“…3, it was believed that with the decrease of crystal area, the penetration of droplets into the ber amorphous area increased after the droplets impacted on the fabric surface, which accelerated the penetration of droplets perpendicular to the fabric surface. That also meant that the increase of amorphous area, the combination of cotton fabric and dye ink increased, leading to the improvement of dye utilization (Xie et al 2020).…”

Cotton fibers have a high crystallinity, which makes a large number of reactive hydroxyl groups blocked and therefore affects the ink-jet printing performance of reactive dyes on cotton fabrics. In this work, the alkali treatment was employed to adjust the structure of cotton fibers. The crystallinity of treated cotton fibers reduced from 73.9–58.5%, and the breaking strength did not decrease compared with original cotton fiber. Thus, the accessible reactive hydroxyl groups and the wettability were enhanced for treated cotton fibers, which promoted the penetration of inks into the fibers. The optimal K/S value of 23.47 was achieved for treated cotton fabrics which was higher than that of untreated cotton fabrics (17.15). Meanwhile, the printed fabrics displayed good washing fastness, rubbing fastness and glossiness. This work provides an effective way for improving the utilization of dye solution and producing high-quality cotton fabric digital printing products.

“…Therefore, it is necessary to investigate the aggregation state of dye molecules in concentrated solutions. Water-soluble polymers [17][18][19] and additional organic solvents, such as lactam compounds, ethylene glycol can obtain better inkjet printing effects [20][21][22][23] because these are mainly used to reduce the formation of satellite droplets at high concentrations. The aggregation behavior is also affected by salts, particularly, by the metal ion salts in solutions.…”

“…However, the usage of chemicals and salts causes additional pressure on the treatment of the coloration effluent, making it difficult to meet environmental requirements. 10,11 Therefore, the development of new technologies for cotton coloration with low dye consumption and low chemical usage, such as digital inkjet printing, has been a hot spot for researchers to work on in the past decades. 12,13 Digital inkjet printing has been considered as a revolutionary technology in comparison with conventional screen printing, exhibiting a variety of characteristics and advantages, such as noncontact printing, no printing screen, outstanding image resolution, creative images, flexible production, low usage of electrolytes, etc.…”

Digital inkjet printing of textiles possesses great advantages like high efficiency and flexible production, but the challenges like the risk of causing serious environmental problems due to the large usage of dyes and chemicals still remain a matter of concern. In response to this problem, herein, a novel kind of reactive dye@copolymer nanosphere was prepared through the adsorption of C. I. Reactive Red 218 dyes (RR218) onto cationic poly(styrene-butyl acrylate-vinylbenzyl trimethylammonium chloride) (PSBV) nanospheres and applied in inkjet printing on woven cotton fabric. Results show that the prepared RR218@PSBV nanospheres possessed homogeneous size and good stability for ink preparation. In comparison with the original RR218 solution, the color depth of RR218@PSBV-printed fabric increased by 1.4 times and the dye residues in the printing effluent were reduced by about 45%. Meanwhile, the consumptions of sodium carbonate and urea in conventional inkjet printing were reduced by about 3.3 and 22.8 mg/cm 2 , respectively, and the printing process was simplified with 30% energy saving. Furthermore, the mechanism of the color enhancement by nanospheres was revealed by the calculation of absorption and scattering coefficients based on the Kubelka−Munk function. This work provides a potential application of dye@polymer nanospheres to promote the optimization of the textile inkjet printing technique and alleviates the environmental impact of conventional textile coloration.
