Basella rubra Linn : A Dyeing study for Silk

ABSTRACT In the present study basella rubra berries of India origin was extracted for dyeing of silk as a natural dye. Extraction was carried out with two different methods. In method I, extraction was carried out at room temp. in cold tap water. In method II, extraction was carried out at boiling temp. pH of the colour extract was scanned and noted 6.5 as acidic pH. Citric acid treatment was given to samples of experimental group prior to dyeing. Samples of control and experimental group were dyed with both cold and hot dyeing method. 10% alum and alum in combination with other mordants imparted range of mauve, beige, pink and gold. Dyed silk samples exhibited moderate to very good wash and sunlight fastness. Citric acid treatment showed improved fastness properties. REFERENCES Nadkarni KM 1976, Indian Material Media.
