Abstract
(EN)
It is intended to provide a polyester fiber for reinforcing high heat resistant rubber capable of retaining the shape even at a high temperature, particularly at a temperature not lower than the melting point of polyester without lowering the productivity. A polyester composite fiber having a core/sheath structure in which a crosslinked structure is formed in at least part of the fiber by obtaining a core/sheath composite polyester fiber using polyester obtained by reacting a compound having an unsaturated bond at a polyester molecular chain end and subjecting the obtained composite polyester fiber to ionizing radiation. A tire cord using the polyester fiber, and a radial tire using the tire cord as a carcass material.

La présente invention concerne une fibre polyester destinée à renforcer un caoutchouc résistant à de hautes températures qui peut conserver sa forme même à haute température, en particulier à une température non inférieure au point de fusion du polyester, sans baisse de productivité. Une structure réticulée est formée au moins dans une partie d'une fibre polyester composite à structure âme/gaine par obtention d'une telle fibre polyester composite au moyen de polyester produit par réaction d'un composé ayant une liaison insaturée au niveau d'une fin de chaîne moléculaire de polyester, la fibre polyester composite obtenue subissant ensuite un rayonnement ionisant. La présente invention concerne également un câblé employant la fibre polyester et un pneumatique radial utilisant le câblé comme matériau de carcasse.
