The pressing need for sustainable materials has driven considerable research into biocomposites that marry natural fibers and biodegradable polymers. This study focuses on an eco-conscious solution by combining jute fabric and polylactic acid (PLA) via the compression molding technique. Unique to this work is the evaluation of three distinct jute fabric weave patterns—plain 1/1, twill 2/2, and sateen 1/4—as reinforcement in the PLA matrix. This study encompasses an exhaustive methodology, including the production of jute fabric on a handloom machine, yarn and fabric property assessments, alkali treatment protocols, and crimp percentage evaluations. Mechanical characterization of the composites revealed significant enhancements in tensile, flexural, and compressive strengths upon the inclusion of jute fabric. Alkali treatment served as a catalyst for further improvements. Distinctive findings were made regarding the impact of weave patterns on mechanical performance. Specifically, the plain 1/1 weave exhibited the highest crimp percentage but yielded lower mechanical properties. In contrast, the sateen 1/4 weave emerged superior in mechanical evaluations, even outperforming neat PLA samples. This superior mechanical integrity is attributed to sateen’s weave architecture, which distributes tensile loading across multiple yarns, enhancing its resistance to failure. The twill 2/2 weave also demonstrated increased mechanical properties over the plain 1/1 weave, establishing the critical role of weave pattern and fabric density in dictating composite performance. Given these results, the study suggests a hierarchy in mechanical performance among the tested weaves, potentially guiding future research and applications in sustainable composite materials. Overall, this study focuses on critical insights into how natural fibers, when adequately processed and woven, can dramatically elevate the mechanical properties of biodegradable polymers, thereby leading the way toward a new generation of eco-friendly, yet mechanically robust, composite materials.

摘要

The pressing need for sustainable materials has driven considerable research into biocomposites that marry natural fibers and biodegradable polymers. This study focuses on an eco-conscious solution by combining jute fabric and polylactic acid (PLA) via the compression molding technique. Unique to this work is the evaluation of three distinct jute fabric weave patterns—plain 1/1, twill 2/2, and sateen 1/4—as reinforcement in the PLA matrix. This study encompasses an exhaustive methodology, including the production of jute fabric on a handloom machine, yarn and fabric property assessments, alkali treatment protocols, and crimp percentage evaluations. Mechanical characterization of the composites revealed significant enhancements in tensile, flexural, and compressive strengths upon the inclusion of jute fabric. Alkali treatment served as a catalyst for further improvements. Distinctive findings were made regarding the impact of weave patterns on mechanical performance. Specifically, the plain 1/1 weave exhibited the highest crimp percentage but yielded lower mechanical properties. In contrast, the sateen 1/4 weave emerged superior in mechanical evaluations, even outperforming neat PLA samples. This superior mechanical integrity is attributed to sateen’s weave architecture, which distributes tensile loading across multiple yarns, enhancing its resistance to failure. The twill 2/2 weave also demonstrated increased mechanical properties over the plain 1/1 weave, establishing the critical role of weave pattern and fabric density in dictating composite performance. Given these results, the study suggests a hierarchy in mechanical performance among the tested weaves, potentially guiding future research and applications in sustainable composite materials. Overall, this study focuses on critical insights into how natural fibers, when adequately processed and woven, can dramatically elevate the mechanical properties of biodegradable polymers, thereby leading the way toward a new generation of eco-friendly, yet mechanically robust, composite materials.
