Structural color is an important way to achieve the ecological coloring of textiles. SiO 2 microspheres with sizes in the range of 200–337 nm were synthesized by the Stober method and then covered with highly light-absorbing melanin PDA to form SiO 2 @PDA photonic crystals. The SiO 2 @PDA photonic crystals were assembled onto the surface of white cotton fabrics by gravity deposition to achieve structural color. The addition of polyvinylpyrrolidone (PVP) enhances interfacial bonding by forming multiple hydrogen bonds between its lactam group and the phenolic hydroxyl group of PDA, resulting in a structured color cotton fabric with high color fastness. Scanning electron microscopy (SEM) was used to study the structure and morphology of SiO 2 @PDA microspheres. The chemical compositions of PDA and PVP were surveyed by Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). The surface structural color of cotton fabrics was investigated by UV–Vis reflectance spectroscopy.

Smart textiles with real-time visual monitoring abilities of environmental pH hold significant importance in wearable products. Natural dyes have gained growing interest as eco-friendly pH indicators, however, their stability and large-scale isolation remain challenging. In this work, we developed a type of pH-monitoring colorimetric indicator based on anthocyanins, a natural dye extracted from red cabbage, with enhanced affinity to cotton fiber substrates by utilizing metal salts and biopolymers. Compared to cotton fabric directly dyed with pristine anthocyanins, this colorimetric fabric demonstrates higher color contrast, superior reversibility of color change, and enhanced light and washing color fastness. The color strength (K/S) was significantly improved from 0.136 for untreated fabric to 1.266 for colorimetric fabric, and the excellent colorimetric properties maintained either after over 20 h washing or 12 h exposure to sunlight. This work addressed the issue of the easy light degradation of biomaterials, and provided a feasible optimization strategy for the development and application of environment-responsive biomass colorimetric textiles as smart and wearable products.

A limited selection of natural dyes’ color impedes the development of textile dyeing with natural plant dyes. Inspiring by the conventional coloration of textiles with a combination of three synthetic dyes generally, the present work is to investigate the broadening color shade of dyed wool fiber with ternary natural dye combinations of madder red (MR), gardenia yellow (GY), and gardenia blue (GB) without mordants in a decamethylcyclopentasiloxane (D5) medium. The wool yarn was wetted in an aqueous solution of pH 3 to own a 300% pickup rate, followed by immersion in a D5 medium containing 2% of alcohol ethoxylate (AEO-3) and solid natural dyes at 90°C for 90 min for coloration. The colorfastness to washing was achieved at a 4–5 for fading and a 5 rating for staining for all colors. The XRD patterns and TGA analysis confirmed that the dyeing procedure did not affect the crystallinity nature and stable thermal tendency. SEM images and cross-sections showed that the dyeing procedure did not damage the morphological structure of the wool fiber surface, and the dyes were evenly distributed. Finally, many color shades of dyed fibers were prepared with various dyes’ ratios.

Structural color-generating materials are expected to replace pigments and dyes as a new type of color-developing materials with good light stability and bright colors. Due to the relatively high refractive index of Cu2O microspheres, they have strong Mie scattering in the visible region. Herein, various sizes of Cu2O microspheres were synthesized by a two-step reduction method, and the Cu2O spheres were firmly bonded to the fabrics by using the PVA binder. Four different fabrics (cotton, silk, polyester, and nylon fabrics) were evaluated to investigate the physical properties and color fastness. It turns out that the tensile and tearing properties of the Cu2O structured fabrics decreased to a certain extent, and the bursting properties of fabrics increased, except for the cotton structured fabrics. Meanwhile, all the structural colored fabrics showed excellent color fastness to shearing, rubbing, and washing. This study provides experimental data for developing the application of structural colors on different fabrics.

In this study, a reversible thermochromic wool fabric with excellent color fastness was prepared by reacting thiol-modified thermochromic microcapsules with the fabric. Treatment with tris (2-carboxyethyl) phosphine hydrochloride (TCEP) resulted in the appearance of a large number of thiol groups on the surface of the wool fabric, enabling the formation of disulfide bonds with thiol-containing microcapsules. The effective introduction of thiol groups onto the microcapsule surface and their incorporation onto the wool fibers was confirmed by FTIR analysis. DSC measurements revealed that the color transition temperature of the thiol-modified microcapsules was 48.98 °C. The photos of the color-changing process of the microcapsule solution and the variations in color parameters during the heating-cooling cycles demonstrated the excellent color-changing characteristics of the microcapsules. The covalent bonding between the thiol-modified microcapsules and the wool fabric contributed to its high color fastness. When the dosage of 3-mercaptopropyltriethoxysilane was 10% of tetraethyl orthosilicate, the fading fastness of the thermochromic wool fabric reached grade 3, while the staining fastness reached grade 5. The wet rubbing and dry rubbing fastness were at grade 3 and grade 4, respectively. Even after undergoing 30 cycles of heating and cooling experiments, the K/S value of the thermochromic wool fabric remained stable. Graphical Abstract

Worldwide, 45 million tons of waste cotton textiles are produced annually, of which 75% is burned and buried, leading to serious environmental pollution. In this study, a method for directly preparing colored regenerated cellulose fibers (CRCFs) from dyed cotton textile waste (DCTW) was demonstrated. The tensile strength of CRCFs reached 226 MPa, which was equivalent to that of commercial viscose fibers. CRCFs exhibited excellent color fastness and hydrophilicity. In addition, CRCFs can be reprocessed into secondary CRCFs. The tensile strength of secondary CRCFs was 14.64% less than that of the primary CRCFs due to the reduction in the polymerization degree of secondary CRCFs; however, it also can be woven into fabrics. The exploration of the secondary utilization of CRCFs provides an experimental basis for prolonging the service life of DCTW. This approach of preparing CRCFs achieves closed-loop recycling of waste colored cellulose textiles and prevents environmental pollution caused by decoloring and dyeing.

Metal-phenolic networks (MPNs) have been considered an alternative to the commercial hair dyes. However, it is still challenging to dye white hair black without damaging the hair because the deposition of MPNs is restricted on the surface of the healthy hair. Herein, we develop a novel damage-free strategy that not only promotes surface deposition of MPNs, but also favors internal formation of MPNs. Firstly, basic amino acids that can help open the hair cuticle penetrate into the hair. Then the numerous amino and carboxyl groups of the amino acids serve as coordination sites for Fe 2+ absorption, which facilitates the interfacial and internal growth of MPNs, thereby deepening the color of the dyed hair. As the intake of amino acids increases in the hair, the amount of Fe that enters into the hair increases to enhance the coloration. The dyed hair is capable of withstanding repeated washing with shampoo for at least 15 times without fading. Moreover, the surface MPNs bring about good resistance to UV damage, light fastness, and antioxidant properties, while the amino acids to some extent can repair the potential damage to hair.

Structural color fabrics, which derive their color from the periodic microstructure of photonic crystals (PCs), face a significant challenge in practical applications due to their poor color fastness. The colloidal arrays are prone to collapse under external mechanical forces such as washing and rubbing. Surface encapsulation with polymer presents a promising solution. However, the prevalent use of commercial adhesives with ill-defined compositions hinders the precise understanding and control over the relationship between material properties and color stability. To address this limitation, this study designed and synthesized the UV-curable waterborne polyurethane (UVWPU) with tailored microphase-separated structures by regulating the NCO/OH molar ratio (R value). The synthesized UVWPU emulsions exhibited a translucent light blue appearance, nanoscale particle size, and excellent stability. The cured films demonstrated high transparency (>98 %), tunable mechanical strength, and good water resistance. These UVWPUs were then applied to encapsulate structural color fabrics fabricated by shear-induced assembly of polymethyl methacrylate (PMMA) microspheres of various sizes. The resulting structural color fabrics maintained vivid, angle-dependent structural colors. More importantly, they exhibited dramatically enhanced color fastness, successfully withstanding 45 min of washing, 100 rubbing cycles, 20 bending cycles, extended storage, and exposure to acidic, alkaline, and saline environments without significant color degradation. This work provides a fundamental and practical approach for developing high-durability structural color textiles.
