ABSTRACT:
In a process for the treatment of woollen textile material, which may be in the form of yarn or fabric, to reduce shrinkage and felting and improve resistance to abrasion, by depositing a polyamide-epichlorhydrin resin thereon, the material is given a subsequent treatment with an aqueous polyurethane dispersion. The polyurethane thus disposed adds to the improvement in properties brought about by the polyamide-epichlorhydrin resin. The woollen textile material to the treated, especially when in the form of yarn, may comprise wool admixed with other (particularly synthetic) fibre, such as fibres of viscose, polyesters and especially polyamides, such as nylon.
