“…As well known, supercritical dyeing of textiles is a green and sustainable technology by utilizing supercritical carbon dioxide as media, and now can be commercially applied in polyester and other synthesized fiber substrates in recent years [1][2][3][4][5]. However, supercritical carbon dioxide fluid is a typical non-polar medium, so the hydrophilic and/or ionic dyestuffs are not applicable in this kind of medium [6][7][8][9][10].…”

A special dye of SCF-X-ANR02 involving an anthraquinonoid chromophoric system and a new bridge group linked with a dichlorotriazine reactive group was designed and developed at the first time, in order to apply for dyeing cotton and wool substrates with a green technology in supercritical carbon dioxide. Moreover, the dyeing property of the obtained dye was also investigated and compared on cotton and wool fabrics. The results show that the designed SCF-X-ANR02 dye was successfully synthesized by employing an Ullmann reaction with copper as catalyst, as well as a subsequent condensation reaction for bonding a reactive group. Moreover, the chemical structure of the SCF-X-ANR02 dye was well characterized and confirmed by Fourier transform infrared FTIR analysis, nuclear magnetic resonance spectroscopy of 1 H NMR and 13 C NMR, and liquid chromatography-mass spectrometry (LC-MS). The coloration results show that good dyeing properties, such as uptake and leveling behaviors, as well as color fastness were observed on cotton and wool fabrics in supercritical carbon dioxide dyeing media.

“…Supercritical fluid (SCF) technology has been widely applied in various fields including bacterial inactivation and sterilization, chemical reactions, leather processing, extraction of flavours, fragrance and colourant and decaffeination of coffee beans . SCF is a substance that exists when the temperature and pressure exceed its critical point, where in this state, the distinction between vapour and liquid phases does not exist.…”

The present work studied the solubilities of Quercus infectoria gall extract in supercritical carbon dioxide (SC‐CO2) system with the addition of methanol as polarity enhancer. Experimentally, the galls were extracted using SC‐CO2 at different operating pressures (20 to 30 MPa) and temperatures (50 to 70 °C). Six semi‐empirical equations (Chrastil, Adachi‐Lu, del Valle‐Aguilera, Sparks, Kumar‐Johnston and Bartle) were used to explain mathematically the solubility behaviour of the Q. infectoria gall extract. The results demonstrated that the extract solubility increases as pressure increases at fixed temperature, while at constant pressure, it increases with increasing temperature. Apparently, Bartle equation provides best correlation between experimental and calculated solubility data for gall extraction with high correlation coefficient, R2 (0.96), and small absolute average relative deviation (1.52%). © 2017 Curtin University of Technology and John Wiley & Sons, Ltd.

A combined system of coagulation and membrane processes was investigated in this study for reactive dyeing wastewater treatment. Microfiltration (MF) and ultrafiltration (UF) membranes were tested in order to study the effect of the membrane type on the hybrid system performances. Additionally, membrane resistance analyses were conducted in order to understand the membrane fouling mechanism. Two different coagulants were used: Al 2 (SO 4 ) 3 (Alum) and Amerfloc445. The influence of the coagulation conditions including coagulant nature and shear rate and duration on the UF behavior was studied. Indeed, a procedure of flocs breakage-reformation under different shear intensities was followed in the coagulation step, during these tests, flocs size and sensitivity to breakage as well as their regrowth ability were examined. The filtration results indicated that the coagulation step did not enhance the MF performances. The coagulation/ultrafiltration system was found to be better not only in term of permeate quality but also in fouling minimization. Although, Amerfloc445 generated the largest flocs with the best regrowth ability, but these flocs were more sensitive in increasing shear rate. As a result, the flocs breakage dropped the UF normalized flux by at least 22% with Amerfloc445 against a maximum of almost 12% with Alum. The extension of the shear duration from 5 min to 10 min affected the UF behavior especially in the presence of Amerfloc445; indeed the normalized flux decrease reached 14% against just 3% for pre-coagulated effluent with Alum.
