Purpose – This study aims to improve the natural dyeing recipe with better light fastness using ascorbic
acid (vitamin C) with pulverised plant dyes.
Design/methodology/approach – Silk fabrics pre-mordanted with alum (aluminium ammonium
sulphate) were dyed using six types of plant dyes available in Sarawak, Malaysia, namely, Engkerabai
leaves (Psychotria viridiflora), Ketapang leaves (Terminalia catappa), mangrove bark (Ceriops tagal), Sepang
wood (Caesalpinia sappan), mangosteen husk (Garcinia mangostana) and onion skin (Allium cepa). Then, the
dyed samples were immersed in vitamin C. The dyed and vitamin C-treated silk samples were exposed to direct
sunlight for 40 h to test whether vitamin C had any effect on the light fastness of the dyed samples.
Findings – It was found that the fabric samples using vitamin C for after-treatment, particularly
Engkerabai, Ketapang, mangrove and mangosteen, exhibited better light fastness. The colours of the four
samples changed and looked darker when compared to the non-treated fabric samples. However, it was
observed that vitamin C had a reverse effect on Sepang wood and onion skin. The acidic aqueous solution of
vitamin C discharged the dyed samples instead.
Originality/value – In conclusion, depending on the plant types, vitamin C can be used to improve the
light fastness of natural dyes or as a reducing agent for natural dyes. |
