The increasing environmental concerns surrounding synthetic fibers, particularly their contribution to microplastic pollution are driving research toward sustainable alternatives. This study explores the processing, thermal, mechanical, and environmental characteristics of melt-spun biodegradable fibers derived from various biodegradable polymers, including polylactic acid (PLA), polyglycolic acid (PGA), polyhydroxyalkanoates (PHA), polybutylene succinate (PBS), polycaprolactone (PCL), and some copolymers. The melt-spinning process was optimized to address challenges such as thermal degradation, low melt strength, and crystallization limitations. The resulting fibers were analyzed for their mechanical properties, thermal behavior, and biodegradation potential under different environmental conditions, including composting and weathering assessments. The findings indicate that fiber performance is highly dependent on the polymer structure and processing parameters, with PLA and PGA demonstrating superior tensile properties and crystallization behavior, whereas PHA and most copolymers exhibited processing limitations or low-tenacity fibers. The results provide some insights into the development of high-performance biodegradable fibers suitable for textile and technical applications, paving the way for sustainable alternatives to conventional synthetic fibers.
围绕合成纤维日益增长的环境问题，尤其是它们对微塑料污染的贡献，正推动着对可持续替代品的研究。本研究探讨了由各种可生物降解聚合物制成的熔喷可生物降解纤维的加工、热、机械和环境特性，这些聚合物包括聚乳酸（PLA）、聚乙醇酸（PGA）、聚羟基脂肪酸酯（PHA）、聚丁二酸丁二醇酯（PBS）、聚己内酯（PCL）以及一些共聚物。对熔纺工艺进行了优化，以应对热降解、熔体强度低和结晶限制等挑战。对所得纤维在不同环境条件下的机械性能、热行为和生物降解潜力进行了分析，包括堆肥和耐候性评估。研究结果表明，纤维性能高度依赖于聚合物结构和加工参数，PLA和PGA表现出优异的拉伸性能和结晶行为，而PHA和大多数共聚物则表现出加工限制或低强度纤维。这些结果为开发适用于纺织和技术应用的高性能可生物降解纤维提供了一些见解，为传统合成纤维的可持续替代品铺平了道路。
