    • 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) of 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 ply of ply twist yarn made from combination of said ply twist yarn or impart cable twist 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.
    • 本发明的目的是提供一种由人造丝和莱奥塞纱组成的混合浸渍帘线,以应用于使用其的汽车和子午线轮胎中使用的充气子午线轮胎的胎体帘布层或帘布层(带束层加强层) 。 此外,根据本发明,通过以下步骤制造用于汽车中使用的充气子午线轮胎的胎体帘布层或帘布层(带束层加强层)的混合浸渍帘线和子午线轮胎。 对一根人造丝进行20〜200TPM纱线的S方向扭转以产生预纱线,分别对所述一个人造丝预纱线和一个非扭曲的lyocell进行扭曲以产生层叠捻纱,并且将电缆捻向 由所述帘布层加捻纱线组合制成的双层捻线,或通过将一根莱奥纱线和人造丝纱线的人造丝纱线调节到20〜200TPM的捻纱数为20〜200TPM而制成的帘布层捻线, 层捻过程。
