Abstract: The present application relates to a hybrid cord including a bio-based nylon primarily twisted yarn. According to the present application, while including a primarily twisted yarn including bio-based nylon having a higher modulus compared to chemical-based nylon, there is provided a hybrid cord and has elongation and fatigue resistance equivalent to or higher than commercially required levels (i.e., the level that the cord including a conventional chemical-based nylon primarily twisted yarn has).

Abstract: According to the present disclosure, there is disclosed a hybrid tire cord capable of realizing high performance and weight reduction of a tire by having strong adhesion to rubber and excellent fatigue resistance as well as high tenacity and high modulus by providing a cabled yarn in which an aramid hybrid Z-twisted yarn composed of an aramid multifilament yarn and an aramid spun yarn; and a general-purpose Z-twisted yarn are S-twisted together. There is also provided a method for manufacturing the same.
