A nonwoven fabric layer to be attached, wherein the bottom layer and the top layer are each thermally bonded to the nonwoven fabric layer, having an improved anti-slip function shoe sole that can be easily attached to the shoe upper and its manufacturing method will be.
일반적으로 신발은 발등을 에워싸는 갑피와 상기 갑피의 하면에 부착되어 지면에 접촉하는 밑창으로 이루어지는데, 상기 밑창은 지면에 접촉하여 지면에 의한 영향을 일차적으로 전달받으므로 상기 밑창은 충격완화 및 미끄럼 방지기능을 가져야 한다.In general, the shoe is composed of an upper surrounding the instep and the sole attached to the lower surface of the upper and the sole in contact with the ground, the sole is in contact with the ground primarily receives the influence of the ground, the sole is shock-absorbing and non-slip Must have a function
아래 표시한 특허문헌을 참조하면, 종래의 신발 밑창은 합성고무(범용고무)로 제조되어 접착제에 의해 갑피에 부착되는데, 미끄럼 방지 기능에 한계가 있다. 특히, 바위가 많은 산을 오를 때 신는 등산화, 암벽화 등에 사용할 수 없는 문제가 있다.Referring to the patent document indicated below, the conventional shoe sole is made of synthetic rubber (general purpose rubber) and attached to the upper by an adhesive, there is a limit to the non-slip function. In particular, there is a problem that can not be used for climbing, rock climbing, etc. when climbing a rocky mountain.
