    Abstract: PURPOSE:To provide a method for safely and easily producing a separation membrane module. CONSTITUTION:This fluid separation membrane module is a fluorine-base porous separation membrane module having such structure that at least a part of fine pores in the fluorine-base porous separation membrane is impregnated with a solidified potting material in the potting part of the module. This module is produced by treating the surface of the fluorine-base porous separation membrane with a surfactant and then bonding plural numbers of fluorine-base porous separation membranes with a potting agent having viscosity between in 100 to 1000 cp.

    Abstract: PURPOSE:To selectively collect a mutagenic substance present in air, by using a filter comprising a cation exchange fiber as a constitutional component. CONSTITUTION:The quantity of the cation exchange group in a filter is pref. 1meq/g on an average and the relation of the wt. Wg/m and the thickness Hmm of the filter is selected so as to satisfy the formula 0.0017 . When this structure is not satisfied, the number of contact times with the mutagenic substance becomes insufficient and the possibility of leakage is generated. In addition, if 1- 60wt% of moisture is contained in the cation exchange fiber, capacity can be increased.

    Abstract: PURPOSE:To obtain the titled filaments, having improved moire patterns, and capable of giving cloth having a dry touch, by spinning a polyamide containing a specific thermoplastic polymer, cold drawing the resultant filaments at a low draw ratio, and forming thick and thin boudary parts at a specific density randomly in the fibrous direction. CONSTITUTION:A polyamide, e.g. nylon 6 or 66, is mixed with 0.1-20wt%, preferably 0.2-15wt%, thermoplastic polymer, e.g. polystyrene or styrene-acrylonitrile copolymer, miscible with the polyamide, but incompatible therewith, and having the second order transition point >=80 deg.C, preferably >=100 deg.C, and the resultant mixture is then spun into filaments, which are then drawn at a draw ratio preferably 0.3-1.8 lower than that (3.8) to give an elongation of 45% without heating to afford the aimed filaments having average 10 or more/m thick and thin boundary parts (necking points) with sharp changing areas preferably within 0.5mm. randomly arranged in the fibrous direction.

    Abstract: PURPOSE:To exhibit an excellent effect in removal of malodorous gases and above all, night soil smells and the stimulating smells of cigarette smoke by disposing >=2 pieces of deodorizing units in series along the flow direction of air and disposing the adjacent deodorizing units via air space parts with each other. CONSTITUTION:Two or more pieces of the deodorizing units 2a, 2b are disposed by providing the space 3 between the adjacent deodorizing units. The number of the deodorizing unit is preferably >=2 pieces. The number of the space parts formed by the adjacent deodorizing units increases with an increase in the number and, therefore, the higher deodorizing effect is obtd. The sheet-like material which constitutes the deodorizing unit 1 is woven fabrics, non-woven fabrics, paper, felts, and net-like materials of natural and synthetic fibers. The deodorant is exemplified by wood alcohol oil extracted from plant, and chemical deodorants of a ferrous salt system, ferric phthalocyanine octacarboxylic acid system. The deodorant prepd. by compounding the oxycarboxylic acid compd. having >=2 carboxyl groups, a ferrous salt and sulfate or sulfite as the 3rd component is most preferable.
