Description

一种可生物降解卫生袋制作工艺及卫生袋
技术领域
本发明涉及卫生袋制作技术领域，具体地，涉及一种可生物降解卫生袋制作工艺及卫生袋。
背景技术
袋子，是人们日常生活中必不可少的物品，常被用来装其他物品。现有的袋子大多以塑料(常用聚丙烯、聚酯、尼龙等)为主要原料制成，因其廉价、重量极轻、容量大、便于收纳的优点被广泛使用。但又因塑料袋降解周期极长、处理困难的缺点而被部分国家禁止生产和使用。随着生态环保要求越来越高，一些塑料袋逐渐被禁止生产、销售、使用。虽然一些塑料袋对环保不利，但由于袋子的便利性，人们仍对袋子有很大的需求。
发明内容
本发明的目的在于提供一种可生物降解卫生袋的制作工艺，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种可生物降解卫生袋制作工艺，包括以下具体步骤：
S1.以含淀粉的农产品为原料，将其中的淀粉经过发酵制得乳酸，再将乳酸经过化学合成聚合成聚乳酸；
S2.将聚乳酸熔融纺丝制作聚乳酸纤维材料，分别得到聚乳酸纤维膜、聚乳酸纤维无纺布；
S3.以聚乳酸纤维无纺布作为内层材料、以聚乳酸纤维膜作为外层材料，通过热压使内层材料与外层材料溶合；
S4.将溶合材料制作成袋坯，再采用热压方式对袋坯进行封口、封边处理，制成成品卫生袋。
为更好地说明本发明，这里还提供了一种由上述工艺制作的卫生袋，包括内层、外层，所述内层采用聚乳酸纤维无纺布，所述外层采用聚乳酸纤维膜，所述内层与外层通过热压方式溶合，所述卫生袋底部、侧边分别采用热压方式进行封口、封边。
为便于旅行容纳的垃圾、呕吐物等，优选的，所述卫生袋上部设有一端短、一端长的V形结构。
为提升袋口抗牵拉的强度，优选的，所述卫生袋的上部下方设有一圈加强带，所述加强带采用聚乳酸纤维无纺布材质。
为提升产品的吸水性，优选的，所述内层采用三层聚乳酸纤维无纺布。
为了提升卫生袋的吸水性，进一步的，所述内层与外层之间还设置有吸水棉层。
与现有技术相比，本发明的有益效果是：本发明所述的可生物降解卫生袋制作工艺及卫生袋，通过从可再生植物玉米、土豆、木薯中提取淀粉制作可降解的聚乳酸材料，并制作得到聚乳酸纤维，并进一步制作成可降解的卫生袋，生产出的产品具有较强的吸水功能，并且不会漏水，方便使用和携带，实现卫生袋能生物堆肥降解，最终在土壤或海水中经微生物作用分解为二氧化碳和水，且燃烧时不会散发毒气，不会造成污染，具有干净卫生、生态环保、使用方便、成本较低等特点。
