A specimen of the textile (textiles of all kinds and in all forms) is exposed to the action of gaseous formaldehyde in a closed container. The change in colour of the specimen is assessed with the grey scale. This method is not suitable for assessing changes in colour which may occur during crease-resist finishing with urea-formaldehyde products, or in subsequent treatment of the dyeing with solutions of formaldehyde.
