Abstract

A method of treating wool and/or other natural fibres with a chemical compound, the compound undergoing photoyellowing at a similar rate to the rate at which the wool and/or natural fibres undergoes photobleaching. The chemical compound is applied in an amount which ensures the photoyellowing of the chemical compound cancels out the photobleaching of the natural fibres. The chemical compounds are preferably syntans and may consist of condensation products of aromatic sulphonic and/or sulphonic acids. Other suitable compounds include optical brightening agents, tannins, and aromatic sulphonic acids.
