The visual appearance of undyed or unpigmented para-aramid fabric generally present in an article of clothing is restored by contacting the fabric with an aqueous dye solution or dispersion to dye the aramid fibrils present on the yarns. Use of a conventional washing machine is suitable in the fabric contact with the dye.
