Abstract: PURPOSE:To obtain flocked cloth excellent in soft touch and having a pile part hardly falling down by external pressure, by constituting the pile part of fine long fibers and thick short fibers. CONSTITUTION:Fine long fibers 2 and thick short fibers 3 are flocked on a base material 4 to form a pile part. The monofilament fineness of the fine long fibers 2 is 5 denier (d) or less and the fiber length (L1) thereof is 5mm or less, pref. 1-2mm while the monofilament fineness of the thick short fibers 3 is 6d or more and the fiber length (L2) thereof is L2

Abstract: PURPOSE:To obtain the title medium suitable for raising seedling and culture of all plants such as vegetables or flowers, capable or readily controlling water absorption properties and water permeability by blending synthetic short fibers with thermally bondable fibers, opening, forming and heat-treating. CONSTITUTION:Synthetic short fibers having =30 deg.C lower melting point than the synthetic short fibers), opened by an opening machine and formed by a forming device into a desired shape and dimension. Then the formed material is heat-treated at >=120 deg.C to give the objective medium.

Abstract: PURPOSE:To obtain the titled fiber of low coefficient of friction, outstanding in adhesivity and gas-liquid separation characteristics, by melt spinning, through a modified cross-section spinneret, with the spinning speed controlled to specified value, of a specific fluoroethylene polymer followed by annealing at specified temperature and then cooling. CONSTITUTION:The objective fiber can be obtained by melt spinning, through a modified cross-section spinneret, with the spinning speed controlled to 5-20m/min, of at least one kind of polymer selected from olefin/ tetrafluoroethylene copolymers, hexafluoropropylene/tetrafluoroethylene copoly mers perfluoroalkylvinyl ether/tetrafluoroethylene copolymers, hexafluoropropy lene/perfluoroalkylvinyl ether/tetrafluoroethylene copolymers, olefin/ chlorotrifluoroethylene copolymers and polychlorotrifluoroethylene followed by annealing the delivered liquid at temperatures between the melt temperature and the melt temperature minus 50 deg.C and then cooling to

Abstract: PURPOSE:To reduce pressure drop by arranging a filter member consisting of polytetrafluoroethylene-base modified cross-section fiber to the midway part of a cylindrical vessel and providing both a supplying port of gas to be treated and a discharging port of separated liquid to the lower side thereof. CONSTITUTION:The gas to be treated is supplied into a cylindrical vessel 1 through the supplying port 2 and passed through a filter member 5. In this case, mist is allowed to collide against the surface of polytetrafluoroethylene- base modified cross-section fiber 6, collected and falls as droplets and is discharged through a discharging port 3. On the other hand, only the gas is exhausted through an exhausting port 4. In case of utilizing such fiber stock as the filter member, pressure drop is reduced because it has large porosity and mist collecting efficiency is improved.
