Abstract

The growing attention to environmental responsibility in the textile and apparel industry necessitates the development of innovative and sustainable manufacturing technologies. This study presents an energy- efficient processing technology aimed at improving cotton processing efficiency, focusing on optimizing the design of ginning saws. Using a comprehensive design methodology, key processing parameters, such as cutting speed, feed rate, tool-material interaction, and machine dynamics, were carefully optimized to meet sustainability goals. To ensure improvements that minimize energy consumption and environmental impact, the behavior of cotton fibers and the influence of environmental conditions on processing performance were considered. A new method for modeling and generating an optimized ginning saw tooth profile is presented, resulting in improved cutting efficiency, reduced fiber damage, and increased tool life. The results demonstrate that this method not only improves productivity but also facilitates the adoption of more environmentally friendly manufacturing practices by reducing resource consumption and improving manufacturing sustainability. This research contributes to the development of environmentally responsible production strategies in the textile and clothing industry, thereby contributing to the achievement of broader environmental goals.
