Abstract: The present invention provides an apparatus for manufacturing activated carbon fiber, which enables continuous production with high productivity. This apparatus is configured in a U-shape and comprises the first vertical furnace, the second vertical furnace, and the connecting portion to connect both furnaces at the lower parts. This apparatus employs neither the air curtain method nor the water seal method that requires drying process to shut off air from the furnace. In this apparatus, raw materials are introduced from the inlet on the upper part of the first furnace. Then they are subjected to pyrolysis, carbonization, and activation as they pass through the first furnace, connecting portion and the second vertical furnace. Finally they are taken up from the outlet on the upper part of the second furnace to be an active carbon fiber product.

Abstract: A process for producing an artificial leather having excellent touch, appearance and full-hand similar to that of natural leather and having further excellent softness and surface strength, which comprises coating a composition comprising an urethane prepolymer, a combination of catalysts and a foam stabilizer and including a plurality of extremely fine cells (foams) of an inert gas, onto a release paper or a layer of a surface treating agent coated on a release paper in a specified thickness; subjecting the resultant to a steam treatment under a specified atmosphere; laminating a base sheet onto the coating layer under pressure; subjecting the laminated product to a heat treatment at a specified temperature, and then peeling off the release paper, and optionally further treating the product with a surface treating agent.

Abstract: A process for the production of artificial leathers having excellent air permeability and resembling a natural leather is provided, which comprises incorporating a catalyst, a foam stabilizer and, optionally, a pigment and other additive into an isocyanate-terminated polyurethane prepolymer formed by compounding a polyester diol derived from an aliphatic dicarboxylic acid with an organic polyisocyanate so that the [NCO]/[OH] ratio is within a range of from 2.0 to 4.0, to thereby form a substantially solvent-free paint having a viscosity adjusted to 70 to 1000 poises, coating the paint on a release paper in an amount of 50 to 400 g/m.sup.2, applying the release paper to a substrate, allowing foaming and polymerization reactions to proceed in an atmosphere of a dry-bulb temperature of 40.degree. to 95.degree.C.
