Abstract (en)

[origin: EP0358386A2] A method for the treatment of wool so as to impart shrink resistance comprising, in any order, the steps of:- i) treating the wool with a proteolytic enzyme, and ii) subjecting the wool to either or both of an oxidative treatment and treatment with a polymer, with the proviso that when the oxidative treatment is used alone it comprises a wet chlorination process. The method may be operated either as essentially a batch process or as a process involving a combination of continuous and batch treatments.
