Printing wth Disperse Dyes on Man-Made Fibers

Practically all synthetic fibers can be printed with disperse dyes. Cationic dyes are used preferentially for acrylic fibers, and acid dyes and metal-complex dyes can be used for prints on polyamide fibers. The importance of printing with disperse dyes and the relative amount of different man-made fibers used for prints varies according to fashion and local requirements. Polyester fabrics alone or in combination with cotton are the most important. After precleaning, fabrics made from synthetic fibers must be heat-set to achieve dimensional stability and crease resistance. The usual setting conditions are 20-30 s at 190-210°C, and for texturized articles about 30°C lower. [Pg.401]

In addition to the normal direct printing process disperse dyes can be applied by the so-called transfer printing technique, in which disperse dyes are first printed on paper and then transferred to the textile by sublimation. With suitable dyes discharge and resist printing are also possible. See also [139], [Pg.402]

Standard fixation conditions for disperse dyes on polyester fibers [Pg.402]

Blends of polyesterand cellulosic fibers are printed with disperse and reactive dyes only in cases, when pigment printing is unsatisfactory. Dye selection follows basically the rules given for continuous dyeing polyester and cellulose fibers. [Pg.402]
