“…In the present investigation poly(vinylamine chloride) (PVAmHCl; 1) has been investigated as a physical modifying agent. Thanks to its wide range of properties PVAmHCl has found use in catalysis, chelation, liquid chromatography, treatment of wastewater, recovery of oil [12], and in polymeric dyes [13]. It has been used in applications as diverse as paper making and biomedical research, but its use for the modifi cation of cotton for saltfree dyeing has not previously been reported.…”

Poly(vinylamine chloride) has been investigated as a pretreatment for the salt‐free dyeing of cotton with reactive dyes. Dye fixation was found to be much higher than by conventional dyeing without pretreatment, even in the presence of a large amount of salt. The influence of pretreatment conditions on dye fixation, such as pad–bake variables and the concentration of poly(vinylamine chloride), has been studied. The dyeing behaviour of CI Reactive Red 2 on pretreated cotton was examined and found to follow a Langmuir‐type adsorption curve. Dyed cotton pretreated with poly(vinylamine chloride) showed excellent wash fastness and good rub fastness. It is concluded that poly(vinylamine chloride) is effective as a pretreatment for salt‐free dyeing with reactive dyes.

Polymers and Dyes: Developments and Applications

Amongst functional macromolecules, the combination of polymers and dyes is a research field of great potential with regard to high-performance materials. Accordingly, colored polymers have become increasingly important as materials for miscellaneous technical applications in recent years while also being a major part of everyday life. For instance, dye-containing polymers are nowadays widely applied in medicine, painting industries, analytics and gas separation processes. Since these applications are obviously connected to the dye's nature, which is incorporated into the corresponding polymers, the affinity of certain polymers to dyes is exploited in wastewater work-ups after (textile) dyeing procedures. In this review, we wish to point out the great importance of dye-containing polymers, with a comprehensive scope and a focus on azo, triphenylmethane, indigoid, perylene and anthraquinone dyes. Since a large number of synthetic approaches towards the preparation of such materials can be found in the literature, an elaborated overview of different preparation techniques is given as well.

“…In polymeric dyes, chromophores are introduced either by the monomer or the polymer. Dawson et al prepared water-soluble polymeric dyes by attaching water-insoluble anthraquinone chromophores to the copolymer of N-vinyl acetamide and sodium vinyl sulfonate (Dawson et al, 1978). The synthesis of water-soluble polyamide polymeric dyes from 4 monomers having anthraquinone chromophore groups (1,5-bis(2-hydroxyethylamino)anthraquinone and 1,5-bis(2-hydroxyethoxy)anthraquinone) by condensation polymerization have been reported (Meng et al, 2002).…”
