Abstract
Textile materials made of or containing wool or other animal fibre are treated with a dilute aqueous solution of a permanganate at a temperature not above 60 DEG C. and a pH between 5 and 10, this treatment being preceded or followed by treatment with a solution containing 0.5-10 per cent by weight of a sulphur-containing reducing agent at a pH between 5 and 10.5. The tendency of the materials to shrink when washed is thus reduced. The permanganate may be an alkali or alkaline-earth permanganate and the reducing agent may be a sulphite, bisulphite, metabisulphite or hydrosulphite of an alkali metal, calcium, magnesium or ammonium. The permanganate solution may be buffered by addition of zinc sulphate. The materials treated may be loose wool, slubbing, yarn, fabrics or garments, in the oil or scoured state, and the animal fibre may be mixed with cellulosic fibres such as cotton or rayon, or rubberised threads. The treatment may be applied before or after dyeing. In an example, wool yarn is treated at atmospheric temperature with a dilute solution of potassium permanganate containing zinc sulphate and a wetting agent, e.g. a sulphonated fatty alcohol or an ethylene-oxide condensation product, and the material is then drained and treated with a 2 per cent solution of sodium bisulphite at 40 DEG C. Specification 569,730 is referred to.
