Prepare a comparative chart of different types of fabrics such as-
(a)100% cotton (b) Polyester (c) Silk (d)Linen
The criteria of comparison between the fabrics should include the following factors:-
i) Its ability to capture semi-micron particles.
ii) Its ability to breathe through it.
iii) The effectiveness of masks after wearing it for 3 hours.
Answer:Because N95 and surgical masks are scarce, it is best to sue face mask made from fabric. Compared to most fabric polyester is considered more effective
Explanation:A “good homemade mask” uses a dense material which traps “viral particles” but is breathable enough to withstand them.
Polyester is a washable, comfortable, & tightly knitted fabric. This type of fabric wipes out your breath’s moisture and also enables you to breathe freely
Polyester fabric filters nearly 80-99 per cent of the particles depending on their size.
