What fabric should I buy for the eye mask?

Soft silk eye mask

Sleep goggles are made of cotton, silk, polyester and memory cotton. Their advantages and disadvantages are shown in the following figure:

It can be seen that the eye mask made of polyester has poor air permeability and is not suitable for long-term use, while the eye mask made of pure cotton will harden after repeated washing, and it will be uncomfortable to wear for a long time. Therefore, the most suitable materials are generally silk and memory cotton goggles, which are durable and comfortable.
