合成纤维织物的生物可降解性能研究

Biodegradability of synthetic fiber soil landfill

生物降解助剂有助于提高合成纤维的生物可降解性能。在合成纤维的纺丝生产过程中添加适当的生物降解助剂,并将获得的纤维进行纺织加工即可获得生物降解纺织品。通过对添加不同质量分数降解助剂的聚酰胺针织物和聚丙烯非织造布进行填埋试验,测试其不同填埋时间的质量损失率、红外光谱和表面形态等,结果表明纺织品在添加降解助剂后降解效果明显,理论上可降解到自然环境中。

Biodegradable additives can improve the biodegradability of chemical fiber.Biodegradable textile can be fabricated by the biodegradable fiber which was produced by adding biodegradable additives in the process of fiber production.By means of weight loss rate,infrared spectrum analysis,scanning electron microscope analysis and other test methods,the results showed that the degradation effect of textiles is obvious after adding degradation additives,which can be degraded into the natural environment theoretically.
