    Abstract: A steel cord is formed by compactly twisting steel filaments together, the steel filaments including a plurality of zigzag filaments and optionally a nonzigzag filament, the zigzag filament being zigzaged two-dimensionally and made up of straight segments each extending between the zigzag peak points, the nonzigzag filament being straight. In case the cord is composed of only the zigzag filaments, the zigzag filaments include at least two kinds of zigzag filaments having different zigzag pitch lengths. In case the cord is composed of both the zigzag filaments and nonzigzag filaments, some of the zigzag and nonzigzag filaments are first loosely twisted together into a bunch, and then a plurality of bunches are twisted together into the cord. In any case, the zigzag pitch length and zigzag wave height of each zigzag filament are substantially constant along the length thereof. A Tire comprises a reinforcing layer such as a tread reinforcing belt layer, carcass, bead reinforcing layer and the like made of the above-mentioned steel cords.

    Abstract: A high-strength, low weight, electromechanical cable is manufactured from aromatic polyamide multifilament yarns impregnated with a hydrolytically stable polyurethane resin to form a protective coating. The coating provides load adjustment from fiber to fiber, eliminates abrasive self-destruction of the fibers during flexing of the yarn under load, protects the fiber to some extent from ultraviolet radiation, aggressive chemicals or abrasive particles and makes it possible to preform the yarn. The coating comprises a reaction product of a liquid tetramethylene glycol, an aliphatic/cycloaliphatic diisocyanate and a diamine coupling-curing agent. The impregnated yarns are dried, twisted together, heated above the softening point of the resin to fuse the coatings of adjacent yarns, and then cooled to form a set twisted helix of the yarns.

    Abstract translation: 高强度，低重量的机电电缆由浸渍有水解稳定的聚氨酯树脂的芳族聚酰胺复丝纱线制成以形成保护涂层。 涂层提供从纤维到纤维的负载调节，消除了纱线在负载弯曲过程中纤维的磨损自毁，在一定程度上保护纤维免受紫外线辐射，侵蚀性化学物质或磨料颗粒的影响，并使纱线预成型成为可能。 涂层包括液体四亚甲基二醇，脂族/脂环族二异氰酸酯和二胺偶联固化剂的反应产物。 将浸渍的纱线干燥，扭曲在一起，加热到树脂的软化点以使相邻纱线的涂层熔合，然后冷却以形成纱线的扭曲螺旋。
