Traditional textile dyeing industry usually use chemical pigments and dyes, which bring about a large amount of colored wastewater causing serious environmental pollution . Replacing the traditional high pollution dyeing methods to realize eco-friendly dyeing is very important to the textile dyeing industry, structural colorization maybe one of the most promising methods. In this study, a novel approach was proposed to fabricate eco-friendly coloration of textile originating from polydopamine (PDA) structural color nanofilm with high colorfastness. Four different bright colors were obtained by the polymerization of PDA nanofilm with different reaction times on cotton fabric. However, capillary tension during the formation of PDA nanofilm and weak interaction with fabric substrate resulted in cracking and poor colorfastness. The novel synthesis adhesive of poly (glycidyl methacrylate co-polyethylene glycol methyl ether methacrylate) containing reactive epoxy groups was used to avoid cracking and improve the colorfastness which would form covalent bond on the interface between structural color film and substrate. Therefore, crack-free PDA structural color nanofilm with high colorfastness on cotton fabric surface was obtained. This facile approach provide novel idea for eco-friendly dyeing different kinds of textiles with structural color boosting the cleaner dyeing in textile industrial field.

As a means of preventing environmental damage caused by synthetic dyes, eco-friendly textile dyeing with natural dyes is gaining popularity worldwide. This study focused on the extraction of dyes from the leaf of Dillenia indica ( D. indica ) tree using an ultrasonic extraction technique and applied on the organic cotton fabrics. The ultrasonic method was used for both extractions of D. indica dyes and dyeing of organic cotton fabrics. Here, the amount of D. indica powder used were 5% and 6.67% for producing light and dark shade, respectively. The investigation of the color fastness to washing, rubbing, and light for the dyed organic cotton fabrics indicated an excellent rating. The spectrophotometric analysis revealed the L* (lightness or darkness), a* (redness or greenness), b* (yellowness or blueness), C* (chroma), h* (hue), R% (reflectance), and K/S (color strength) values, which accurately represented the shade of the dyed organic cotton fabric. To understand the interaction between D. indica dye and organic cotton fabrics, different characterization including, Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were performed. The characterization outcomes confirmed the successful deposition of D. indica dyes on the organic cotton fabrics. The other comparable testing results such as bursting strength, air permeability, and thermogravimetric analysis (TGA) of dyed and undyed organic cotton fabrics were in the acceptable range. One of the important findings of this research was no chemicals were utilized during the extraction and dyeing of organic cotton fabrics. This process can be referred to as completely chemical-free and advantageous for the environment because no chemicals were needed during extraction or dyeing. Therefore, the natural dye extracted from D. indica is extremely promising and could be a viable option for the sustainable dyeing of cotton fabrics in the textile dyeing industry.

The problems of difficult dyeing, poor dyeing fastness, and dyeing pollution of aramid are always great obstacles in the practical application. In theory, constructing particular nanostructures instead of dyes on aramids to achieve bright structural colors will be an effective strategy. However, it is still challenging to construct particular nanostructures on aramid fabric surfaces because of their roughness. Here, beautiful and noniridescent structural colored aramids with excellent light fastness were achieved by spraying a thin layer of randomly distributed nanospheres on the surface of adhesive-modified aramids. Moreover, different bright structural colors and colorful patterns were obtained by simply controlling the size or refractive index of the spheres. Importantly, the light fastness of the structural colored aramid can reach levels 6–7 or higher. The simple and eco-friendly coloring technology can be compatible with industrial equipment to obtain stable multicolored aramid products, exhibiting great real potential applications.

Conventional textile dyeing relies on the use of dyes and pigments, which can cause severe environmental contamination and waste a large amount of water. Structural coloring is one of the effective ways to achieve environmentally friendly coloring of textiles. In this work, three plant polyphenols with the same o -benzenetriol structure (tannic acid (TA), gallic acid (GA), and tea polyphenol (TP)) were selected as raw materials. Three plant polyphenols can quickly form nanofilms at the gas-liquid interface through a Schiff base reaction with polyethyleneimine (PEI) under mildly alkaline conditions, which were deposited to the surface of silk fabric, allowing precise control over the thickness of film by adjusting the time, resulting in various structurally colored silk fabric. This method for creating structural colors is not substrate-specific and enables the quick production of structural colors on various textile substrates. Furthermore, the structural color silk fabric based on plant polyphenol has antibacterial performance. This textile coloring method is simple, cost-effective and environmentally friendly, providing a new approach to eco-friendly textile dyeing.

Currently, wood dyeing technology plays an important role in its enhancing aesthetics and market competitiveness. However, still facing the dual challenges of insufficient color fastness of dyeing and environmental pollution caused by dye wastes generated during the dyeing process. Herein, an efficient and environmentally friendly dyeing method was proposed to improve color fastness utilizing chemisorption and electrostatic adsorption in low concentration dyeing solution. The chemical modification of Ayous wood using 2,3-epoxypropyltrimethylammonium chloride was carried out by introducing the cationic groups to reduce the dyeing resistance and increase the binding force of dye molecules on the wood. Kinetic and thermodynamic analyses revealed that the adsorption behavior between cation-modified bleached wood (CBW) and acid dyes adheres to the quasi second-order kinetic model (R 2 = 0.98) and Freundlich isothermal model (R 2 = 0.91), suggesting an adsorption process in which chemical adsorption dominated. Therefore, there was a significant increase in color fastness. Compared to the traditional dyeing method, the quantity of dyes consumed in this method can be reduced by 40%, significantly diminishing the environmental load of dyeing waste liquid. This study offers an efficient and environmentally friendly modification strategy for wood dyeing, highlighting a potential of CBW for practical applications.

Traditional dyeing utilizes a substantial amount of water and necessitates the incorporation of significant quantities of dyes, auxiliaries, and salts, leading to the discharge of highly concentrated organic wastewater and severe water pollution issues. In this study, a novel pyrazolone benzothiazole disperse dye and its triazine disperse reactive dye were designed with the same yellow shade and synthesized. The results showed that the synthesized dyes could successfully realize one-step dyeing of cotton, polyester, and polyester-cotton in supercritical CO 2 . At 100℃, 24 MPa, 60 min, and 2.5 % (o.w.f.) of dye concentration, the K/S value of polyester-cotton fabric was 8 by using the same amount of disperse dye and disperse reactive dye. When disperse reactive dye was used at 100℃, 24 MPa, 60 min, and the concentration of 1.5 % (o.w.f.), the K/S value of cotton fabrics can reach 7.3, and their σ K / S values were less than 0.03 and 0.006, respectively. Moreover, polyester reached the maximum K/S value of 15.96 at 120°C, 24 MPa, 60 min, and a dye concentration of 2.0 % (o.w.f.) with disperse dye. The σ K / S value was below 0.045. The fastness of washing and rubbing was above 4. This study provides novel disperse dye structures and dyeing methods for ecofriendly textiles dyeing in supercritical CO 2 , especially for one-bath low temperature dyeing polyester-cotton fabrics.

Pigment foam dyeing is one of the most environment-friendly and effective ways to realize saving water and energy. However, the agglomerate of pigment particles causes the negative color parament, limiting the color regulation and matching of textile dyeing. In this work, the nanoscale polymer-encapsulated three-primary-color-pigments hybrid latexes have been investigated for foam dyeing of cotton/polyester (C/P) blended fabrics. The optimized pigment hybrid latex foam dyeing processes for C/P blended fabrics were determined involving the dip-nip pressure, baking temperature, and baking time. The foam color matching system of nanoscale pigment hybrid latex was compared with the conventional mixture of pigment and binder. It was found that the color control system pigment hybrid latexes can dye fabrics with not only high color levelness and rubbing fastness, but also a wide range of different hues and shades by matching these primary colors. Interestingly, the color difference (∆ E ) of dyed blended fabrics using three primary pigments with a mixing ratio of 1:1:1 decreased by 57.4% from 0.54 to 0.23 in comparison with that of the conventional system, due to nanoscale hybrid latex particles as a determination faction of color matching in pigment foam dyeing. It is evident that the eco-friendly dyeing method with the color regulation and matching here could significantly enhances the quality of dyed fabric production, and provides a viable and promising prospect in the industrial-scale.

By modifying the structure of the reactive group, the dye VS-GN containing two sulphatoethylsulphone groups based on the triphenodioxazine chromophore was developed. The solubility of VS-GN reached 300 g/L at 25°C. The substantivity and reactivity were 49.3% and 53.1%, respectively. VS-GN showed excellent stability under salt–alkali and alkali stress. Environmentally friendly dyeing methods, including low liquor ratio and cold pad-batch dyeing techniques, were successfully applied for the reactive dye VS-GN. VS-GN completed the exhaust dyeing process at 60°C, and its fixation on cotton fabric was 85.9% at a dye concentration of 2.0% when the liquor ratio was 1:6 and the concentration of Na2CO3 and Na2SO4 were 10 and 80 g/L, respectively. The fixation of the dye VS-GN on cotton fabric using the cold pad-batch dyeing method (10 mL/L of NaOH, 38 oBe’, 20 g/L of Na2CO3, and a batching time of 8 h) was 86.4% at a dye concentration of 20 g/L, which was 27.4% higher than that of conventional reactive brilliant blue KE-GN. The results of the levelness of the dyed cotton fabrics showed that the dyed cotton fabric dyed with VS-GN exhibited a good dyeing level with a low value of ΔE (<0.4). The results of color fastness at a 1/1 standard depth showed that the light fastness of the dyed cotton was grade 4. The dry and wet rubbing fastnesses of the dyed cotton fabric were grades 4–5 and 2–3 or 3, respectively. The washing fastness of the dyed cotton fabric was grade 4 or 4–5.

Dye/polymer nanospheres , a new type of colorant , are applied in various applications in printing inks, coatings, textiles and other fields by virtue of its excellent color properties. In this research, we adopted a novel composite dye nanospheres modified with polyethyleneimine , which was further applied to the environmentally friendly dyeing of cotton fabrics. After modification, the cationic polyethyleneimine composite dye nanospheres (PDNP) have homogeneous particle size, better monodispersity and stability in aqueous solution. In addition, the hydrated particle size increased by 10 nm and the zeta potential changed from −30.4 to 40.7 mV after polyethyleneimine modification. Meanwhile, the color depth of cotton fabrics dyed with different colors of PDNPs is 3–5 times of the corresponding dye colored samples. The color fastness and durability of the PDNPs dyed cotton fibers are satisfied for practical applications. The colored PDNPs can directly dye untreated cotton fabrics without adding salt and alkali, implying a simple dyeing process and pollution reduction.

Structural coloration as the most possible way to realize the ecofriendly dying process for textiles or fabrics has attracted significant attention in the past decades. However, photonic crystals (PCs) are a typical example of materials with structural color usually located on the surface of the fabrics or textiles, which make them not stable when rubbed, bent, or washed due to the weak interaction between the PC coatings and fabrics. Here, double networks were constructed between the PC coatings and the fabrics for the first time via a hydrogen bond by introducing tannic acid (TA) and dynamic cross-linking with 2-formylphenylboronic acid to increase the wash resistance of the structural colored fabrics. On modifying the monodispersed SiO2 nanoparticles, poly(dimethylsiloxane), and the fabrics, the interaction between the PC coatings and the fabrics increased by the formation of double networks. The structural color, wash, and rub resistance of the PC-coated fabrics were systematically studied. The obtained fabrics with the TA content at 0.030% (SiDT30) showed the best wash and rub resistance. The construction of double networks not only improved the wash and rub resistance of PCs but also retained the bright structural color of the PC coatings, facilitating the practical application of structural coloration in the textile industry.

To investigate the influence of cotton wettability on its dyeing properties in a silicone non-aqueous dyeing system, alkali pretreatment was performed before dyeing. The dyeing properties and dyeing kinetics of reactive dyes in the non-aqueous system and a conventional dyeing system were compared. Alkali pretreatment significantly improved the wettability of cotton fiber by removing wax and pectin. The adsorption rate of dye increased with increased cotton fiber wettability using the non-aqueous system, while it barely changed using the conventional system. Pseudo-second-order kinetics fit well with dye adsorption for both systems. Dye fixation improved by 30% at a concentration of 2% owf, along with better levelness and color depth of the dyed cotton fiber, using the silicone non-aqueous system without salts and dispersants.

Natural dyes commonly exhibit low dye uptake and inferior color fastness in textile applications, making the utilization of mordants necessary for enhancing dyeing performance. However, ecological toxicity and low biocompatibility are the drawbacks of traditional metal mordants. This study proposed an eco-friendly alternative by employing Phyllanthus emblica (PE) as natural mordant, and systematically explored its enhancement mechanism and mordanting effects on silk dyed with Artemisia argyi dye. The results demonstrated that the addition of PE extract under the dyeing conditions (pH 4, 90 °C, 30 min) significantly enhanced the color depth of silk fabric, as indicated by an increase in the K/S value from 2.82 to 5.05. The color fastness was also improved, with both washing and rubbing fastness increasing by approximately 0.5 grades. Furthermore, the dyed fabric exhibited excellent antibacterial activity, achieving a 93.03% bacteriostatic rate against Staphylococcus aureus. This study provides new insights for developing eco-functional textiles through sustainable dyeing processs.
