Extraction of natural dyes from Daucus carota Linn. (carrot)
plant was carried out through boiling and solvent extraction
process. The materials were cut into small pieces and soaked in
water, methanol or acidified methanol. In the case of boiling
method, the materials were cut into small pieces, soaked in
distilled water and heated for 1hour at 100°C. However, for
solvent extraction method, the materials were cut into small
pieces and soaked in methanol or acidified methanol and placed
in dark room for two days at room temperature. The solution
was then filtered and mixed with 2% of selected mordant based
on weight fabric (o.w.f.). The dye liquor was used to dye silk
fabric at 80°C for 1 hour. Soap at boil was carried out to remove
unattached dyes for 5 minutes. The dyed fabrics were also
analysed in terms of colour fastness to washing using several
standard methods.
