Physico-chemical studies of disazo dyes derived from paminophenol On synthetic polymer-fibres
Abstract
The physico-chemical properties of a series of disazo dyes derived from p-aminophenol on polyester and
nylon 6 substrates are described. It was found that the dyes generally have higher affinities for the polyester fibre than
for the nylon 6 fibre. The values of Δμo, ΔHo and ΔSo in the two dye-fibre systems suggest that the hydrogen bonding
mechanism is operative in the dye-fibre binding forces
