마찰 전동 거동이 안정화되고, 주행 수명을 한층 더 향상시킨 전동 벨트용의, 단섬유 함유 고무 조성물용의, 고무 보강용 단섬유의 제공. 접착제 처리된 합성 장섬유 멀티필라멘트사의 절단물인, 고무 조성물 중에 분산시켜 이용하는 단섬유로서, 단사(單絲)의 접착제 미처리 개수의 비율이 0∼5%인 것을 특징으로 하는 상기 단섬유, 및 이하의 공정: 합성 장섬유 멀티필라멘트사를 코드직조한 코드 직물을 접착제 처리액에 침지한 후, 닙롤에 의해 1.2∼5.0 ㎫의 닙압으로 가압하는 공정, 및 얻어진 코드 직물의 다발을 소정 길이로 절단하는 공정을 포함하는 상기 단섬유의 제조 방법. Provided is a short rubber reinforcement fiber for short fiber-containing rubber compositions that are used for transmission belts for which friction transmission behavior has been stabilized and travel service life has been further improved. The present invention is: a short fiber, which is the product of cutting an adhesive-treated synthetic long fiber multifilament yarn and is used by dispersing in a rubber composition, the short fiber being characterized in that the percentage of the number of non-adhesive-treated single yarns is 0-5%; and a method for manufacturing said short fibers, the method comprising a step for immersing a sudare-woven product in which the synthetic long fiber multifilament yarns have been sudare-woven in an adhesive treatment solution and then pressing at a nip pressure of 1.2-5.0 MPa using nip rolls, and a step for cutting the sudare-woven product bundles obtained to a specified length.
