"POLYESTER CORDS AND USE OF THEM IN EMPTY TIRES". The present invention relates to an empty wheel tire having at least one of its components comprising the radial casing ply, the bottom layer, the top layer, bead inserts or bead reinforcements in the bead area. with polyester cords that have a polyepoxide arranged on their surface. The polyester cord is first formed by obtaining a cord by braiding each other of a plurality of polyester yarns, secondly by treating the cord with an aqueous dispersion comprising a polyepoxide, and thirdly by treating the cord. with an aqueous RFL dispersion comprising a resorcinol formaldehyde resin, a styrene butadiene copolymer latex, a vinylpyridine styrene-butadiene terpolymer latex, and a blocked isocyanate. |
