Abstract

The dye penetration coefficients, the starting temperatures of contraction and other factors in the carrier dyeing of poly(ethylene terephthalate)fibre, were determined as a function of carrier concentration in the dyeing bath.The dependence of dye penetration coefficient on the concentration of carrier and the temperature was found to be shown formally by the Williams-Landel-Ferry equation, Here p and p, are the dye penetration coefficient at absolute temperature, T and that at temperature, Ts, respectively. The subscripts, (c) and (0) indicate the concentration of carrier added and that of zero, respectively. In the above equation, T8, (0) and Ts, (e) are the temperatures which are higher by 25°C than the starting temperature of contraction in each dyeing bath.
