Effect of Fiber Surface Modification on Properties of Artificial Leather from Leather Fiber Filled Natural Rubber Composites

Abstract:

Artificial leather based on natural rubber (NR) filled with leather fibers was prepared using a hot pressing process. The leather fiber was obtained by shredding chrome-tanned leather into fibers with the sizes of 20-mesh. Three different modifying agents (i.e., 1% aqueous solutions of sodium hydroxide, urea, and sodium bicarbonate) were used in the modification of leather fibers. Mechanical properties of NR composites filled with 100 phr of modified or unmodified leather fibers were then investigated. The results showed that cure characteristics, tensile properties, tear strength and abrasion resistance of the composite combined with the modified leather fibers were clearly improved, compared to those of the simple unmodified leather fiber composite. Furthermore, interfacial adhesion between the leather fiber and natural rubber was found to improve. From this study, the result suggested that the urea solution provided the best property improvement when the other modifying agents were compared with.
