Study on the Manufacturing process and Characteristics of Non-slip Outsoles Using Fiber-phase Structure of Leather Waste

Abstract

This study deals with developing materials using waste leather and binders for sustainable material development by replacing butyl rubber, which is currently entirely dependent on imports. Since butyl rubber has few double bonds, the production efficiency is low because of the slow speed in the vulcanization process. Since the temperature of the process must be increased, an alternative material is required. Industries and research institutes are currently studying outsole pattern application and rubber mixing to replace butyl rubber, but technology development using recycled products is currently unavailable. This study developed an outsole material according to the type of rubber binder and the fibrous length of the leather waste. The bonding characteristics, crosslinking characteristics, abrasion resistance, and slip characteristics of the developed material were studied.
