prepared containing non-methylene-chloride-soluble, water-soluble thickeners and, if desired, additives, and brought to a viscosity of about 0.07 to 0.5 Pa s. The aqueous phase is then dispersed in the polymer solution and the resultant paste is spread onto a support material or intermediate support, the methylene chloride is evaporated, the resultant membrane is transferred to the actual support, and finally the water is removed by drying.

Abstract: A material with high thermal conductivity for insulating electronic parts is formed by exposure to a compressive shearing force of a compound containing 50 to 95% by volume heat conductive, inorganic powder and 5 to 50% by volume bonding agent. The bonding agent contains at least 0.2 to 30% by volume polytetrafluoroethylene (PTFE), preferably 1.0 to 20%, and synthetic rubber, where the volume ratio of rubber is 1/4 or more of the PTFE. The compressive shearing force fibrillates the PTFE and disperses the inorganic powder so that there is an even aggregation of heat conductive material. Other ingredients such as vulcanizing agents, vulcanizing accelerators, stabilizers, processing aids, flame retardents, coloring agents, and solvents may be added. The material may be reinforced with a woven or non-woven fabric or staple fibers.
