A DIPPED CORD USING HYBRID CORD AND A RADIAL TIRE USING THE SAME

摘要

It is an object of the present invention to provide a hybrid dip cord consisting of rayon yarn and lyocell yarn to apply to the carcass ply or cap ply (belt reinforced layer) of pneumatic radial tire used in a car and a radial tire using the same. And also, according to the present invent the hybrid dip cord and the radial tire for application to the carcass ply or cap ply (belt reinforced layer) o f pneumatic radial tire used in cars are produced by means of the following steps; imparting S direction twist of 20 to 200 TPM yarn number to one rayon yarn to produce a pre-yarn, imparting twist to said one rayon pre-yarn and one non-twisted lyocell respectively to produce a ply twist yarn, and imparting cable twist to two p ly of ply twist yarn made from combination of said ply twist yarn or impart cable twis t to a ply twist yarn to be produced by regulating low the twist number of one lyocell yarn and the rayon yarn to one lyocell as 20 to 200 TPM when the ply twist processes.
