“…The formation of a covalent bond between the hydroxyl group of triclosan and chlorine of the triazine ring resulted in the development of an ether linkage (C-O-C). Therefore, the absence of a sharp and strong peak at 1046 cm −1 in the spectrum of the unmodified dye and the appearance of this peak in the spectrum of the modified dye confirmed that the modification of the dye with an antibacterial agent was successfully achieved [25,26].…”

The objectives of the present study were to develop an environmentally friendly, low-price, easy, and fast method for developing antipathogenic (antibacterial, antifungal, and antiviral) cuprous-oxide-coated multifunctional fabrics. The fabrics were first sensitized with citric acid, and then Cu2O particles were formed using the Fehling solution method. The cuprous oxide particles were then applied to the cotton fabrics. To create the Cu2O particles, three different kinds of reducing agents with varying concentrations were used. SEM, dynamic light scattering, FTIR, EDS, and XRD were used to examine the surface morphologies and metal presences. In the second step, a reactive antibacterial dye was made (by reacting Reactive Blue 4 with triclosan). The molecular structure of the modified dye was confirmed with FTIR. The resultant antibacterial dye was applied on the copper-treated cotton fabrics in accordance with the exhaust dyeing protocol. The dyed fabrics were characterized through the colorimetric data (L*, a*, b*, C, H, and K/S), levelness of dye, fastness properties as well as exhaustion and fixation rates. Cuprous-oxide-coated fabrics were tested for antipathogenic activity using quantitative and qualitative measurement results. The fabrics treated with cuprous oxide particles reduced with sodium hydrosulfite at 1 g/L seemed to have the highest antipathogenic effect. Moreover, the versatility of the hygienically developed bioactive fabrics in terms of their comfort properties such as air permeability and stiffness were investigated. Finally, the coating’s durability was confirmed by evaluating its antibacterial properties and performing an SEM analysis after laundry.

The chemical‐shift tensor provides an exquisitely sensitive measure of the electronic environment around a nucleus. The tensor is defined by a real symmetric 3 × 3 matrix with six measurable components. Single crystals are usually required to measure all six components whereas three shifts per nucleus are measurable in powders. These powder data, known as principal values , are defined as δ 11 ≥ δ 22 ≥ δ 33 . Presently, most 2D experiments measuring tensor data display the 1D isotropic spectrum along one axis and the tensor patterns for each resonance along the second dimension. Experiments most frequently used are two‐dimensional phase‐adjusted spinning sideband (2D PASS), phase corrected magic angle turning (PHORMAT), FIREMAT (five π replicated magic angle turning), RAI (recoupling of anistropic information), SUPER (separation of undistorted powder patterns by effortless recoupling), and CSA (chemical shift anisotropy) amplification. Very few simple relationships exist between principal values and structure, thus comparison with model structures from computational methods has become important. Recently, these computational methods have been used to predict structure in solids that are intractable to traditional methods. Tensor data have also been found to be extremely sensitive to crystal structure and can therefore be used to further refine some structures, including single crystal structures. The prospect of predicting entire crystal structures from 13 C tensor data and computational methods is now realistic, and a few structures have recently been determined without diffraction data.
