“…Then, the penetration of the cationic part into the cell wall and the destructive interaction with the cytoplasmic membrane, lead to the leakage of intracellular components and, consequently, to the cell death [6][7][8]. http Polyacrylonitrile (PAN) is one of the polymeric materials widely used in industry due to its well-known properties as resistant to most solvents and chemicals, slow to burn, low permeability to gases and so forth [9][10][11][12][13]. In the last years, PAN copolymers have evolved a large variety of products based on blends, ultrathin membranes, precursors of carbon fibers, and nanofibers by electrospinning [14][15][16].…”

“…10 To eliminate the environmental impact, works have been done on dyeing cotton at a neutral pH condition 11−13 or by low add-on technology controlling the wet-pick up. 14 Novel methods, such as chemical grafting of the disperse dye onto polyacrylonitrile, 15 dyeing of nylon 6 with extracted natural dyes from waste leaves, 16 computational and experimental assessment on corona discharge surface ionization of poly(ethylene terephthalate) (PET), 17 and dyeing of PET with various nanosilica particles, 18 have also been investigated.…”

Effects of hardness and the pH value of water in a water pool on PEG-based nonionic surfactant dyeing of cotton fiber with reactive dyes in a heptane reverse micelle system were investigated in terms of the color yield, reflectance, CIE L * a * b * value, and unlevelness. Results reveal that the effect of the water-pool pH value on the color yield and reflectance are more significant than the effect of hardness in the water pool. The dyed fabrics under an alkaline water-pool condition obtain a lower color yield and higher reflectance percentage than those under acidic and nearly neutral conditions. The increase of hardness in a water pool has higher influence on unlevelness of dyed samples than the increase or decrease of the pH value in a water pool. The changes in hardness and the pH value in a water pool did not result in a significant change in CIE L * a * b * values of dyed specimens, and no chromatic change was found in dyed fabrics. Excellent washing fastness results of the dyed fabrics, guaranteeing adequate removal of unfixed dyes, assure accuracy of the results in a spectrophotometric measurement.

“…Reverse micelles are self-assembled colloidal structures formed by non-ionic surfactants in organic solvent with nanoscale water pools in hydrophilic cores [33]. Previous literature on the colorimetric measurement of textiles was achieved using spectrophotometry [34,35,36,37,38]. In our previous studies, we successfully used poly(ethylene glycol) (PEG)-based non-ionic surfactants to facilitate the formation of reverse micelles, the analysis of stability and dispersity of well-defined reverse micelles with different reverse-micellar dyeing parameters, and the application of the computer color-matching (CCM) technique to study the dyeing properties of cotton fiber in different non-aqueous solvent media [39,40,41,42,43,44].…”

A Computer Color-Matching Study of Reverse Micellar Dyeing of Wool with Reactive Dyes

Computer color-matching (CCM) and the levelness of poly(ethylene glycol)-based reverse-micellar dyed wool fabrics in octane and nonane were investigated and compared with a conventional water-based dyeing system. Reflectance curves and calibration curves exhibited no chromatic change and maintained high linearity in both dyeing systems. The linearity of water-dyed calibration curves was slightly higher than that of the reverse-micellar dyed curves. The color yield, in term of K/Ssum values, of solvent-dyed samples was found to be generally higher than that of water-based dyed samples at various calibrated dye concentrations. The concentrations predicted by CCM were close to the theoretical concentrations for both dyeing methods. This indicates that octane- and nonane-assisted reverse-micellar dyeing of wool is able to generate color recipes comparable to the conventional water-based dyeing system. The solvent-dyed samples, measured by the relative unlevelness indices (RUI), exhibit good-to-excellent levelness, which is highly comparable with the water-dyed samples.
