    摘要： Improvement of a process for spin-dyeing acid-modified polymers or copolymers of acrylonitrile in which cationic quaternary dyestuffs are added to the spinning mass and spun according to the wet-spinning procedure. The improvement is characterized by using dyestuffs characterized by a migration factor M of 20 or less than 20, by a combination index K of less than 2.5 and a cation weight of more than 310. Migration factor M and combination index K are known values in the dyestuff field or can be determined. The dyestuff to be used according to the invention can belong to the most different classes of dyestuffs; they fix rapidly on the polymer, and thus they do not color, or color only to a minor extent, the coagulation, stretching and washing baths although they are soluble in water and aqueous solutions of these baths. The fibers and filaments obtained by the process of the invention have outstanding fastnesses to wet processing and, owing to the absence of dyestuff aggregates at the surface of the fiber such as occur when spin-dyeing with pigments, very good fastnesses to dry and wet rubbing. The fibers are intense, absolutely transparent and free from specks.

    摘要： A dyeing process has been found which enables to dye uniformly polyacrylonitrile fiber materials, by using as dyestuffs basic azo dyestuffs being non-quarternized and containing neither cationic quaternary ammonium groups nor cationic N-substituted or N-unsubstituted iminium groups, said azo dyestuffs containing on the other hand at least one unsubstituted or substituted amino group, hydrazino group, amidino group or guanidino group capable of forming salts. The very dyeing process as such is carried out according to usual processing data for dyeing polyacrylonitriles in a slightly acid medium. Especially with the use of several of these dyestuffs for polychromic dyeing, such as trichromic dyeing, special advantages are obtained, insofar that even at cut-rate dyeing periods and for preparing light color shades, there are obtained even dyes with constant color shades, when using these dyestuffs having good migrating properties.
