摘　　要：采用具有优良吸水保水性能的可降解超吸水树脂(super absorbent polymer,SAP),以聚乳酸(polylactic acid,PLA)针刺非织造材料作为包覆,制得低成本、无污染的条带状SAP-PLA沙漠治理材料。对PLA针刺材料各项物理性能进行评估,并在模拟的沙漠环境中对比观察有无使用SAP-PLA沙漠治理材料时的草籽生长情况。结果表明:该PLA针刺材料的物理性能满足使用要求,在模拟沙漠环境中,放置了SAP-PLA沙漠治理材料的试验区域的植株密度达到了895株/m2,而空白对照区域无植株生长。A low cost,environmental-friendly tubular SAP-PLA desertification control material was produced by incorporating super absorbent polymer(SAP) which has excellent water absorption property into polylactic acid(PLA) nonwovens.We analyzed the physical properties of PLA needle-punched materials,and observed the growth of grass seeds in the simulated desert environment with and without SAP-PLA material.The results show that the physical properties of PLA nonwovens meet the using requirements.The grass density in the experiment area reaches 895 plants per square meter when using the SAP-PLA material,while there is no any plant in the blank group.
