Abstract Results on surface conductivity of cotton fibres dyed with reactive dyes have been reported. In general the surface conductivity values were higher in alkaline pH, but lower in acidic pH as compared to the neutral pH. This observation has been attributed to the contribution of the functional groups present on the dye molecule reacted with the fibre. Results on the surface conductivity of fibres dyed with mono- and bifunctional reactive dyes suggest that dyes react with the hydroxyl groups of the fibre, and that the bifunctional dye molecule forms a crosslink between two cellulosic chains.
