Abstract
本发明公开了一种可降解防护服。该可降解防护服采用可降解无纺布制作得到，所述可降解无纺布含以下重量百分比的组分：聚乳酸50～70％、聚己内酯20～30％和聚乙烯10～20％。与现有技术相比，本发明的可降解防护服具有良好的强度和生物降解性，降低废弃防护服填埋处理对环境的危害。
Description
技术领域
本发明涉及一种可降解防护服及其制作方法。
背景技术
突如其来的新型冠状病毒肺炎疫情使得防护服的使用量剧增，也造成大量废弃的防护服，一般可通过焚烧、化学或高温消毒后填埋等方式对这些废弃防护服进行无害化处理。现有防护服产品主要采用PE、PP、PU无纺布面料，这些面料的可降解性差，消毒后直接填埋处理会长期存在土壤中造成二次污染，焚烧又会对空气造成二次污染。
发明内容
基于现有防护服的不足，本发明的目的在于提供一种可降解防护服及其制作方法。
为实现上述目的，本发明采用的技术方案如下：
一种可降解防护服，其特点在于：所述可降解防护服采用可降解无纺布制作得到，所述可降解无纺布含以下重量百分比的组分：
聚乳酸50～70％、聚己内酯20～30％和聚乙烯10～20％。
优选地，所述可降解无纺布的克重为70～90克/平方米。
上述可降解防护服的制作方法，包括以聚乳酸、聚己内酯纤维和聚乙烯为纤维原料，经熔融、喷丝、成网、加固、裁剪、缝合，制成防护服。
优选地，喷丝时控制纤维的直径为2～10微米。
优选地，采用针刺方式加固。
具体实施方式
以下结合实施例对本发明的技术方案做进一步详细说明。
本发明所述可降解防护服是采用可降解无纺布制作得到，该可降解无纺布含以下重量百分比的组分：聚乳酸50～70％、聚己内酯20～30％和聚乙烯10～20％。依《纺织品非织造布可生物降解性能的评价二氧化碳释放测定法》GB/T33616—2017测得该可降解无纺布90天的生物降解率达到80％左右。
聚乳酸、聚己内酯和聚乙烯均为可降解高分子，聚己内酯具有较低的熔点温度60℃左右，在无害化处理时较低的温度即可破坏防护服的结构，分解成碎片，聚乙烯能提高无纺布的强度。
实施例1
可降解防护服的制作过程包括以下步骤:
(1)将聚乳酸母粒、聚己内酯母粒和聚乙烯母粒干燥；
(2)再将干燥的聚乳酸母粒、聚己内酯母粒和聚乙烯母粒分别喂入螺杆挤压机熔融挤出；
(3)按聚乳酸70重量份、聚己内酯20重量份和聚乙烯10重量份，将熔融物混合后从纺丝板挤出，通过气流牵伸至铺网机，克重控制在80克/平方米左右，纤维直径控制在6微米左右；
(4)成网后，采用针刺法加固，得到无纺布；
(5)按设计规格，按常规方法对无纺布进行裁剪、缝合，得到可降解防护服。
实施例2
可降解防护服的制作过程包括以下步骤:
(1)将聚乳酸母粒、聚己内酯母粒和聚乙烯母粒干燥；
(2)再将干燥的聚乳酸母粒、聚己内酯母粒和聚乙烯母粒分别喂入螺杆挤压机熔融挤出；
(3)按聚乳酸60重量份、聚己内酯25重量份和聚乙烯15重量份，将熔融物混合后从纺丝板挤出，通过气流牵伸至铺网机，克重控制在80克/平方米左右，纤维直径控制在8微米左右；
(4)成网后，采用针刺法加固，得到无纺布；
(5)按设计规格，按常规方法对无纺布进行裁剪、缝合，得到可降解防护服。
实施例3
可降解防护服的制作过程包括以下步骤:
(1)将聚乳酸母粒、聚己内酯母粒和聚乙烯母粒干燥；
(2)再将干燥的聚乳酸母粒、聚己内酯母粒和聚乙烯母粒分别喂入螺杆挤压机熔融挤出；
(3)按聚乳酸50重量份、聚己内酯30重量份和聚乙烯20重量份，将熔融物混合后从纺丝板挤出，通过气流牵伸至铺网机，克重控制在80克/平方米左右，纤维直径控制在3微米左右；
(4)成网后，采用针刺法加固，得到无纺布；
(5)按设计规格，按常规方法对无纺布进行裁剪、缝合，得到可降解防护服。
最后应说明的是：以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
