Dyeing Studies of Cotton Towel Product with Natural Dyes and Effect of Cationization on Colour Characteristics

摘要

This research was focused upon and concerned with the resulting effects of dye extraction from using the following natural products: Lac, purple corn cob, golden shower tree seed pods, garcinia dulcis bark and dried mangosteen leaves. After applying them to cotton towel products, from their natural dyeing ability using the exhaustion process. The cotton towel was pretreated using a cationizing agent (Starcat PD) before dyeing. The cotton towel was then dyed in the solution extracted from the lac, resulting in forming a pink shade as a result. The sample dyed with purple corn cob and golden shower tree seed pods resulted in violet-brown colour and dark brown shades, in varying results respectively. Using the garcinia dulcis bark and dried mangosteen leaves, the colour shade varied beteen a yellow and brownish orange. The results showed that the dyes K/S values of the treated cotton towel were improved, compared with those of the un-treated one.
