Zusammenfassung:The present invention relates to a process for improving the natural appearance of an article of clothing, which comprises a yarn of para-aramid fiber. The process involves contacting undyed and non-pigmented yarn with an aqueous dye solution or dye dispersion wherein the process is particularly adaptable using a conventional washing machine. 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.
