    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 method for manufacturing improved synthetic bonded filament yarn by forming a unit composite from matrix and island components, assembling a plurality of the unit composites into a randomly bundled multifilament yarn and heating the multifilament yarn at a temperature between the melting points of both components. The cross section of the unit composite can be obtained in any of so-called sheath-core configuration, randomly distributed configuration and bimetallike configuration of the components. The bonded filament yarn has excellent flexibility and a unique surface condition having many wrinkles thereon and the bonded filament yarn of the present invention can be advantageously used for numerous industrial uses such as chafer fabrics of tires, bowstrings, fishing nets, guts of rackets, etc.

    Abstract translation: 通过从基体和岛部件形成单元复合材料制造改进的合成接合长丝纱线的方法，将多个单元复合材料组装成随机卷绕的复丝纱线，并在两个部件的熔点之间的温度下加热复丝纱线。 所述单元复合材料的横截面可以以任何所谓的皮芯构型，组件的随机分布构型和双金属配置来获得。 粘合长丝纱线具有优异的柔软性和独特的表面状况，其上具有许多皱纹，本发明的粘合长丝纱线可有利地用于许多工业用途，例如轮胎胎圈包布织物，弓弦织物，渔网，球拍外套等 。

    Abstract: 1300268 Pile fabrics; yarns TORAY INDUSTRIES INC 4 June 1970 26927/70 Headings D1K and D1W A pile fabric with pile yarns of very fine fibres 2 is made by encasing at least five of the fibres in a composition different to that of the fibre material to form a composite fibre and removing the encasing material after the fibres have been made into the fabric. The composite fibres may be severed into staple fibres and spun into a yarn. The yarn may be incorporated as the pile yarn in a warp or weft pile fabric, woven into a fabric which is subsequently napped, used as the pile in an electrostatic flocking process or made into a non-woven needle-piled felt. The non-woven felt may be a laminate of two different pile materials with the pile of each surface having different characteristics. Various materials of natural and synthetic origin for the fibre and encapsulation substances are described and a formula is given for the length to thickness ratio and bending torque of the composite fibre.
