摘要(Abstract):
将聚乳酸(PLA)、聚对苯二甲酸丙二酯(PTT)和聚苯硫醚(PPS)纤维置于自然环境中,经过数十天的风吹日晒和水淹土埋后,分别测定了它们的失重率和强度损失率,定性分析总结了其自然降解性能,为关注这些新纤维生产和应用过程的环境友好问题提供了参考。
Measure the weightlessness rate and loss rate of strength respectively after putting polylactic acid ester(PLA), poly(propylene terephthalate)(PTT) and polyphenylene sulfide(PPS) fiber in the natural environment for dozens of days of exposing to the sun, water and burying in the soil. Through analysis and summarizes of the natural degradation performance, it can provide the reference to the new environmental friendly production and application of these new fibers.
