Data are presented concerning the rate of dyeing of cellulose triacetate loose staple fibre with 3% Duranol Red X3B 300 (C.I. Disperse Red 11, C.I. 62015) from aqueous solutions of η‐butanol or benzyl alcohol. In water saturated with η‐butahol, more than 85% exhaustion is reached after 1 hr. at 80d̀c., 30 min. at 60d̀c., or 1 hr. at 40d̀c. After 30 min. in water saturated with benzyl alcohol, 68% of the dye present is fixed on the fibre at 40d̀c., 78% at 60d̀c., and 80% at 80d̀c. In general, with either solvent, the highest amount of dye fixation is obtained at about 60d̀c. At higher temperatures less solvent is needed and the time of dyeing can be reduced. A method for dyeing Tricel (BrC) or Terylene (ICI) in fabric form is suggested.
