Method to shrinkproof wool by plasma polymerization

摘要

A method of treating wool in the form of a fibre, yarn, sliver, fabric or garment. A polymer coating is applied by plasma polymerisation to prevent shrinkage due to felting due to laundering. The method may include a pre-treatment step, for example application of a continuous plasma of inert gas, application of nano particles to the fibre surface or coating the fibre surface with a polymer.
