Abstract:
Nowadays, there is trend toward selecting products that are made using natural
resources. The demand and acceptance for natural products is on the rise. Therefore
various industries including textile dying industry focus on natural products. In the
present study, the aim is on tobacco to be used as a natural dye source. In this study
nicotine (NCT) is extracted from leaves of tobacco using 0.01M HCl. The NTC extract
was used on cotton fabrics. This study tested two NTC extracts based dying conditions.
First, cotton was oxidized using oxidizints agents (H2O2, NaOCl and KMnO4) at pH 7
without using a mordant. thereafter oxidized cotton was dyed using NTC extract. In the
second test NTC extracts was used to dye cotton with mordants ((NH4)AI(SO4)2, FeSO4
and CuSO4 ) at pH 9. In addition anti-bacterial efficacy of NTC extract and NTC dyed
cotton were tested. According to the results, NTC extracts with different mordents gave
respective shades on cotton. Oxidized cotton once dyed with NTC extract also produced
shades of color. Appearance of fabric was observed to determine shades of color; NTC
extracts on cotton gave yellow and dark brown shades in general. The fabric treated with
mordant FeSO4 and the fabric oxidized with KMnO4 appeared dark brownish to black.
Also. there is no significant antibacterial efficacy result produced by NTC extracts when
taken alone as a dye or when taken as a dye fixed on cotton fabric.
