Why polyester dries fast
Polyester holds almost no water inside the fiber, so liquid stays on the surface and leaves quickly.
When the purchase is complete, return to the original window. It will refresh.
From the opening
Polyester dries fast because the fiber is a plastic that takes up very little water. Liquid stays mostly on the outside of the filament and in the gaps between fibers, where air can evaporate it, instead of binding inside the material. The opening covers the filament itself stays almost dry, surface water evaporates first, and pile can trap water anyway.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
