摘要： An apparatus for the preparation of an elastic absorbent composed of a mixed web. Elements of the apparatus can include two supply hoppers for separately supplying pulverized pulp and staple fibers of a synthetic fiber split yarn at a constant mixing ratio with each hopper having a pair of confronting moving belts, two guide mechanisms located below the hoppers, a pair of nip rollers located below the guide mechanisms, a garnet roll located below the pair of nip rollers, a vacuum device located below the garnet roll, and a mesh belt located between the vacuum device and the garnet roll. Each guide mechanism in the apparatus may include at least two gear guides arranged in series. The apparatus operates by feeding the pulverized pulp and the staple fibers of the split yarn from the hoppers to the nip rolls via the guide mechanisms. The nip rolls compress the material, which is then disintegrated and mixed by the garnet roll. The mixture is pulled onto the mesh belt by the vacuum device.

摘要： An apparatus for producing multifilaments having high fiber strength is disclosed. A spinneret melt spins a polyolefin at a first temperature into filaments. A cooling duct cools the filaments via convection at a second temperature. A chill roll, disposed downstream from the cooling duct, has a third temperature, and forcibly conductively cools the filaments. Finally, heated drawing rolls, disposed downstream from said chill roll, continuously draw the filaments at a high draw ratio.

摘要： A method for producing composite staple fibers whereby resin matrix and fine and short inorganic reinforcing fibers (e.g., vapor growth carbon fibers and/or potassium titanate whiskers) are processed. A resin material and fine and short inorganic reinforcing fibers having a fiber diameter of 1 .mu.m or less are blended, heated, and mixed to prepare a molten polymer containing dispersed reinforcing fibers. The molten polymer is spouted out of small apertures in a high speed rotator to form filaments. Hot gas is blown onto the spouted filaments to form composite staple fibers. Instead of using the spouting step and the hot gas blowing step, one can spin the molten polymer from spinning apertures into filaments, and simultaneously blow hot gas onto the filaments at a high flow velocity from gas discharging holes arranged near the spinning apertures to draw and cut the filaments into the staple fibers.
