| abstract |
A method of treating fibers of animal origin (wool from sheep, cashmere, rabbit, mohair, llama, goat, camel, among others), characterised in that it consists of bringing the fiber into contact with a solution of modified proteases, bonded or not to other substances, in order to increase its molecular weight and reduce its diffusion inside the fiber. It is intended that the cuticle of the fiber be the only accessible part to the protease attack, thus allowing an increase in the resistance to shrinkage and anti-felt finishing, in comparison with untreated material. |
