A continuous dyeing technique is described in which fabrics of secondary cellulose acetate, cellulose triacetate, and Terylene are padded with disperse dyes and, after being dried, are subsequently immersed in the saturated vapour of trichloroethylene for times up to 60 sec. to fix the dyes on the fibres. The exhaustion and the fastness properties of dyes fixed by this means on secondary cellulose acetate and cellulose triacetate fibres are at least equal to those obtained by conventional dyeing methods; dyeings on Terylene are limited to pale and medium depths on filament fabrics. The construction and the operation of a continuous plant handling 12‐in. wide fabrics at speeds up to 10 yd./min. are described. The process is suitable, without modification, for dyeing blends of these fibres with viscose rayon and cotton, making use of reactive dyes for the cellulosic component.
