Abstract
本发明涉及一种医用口罩的生产工艺，包括选料、裁剪、叠合、裁断复合、安装耳带、消毒包装。本发明通过在中上层熔喷无纺布内侧设置活性炭过滤纸实现对吸入空气中的细菌和颗粒物杂质的初步吸附，从而提高了吸入空气中杂质的过滤作用，通过水洗抗静电剂提高了口罩的抗静电能力，提高人体佩戴口罩时的舒适性。无需额外添加抗菌剂或者进行抗菌处理即具备抗菌性，并且口罩在废弃后能够被生物降解，避免对环境造成污染。
Description
技术领域
本发明涉及一种口罩的生产工艺，尤其是涉及一种医用口罩的生产工艺。
背景技术
口罩是一种卫生用品，一般指戴在口鼻部位用于过滤进入口鼻的空气，以达到阻挡有害的气体、气味、飞沫、病毒等物质的作用，以纱布或纸等材料做成，口罩对进入肺部的空气有一定的过滤作用，在呼吸道传染病流行时，在粉尘等污染的环境中作业时，戴口罩具有非常好的作用，口罩可分为空气过滤式口罩和供气式口罩。
而一次性使用医用口罩适用于覆盖使用者的口、鼻及下颌，用于普通医疗环境中佩戴、阻隔口腔和鼻腔呼出或喷出污染物的一次性使用口罩，在现阶段的医用口罩中，存在过滤性能有待于提高的问题，同时，多数医用口罩仅具有过滤空气中杂质的作用，不具备抗菌的性能，在长时间佩戴的过程中，易造成细菌的滋生。
发明内容
为了克服上述缺陷，本发明提供了一种医用口罩的生产工艺。
本发明解决其技术问题所采用的技术方案是：一种医用口罩的生产工艺，包括以下步骤：
步骤一、选料：
选择制作口罩的面料，分别为外层纺粘无纺布、中上层熔喷无纺布、活性炭过滤纸、中下层熔喷无纺布和下层纺粘无纺布，其中外层纺粘无纺布内部等距设置有若干个鼻夹条；
步骤二、裁剪：
对外层纺粘无纺布、中上层熔喷无纺布、活性炭过滤纸、中下层熔喷无纺布和下层纺粘无纺布进行裁剪，使其宽度与口罩的宽度相一致；
步骤三、叠合：
将外层纺粘无纺布、中上层熔喷无纺布、活性炭过滤纸、中下层熔喷无纺布和下层纺粘无纺布按照由上至下的顺序依次叠放在一起，随后将叠放完成的材料，放入压合机内进行压合处理形成口罩本体，确保鼻夹条位于口罩本体的中心位置处；
步骤四、裁断：
将整平处理完成的材料放入自动裁断机内，进行裁断处理，然后将裁断处理完成的成型口罩两个长边进行缝边处理；
步骤五、复合：
将口罩本体的前后侧边进行压实后焊接，将口罩本体的左右侧边进行压实后焊接；
步骤六、安装耳带：
将耳带的两端分别放在裁断和焊接处理完成的成型口罩本体两侧相对应的位置，然后通过耳带焊接机实现耳带与成型口罩之间的连接；
步骤七、消毒包装：
将口罩成品进行包装，然后置于消毒室内消毒。
在本发明的一个较佳实施例中，所述外层纺粘无纺布和所述下层纺粘无纺布上均涂覆有水洗抗静电剂。
在本发明的一个较佳实施例中，所述水性抗静电剂由十二烷基苯磺酸钠溶于水制成。
在本发明的一个较佳实施例中，消毒室中通入环氧乙烷气体进行消毒，然后通空气和氮气去稀释和排走环氧乙烷气体实现解析。
在本发明的一个较佳实施例中，步骤七中的包装是在无菌环境下进行的。
本发明的有益效果是：本发明通过在中上层熔喷无纺布内侧设置活性炭过滤纸实现对吸入空气中的细菌和颗粒物杂质的初步吸附，从而提高了吸入空气中杂质的过滤作用，通过水洗抗静电剂提高了口罩的抗静电能力，提高人体佩戴口罩时的舒适性。无需额外添加抗菌剂或者进行抗菌处理即具备抗菌性，并且口罩在废弃后能够被生物降解，避免对环境造成污染。
