Abstract

Plastic, in all its forms, always harms the environment, humans, and other living organisms. The coronavirus situation exacerbates the use of plastic products more than at any other time, of which surgical masks contribute to plastic pollution the most. These masks spread to terrestrial and aquatic environments, where they break down into even more noxious microplastics. These microplastics enter the human food chain through water and fish, causing severe damage to the lungs, kidneys, and intestines and even causing death. In this paper, a jute nose holder mask was prepared as an alternative to typical masks to reduce plastic pollution. The jute nose holder was produced with a modified jute flyer-spinning frame machine, where jute was used as the sheath and metal wire was applied as the core component. The nose holder was later coated with starch-based natural gum. Then, the non-woven fabric of 75 grams per square meter (GSM), and the jute nose holder were used to produce the alternative, environmentally friendly mask, which might reduce the 773 tons of plastic waste generated daily from the nose holder of the mask. This alternative mask was then distributed to 900 people for a survey to find out their opinion. From the results of the survey, it is seen that 82.6% of people felt no problem in the nose when they put on the given mask. 85.6% considered the mask more comfortable than the traditional mask, and it was rated above average by 79.8% of the surveyors. So, this study suggests that the given mask can be a sustainable alternative to traditional masks.

摘要

各种形式的塑料总是会对环境、人类和其他生物造成危害。新冠疫情使塑料制品的使用比以往任何时候都更加严重,其中外科口罩对塑料污染的贡献最大。这些口罩散布到陆地和水生环境中,在那里它们会分解成更有害的微塑料。这些微塑料通过水和鱼类进入人类食物链,对肺部、肾脏和肠道造成严重损害,甚至导致死亡。在本文中,制备了一种黄麻鼻夹口罩作为传统口罩的替代品,以减少塑料污染。黄麻鼻夹是用改良的黄麻翼锭细纱机生产的,其中黄麻用作外皮,金属丝用作核心部件。鼻夹随后涂上淀粉基天然胶。然后,使用每平方米75克(GSM)的无纺布和黄麻鼻夹制作出这种环保型替代口罩,这可能会减少口罩鼻夹每天产生的773吨塑料垃圾。然后将这种替代口罩分发给900人进行调查,以了解他们的看法。从调查结果可以看出,82.6%的人戴上给定的口罩时鼻子没有问题。85.6%的人认为这种口罩比传统口罩更舒适,79.8%的受访者对其评价高于平均水平。所以,这项研究表明给定的这种口罩可以成为传统口罩的可持续替代品。
