The invention relates to the field of tire rubber materials, in particular to a nylon cord thread and a tire prepared from the same. The cord thread at least comprises two strands of nylon 6 silk threads, each strand of nylon 6 silk threads is subjected to Z-direction first twisting to form plied yarns, and all the plied yarns are stranded and subjected to S-direction second twisting opposite to the first twisting direction to form the nylon cord thread. The specification of the nylon cord thread is any one of 840D/2, 1260D/2 and 1890D/2; the first twist number of the nylon 6 silk yarn is 5%-50% lower than that of the traditional nylon 6 silk yarn with the same specification; the twisting angle of the nylon 6 silk yarn is 1-6 degrees lower than that of the traditional nylon 6 silk yarn with the same specification; the second twisting number of the nylon 6 plied yarn is 5%-50% lower than that of the traditional nylon 6 plied yarn with the same specification; the second twisting angle of the nylon 6 plied yarn is 2-12 degrees lower than that of the traditional nylon 6 plied yarn with the same specification; and the density of the nylon 6 silk yarns is 7D-12D. The tire prepared from the nylon cord provided by the invention breaks through the limitation that the nylon 6 cord is poorer in performance and size stability than the application in the tire, and the purpose of reducing the cost can be achieved on the premise of maintaining the performance of the tire.

    本发明涉及轮胎橡胶材料领域,特别涉及一种尼龙帘线及其制备的轮胎。帘线至少包括两股尼龙6丝线,每股尼龙6丝线先各自进行Z向初捻形成股线,每个股线合股进行与初捻方向相反的S向复捻形成尼龙帘线;尼龙帘线的规格为840D/2、1260D/2、1890D/2中的任意一种;尼龙6丝线的初捻捻数较同规格传统尼龙6丝线低5%‑50%;尼龙6丝线的捻角较同规格传统尼龙6丝线低1°~6°;尼龙6股线的复捻捻数较同规格传统尼龙6股线低5%‑50%;尼龙6股线的复捻捻角较同规格传统尼龙6股线低2°~12°;尼龙6丝线的密度为7D~12D。采用本发明提供的尼龙帘线制备的轮胎打破了尼龙6帘线因性能及尺寸稳定性较差于轮胎中应用的限制,可在维持轮胎性能的前提下,达到降低成本的目的。
