The present invention relates to a polyamide multifilament fiber for a tire cord and a tire cord containing the same, wherein the polyamide multifilament fiber contains a bio-based polyamide and a copper compound added to the polyamide such that a copper concentration is 30 to 300 ppm, and the polyamide multifilament fiber has a yarn sulfuric acid relative viscosity of 2.5 to 5, yarn strength of 8 g/d or more, and yarn degree of orientation of 50x10^-3 or more. According to the present invention, the polyamide multifilament fiber for a tire cord, the tire cord and a tire, which are eco-friendly by using bio-based materials, and have excellent strength and dimensional stability, can be obtained.

    본 발명은 바이오-기반 폴리아미드(bio-based polyamide)와 상기 폴리아미드에 대하여 구리 농도가 30~300 ppm이 되도록 첨가되는 구리 화합물을 포함하고, 원사 황산 상대점도 2.5~5, 원사 강도 8 g/d 이상, 원사 배향도 50x10-3 이상인 것을 특징으로 하는 타이어 코드용 폴리아미드 멀티필라멘트 섬유 및 이를 포함하는 타이어 코드에 관한 것으로, 본 발명에 의하면 바이오-기반 재료를 이용하여 친환경적이면서도, 강도 및 형태안정성이 우수한 타이어 코드용 폴리아미드 멀티필라멘트 섬유, 타이어 코드 및 타이어를 얻을 수 있다.
