卫生巾材质可降解性的探讨

本研究通过对国产12个品牌的卫生巾材质的成份鉴别、可生物降解性实验分析，得出使用过后的各类卫生巾，用土壤填埋的方法处理，降解周期在35d时，其可降解性最大，平均达到35％；组成卫生巾的主要成份棉纤维、粘胶纤维、涤纶纤维和丙纶纤维在相同条件下，可降解性依次为：棉纤维＞粘胶纤维＞涤纶纤维＞丙纶纤维，并指出天然纤维材质是环保型卫生巾发展的方向。

Biodegradability of the Components of Sanitary Napkins

The research based on the identification of the components and experimental analysis of biodegradability in 12 brands sanitary napkins made at home.As a result,when degradability period was 35 days,all varieties of sanitary napkins which were used should be buried in soil,the efficiency of degradability were average up to 35%,degradability was the best;Sanitary napkins were mainly composed of cottony fibre,mucilage fiber,terylene fibre and polypropylene fibre while under the same conditions,biodegradability prority was:cottony fibre>mucilage fibre>terylene fibre>polypropylene fibre,and we pointed out natural faric is direction of development about environment protection from sanitary napkins.
