“…Second, the dye is covalently fixed onto the cotton fiber by use of alkali (sodium carbonate) [98,99]. For improving the dyeing performance of reactive dyes on cotton, the fibers can be pre-treated with amino-group-bearing dendrimers like AstramolTM [100]. Technically, the dye is then attached to the dendrimer, which allows enhanced dyeing efficiency and color strength since primary amino groups are easier to activate than the hydroxyl-groups in the cotton fiber.…”

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.

ABSTRACT:A commercial serine-type protease preparation (Alcalase) was examined as a scouring agent for cotton fabrics. Application of the enzyme induced moderate changes in the composition of fibers that were mainly associated with the removal of protein and waxes. The relationship between the compositional modifications and structural transformations, which were reflected in the crystallinity index of the bioscoured cotton fibers, was demonstrated. The protease-treated textiles displayed superior whiteness and outstanding compressional resilience but exhibited a poor hydrophilicity and dyeing capacity. One-step scouring at neutral conditions, where proteolytic activity was supported by multienzyme combinations, could generate textiles with sufficient water absorbency and advanced performance. The implementation of the appropriate scouring conditions (concentration and combination of enzymes) could form fabrics with the desired physicochemical and micromechanical properties.

“…The major attempts on reduction or elimination of salt can be summarized under three categories; reduction of liquor ratio during the dyeing process, modification of dyes such as usage of low salt or polyfunctional dyes like Cibacron LS, Novacron LS, Teegafix HE reactive dyes (Cai, Pailthorpe, & David, 1999;Farrell, 2012;Paluszkiewicz, Matyjas, & Blus, 2002;Singha, Maity, & Singha, 2013;Taylor, 2000) and modification of cotton using chemicals, compounds, enzymes, nanoparticles, ultrasonic waves, plasma, gamma, ozone treatments (Burkinshaw, Mignanelli, Froehling, & Bide, 2000;Gashti, Pournaserani, & Ehsani, 2013;Gulzar et al, 2013;Hao et al, 2015;Kamel, Zawahry, Ahmed, & Abdelghaffar, 2011;Parvinzadeh et al, 2010;Patiño et al, 2011;Zhang, Ju, Zhang, Ma, & Yang, 2007).…”
