发明名称 Multitubular sheaths with reinforced structure for lead-acid battery electrodes.
摘要 <p>Multitubular sheaths with a reinforced structure for lead-acid battery electrodes, particularly suitable for filling with lead oxides blend in liquid, slurry or creamy paste form, having porosity characteristics which permit the outflow of liquid, keeping the oxides on the inside. The fabric with which said sheaths are produced is formed, in warp, by continuous elastic high-tenacity polyester yarns, twisted and thermoretractable; in weft, alternately by an elastic multifilament yarn of high tenacity, thermostabilized, and with a twist of at least 200 turns per metre, and a high tenacity multifilament yarn textured or voluminized and/or twisted and stapled. The combination of continuous elastic high tenacity multifilament yarns, highly twisted, and high tenacity voluminized stapled yarns produces a fabric characterized by high mechanical resistance,by very good resistance to oxidation, by longitudinal and trasversal elasticity and by high porosity, this latter created not only by mesh openings (macroporosity) but also inside the voluminized and stapled yarn itself (microporosity).</p>
