Monodisperse poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) cationic nanospheres were synthesized by soap-free emulsion polymerization, and were subsequently combined with gardenia to prepare dye/nanospheres. The influence of the concentration of gardenia yellow, rate of vortexing, temperature and pH of mixing on the adsorption capacity and stability of microspheres were thoroughly investigated, and the prepared gardenia/poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) nanospheres acted as liquid pigments to dye the fabric substrates by the impregnation method. In particular, the photostability of gardenia/poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) and the reflection of its dyed fabrics are distinctly described, the comparison of the dyeing property effect between gardenia/poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) and gardenia yellow dyed by mordant dyeing were analyzed. According to the experimental findings, the dyestuff nanospheres have high stability when the pH is 7–8, the mass ratio of gardenia yellow to poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) nanospheres was 12.8:1, the temperature was 60°C for 30 min, and the mixing speed was 500 rpm. Dyeing cotton fabrics with gardenia/poly (methyl acrylate-meth-acyloxy-ethyl trimethylammonium chloride) produced higher color strength and color fastness than the gardenia yellow with mordant dyeing.

A novel method for the selective extraction of gardenia yellow and geniposide fromGardenia Jasminoides, based on a mechanochemical method is described. Without the need of complex separation techniques, gardenia yellow compliant with the national standard could be extracted in a simple fashion. The optimal ball-milling conditions determined were as follows: 30% g/g. active carbon milling at 200 rpm in a planetary mill for 5 min. The extraction conditions of the milled mixtures were as follows: the milled mixtures were extracted with water (liquid-solid ratio 10:1) at 20 °C for 5 min with yields 85% of total geniposide, followed by extraction with 80% ethanol solution (liquid-solid ratio 5:1) and 1% g/g. Tween 20 at 75 °C for 5 min to yield 1.45% ± 0.108% g/g of gardenia yellow. The mechanism of this selective extraction was demonstrated to follow a microstructure change of activated carbon, which occurred during milling and lead to alteration of the corresponding desorption capacities. Compared with traditional extraction methods, this novel extraction technique greatly simplifies the separation process, and proves to be advantageous in terms of low organic solvent consumption, easy operation, rapid process and high efficiency.Keywords:Gardenia jasminoides;gardenia yellow;geniposide;mechanochemistry;selective extraction

Mercaptosuccinic acid (MSA) molecules were inserted into potato starch, leading to the breaking of intrinsic H-bonds within macromolecular chains of starch and the formation of intermolecular H-bonds between MSA and starch, which could be verified by Fourier transform infrared spectroscopy (FT-TR). MSA modified porous starch xerogels (PSX/MSA) were obtained after freeze-drying the MSA modified starch, and they were characterized by field emission scanning electron microscopy (FESEM), exhibiting the intriguing porous structure due to the separation of starch chains by MSA molecules. The PSX/MSA were then used as the adsorbents to remove gardenia yellow (GY), a natural colorant with genotoxicity. Due to the porous structure of PSX and the introduced carboxyl groups from MSA, the adsorption capacity of the PSX/MSA was much higher than that of the starch xerogels alone (SX). The adsorption behaviors of GY by the PSX/MSA fitted both the Freundlich isotherm model and the pseudo-second-order kinetic model, and the efficient adsorption of GY suggested that the PSX/MSA might be potential adsorbents for the removal of dyes from contaminated aquatic systems.

The application of chemical synthetic dyes causes serious environmental pollution and high energy consumption. Natural plant dyes have become the most promising alternative in textile printing and dyeing processing with lower carbon emission. In this work, the properties of water-soluble gardenia yellow natural dye in inkjet printing of wool fabrics were studied in detail. The results of multiple light scattering showed that the gardenia yellow dye ink had high stability. The surface tension and viscosity of the ink can be adjusted by polyol-based organic solvents to obtain a stable droplet morphology. The influence mechanism of sodium polyacrylate sizing agent and polyol solvent on color depth and contour clarity of printing pattern have been deeply studied. After tannic treatment, gardenia yellow inkjet printed wool fabric can obtain satisfactory color fastness. At the same time, gardenia yellow dye endowed wool fabrics with good antibacterial property , and the antibacterial rate against S. aureus and E. coli can exceed 95%. In this study, both inkjet printing and color fixing process are green and non-pollution, which provides an idea reference for the production of natural green antibacterial textiles.

Based on the trend of low-carbon emissions and environmentally friendly development, this paper extracted natural dye from gardenia for cellulose fiber dyeing and endowed them with UV resistance and antibacterial properties. And more attention was paid to the dye structure of the gardenia yellow dye and its alkali-hydrolyzed gardenia yellow dye on dye uptake, UV–visible absorption characteristic peak as well as functional finishing. The main dye components of gardenia yellow dye and its alkali-hydrolyzed gardenia yellow dye were measured by the UV–visible and LC–MS spectrum. The crocin, which was the main dye components in the gardenia yellow dye, presented higher maximum absorption wavelength and darker colors compared with alkali-hydrolyzed gardenia yellow dye, which the main dye components was croceic acid. The cotton fabrics dyed with gardenia yellow dye or alkali-hydrolyzed gardenia yellow dye all indicated well dyeing performacne and functional characteristics such as antioxidant activity, UPF values and antibacterial property against Staphylococcus aureus and Escherichia coli . The main reason for different in the dyeing and functional performance of cotton fabrics dyed with gardenia yellow dye or its alkali-hydrolyzed dye were the removing gentiobiose molecules under alkali treatment, which changed the conjugate systems, ionization capacity, and polyphenols and flavonoids content. And the study examines the dyeing kinetics, adsorption isotherm, and thermodynamics of gardenia yellow dye and its alkali-hydrolyzed gardenia yellow dye on the cationic cotton. It is expected that achievement of this research provide guide to the value adding utilization of agricultural by-products from crop industries and view to investigate the effect of dye composition on the dyeing and functional performance.

Through denaturation and amination of the mixture, consisted of expired cow milk, kaolin and gardenia yellow, in the hot organic solvent that contained alkaline aminosilane coupling agent, then adsorption of diverse acid dyes in the acid condition, thus obtaining active matrixes with different colors. By virtue of the non-catalyzed in-situ reaction among the acrylate groups of pentaerythritol ester compounds and the amino groups of obtained matrixes as well as long-chain alkyl amines, the biomass fluoride-free superhydrophobic doped paints was prepared, however the poor stability was reflected in its anti-wetting coating surface. Furthermore, in order to improve durable superhydrophobicity and multifunctionality of the expired cow milk-based water-repellent paint, the thermally denatured protein, originated from expired cow milk heating, was blended with nanoscale inorganic pigments to accept the before-mentioned procedures of amination and in-situ growth, consequently constructing the multifunctional biomass nonfluorinated chromatic paint with robust superhydrophobic function, moreover its coated fabrics had 155.7° of average contact angle and 1.5° of average sliding angle. Additionally, by only using synergy of complex denaturation and chemical coupling, the expired cow milk could be transformed into UV-photoluminescent nonfluorinated superhydrophobic color paint, the contact angle of such paint-coated fabric was 153.3° and its sliding angle was 2°. Based on the additional function of as-prepared biomass paints, the applications of non-wetted switchable fluorescence imaging as well as photothermal deicing were realized. We believe that the expired cow milk-based multifunctional paints can expand into the fields of outdoor protective textiles, decorative building materials, fluorescent falsification-preventing and ice protection.
