Uniformly dyed water-swellable cellulosic fibers

Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula in which one R is R1, OR1, SR1 or the other R is R1 and R2 independently of one another are hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical,...

Zusammenfassung:Uniformly dyed water-swellable cellulosic fibers obtained by dyeing cellulosic fibers in the swollen state with a dye of the formula in which one R is R1, OR1, SR1 or the other R is R1 and R2 independently of one another are hydrogen or an aliphatic, cycloaliphatic, araliphatic or aromatic radical, may also be a saturated heterocyclic radical, and D is the radical of a diazo component. The dyed fibers exhibit very good fastness properties.
