  • organic fibers When organic fibers are used for the S material, it is difficult to completely fill the entire lumen because the melting points of many materials are 180 t: or more. Therefore, it is preferable to coat the surface of the organic fiber with rubber, rubber paste or plastic having high fluidity under heating.
  • organic fibers are generally hygroscopic, and this moisture diffuses into the steel cord, causing the steel cord to ripen. Therefore, it is desirable that the moisture content (JISL-107) of the organic fiber cord be 0.2% or less.

Abstract

L'espace à l'intérieur d'un câble d'acier (10, 17) formé en entrelaçant étroitement une pluralité de brins d'acier est rempli d'un matériau non métallique (16, 25), tel que du caoutchouc, du plastique ou des fibres organiques, pour empêcher l'inclusion d'air dans le câble d'acier lorsque ce dernier est noyé dans du caoutchouc et est soudé à celui-ci par vulcanisation, empêchant ainsi toute corrosion, tout en maintenant la stabilité dimensionnelle du câble.
