Abstract: PURPOSE:To obtain a sealing material capable of filling a surface gap even under low compressive force and exhibiting high sealbility, by forming a dried coating film composed of a mixture of fine powder of tetrafluoroethylene resin and a fluororubber solution to a surface of a sintered tetrafluoroethylene resin. CONSTITUTION:The objective sealing material is produced by coating a surface of a sintered tetrafluoroethylene resin with a mixture of (A) tetrafluoroethylene resin powder having primary particle diameter of about

Abstract: PURPOSE:To easily produce a hollow yarn module having high productivity and uniform distribution density of hollow yarn by adding a stage for bonding both end parts of the hollow yarn to each other by spraying an adhesive agent to the hollow yarn in the neighbourhood of an edge of a rotary drum having the hollow yarn wound therearound, etc., to a process for producing a hollow yarn module. CONSTITUTION:A stage for aligning hollow yarn 1 wound around a square cylindrical rotary drum 4 supported freely rotably on a shaft, and a stage for bonding the hollow yarn to each other by spraying a semifluid adhesive agent 8 to the aligned hollow yarn 1 in the neighbourhood of an edge 5 of the rotary drum 4, or by laminating an adhesive agent which has been semisolidified to form a sheet, are repeated alternately, and the hollow yarn 1 is cut at the neighbourhood of the edge of the rotary drum 4 to form a bundle of the hollow yarn 1. The bundled hollow yarn obtnd. in the above described processing stage is inserted into a separately prepd. case, and bonded parts at both ends are bonded to the internal wall surface of the case. Thus, a complete hollow yarn module is obtd.
