Why do cotton clothes sometimes shrink when washed?please answer it as fast as possible to me
"There are two kinds of shrinkage. Progressive shrinkage occurs when
the fiber itself shrinks. Wool fiber shrinks a little more each time
it is washed, which is why wool is usually dry cleaned. Relaxation
shrinkage is when the fabric shrinks. It is caused by the tension
applied to yarns and fabrics during construction. The tension is
released when the fabric is washed or steam pressed, causing it to
shrink to its natural size. Most cotton fabric shrinkage occurs during
the first wash."
