UTILIZATION OF AQUEOUS, METHANOL AND CHLOROFORM EXTRACTS OF LOCAL PLANTS- IXORA COCCINEA AND HIBISCUS SABDARRIFFA (ZOBO) FROM ABAKALIKI AS FABRIC DYES

Abstract

This investigation dealt with the dyeing and fastness properties of crude constituents of Ixora coccinea and Hibiscus sabdarriffa plant species extracted using distilled water, methanol and chloroform. Approximately 150 g of each sample was soaked in the chosen solvent for four weeks, the percentage yields of the aqueous, methanol and chloroform extracts of Ixora coccinea were 38.47% and 13.40 % and 3.88 % respectively; Hibiscus sabdariffa gave yields of 22.85 %  for the aqueous extract, 12.24 % for the methanol extract and 3.79 % for the chloroform extract. Aqueous, methanol and chloroform extracts of Ixora coccinea were all pink in colour; Hibiscus sabdariffa gave red aqueous extract, red methanol extract and orange chloroform extract. The extracts were used without further purification in dyeing unmordanted and mordanted cotton and polyester fabrics. Different colour shades were obtained after dyeing. The mordanted fabrics using CuSO₄, FeSO₄ and K₂CrO₇ were fast to acid, alkali and washing.
