Abstract
A method of treating wool, wool fibers or animal hair with a proteolytic enzyme and a transglutaminase. The described method results in improved shrink-resistance, handle, appearance, wettability, reduction of felting tendency, increased whiteness, reduction of pilling, improved softness, tensile strength retention, improved stretch, improved burst strength, and improved dyeing characteristics such as dye uptake and dye washfastness. Furthermore, relative to treatments with proteolytic enzymes alone (no transglutaminase), the described method results in reduced weight loss, reduced fiber damage, and improved strength.
