摘要:
A process for the preparation of unopened sheet-formed and reticulated fibrous structures, which comprises:A. extruding a molten thermoplastic resin containing a foaming substance through a die with a slit clearance of 0.1 - 1.0mm;B. quenching the extrudate at a point less than 5mm away from the die surface to a temperature below the glass transition temperature of the resin; andC. simultaneously drafting the extrudate at a draft ratio between the maximum draft ratio possible under the conditions and one-third thereof, thereby fibrillating the extrudate just as it leaves the die exit.
摘要:
A composite structure is prepared by extruding a molten thermoplastic resin and foaming agent through a die and simultaneously quenching and taking-up the extrudate under such conditions that the extrudate is fibrillated just as it leaves the die exit without passing through the foamed state. The unopened, sheet-formed and reticulated fibrous structures thus obtained are laminated, pulled apart and pressed. The composite product consists of a fine and uniform fibrillar structure having superior mechanical strength and pliability and are useful for a wide range of applications such as paper substitute, artificial wood veneer and the like. Colored products are also described.
摘要:
An oil or organic solvent-absorbent is prepared by extruding a molten thermoplastic resinous polymer blend of polystyrene and polyethylene containing a foaming agent through a die having a slit aperture of 0.1 - 1.0 mm width, quenching the extrudate at the die exit to a temperature below the glass transition point of the resinous blend, drafting the extrudate at a draft ratio from the maximum draft ratio possible under the operating conditions to one-third the maximum draft ratio, laminating at least two sheets of the resulting unopened, sheet-like reticulated structure having numerous non-continuous cracks along one direction so that the direction of the cracks of each such sheet is the same, pulling the laminate in a direction perpendicular to the direction of the cracks to separate the constituent fibers from each other, and crimping the opened, sheet-like laminate either alone or together with at least one other sheet-like material; a process for removing oil or organic solvents with the absorbent product.

A sheet feeding device includes a sheet supporting portion, a sheet feeding portion, and a movable regulating portion. The sheet feeding portion feeds a sheet bundle uppermost sheet. The movable regulating portion is disposed downstream of the sheet bundle in a sheet feeding direction such that the movable regulating portion is tiltable between a regulation position and a regulation release position. While the movable regulating portion regulates the sheet bundle movement in the regulation position, the sheet feeding portion forms a loop in the uppermost sheet between the sheet feeding portion and the movable regulating portion, the movable regulating portion is moved to the regulation release position after loop formation to remove the formed loop, and the movable regulating portion is returned to the regulation position after loop removal such that the movable regulating portion raises the uppermost sheet leading end to separate the uppermost sheet from other sheets.

摘要:
A solvent-resistant filamentary structure having superior ion-exchangeability which comprises at least 20% by weight of aromatic nuclear structural units derived from an aromatic monovinyl monomer, 2 to 40 out of 100 of said aromatic nuclear structural units being cross-linked by crosslinkages of the formula ##EQU1## said filamentary structure not containing a crosslinkage expressed by the formula ##EQU2## and the remainder of said aromatic nuclear structural units, either partly or wholly, having incorporated therein an ion-exchangeable group, and a method for producing the same.

A plurality of output destinations such as a mail server and a printer are connected via a network, and image formats or resolutions are set as image scanning parameters for each output destination. A parameter that is common to each of the output destinations is selected from the set parameters, an image is read in accordance with the parameter selected and the read image data is output to each of the output destinations via the network.
