Abstract
The visual appearance of pigmented or dyed 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 abraded fibrils attached to the aramid filaments in the fabric. Use of a conventional washing machine is suitable in the fabric contact with the dye.
