Why cotton and wool hold water differently
Cotton drinks liquid water into the fiber, while wool can bind vapor and still shed a light wetting.
When the purchase is complete, return to the original window. It will refresh.
From the opening
Cotton and wool both take up water, and they put it in different places. Cotton's cellulose pulls liquid water into the fiber and holds it against you, while wool's keratin can bind water vapor inside the fiber while the scaly surface is slower to let liquid soak through. The opening covers cotton wicks liquid into cellulose, wool binds vapor inside the fiber, and scales and crimp delay a soaking.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
