Abstract

Wool is treated with chlorine and then with a preformed synthetic polymer which is either water-soluble or able to form an aqueous dispersion to reduce its felting shrinkage. The chlorine may be derived from an aqueous solution of a hypochlorite and an acid or gaseous chlorine may be used. 0.1-0.5% by weight of chlorine may be reacted with the wool. Suitable synthetic polymers are polyethylene imine, polyamide-epichlorhydrin resins, polyethylene and other polyolefines and polyacrylates. When polyacrylates are used the curing of the polymer may be catalysed by the use of ammonium chloride, oxalic acid, magnesium chloride, sulphuric acid or zinc nitrate. The chlorine treatment and polymer application need not necessarily be carried out as successive operations, the chlorination pretreatment under acid conditions being carried out on loose wool and the polymer later being sprayed on to the loose wool or when the wool had been woven or knitted up into a fabric, as an aqueous solution or dispersion. After impregnation with the polymer solution or dispersion the woollen material may be dried and then steamed in a semi-decatiser for 1-5 minutes to effect curing or passed through metal rollers heated to 150 DEG -400 DEG C. After the chlorination the material may be treated with sodium sulphite prior to the treatment with the polymer.
