The pH values were recorded with Hanna pH meter and
The cationised cotton fabric samples were cut into pieces
approximately 1 cm2 and dyed at pH 2.5 in a beaker with
160 ml aqueous solution composed of 1 g/l non-ionic wetting
agent (Hostapal CV, Clariant) and 8 g/l lac dye with liquor ratio
40:1 at 80 _C with frequent shaking.
