Treatment of leather or animal skins with a transglutaminase (TG), preferably together with a glutamine and/or lysine containing polymer or oligomer, such as keratin or casein, has a beneficial effect on the subsequent dyeing and colour properties of leather. The uptake of protein or enzyme is improved when the hide or leather is dried prior to treatment with a solution of protein or enzyme. Transglutaminase treatment is also shown to improve resistance to abrasion and collagenase. |
