Method of treating fabric

摘要

A method of treating fabric comprising dyed cellulosic fibres to increase its photostability comprises applying to the fabric a substance which is absorbed into and/or coated on to the fibres such that the diffusion of atmospheric oxygen into and/or within the fibres is inhibited. The method may be carried out as part of a laundering process or an industrial textile treatment. The method is particurlarly effective when the compound is used in conjuction with a sunscreen such as a benzotriazole.
