The present invention relates to a lyocell heat treatment cord with improved fatigue resistance. A lyocell filament is obtained by: dissolving cellulose in an NMMO hydrate by using a solvent; adding an additive of a glycerol structure; and appropriately controlling spinning, washing, emulsion treatment, and drying conditions of the solution. Twist yarn production and heat treatment are carried out by using the filament to provide the lyocell heat treatment cord with improved fatigue resistance, particularly suitable for a tire cord. According to a preferred embodiment of the present invention, provided is a radial pneumatic tire using the lyocell heat treatment cord on a carcass layer or a cap ply layer in a one-layer structure or a two-layer structure.

    본 발명은 NMMO 수화물을 용매를 사용하여 셀룰로오스를 용해시키고 글리세롤 구조의 첨가제를 첨가한 후, 상기 용액의 방사, 수세, 유제처리 및 건조 조건을 적절히 조절함으로써 산업용 라이오셀 필라멘트를 얻고 이를 이용하여 연사 및 열처리를 실시함으로써 특히 타이어코드용으로 적합한 내피로도가 향상된 라이오셀 열처리 코드를 제공하는 것에 관한 것이다. 또한 본 발명의 적절한 실시형태에 따르면 상기 라이오셀 열처리 코드를 카카스 층 또는 캡 플라이 층에 1층 또는 2층 구조로 사용한 래디얼 공기입 타이어가 제공된다.
