Abstract: Proposed is a non-slip outsole composition containing coconut fiber. The composition contains 30 to 40 parts by weight of polybutadiene rubber, 20 to 30 parts by weight of elastomer, 15 to 20 parts by weight of filler, 20 to 30 parts by weight of coconut fiber, 0.1 to 1 part by weight of surfactant, 0.2 to 1 part by weight of a vulcanization accelerator, and 0.5 to 2 parts by weight of a cross-linking agent. Further proposed is a manufacturing method of a non-slip outsole containing coconut fiber. The method includes preparing the coconut fiber by separating a coconut into a cocopeat part and a coconut fiber part, blending a non-slip outsole composition by mixing the prepared coconut fiber with a rubber binder mixture, and producing the non-slip outsole through molding by injecting the non-slip outsole composition into a mold having a predetermined outsole shape, and finishing the non-slip outsole by cooling and aging the molded outsole.
