A Novel Approach of Manufacturing Sustainable Seamless Jute Bags and Evaluation of Its Properties: A Comparative Study with Commercial Bags

ABSTRACT

To reduce the adverse impact of synthetic bags on carbon footprints, greenhouse gases, and global warming, there is a rising demand for biodegradable and sustainable packaging material, especially for packing crops and food. Bags made from natural fibers are the finest alternative to synthetic ones. Jute is one of the most in-demand natural fibers in the packaging industry. Nevertheless, the traditional production method is more process-oriented, requiring more time and resulting in more expensive bags. Bowing problems induced by side seams cause sack bundles to roll during transport, which is also another issue. This study describes a unique process for producing seamless jute bags and sacks, eliminating the current processes in favor of fewer processes. A mechanical left-handed dobby loom with a cutting arrangement for separating the sacks produced continuous sack weaving. The tensile and seam strength of the produced sacks were evaluated and found to be comparable to those of commercially available sacks. In addition, one-way ANOVA and regression studies demonstrated the results significance. This developed method will increase productivity while reducing energy consumption, resulting in inexpensive packaging products and a solution to the transportation issue.

摘要

为了减少合成袋对碳足迹、温室气体和全球变暖的不利影响，对可生物降解和可持续包装材料的需求不断增加，尤其是对作物和食品的包装材料. 由天然纤维制成的袋子是合成袋子的最佳替代品.黄麻是包装行业中需求量最大的天然纤维之一. 然而，传统的生产方法更注重工艺，需要更多的时间，并导致更昂贵的袋子. 侧缝引起的弯曲问题会导致麻袋捆在运输过程中滚动，这也是另一个问题. 这项研究描述了一种生产无缝黄麻袋和麻袋的独特工艺，取消了目前的工艺，转而采用更少的工艺. 一种带切割装置的机械左手多臂织机，用于分离麻袋，生产连续的麻袋编织. 对所生产的麻袋的拉伸强度和接缝强度进行了评估，发现其与市售麻袋的拉伸和接缝强度相当. 此外，单因素方差分析和回归研究证明了结果的显著性. 这种开发的方法将提高生产力，同时减少能源消耗，从而生产出价格低廉的包装产品，并解决运输问题.
