I have heard that cotton FABRIC shrink when washed, but do the cotton FIBER 
itself shrink?
 Another thing is that from this website:

It says that cotton has excellent resistance to sunlight. However, as far as I 
know, prolonged exposure of sunlight will weaken the cotton fabric. So how can 
cotton have "excellent sunlight resistance"? I think it should be "moderate" 
or could I be wrong?
