<p>PURPOSE:To give strong and rapid adsorbability by burying one part of a very slender carbon fiber into the plastic material surrouding continuous foams and by exposing the rest of the activated carbon fiber in said foams. CONSTITUTION:An infinite number of continuous foams 2 communicating each other are partitioned by a hardened foam urethane membraneous substance 1 and an infinite number of very slender activated carbon fibers 3 (about 7-15mu in diameter, about 0.3-2.5mm in length) are protruded and exosed in these foams 2. One part of the length is kept by the urethane membranenous substance whose thickness is 1/several-1/10mm or less and said substance does not fall of easily. The micropores of the fiber surface are not colsed or disturbed by other substances, so the part protruded into the foams 2 of the activated carbon fiber 3 are directly contacted with the gas or liquid flowing in the continuous foams 2, thus offensive smelling ingredients in the gas or harmful ingredients can be adsorbed and removed rapidly and strongly.</p> |
