摘要： PROBLEM TO BE SOLVED: To obtain a substrate which is a substrate for paper making, has woven flat yarns in the longitudinal direction and a controlled permeability, without using a bulky stuffed yarn and without causing troubles in strength or stability, is constituted wholly of a monofilament yarn and has low permeability. SOLUTION: This industrial substrate 20 for paper making has opposing ends provided with a system of flat monofilament (MD) yarns 22, 23, 24 and 25 in the longitudinal direction woven in a system of a yarn 21a in the processing crossing direction. The MD yarns are provided with the lower MD yarn 23 adjusted backward by a fixed distance from the end part of the substrate, a pair of the vertically adjusted upper MD yarns 22 and 24 and a pair of the lower MD yarns 23 and 25 and a series of perpendicularly intersecting ring-shaped parts are formed on each end part of a substrate from the upper MD yarn 22. The lower MD yarn 23 forms a ring shape at the rear and is directly woven right under the CMD yarn 21a in a space formed by the lower MD yarn 23.

摘要： PROBLEM TO BE SOLVED: To obtain an industrial fabric excellent in soil resistance and mechanical characteristics and suitable to a paper making or the like, by containing a fluoropolymer and an aromatic dicarboxylic acid polymer in a specific ratio. SOLUTION: This industrial fabric is produced by using yarns consisting of a mixture of a fluoropolymer such as an ethylenetetrafluoroethylene polymer with an aromatic dicarboxylic acid polymer such as a polyethylene terephthalate, in which the fluoropolymer contains >50% atomic weight of the fluorine atom in molecular weight of the polymer, the aromatic dicarboxylic acid polymer contains one or more aromatic discarboxylic acids as recurring units in the polymer, and portions of two continuous aromatic dicarboxyl groups are sometimes separated by a linker part such as a 1-6C alkyl or the like. The fluoropolymer and the aromatic dicarboxylic acid polymer in total occupy approximately 100% of the yarns, and a ratio of the fluoropolymer to the aromatic dicarboxylic acid polymer is (70/30)-(99/1).

摘要： A woven or spiral papermaker's or industrial fabric characterized in that at least a portion of its fibers have two or more thin fins, some of which fins are designed for ease of flexing or compression by incorporation of a reduced cross section "hinge" area or by a variation in thickness of more than 20 per cent as a function of distance from the fiber center. This will achieve interlocking between crossing fibers at significantly reduced "beat-up" force in weaving or less shrinkage force in spiral fabrics. By remaining extended where there is no fiber to fiber crushing action, the fins fill the fabric interstitial spaces and control fabric porosity. Significant cost and quality benefits are achieved.
摘要翻译：纺织或螺旋造纸机或工业织物，其特征在于，其纤维的至少一部分具有两个或更多个薄翅片，其中一些翅片设计成易于通过结合减小的横截面“铰链”面积或通过与纤维中心距离的函数的厚度的变化大于20％。这将实现交叉纤维之间的互锁，在织造中显着减少“踩踏”力或螺旋织物中较小的收缩力。通过在没有纤维到纤维破碎作用的地方延伸，翅片填充织物间隙空间并控制织物孔隙率。实现了巨大的成本和质量收益。
