Currently, the quest for bamboo materials with high color fastness, rich colors and environmental friendliness is rapidly rising due to its potential applications in construction, furniture and decoration. However, finding an easy-to-operate and environmentally friendly dye for bamboo is a necessary task because of the difficulty in treating the dyeing waste liquid of acid dyes and the complexity of the production process of reactive dyes.Five formulations involving metal polyphenol complexes were employed to straightforwardly produce eco-friendly dyed bamboo and the impact of various formulations on the light aging resistance of the dyed veneers was examined. The results indicated that the light resistance of bamboo veneer dyed with the solution containing only FeSO 4 ·7H 2 O and tannic acid reached level 4, surpassing the undyed bamboo veneer by three levels. The mechanism of enhanced lightfastness of dyed bamboo veneer was elucidated by XPS analysis. The polyphenol iron complex serves a dual purpose: it absorbs ultraviolet rays and scavenges free radicals within the system. Additionally, it reduced the oxidation of phenolics in the substrate, transforming them into dark-colored quinone structures. This process enhanced the light-aging resistance of the finishing materials. Therefore, this work provides a simple and environmentally friendly method for changing the color of bamboo and provides a new idea for the selection of dyes for bamboo dyeing in actual production.

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.

A polymerizable red dye 1-(6-acrylamidohexylamino) anthraquinone (AHAQ) was synthesized and used to prepare colored polymer latexes using styrene and butyl acrylate as main monomers. Influences of the initiator and surfactant amounts, oil/aqueous phase ratio, and AHAQ content on the polymerization process, the particle size, and surface tension of the resulted latex were investigated, and the migration resistance and light fastness of the red latex films were determined. Results showed that the polymerization was carried out smoothly, and the miniemulsion polymerization mechanism was confirmed by monitoring the dimensions of oil phase before and after polymerization. The latex particle size can be adjusted by varying the surfactant amount, and when AHAQ content was 0.2–1 wt% of total monomers, the encapsulation efficiency and dye conversion could be achieved to 98.7 and 96.3%, respectively. The UV–vis spectra of AHAQ and its corresponding covalently colored polymer indicated that the maximum absorption peak was the same, meaning that the chemical structure of chromophore in AHAQ maintains unchanged after undergoing polymerization. The migration resistance and light fastness of the covalently colored latex films were much better than that of the correspondingly non-covalently colored ones.

Herein, a new kind of hetero-bifunctional reactive dyes with high light-fastness was designed and synthesized by introducing benzene sulfonamide and its derivatives into the triazine ring. Benzene sulfonamide or its derivatives and 2-amino-5-naphthol-7-sulfonic acid (J-acid) were condensed with cyanuric chloride to synthesize coupling components, which were then coupled with the diazo salt of 4-(β-sulfatoethylsulfonyl)aniline. The dyes were characterized by IR spectroscopy and MS. The color fastness test proved that the light-fastness of the dyes could be improved by 1 grade via the introduction of benzene sulfonamide derivatives into the triazine ring when compared with the case of the control dyes. Fluorescence spectra demonstrated that after the introduction of benzene sulfonamide derivatives, the dye molecule could return to the ground state from the excited state and emit fluorescence; in addition, the introduced benzene sulfonamide derivatives helped to deteriorate the adverse effect of UV light on the dye. Moreover, the dyeing results showed that the dyes containing the sulfonamide groups had equal dyeing properties when compared with that of the control dyes.

A novel green fluorescent dye, 4-hexylamino- N -(2-hydroxy-1-hydroxymethylethyl)-1,8-naphthalimide (AHHNA), was designed and synthesized, and then used as a chain extender to prepare a series of intrinsically green fluorescent polyurethane (PU) latexes. The chemical structure of AHHNA and the properties of the fluorescent PU latexes and their films were characterized. It was found that the UV–Vis and the fluorescent spectra of the PUs remained fairly consistent with AHHNA, and the fluorescence emitting capacity of 1,8-naphthalimide group was enhanced by covalently bonding AHHNA onto the PU chain. The amount of AHHNA used in the latex preparation had no obvious effect on the latex colloid properties including particle size, poly index, and zeta potential. Results showed that the color difference (Δ E ) and the extraction rate ( R
e ) of the intrinsically fluorescent PU latex film were 5.72% and 3.1%, respectively, while the Δ E and R
e of the extrinsically fluorescent PU latex film were 8.31% and 84.7%, respectively, indicating that the light fastness and the solvent fastness of the intrinsically fluorescent PU latex film were much better than those of the extrinsically fluorescent PU latex film.

In this work, a new method for facile synthesis of covalently colored polyurethane latex was developed. A series of blue dye monomers were synthesized via one-step reaction of a reactive dye and amino compounds, and then employed as chain extenders to react with polyurethane prepolymer in the emulsification process to prepare the covalently colored polyurethane latexes. The chemical structures and the properties of dye monomers and the corresponding polymers were investigated, and the UV–Vis spectra of covalently colored polyurethane featured fairly consistent with dye monomers with maximum absorption wavelength at 620 nm and 580 nm, since the chemical structure of chromophore maintained unchanged. The conversion of dye monomer reached more than 92% with 1.0 wt% dye content, whereas the conversion decreased with the increase of the dye amount and the adding time. Compared with the noncovalently latex film, the light fastness of the covalently colored latex film was greatly promoted due to the chemical bonding of chromophores with polymer matrix.

Polyphenols are a group of natural organic compounds from nature that have been widely used in many fields. Silk, known for its excellent hand and bright luster, is composed of a substance similar to human hair - proteins in large quantities. This study utilized biomass polyphenols, including tea polyphenols (TP), gallic acid (GA), tannin acid (TA), and dopamine hydrochloride (DA), to dye silk fibers for application in wigs. We developed a dyeing method to achieve this goal, successfully producing silk in various colors, including yellow, brown, black, grey, and orange. Among these, samples dyed with polyphenols using Fe 2+ and Ti 4+ mordants, as well as those dyed with a combination of TP and zinc oxide, retained more than 80% of their color depth after 20 washes, demonstrating good wash fastness. Moreover, DA-Fe 2+ , GA-Fe 2+ , TP-Fe 2+ and DA dyed samples achieved a light fastness rating of 5, indicating excellent resistance to sunlight. Additionally, the characteristics and morphology of the silk before and after dyeing were analyzed using various spectroscopic and analytical techniques. Adsorption tests showed that most polyphenol dyes followed the Freundlich isotherm. However, TP self-polymerization and DA/GA with Fe 2+ mordant dyeing aligned with first-order kinetics, while others followed second-order kinetics. The dyed silk fibers exhibited good anti-UV performance and had no significant change in tensile strength. Furthermore, using DA-Fe 2+ to dye the back hair of mice did not result in adverse effects. This method is eco-friendly, mild, and cost-effective, making it highly promising for applications in the wig industry.

A novel water-soluble macromolecular light stabilizer was synthesized by grafting 2-chloro-4,6-bis-[(2,2,6,6-tetramethylpiperidin-4-yl)amino]-1,3,5-triazine onto polyvinylamine. The intermediate 2-chloro-4,6-bis-[(2,2,6,6-tetramethylpiperidin-4-yl)amino]-1,3,5-triazine and the obtained macromolecular light stabilizer were characterized by 1 H NMR, HRMS, IR and UV spectroscopy. Cotton fabrics dyed with C.I. Reactive Yellow 145, C.I. Reactive Red 195 and C.I. Reactive Blue 19 were finished with the macromolecular light stabilizer, and the lightfastness of the dyes was tested. The results showed that the lightfastness of the reactive dyes was improved by 0.5–1.0 grade after being finished and the macromolecular light stabilizer exhibited good wash fastness and thermal stability.

The practical application of a sulphur black dye relies on its ability to dye cotton fibres with pure black colour and maintain the colour with high light fastness. Here, we report a synthesis method to prepare a novel water-soluble reactive sulphur black dye. The approach involves the reduction of CI Sulphur Black 1 to its leuco form and subsequent reaction with a water-soluble intermediate containing reactive groups synthesised from amino acid and cyanuric chloride. The optimal carboxyl and reactive group content of the water-soluble reactive sulphur black dye is 141 mmol/100 g, and the water solubility can reach 92 g/L. The fixation of the reactive sulphur black dye on cotton reaches 89% in a pad dyeing process without using sodium sulphate. The reactive sulphur black dye can achieve a light fastness of grade 6-7, a dry rub fastness of grade 4 and a wet rub fastness of grade 2, comparable or higher than the conventional CI Sulphur Black 1. The dyeing results showed that the novel water-soluble reactive sulphur black dye has excellent performance and good application prospects.
