将第三纤维气流成网后对网状结构进行热压粘合得到第三纤网层。
进一步地，所述底层的制备方法为：将聚己二酸/对苯二甲酸丁二酯和聚羟基脂肪酸酯按照2:1的比例混合并搅拌得到第三混合材料；
利用第三混合材料制成第三母粒，并对第三母粒进行纺丝制成第三纤维；
将第三纤维气流成网后，对网状结构进行热压粘合得到底层。
进一步地，所述聚羟基戊酸酯的质量份为5-10份，聚羟基丁酸酯的质量份为5-10份，聚乳酸的质量份为20-30份。

进一步地，聚丁二酸丁二醇脂的质量份为5-10份，聚己内酯的质量份为15-20份，竹炭粉的质量份为1-5份。
进一步地，所述分子筛的制备方法为将金银花、绿茶叶和沸石磨成粉，按照1:1:4的比例进行混合，混合后挤出造粒得到分子筛颗粒；将分子筛颗粒置于薄荷提取物中在20-30℃的温度下浸泡1-2小时后，以5℃/min的速率升温至50-60℃，恒温保持1小时后取出冷却至室温，对冷却至室温的分子筛颗进行晾干处理得到分子筛。
本发明多层组合生物降解芯体制备方法，通过制备的第一纤网层、第二纤网层和第三纤网层能够提高芯体的吸湿性能，通过在第一纤网层和第二纤网层中间填充分子筛，能够去除异味，通过在第二纤网层和第三纤网层中间填充可生物降解高吸水性树脂，进一步提高了芯体的吸水能力，使其更加舒适，与此同时，本发明中的第一纤网层、第二纤网层和第三纤网层均由可降级材料制得，使用之后能够在一定的时间内降解，减少了对的环境污染，较为环保。
为达到上述目的，本发明一种多层组合生物降解芯体，按照上述的多层组合生物降解芯体制备方法制得。
本发明多层组合生物降解芯体，通过设置的第一纤网层、第二纤网层和第三纤网层能够提高芯体的吸湿性能，通过在第一纤网层和第二纤网层中间填充分子筛，能够去除异味，通过在第二纤网层和第三纤网层中间填充可生物降解高吸水性树脂，进一步提高了芯体的吸水能力，使其更加舒适。
