“…Non-aqueous dyeing is a green and environmentally friendly dyeing technology which uses non-polar media to substitute for water [11,12]. Moreover, Yang [9] and Fu [13] believe that non-aqueous dyeing has been the most successful attempted substitute for traditional water-based dyeing in the textile industry. Non-aqueous dyeing media cannot dissolve water-soluble dye but can transport material and transfer energy.…”

In recent years, new concepts in textile dyeing technology have been investigated which aim to decrease the use of chemicals and the emission of water. In this work, dyeing of cotton textiles with reactive dyes has been investigated in a silicone non-aqueous dyeing system. Compared with conventional aqueous dyeing, almost 100% of reactive dyes can be adsorbed on cotton textiles without using any salts in non-aqueous dyeing systems, and the fixation of dye is also higher (80%~90% for non-aqueous dyeing vs. 40%~50% for traditional dyeing). The pseudo-second-order kinetic model can best describe the adsorption and equilibrium of reactive dyes in the non-aqueous dyeing systems as well as in the traditional water dyeing system. In the non-aqueous dyeing systems, the adsorption equilibrium of reactive dyes can be reached quickly. Particularly in the siloxane non-aqueous dyeing system, the adsorption equilibrium time of reactive dye is only 5–10 min at 25 °C, whereas more time is needed at 60 °C in the water dyeing system. The surface tension of non-aqueous media influences the adsorption rate of dye. The lower the surface tension, the faster the adsorption rate of reactive dye, and the higher the final uptake of dye. As a result, non-aqueous dyeing technology provides an innovative approach to increase dye uptake under a low dyeing temperature, in addition to making large water savings.

“…Pigment printed fabric display great color, clear outline and full of three‐dimensional sense, but the shortcomings of pigment printing also exist, the biggest of which is the rough feel to handle. A large number of adhesives are required in the pigment printing industry to solve the problem of low color fastness, which was caused by the poor attraction between pigments and fabrics 18–20 . At present, conventional polymeric dispersants are usually used only for pigment dispersion and stability.…”

“…Thus, the fabrication of efficient, self‐adhesive dispersant becomes the hotspot in this field. Many efforts have been made to endow dispersant with self‐adhesive through molecular structure design 19 . Among those methods, branching is a suitable structure to obtain self‐adhesive dispersant 21,22 …”

A series of reactive branched polyurethane dispersants (BPUs) were successfully synthesized based on epoxy as reactive group and nitrogen-containing heterocycles as anchoring group. The branched polyurethane was adopted an ''A 2 + B 3 '' approach with diisocyanate prepolymer and trimethylolpropane. The structure, molecular weight, and thermodynamic property of BPUs were characterized. The pigment dispersions were prepared with BPUs as the dispersant by ball milling, and then the characteristic parameters such as pigment particle size, viscosity, stability, color properties, and fastness were evaluated.Excellent dispersing performances were observed that the particle size of five dispersions were below 200 nm, with the viscosity as low as 6-9 mPaÁs. It is worth noting that the pigment dispersion prepared by BPU exhibited excellent stability and self-adhesive performance. These dispersions were printed on cotton fabrics without adhesives, their water washing fastness was approximately grade 4. And the dry rubbing and wet rubbing fastnesses were 3 and 2-3, respectively.

“…In recent years, the development of functional finishing agents with chemical reactivity to cotton fabrics has been necessary to improve durability and functional properties. A polymer with a vinyl sulphone group was prepared, one which had adequate dispersibility to CB pigment and that could also fix CB pigment onto cotton cellulose through covalent bonding 17 . Reactive multiwalled carbon nanotubes (MWCNTs) were prepared with triazines as reactive functional groups, which have high reactivity to cotton fabrics, subsequently improving the water fastness of the prepared functional textiles 18 …”

Functional polymer modified carbon black (CB) pigment (P-(DMC-co-CHPMA)g-MPTS/CB) with reactive epoxy and quaternary ammonium groups was designed and prepared via a thiol-ene click chemistry reaction, and its dispersion ability in the aqueous phase, as well as its colouring and anti-bacterial properties for cotton fabrics, were investigated. In considering both dispersion ability and reactive ability to cotton fabric, the mole ratio of the monomers (methacrylatoethyl trimethyl ammonium chloride [DMC] and 3-chloro-2-hydroxypropyl methacrylate [CHPMA]) was discussed. Morphology and chemical properties of P-(DMC-co-CHPMA)-g-MPTS/ CB were tested by scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis and X-ray photoelectron spectroscopy, resulting in a weight content of copolymer (DMC-co-CHPMA) in P-(DMC-co-CHPMA)-g-MPTS/CB of ca. 18%. P-(DMC-co-CHPMA)-g-MPTS/CB was fixed onto cotton fabric via a nucleophilic-substituted reaction between reactive epoxy groups on the CB surface and the hydroxyl groups of cotton fabric, which endowed good fastness to cotton fabric without either a fixing or an adhesive agent. Also, coloured cotton fabric demonstrated excellent anti-bacterial activity towards Staphylococcus aureus
