To provide a method for modifying the surface of aramid fibers, where the method modifies the surface of aramid fibers and increases the adhesion of the fiber surface to elastomer materials.SOLUTION: There is provided a method for modifying the surface of an aramid fiber, the method including (a) subjecting the aramid fiber to a tensile force; (b) bending the aramid fiber at an angle of greater than 30°; and (c) releasing the aramid fiber from the tensile force.SELECTED DRAWING: None 【課題】アラミド繊維表面を改質し、繊維表面のエラストマー材料への接着性を高める、アラミド繊維表面の改質方法を提供することである。【解決手段】アラミド繊維表面の改質方法であって、ａ．前記アラミド繊維に張力を加えることと、ｂ．前記アラミド繊維を、３０°より大きな角度で曲げて、前記アラミド繊維の表面を改質することと、ｃ．前記アラミド繊維にかかる前記張力をゆるめることと、を含む方法である。【選択図】なし
