The present invention relates to a polyketone used in a fuel tube for an automobile, and especially, to a fuel tube for an automobile, which comprises: a first layer of polyamide; a second layer comprising a linear alternating polyketone copolymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon; and a third layer of polyamide. The fuel tube for the automobile of the present invention can overcome the disadvantage that the conventional EvOH adhesive force is low, and thus an adhesive layer is not required to have excellent gas barrier properties, airtightness and impact resistance while reducing the thickness of the fuel tube.

    본 발명은 자동차용 연료 튜브에 쓰이는 폴리케톤에 관한 것으로, 특히 폴리아미드를 제1층; 일산화탄소와 적어도 1종의 에틸렌계 불포화 탄화수소로 이루어진 선상 교대 폴리케톤 공중합체를 제2층; 폴리아미드를 제3층; 으로 가지는 자동차 연료 튜브에 관한 것이다. 본 발명의 자동차용 연료 튜브는 종래의 EvOH의 접착력이 낮다는 단점을 극복할 수 있어 접착층이 필요하지 않아 연료 튜브의 두께를 줄일 수 있으면서도 우수한 가스차단성, 기밀성 및 내충격성을 가진다.
