Latex reinforced waste buffing dust-jeans cotton composites and its characterization.

This study aims to fabricate flexible composite sheets from waste buffing dust and post-consumer cotton waste through a simple solution casting technique. Natural rubber latex (NRL) was used as a binder material in different mixing ratios. To validate the chemical bonding between buffing dust and cotton fiber, FTIR was performed. Thermal stability of as-prepared composites was confirmed through TGA and DTA studies., The surface tropology of fabricated composites, were examined by FESEM analysis. From the results of oxygen gas transmittance rates, it was found that prepared composites possess enhanced gas barrier properties as compared to pure buffing dust. The physical and mechanical properties such as tensile strength, elongation, hardness, and density of prepared composites with optimum NRL content were augmented by 58, 48, 35, and 21%, respectively, as compared to pure buffing dust sheets. Thereby, these simple, low cost and flexible composite sheets would be a promising material for packaging as well as interior decoration industries. [ABSTRACT FROM AUTHOR]
