    Abstract: A COMPOSITE SHEET SUBSTANCE HAVING THE SIMILAR APPEARANCE AND PHYSICAL PROPERTIES TO THE GENUINE LEATHER IS MANUFACTURED BY MEANS OF USNG FIBROUS MATERIAL COMPOSED OF A PLURALITY OF FINE FIBERS OR FLAMENT AND AN ELASTIC POLYMER SURROUNDING THE FINE FIBERS. A BONDED FIBROUS MATERIAL COMPOSED OF FIBROUS COMPONENT (A COMPONENT) CONTAINING A PLURALITY OF FINE FIBERS OF FILAMENTS AND ANOTHER COMPONENT OF BONDING AGENT (B COMPONENT) BOUND THE ABOVE-MENTIONED FINE FIBERS OR FILAMENTS IN A BUNDLE. FUTHER A SHEET COMPOSED OF THE BONDED FIBROUS MATERIAL IS MADE. THE A COMPONENT HAS DIFFERENT DISSOLVING PROPERTY BY SOLVENT FROM THE B COMPONENT. NEXT THE ABOVE-MENTIONED SHEET IS INVOLVED WITH A POLYMER (C COMPONENT) HAVING A DIFFERENT SOLVENT DISSOLVING PROPERTY FROM THE A AND B COMPONENTS. THE B COMPONENT IS TAKEN OUT FROM THE PRODUCT OF THE INVOLVING TREATMENT BY MEANS OF DISSOLVING INTO A SOLVENT HAVING PARTICULAR ABILITY FOR DISSOLVING THE B COMPONENT ONLY. NEXT A SUBSTANCE MAINLY COMPOSED OF AN ELASTIC POLYMER (D COMPONENT) IS IMPREGNATED INTO THE SHEET AFTER TAKING OUT THE B COMPONETNT, FUTHER THE C COMPONENT IS TAKEN OUT FROM THE SHEET BY MEANS OF DISSOLVING INTO A SOLVENT HAVING PARTICULAR ABILITY FOR ONLY DISSOLVING THE C COMPONENT AFTER THE ABOVEMENTIONED IMPREGNATING TREATMENT, AND FINALLY THE COMPOSITE SHEET SUBSTANCE OF THE PURPOSE IS PRODUCED. IN THE ABOVEMENTIONED MANUFACTURING STEPS, THE SIMILAR RESULTS CAN BE OBTAINED BY APPLYING THE DIFFERENT COMBINATION OF THE STEPS TO THE GENUINE LEATHER, IN OTHER WORDS THE OPERATIING ORDER OF THE TAKING OUT OPERATION OF THE B COMPONENT AND THE IMPREGNATION OPERATION OF THE ELASTIC POLYMER (D COMPONENT) CAN BE CHANGED.

    Abstract: A synthetic filament and a yarn composed thereof wherein the filament comprises at least two different incompatible synthetic linear high polymers, one being distributed as islands in the sea of the other polymer element when seen in cross-section, each island being continuous along the axis of the filament and being characterized by their uniformity in cross-sectional dimension in any cross-section of the filament.

    Abstract: A needle, needle punching machine and process are provided for producing a needle felted fabric that is useful for producing artificial leather. In the needled fabric some of the fibers are displaced by needles and caused to penetrate through others of the fibers; at least 60 percent of the fibers which penetrate do so either individually or as a group of 2 or 3 fibers.

    Abstract: A spinning apparatus valuable for obtaining uniform ''''islandsin-a-sea'''' type composite filaments comprises a uniting chamber comprising a funnel-shaped space having a converging angle of at most 75*. The apparatus may further include means for supplying the sea constituent polymeric liquid into a central portion and an outside portion of the uniting chamber, and means for incorporating the island constituent polymeric liquid with the sea constituent polymeric liquid in an eccentric manner. These means are effective for maintaining the ''''islands-in-asea'''' type composite stream in the uniting chamber at a favorable equilibrated condition for a long spinning period.
