卫生巾材质可降解性的探讨

Biodegradability of the Components of Sanitary Napkins

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 35 d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。

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.
