摘要： PROBLEM TO BE SOLVED: To provide adsorptive material with low pressure loss and the function of a highly adsorptive dust filter by adhering active carbon particles with partly exposed surface to cloth of three dimensionally structured textile. SOLUTION: On the surface or the face of the inner tissue in contact with the atmpsphere of ehis material composed of a sheet of coarse three dimensionally structured textile, with furrows on the surface if necessary, a binder layer composed of a polymer based adhesive not containing a latex, emulsion or solvent is formed, then active carbon particles are adhered to this binding layer and are being kept in a condition as to expose their part of surfaces to atmosphere, so, it is an adsorptive material which also has a function of filtering. Or further, it is the adsorptive material when coatings of binder layers are formed on the sheet's surface above mentioned. Further more, a manufacturing process of the adsorptive material to let the sheet pass through a fluid layer of active carbon porticles for the particles to be adhered to the binder layer is also included to. A ratio of openings between adsorptive preparation particles is being so high and the particles are spread uniformly, and moreover, the surfaces of the particles are so kept exposed that speed and volume of the adhering are high and large which make this material suitable for filters of air conditioners for automobiles.

摘要： PURPOSE:To improve appearance and gloss, etc., of active carbon and to increase its commercial value by coloring the active carbon without impairing its adsorptivity by adhering a colorant to the active carbon using an adhesive emulsion. CONSTITUTION:A colorant (e.g., cuporous iodide, cupric phosphate) is dispersed in water, and an adhesive emulsion (e.g., suspension of a mixture of acrylonitrile/butadiene latex with CMC) is admixed therewith simultaneously. Then, the suspension is added to granular active carbon, and dried after stirring the mixture sufficiently. Thus, colored active carbon is obtd. By this method, the active carbon is colored without reducing the adsorptivity of the active carbon. Blackening of hand is not caused even if the active carbon is touched by hand. The product has beautiful appearance and high commercial value when it is used as deodorizing agent, adsorbent, etc.

摘要： PURPOSE:To obtain an air purifying agent especially adsorbing lower aliphatic aldehyde gas, ammonia gas or the like by adding an aniline salt of an inorg. acid to a porous substance such as activated carbon. CONSTITUTION:As an air purifying agent especially effective for removing a tobacco smell in indoor air of an office or home, 1-30 pts. of an aniline salt of an inorg. acid or an inorg. acid and aniline is added to 100 pts. of a porous substance such as activated carbon. The air purifying agent thus obtained is excellent in the adsorbability of lower aliphatic aldehyde and ammonia gas and no desorption of aniline gas is generated at all. Further, even when the concn. of gas is varied, the re-discharge of gas once adsorbed is not generated. Therefore, this purifying agent is effective for the removal of a smell in usual living environment.

摘要： PROBLEM TO BE SOLVED: To provide a fluidized bonding method that makes absorbent particles bondable not only to the external surface of an air-permeable sheet but also to the surface of the internal tissue thereof at the same density without causing the decrease is adsorptivity of the particles, and to provide an apparatus therefor. SOLUTION: After an adhesive is adhered to the external surface and to the surface of the internal tissue of a sheet and then films formed in gaps of the tissue are removed by air blow, the sheet is passed through a fluidized bed 9 of absorbent particles and is pressed at a pressure roll 3. The sheet is then passed through a vibrator 4, where adsorbent particles insufficiently bonded fall off by vibration, and led to drying rolls 5 to dry the adhesive and to further cause adsorbent particles insufficiently bonded to fall off. Those particles separated from the sheet fall down to the fluidized bed and are reused. An adsorbent- contg. sheet obtd. by this method and apparatus is excellent in capability for removing traces of bad odor components in the air and is used for filters, etc., of air cleaners and air conditioners.
