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.

Biomimetic structural coloration with photonic crystals (PCs) possesses the advantages of eco-friendly coloration, brilliant structural colors, and high colorfastness to light, etc. It is appealing for advanced coloration of various substrate surfaces. However, the fabrication of PCs with iridescent effect and high colorfastness on three-dimensional (3D) irregular substrate surfaces is still challenging. In this work, liquid photonic crystals (LPCs) with high mass fraction (40 wt.%) of colloidal nanospheres were used as the spraying solution to assemble long-range ordered PCs with iridescent effect. Thanks to the fluidity and dynamic reversibility, the pre-crystallized LPCs could disassemble under the applied spraying pressure, which promoted smooth spraying and enabled the formation of atomized micro-droplets. The colloidal nanospheres present in these micro-droplets were able to quickly reassemble and restore their pre-crystallized state. This allowed micro-droplets to connect with each other on the curved or 3D irregulated substrate surface into orderly assembled solid PCs upon the water evaporation, exhibiting brilliant structural colors with iridescent effect. Meanwhile, the use of the spraying solution with high mass fraction of colloidal nanospheres was shown to be effective against the slipping problem of the micro-droplets on 3D substrate surfaces, enabling the fabrication of PCs with pronounced iridescent structural colors on various 3D substrate surfaces (metal, ceramic, rubber, glass and so on). In addition, pre-spraying a specific polymer slurry to form a bearing layer on the 3D substrate prior to spraying the LPC allows improving the stability of the assembled PC structure under external forces (rubbing, washing, etc.), while retaining the refractive index contrast of PCs and thus achieving the consistency between their structural stability and color saturation.

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.

Monodispersed polystyrene (PS) particles were prepared and deposited onto various kinds of textile fabrics using a gravity sedimentation method. The monodispersed PS particles were self-assembled on fabrics to form a photonic crystal, which has an iridescent structural color. The structural color of fabrics was determined by the bandgaps of photonic crystals. Moreover, the effect of the fabric substrate, including the raw materials, base color, and fabric weave, etc., on the structural color of the photonic crystals was studied. Scanning electron microscopy and UV-vis spectrometry were adopted to characterize the structure and optical performance of photonic crystals. The results indicate that the silk fabric with a black base color and satin weave contribute to a bright and pure textile structural color. In order to solve the problem of low color fastness of the structural color on the fabric surface, silk fibroin (SF) was introduced to the PS microsphere solution. Results show that the addition of SF slightly affects the brightness of the structural color, while it has a certain reinforcing effect on the structural color fastness to rubbing and washing.Keywords:photonic crystals;structural color;fabric substrate;silk fibroin;color fastness

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.

In order to develop a kind of color-fasten and durable flame retardant wool fibers , the green and environmentally friendly dye, i.e. sodium copper chlorophyll (SCC) was firstly used to dye the wool fibers, then the dyed wool fibers (DW) was phosphorylated with phosphoric acid to obtain flame retardant wool fibers (FR-W). The results show that FR-W has good color fastness, and the limiting oxygen index (LOI) of FR-W is still as high as 29.6% after 50 times washing, indicating excellent durable flame retardant performance. The char residue of FR-W at 800 °C under air atmosphere is 27 wt%, showing good char forming ability. Compared to the control sample, the peak of heat release rate (pHRR) of FR-W decreases by 65% and the total heat release (THR) of FR-W decreases from 5.2 MJ/m 2 to 4.8 MJ/m 2 . The SCC combined with phosphate groups play the role of gas and condensed phase flame retardant mechanism.

A series of new azo disperse dyes containing the urethane group were synthesized through the reaction between the hydroxyl group in coupling component of disperse dyes and p-toluene isocyanate. The structures of the new dyes were fully confirmed by 1 H NMR, 13 C NMR, FT-IR, MS and Elemental analysis . Their characteristics for the visible-light absorption and color fastness on polyamide fibers were respectively measured and compared with those of the original dye. It was found that the new dyes exhibited hypsochromic effect, and had the nearly unchanged absorption half band and higher molar extinction coefficients , the fastness properties has been greatly improved, especially for the washing and sublimation fastness. The new dyes 2d and 2e containing double urethane groups possessed excellent fastness properties on polyamide fabrics. These two dyes for all the fastness tested, including water fastness, sublimation fastness, rubbing fastness and light fastness, had reached 4–5 and 5 rates. It was very clear that the introduction of urethane group and the increase of molecular weight can effectively improve the fastness of disperse dyes for the polyamide fibers.

Structural color as a revolutionary coloration strategy has been proposed to replace the traditional dyeing and printing process. However, the poor colorfastness and easy crack formation of structural colors on textile fabrics restrict their practical application at present. In this study, poly (tert-butyl acrylate-co-glycidyl methacrylate) (P(t-BA-co-GMA)) copolymers containing reactive epoxy groups with different mass ratios of tert-butyl acrylate (t-BA) and glycidyl methacrylate (GMA) were successfully synthesized, which were used to create structural colors on black polyester fabrics. The results showed that P(t-BA-co-GMA) nanospheres could form crack-free structural colors on polyester fabrics, and the colors vary with the mass ratio of t-BA and GMA to obtain five different colors. The different particle sizes of the different P(t-BA-co-GMA) nanospheres with different refractive indexes and the arrangement of short-range ordered and long-range disordered in microstructures may be the reason of different angle-independent structural colors on polyester fabrics. The P(t-BA-co-GMA) nanosphere structural colors on polyester fabrics possess good abrasion and washing colorfastness. This research provides the experimental basis for the development of crack-free amorphous photonic crystal structural color on fabrics with high colorfastness to promote the practical application of structural color in textile coloration.

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.

Dye-bonded blocked waterborne polyurethanes were developed to synchronously realize coloring and finishing of textiles and improve colorfastness using an anthraquinone chromophore and a methyl ethyl ketoxime blocking agent. The number-average molecular weight of the dye-bonded blocked polyurethane is 2303 g mol−1 and the polydispersity is 1.06, indicating a narrow molecular weight distribution. The maximum absorption wavelengths do not shift after the monomolecular chromophores are bonded to the polyurethane. The self-colored polyurethanes provide better centrifugal stability and water solubility than the dye-mixed blocked polyurethanes. The dye-bonded blocked polyurethane offers good thermal stability below 100 °C and undertakes de-blocking at about 150 °C. The covalent bonding of the anthraquinone moiety with the polyurethane chain and temporary blocking of the terminal isocyanate groups are conducive to enhancing the tinting strength and colorfastness of the treated cotton fabrics. The self-colored blocked polyurethanes with good elasticity and toughness can improve the recovery angle of the treated cotton up to 120°, which can also endow the fabric with wrinkle resistance.

A series of reactive TiO 2 pigments with olefinic double-bonds were prepared by grafting modification of silane coupler KH570 to be covalently anchored in the blue-light curing film, which improved the color fastness to crocking of the printed fabrics significantly. Effects of KH570 concentrations on particle size, surface wettability and dispersing stability of KH570-TiO 2 pigments, photo-polymerization of KH570-TiO 2 bule-light curing inks and tensile properties of curing films were investigated. Color fastness to crocking of KH570-TiO 2 pigment on cotton fabric was explored. Results showed that compared to the native TiO 2 , all the properties of KH570-TiO 2 improved. With the increases of KH570 concentrations, the grafting degrees of KH570-TiO 2 had gradual increase. The surface hydrophobicity and dispersion stability of KH570-TiO 2 pigments, photo-polymerization of KH570-TiO 2 blue-light curing ink and tensile properties of curing films enhanced, especially those of 12∼20KH570-TiO 2 the best. Within the concentrations of KH570 12–20 wt %, the printed fabrics had dry/wet color fastness to crocking no less than 4 grades.

Naturally colored silk (NCS) fades easily during wet processing and home washing due to the loss of pigment, which is accompanied by dissolution of the sericin layer. This study proposed a green and effective strategy for fixing the sericin of NCS to improve the color fastness of NCS textiles under wet conditions. The sericin of NCS was crosslinked with a bifunctional epoxy resin, poly(ethylene glycol) diglycidyl ether (PEGDE), in the presence of calcium chloride as a catalyst. The influences of the concentrations of PEGDE and the catalyst, pH, temperature, and reaction time on the crosslinking effect were investigated. The results showed that crosslinking NCS under optimum conditions could result in a 5.11 % weight gain. After crosslinking, the pigment in the sericin layer exhibited a considerable fixation fastness under wet conditions due to the low solubility of the crosslinked sericin. The K/S value of crosslinked NCS decreased by only 15.9 % after washing 15 times, which is much lower than that of uncrosslinked NCS (43.8 %). Crosslinking of NCS also improved its antioxidant capacity retention against repeated home washing. This study proposed an effective sericin-crosslinking strategy that could be used not only for fixing the color of NCS but also for sericin-grafted textiles and sericin-based biomaterials.
