It's strange to me that some clothing fabrics distinctly change color when I wipe my wet hands on them, while others do not. For instance, I can wipe wet hands on bluejeans and it's completely unnoticable, whereas if I wipe water onto a cotton shirt it makes the shirt look wet. Both the jeans and the shirt are cotton, but they take water differently. There seem to be several factors that affect how clothing looks after being wiped with water:
- Material -- cotton, silk, polyester, etc.
- Texture -- weave(?), thickness, roughness
Are there some unifying characteristics involved that I'm not noticing?
