stick from cotton tree with cotton balls

Cotton, wool – it’s all the same, right? Not really. Anyone who has ever accidentally put a wool sweater in the regular wash knows that's not a good thing. Wool cannot withstand high temperatures – it shrinks quickly and felts. Cotton is harvested from the cotton bush and then processed into T-shirts, for example, whereas wool is of animal origin. One should make sure to separate these textiles when washing. This experiment shows yet another difference between wool and cotton.
