Microbial dyes have received substantial attention because of their natural environmental protection, simple access, and reduced regional and seasonal restriction. In this work, a microbial dye, the yellow pigment produced by Metarhizium anisopliae , was first studied then applied. The strain produced by the culture was identified, and the conditions for producing yellow pigment were optimised. Further, the stability of M. anisopliae yellow pigment was examined, and the pigment was applied to the dyeing of silk and wool fabrics. The results showed that the homology of the strain with M. anisopliae was 99.98%. In liquid fermentation culture, the optimal carbon source was glucose, and the dosage was 30 g/l. The maximum pigment yield can be obtained by culturing with 4% v/v of inoculation quantity at pH 7 and 30 °C. In addition, the effects of pH, temperature and metal ions on the yellow pigment of M. anisopliae were significant. The optimum dyeing process conditions were dyeing temperatures of 80 °C for silk and 90 °C for wool, with a dyeing time of 60 min. This research developed a novel microbial dye and studied its application for the dyeing of protein fibres.

In this paper, highly absorbent poly(vinyl alcohol- co -ethylene) nanofibre membranes modified by β-cyclodextrin were prepared to adsorb dyestuff from water, and 1,2,3,4-butanetetra carboxylic acid was used as a crosslinking agent, which greatly enhanced the adsorption capacity of the modified membranes. Field emission scanning electron microscopy and Fourier Transform–infrared spectroscopy were used to characterise the surface morphology and chemical structures of the membranes. Methylene Blue (MB) was used as the main adsorbed dye. The effect of pH value and concentration of the MB solution were also investigated, and equilibrium adsorption reached 139.2 mg/g when the pH value was 10.0. The adsorption process fitted well with the Langmuir adsorption isotherm model and was in accord with the pseudo-second-order kinetic model. Moreover, the modified membranes proved to have selective adsorption, especially for some cationic dyes other than MB, and had the potential to be recycled multiple times.

A new group of azo disperse dyes prepared by the Ugi four-component reaction were used to dye polyurethane fibres. It was found that all the new dyes showed excellent fastness properties. One of the new dyes was selected to investigate the adsorption properties on polyurethane fibres, including the dyeing rate, adsorption isotherm, surface adsorption state, colour characteristics and colour fastness. The results were compared with those of CI Disperse Orange 3, which has the same parent structure as the new dye. The results indicated that the new dye has a lower dyeing rate and solubility but a higher affinity and adsorption capacity than the conventional dye due to its larger molecular weight and size. In addition, the aggregation of the new dye on the surface of polyurethane fibres occurred at higher concentrations whereas the conventional dyes aggregated at a lower concentration, resulting in lower colour fastness. This demonstrates that these new dyes derived from the Ugi four-component reaction are worth developing further and are of great application value for polyurethane fibres.

Fresh activated carbon (FAC) was oxidised by nitric acid and then the silane coupling agent was grafted onto the surface of FAC under ultrasonic conditions to obtain modified activated carbon (MAC). The chemical oxygen demand was used as the main evaluation index in the wastewater. The effects of benzene, aniline, 2-mercaptobenzothiazole and methylene blue on the adsorption mechanism and performance of FAC prior and postmodification were investigated by different adsorption models. All of them fitted the Langmuir monomolecular adsorption model. The adsorption capacity of MAC was 1.07, 1.12, 1.56 and 0.62 times that of FAC, respectively, which had a better adsorption effect on hydrophobic organic compounds. The maximum adsorption capacity increased due to the existence of competitive adsorption in multicomponent absorption. Texture properties of activated carbon were characterised by scanning electron microscopy, Fourier Transform-infrared and Brunauer–Emmett–Teller theory, which show that the surface morphology became spongy, and that Si–O–C and Si–O infrared peaks appeared. In addition to the mesopore volume, the specific surface area, pore volume and micropore volume decreased slightly after the modification.

Novel hollow fibre polysulphone (PSF) separation membranes were prepared via the incorporation of carboxylated graphene oxide (cGO) in membrane matrix during the dry-wet spinning process to improve the membrane performance of water flux and dye adsorption. The surface composition and morphology of the prepared cGO-incorporated hollow fibre membranes were characterised by means of Fourier Transform–infrared spectra and scanning electron microscopy. The effects of different cGO contents on membrane surface hydrophilicity, separation performance, anti-compaction and adsorption properties were investigated through measurements of the water contact angle, cross-flow filtration and methylene blue (MB) adsorption experiments. The results demonstrated that the cGO-incorporated membranes had more hydrophilic surfaces, higher permeation flux, better anti-compaction properties and a higher adsorption rate of MB than that of the PSF control membrane. When cGO content was 0.45 wt.%, the pure water flux of the modified membrane increased from 90.56 to 148.26 l m −2 h −1 at 0.1 MPa; also, rejections of bovine serum albumin and polyethylene glycol (PEG-20000) maintained relatively high values of 98.81 and 93.89%, respectively. The incorporation of cGO nanosheets could effectively improve membrane anti-compaction properties and the adsorption rate of MB.

A new kind of hetero-bifunctional reactive dye containing 2-ethoxy-4-chloro- s -triazine, with better activity matching with β-hydroxyethyl sulphone sulphate at a low fixation temperature, was successfully synthesised and characterised. An ethoxy group was designed to be introduced into triazine to increase the substantivity and the reactivity of the dyes. Thereby, the fixation of mono- s -chlorotriazine/hydroxyethyl sulphone sulphate (KM-type) bifunctional reactive dyes on cotton was improved, and dyeing under mild conditions with high fixation was realised. Nineteen dyes with orange, red and blue colours were synthesised and characterised by UV-Vis and infrared spectroscopy and mass spectrometry. Synthesised dyes were dyed at 60, 75 and 90°C, respectively. Exhaustion and reactivity for all of the ethoxy-containing KM-type dyes was over 90% at the optimal temperature, and fixation was over 87%, which was higher than the ethoxy-free comparative dyes. The optimal fixation temperature of ethoxy-containing dyes was initially reduced to 75°C, and then to 60°C. Compared with comparative dyes, the wash fastness and light fastness were basically unchanged, and the wet rub fastness of the H-acid series was reduced by one grade.

Hydrophobic polyvinylidene fluoride (PVDF) hollow fibre composite membranes were prepared by the dilute solution coating process to build a special surface structure that was similar to the dual micro-nano structure on the lotus leaf. Poly(vinylidene fluoride-co-hexafluoropropene) was chosen as the hydrophobic polymer candidate in dilute solution. Membrane morphology and surface hydrophobicity were evaluated by scanning electron microscopy and dynamic water contact angle measurement. The prepared PVDF hollow fibre membranes were employed to separate dyes (Congo Red and Methylene Blue) from water by vacuum membrane distillation. The effects of operational conditions (feed temperature, vacuum pressure and feed flow rate) on the vacuum membrane distillation performance of different PVDF membranes were investigated. The results indicated that the water contact angle values of PVDF composite membrane surfaces improved from 93.6° to 130.8°, which was mainly attributed to the formation of micro-nano rods. This structure was similar to the dual micro-nano structure on the lotus leaf. Under test feed temperature, vacuum pressure and feed flow rate conditions, the dye rejection rate of Congo Red and Methylene Blue by the hydrophobic PVDF hollow fibre membrane remained above 99.5% and 99%, which was higher than that of the pristine PVDF membrane (99% and 98%, respectively). In addition, the hydrophobic PVDF hollow fibre composite membrane showed higher permeation flux under different conditions compared with the pristine PVDF membrane, which was attributed to membrane surface hydrophobicity and the electrostatic interactions between dyes and the PVDF membrane surface.

To improve the properties of titanium dioxide particles and realise their firm anchorage in blue light curing film, three modified titanium dioxide particles were prepared by grafting 3-(trimethoxysilyl)propyl methacrylate, 3-aminopropyltriethoxysilane and hexadecyltrimethoxysilane. The surface changes of titanium dioxide particles after modification were characterised. The dispersion stability, photo-polymerisation, rheological and mechanical properties of modified titanium dioxide blue light curing inks were investigated. Results showed that compared with native titanium dioxide, modified titanium dioxide particles were more appropriate for blue light curing ink. The particle sizes of the three modified titanium dioxide particles became smaller, their surfaces exhibited hydrophobicity, and the viscosity of the modified titanium dioxide inks decreased slightly. Of the three modified titanium dioxide particles, 3-(trimethoxysilyl)propyl methacrylate- and hexadecyltrimethoxysilane-modified titanium dioxide particles exhibited better dispersion stability in blue light curing ink. In particular, 3-(trimethoxysilyl)propyl methacrylate-modified titanium dioxide blue light curing ink showed the best photo-polymerisation and mechanical properties, which indicated the participation of the pigment grafted by double bonds in the blue light curable polymerisation. Using modified titanium dioxide in blue light curing ink, the dry/wet rubbing fastness of the printed fabrics improved.

In this study, a hemicyanine dye, trans-4-(4-(diethylamino)styryl)-1-ethylpyridinium bromide (DYE-BD), was synthesised and simulated. The maximum absorption wavelength of DYE-BD was calculated with the same basis set by using the Gaussian 09 software based on different methods, while time-dependent density functional theory was applied to simulate the maximum emission wavelength of the designed dye. The changes in enthalpy and Gibbs free energy were simulated at the b3lyp/6-31G(d) level, and energy changes in the luminescence process were assessed using mathematical methods. Furthermore, DYE-BD was used to colour acrylic fabric following the typical dyeing procedure for cationic dyes. The photostability of the synthesised dye was analysed using quantum theory and mathematical methods. The synthesised dye, analysed using the Ecological Structure Activity Relationships class program, had no toxicity to aquatic life, while the acrylic fabrics dyed with DYE-BD met the fluorescent orange requirements for background and combined performance materials according to the EN ISO 20471:2013 standard.

Grafting modification is a common method for improving the specific properties of polysaccharides. Herein, we synthesised sodium alginate-g-poly (acrylic acid) (NaAlg-g-PAA) as a novel printing thickener via catalysis of horseradish peroxidase and hydrogen peroxide in the presence of acetylacetone. The synthesised products were characterised by Fourier Transform–infrared spectroscopy and polar nuclear magnetic resonance spectroscopy, which confirmed that the PAA was successfully grafted onto the hydroxyl groups at carbon atoms (C2) of sodium alginate. The optimal grafting percentage and grafting efficiency reached 51% and 96%, respectively. Compared with native sodium alginate, the grafted copolymer NaAlg-g-PAA exhibited better thermal stability, rheological and printing properties. This work provides an efficient and promising approach for modifying polysaccharides like alginates and could be used as an alternative to conventional chemical modification.

Enzymatic coloration of fabrics has received worldwide attention in recent years. In order to improve the dyeing properties of enzymatically coloured fabrics, a novel strategy using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC), a biological coupling agent, to pretreat wool fabric was employed in this paper. Enzymatic coloration of wool fabrics with syringic acid was carried out in the presence of laccase from Trametes versicolor . The effect of different periods on laccase-catalysed polymerisation of syringic acid was examined by UV-vis spectroscopy. Enzymatic coloration results of dyed wool fabrics were evaluated by means of K / S value and colour difference ( ∆E* ). Process parameters, including the dosages of syringic acid and incubation time, that influenced the colour depth were studied. Meanwhile, the colour fastness and levelness of dyed wool fabrics were tested. The results showed that the UV-vis absorbance of reaction solution increased as oxidation time elapsed, and a new peak appeared at 360 nm. After pretreatment, the K / S values and colour difference values of wool fabrics dyed with poly(syringic acid) improved appreciably compared with the control samples without any pretreatment. Moreover, pretreated wool fabrics showed better dyeing fastness and levelness than control samples.

Three novel tetraphenylethene–organophosphorus dyads – (6-oxido-6 H -dibenz[c,e][1,2]oxaphosphorin-6-yl)[4-(1,2,2-triphenylvinyl)phenyl] methanol, diphenyl {hydroxy[4-(1,2,2-triphenylvinyl)phenyl]methyl} phosphine oxide, and di(3,5-dimethylphenyl){hydroxy[4-(1,2,2-triphenylvinyl)phenyl] methyl} phosphine oxide – were synthesised and characterised by 1 H, 13 C, and 31 P nuclear magnetic resonance spectroscopy, mass spectrometry, and elemental analysis. The photoluminescence properties were studied. All three dyads exhibited intense solid-state blue emission peaking at 449–466 nm, and also displayed aggregation-induced emission behaviours. The emission decays of these dyads in the solid state also fitted well with a triexponential model with an average lifetime of 2.65–4.42 ns. The experimental results demonstrated that the luminescent properties are highly dependent on the nature of the organophosphorus groups. The choice of phosphorus-containing components can cause variations in the photoluminescence emission and photoluminescence decays.
