Beschreibung
Zusammenfassung:	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 cord-fiber-woven product in which the synthetic long fiber multifilament yarns have been 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 cord-fiber-woven product bundles obtained to a specified length. 提供使摩擦传动行为稳定化、进步提高了行进寿命的传动带用的、含短纤维橡胶组合物用的、橡胶加强用短纤维。种短纤维，其特征在于，其为经粘接剂处理的合成长纤维复丝纱的切断物且分散在橡胶组合物中来使
