摘要： PURPOSE:To manufacture a fluorine resin flexible laminate of superior flexing resistance, particularly in the cold season, elasticity, resistance to weather, resistance to oils and antifouling by forming a thick polyurethane resin layer or layers on a surface or the surface and rear surface of a base cloth of a special structure fabric constituted of warp layers consisting of a number of warps in parallel, weft layers consisting of a number of wefts in parallel crossing warps and interlocking yarns interlocking and connecting crossings and forming a thick fluorine resin film layer on the upper surface of a surface layer. CONSTITUTION:A laminate includes a special structure fabric base cloth, a polyurethane intermediate layer formed on one surface of the base cloth and a fluorine resin surface layer formed on said intermediate layer. The base cloth is constituted of natural fibers such as cotton and linene and synthetic fibers such as nylon 6 and others, and the fibers are arranged respectively in parallel, and laminated in a manner that warp layers and waft layers formed with the fibers are crossed with each other and connected loose at the crossings of warps and wefts by means of long interlocking yarns. The interlocking yarns are selected out of synthetic fibers such as polyester and nylon and inorganic fibers such as glass fibers and steel fibers. The generation of cracks in the cold season for the laminate thus prepared is less than for a laminate using plain weave fabric as base cloth this arrangement.

摘要： PURPOSE: To realize a surface which is highly soft and easy to work for a roller for record cleaning, by foming the surface with the elastic resin composed mainly of polynorbornane and containing the viscid resin.
CONSTITUTION: The polynobornane is obtained by synthesizing the norbornane with ethylene and cyclopentadiene through the Diels-Alder reaction and then giving the ring oprning polymerization to the norbornane. This polynorbornane is plasticized with addition of the aromatic oil or naphthenic oil to show the elasticity like rubber. Then the viscid resin is added to the elastic polynorbornane in a range of 10W50wt%. Such elastic resin is used on the surface 6 of a rotary roller 2. Thus the dust on a record disc can be cleared away easily.

摘要： PURPOSE:To obtain the title sheet capable of readily handling and firmly thermally sewing by fixing a crude mesh fabric-like base cloth of warp and weft of multifilament yarn through a specific covering layer of yarn in a crossing point of yarn. CONSTITUTION:Warp 1 and weft 2 of a multifilament yarn are each covered with a foam layer of a thermoplastic polymer to afford covered yarns 1A and 2A. Melting point of the thermoplastic polymer of covering layer 1a is at least 5 deg.C lower than the melting point or thermal decomposing temperature of the multifilament yarn of warp 1 and weft 2. The covering layer 1a is pressed together with the yarn and crossing point of the yarn is wrapped with the covering layer to mutually fix the yarn. Cross section of the yarn is formed into flat shape (11:12=1.3:1 to 5:1) parallel to the plane of sheet by pressure. Weft 2A of the base cloth extends in arc state mutually in parallel.

CONSTITUTION:A special structure coarse mesh woven stuff is prepared by using 11 polyester filaments of 1000 denier for warp yarn 2 and cotton yarn 4, respectively, and a nylon filament thread of 110 denier for binding yarn 5. The woven stuff is immersed and impregnated into insulation processing liquid, whose pick-up rate is then made 100%, dried, and gelling heating at 180 deg.C is applied thereto to seal a resin. Thereby, an insulating coarse mesh sheet 1 is formed. Then, a transparent flexible conductive sheet 2 is formed which contains polyvinyl chloride resin of 100 pts.wt. and tin oxide powder of 10 pts.wt. and has a thickness of 0.1mm and a resistivity of 104 to 106OMEGA.cm. The transparent conductive sheet 2 is heated and bonded to both sides of the insulating coarse mesh sheet 1 by using a calender to form a flexible sheet.

摘要： PURPOSE:To produce an excellent anti-bending property, particularly, the anti- bending property in cold period by forming a layer having a sufficient thickness of flexible polyvinyl chloride resin on the surface or the front and rear surface of a special structure fabric base cloth, and forming a thin acrylic film layer at least on the surface layer. CONSTITUTION:A fabric comprises the warp 1 and weft 2, and the leno yarn 3. Flexible PVC resin layers 5, 5' are formed on both surfaces of a base cloth 4, however, an acrylic layer 6 is provided at least on the upper surface of the PVC resin layer 5 which comes out on the surface thereof. It may be possible to omit the PVC resin layer 5' on the rear surface, or to provide the acrylic film 6 also on the PVC resin layer 5'. The laminate obtained through this fashion may have loss crack generation in cold period as compared with a conventional fabric, for example, a laminate made of a base cloth as a plain woven fabric.
