With the aim to develop biodegradable quality sanitary pads at affordable prices to the schoolgirls and women, locally available cotton waste materials and anti-bacterial nanocolorants are used to prepare anti-bacterial biodegradable absorbent material suitable for sanitary napkins and diapers. Cotton fluff from loom waste was collected, cleaned and hydro-entangled to form absorbent sheet. The sheet shows water absorbency of more than 470%. Electrochemically synthesized natural extract (from neem and orange peel) based nanocolorants were incorporated in the material to improve their anti-bacterial ability. Further, microporous polylactic acid biodegradable sheet was used to pack the absorbent layer and its performance was tested. This anti-bacterial biodegradable absorbent pad would be an ideal substitute for synthetic sanitary pads considering its 100% biodegradability. This can provide a long-term viable alternative to the current practices.

来自废棉和天然提取物的抗菌纳米着色剂的可生物降解纤维素卫生巾

为了开发出价格适中、价格实惠的可生物降解优质卫生巾给女学生和女性，利用当地可用的棉花废料和抗菌纳米着色剂制备适用于卫生巾和尿布的抗菌可生物降解吸收材料。收集、清洁和水力缠结来自织机废料的棉绒以形成吸收性片材。该片材显示出超过 470% 的吸水率。电化学合成的天然提取物（来自印楝和橙皮）基于纳米着色剂被纳入材料中，以提高它们的抗菌能力。此外，使用微孔聚乳酸可生物降解片材填充吸收层并测试其性能。考虑到其 100% 的生物降解性，这种抗菌可生物降解的吸收垫将是合成卫生巾的理想替代品。这可以为当前的做法提供一个长期可行的替代方案。
