When washing wool, silk or other delicate materials, you need an extra gentle detergent, where the active ingredients are surfactants, not enzymes. Enzymes are particularly made to break down and dissolve dirt consisting of protein (organic stains, food, sweat, make-up etc.).
Wool and silk are natural materials and consist of nothing but protein. So, when washing with enzymes you will, in just a couple of washes, break down the structure of the garment.
