“…This leads to increase the ion-solvent interaction in ACN which results in the formation of non-ionic complex Accordingly, the molecular size increases and consequently decrease in conductivity is observed. 42,43 Since, the sp values depend mainly on the solvent polarity and the donor (or acceptor) concentration, thus if the solvent polarity and the donor concentration are kept constant, thus sp values should reflect the electron affinity of the acceptors. On the other hand, if the acceptor concentration is kept constant, the sp values should reflect the donor strength or its basicity.…”

A conductometric titration technique has been used to investigate the electron transfer activity of CT molecular complexes formed by arylazopyrimidine and naphthylazopyrimidine derivatives as donors and the organic p-acceptors p-nitroaniline, p-chloroaniline, p-bromoaniline, anthraquinone, picric acid, anitroso-b-naphthol, p-hydroxybenzaldehyde and maleic anhydride. The study was performed at different degree of temperature and in three different polar solvents namely N,N-dimethylformamide (DMF), acetonitrile (ACN) and dimethylsulfoxide (DMSO). The stoichiometric ratios of these complexes were found to be 1:1. The dissociation constant (as M ) values of the formed complexes have been calculated, and the effects of solvents as well as types of electron donors on their conductance s p -values have been examined.

“…As evidenced by the absence of bacterial development under all treated samples, fabrics dyed with prepared colours inhibit bacterial growth. [25,34,52]. Higher inhibition was seen as a result of increased pH values, as evidenced by an increase in diameter.…”

Herein, we aimed to synthesis two new reactive dyes based on derivatives of Aminorodanine as a chromoforic group, as well as to apply the dye and antibacterial activity to the dyed fabric. First, we synthesized 3-amino rhodanine with glutaraldehyde and terephalaldhyde (2: 1 mole) to form compounds A & B respectively. After that we prepared monofunctional monochlorotriazine (MCT) and bifunctional monochlorotiazine sulphatoethyl sulphone (MCT/SES) by first condensation mphenylene diamine sulphonic acid with Cyanuric chloride (1:1 mole) in ice bath then the second condensation takes place with sulfanilic acid or 1-Aminobenzene-4-β-sulfatoethylsulfone (PABSES) (1:1 mole) at room temperature; the pH was maintained at 5-6 by simultaneous addition 2 M sodium carbonate solution to form monofunctional reactive group C and bifunctional reactive group D respectively. Finally, we synthesized dyes by diazotized C and D by adding sodium nitrite (0.01 mol) to appropriate amines (0.01 mole) in concentrated HCl (6 ml) at (0-5 o C) under stirring then coupling with compounds A and B after dissolved them in ethanol with 2 M of sodium carbonate by 2 mol of the diazonium salt with 1 mole of coupler. The reactive dyes bis MCT 1, 2 and Bis MCT/SES 3, 4 are formed. We provided synthesized dyes structures by elemental analysis, IR, and 1 HNMR spectroscopy. These dyes are used in dyeing cotton and wool that show good light fastness, and are excellent for washing, rubbing, and sweating fastness. Also, we measure antibacterial activity for cotton and wool fabrics toward Gramnegative and Gram-positive

“…Titanium dioxide nanoparticles (TiO 2 NPs) impart textile fabrics simultaneously trilateral properties namely, antibacterial, UV protective and self-cleaning properties. Taking into account ever growing consumer demands, the fact that small amount of TiO 2 NPs provides desirable effects as well as simple synthesis and application procedures, it becomes clear why such multifunctional textile materials are of interest for textile industry [37][38][39][40]. The problematic issues are primarily related to the possible degradation of the fabrics treated with photocatalyst TiO 2 NPs and exposed to longer UV irradiation.…”

B leACheD cotton fabrics were pre-treated with Moringa oleifera leaf extract as natural bioactive materials to impart the fabrics dual antibacterial and sun protective properties. The fabrics were the treated with titanium dioxide nanoparticles(TiO 2 NPs) and zinc oxide nanoparticles (ZnONPs) separately with concentration 2wt.% and 1 wt.% respectively in presence of 1,2,3,4-butane tetracarboxlyic acid(BTCA) as non-formaldehyde crosslinking agent by using pad dry cure method. The treated cotton fabrics were evaluated via monitoring morphological changes of the fibers by using scanning electron microscopy and X-ray diffraction, scanning electron microscopy(SEM&EDX), mechanical properties (tensile strength and elongation at break),roughness, ultraviolet protection factor (UPF). In addition, evaluation of antibacterial activity the treated fabrics by using disk inhibition zone. Research output disclosed that the fabrics treated with moringa extract and then with titanium dioxide nanometal oxide powder show the best results.
