“…From the self-assembled photonic crystal structures and corresponding structural colors of reactive dyes/PSt microspheres with different particle sizes on mulberry silk fabrics, it can be concluded that the structures of reactive dyes/PSt photonic crystals on mulberry silk fabrics are orderly arranged, showing uniform and bright structural colors; And with the decrease of the particle size of colloidal microspheres, the corresponding structural colors also show different hues such as red, orange, green, blue, and purple, and an obvious blue shift occurs [6].…”

“…Graves et al added photosensitive pigments and thermal pigments to the spinning solution through electrospinning to prepare electrospun cellulose acetate fiber with corresponding color-changing ability, which filled the research gap of photon sensor in electrospun cellulose acetate (CA) and obtained fabrics with photothermal color changing ability [5]. Guo et al took carbon nanotube/cotton composite yarn (CCY) as the core and nanofiber polyurethane/ temperature sensitive ink as the sheath and prepared skin core nanocomposite yarn with excellent mechanical properties, electrothermal properties, and electrochromic properties; that is, color change will occur when there is a charge on the fabric [6]. J. M. et al synthesized magnetic nanosphere with magnetochromic ability by the hydrothermal method, mixed it with resin polyethylene glycol diacrylate (PEGDA), and then irradiated it with ultraviolet light to prepare cured color fiber.…”

In order to improve the color saturation of textile structured chromogenic photonic crystals, this paper proposes that the dye adsorbed PSt structural elements (reactive dyes/PSt microspheres) on the outer surface can be used to construct electrochemically structured chromogenic photonic crystals on mulberry fabrics by digital printing. In this method, the adsorption conditions and adsorption model of dyes on the surface of PSt colloidal microspheres were studied. The structure and morphology of reactive dyes/PSt microspheres, the arrangement of the obtained photonic crystals, and the structural chromogenic effect were characterized. The results showed that the amount of dye adsorbed on the surface of microspheres increased significantly with the increase of adsorption temperature from 25°C to 65°C. When the adsorption temperature continued to rise to 75°C, the dye adsorption capacity on the surface of PSt microspheres did not increase significantly. The adsorption model accords with the Langmuir model; reactive dye/PSt microspheres have a typical core-shell structure, and the particle size of the microspheres is slightly larger than that before adsorption. Conclusion. The reactive dye/PSt photonic crystal chromogenic electrochemical structure constructed on the surface of white silk fabric has a regular and orderly arrangement of microspheres, showing bright structural color.

“…The process of computer color matching begins when the computer was born, and it played a vital role in the continuous development of the textile industry [ 4 ]. The development of computer color matching calculation saves the dyeing and finishing process in the production process of dyed yarn, avoids the problems of staining and infection, and reduces the defects caused by fiber shrinkage or different dyeing properties during finishing [ 5 ]. In the long-term development and progress, many different color matching theories and technologies have also been born.…”

In order to explore the influencing factors of the extraction of vegetable dyes, a research method for the extraction and dyeing of traditional vegetable dyes was proposed. In this paper, the effects of extraction temperature, extraction time, and the ratio of solid to liquid on the extraction effect were discussed through orthogonal experiments. The dyeing process of silk extract was used in this study. The silk fabric was directly dyed with natural dye from peach leaves, compared with the three dyeing methods of premordant, same-bath mordant, and postmordant, and the color fastness to soaping of the dyed fabric was tested. The results show that the color fastness to soaping of leaf-dyed fabrics conforms to the national standard of superior grades, which effectively proves the correctness of the algorithm and model nature and superiority.

Surface functionalization of greige cotton knitted fabric through plasma and cationization for dyeing with reactive and acid dyes

et al. 2021

Dyeing cotton fabrics with anionic dyes produces high e uent loads and requires a considerable amount of water and energy due to the electrostatic repulsion with cellulose. Therefore, several approaches have been researched to increase the e cacy of cotton dyeing. One is the cationization, which adds cationic sites to the cellulose. Another is the treatment of the cotton surface with plasma. In this paper, the combination of both techniques was investigated. Two commercially available cationic agents were used: 3-chloro-2-hydroxypropyl trimethyl ammonium chloride (CHPTAC) and poly[bis(2-chloroethyl) etheralt-1,3-bis[3-(dimethylamino)propyl]urea] quaternized, a novel cationic agent also known as Polyquaternium2 (P42). The plasma treatment was performed using a dielectric barrier discharge atmospheric plasma facility, helium was used as seed gas and 1.5 % of oxygen was injected. The cationization and plasma treatment were performed on greige cotton fabric, an innovative and sustainable approach that eliminates conventional scouring and bleaching processes. The cationic and plasma treated samples were dyed using Reactive Red 195 and Acid Blue 260 dyes. The effect of the treatments was evaluated by different characterization techniques such as X-ray photoelectron spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The plasma treatment slightly increased the light fastness for some samples, but the cationization tends to prevail over the plasma treatment. The best results were attributed to the samples pretreated by CHPTAC, which presented the highest K/S and lowest unlevelness for samples dyed with reactive and acid dyes. CHPTAC is the most common cationic agent for textiles, but its industrial use is limited due to safety criticisms. The combination between plasma and P42 resulted in the same color strength as the conventional reactive dyeing. Therefore, this approach offers a safer alternative to the conventional cationization process.
