Silver nanoparticles (AgNPs) can be of various shapes such as spherical, nanorod, cylindrical, cubic, irregular, etc on textile materials. However, there is a huge scarcity of literature on the mechanisms of different shapes of AgNPs. In this study, 3 sets of fabric samples were prepared by pretreating with sodium hydroxide (NaOH), citric acid, and non-ionic detergent (span-80). To investigate the diverse shape mechanism green synthesized AgNPs by Calendula arvensis leaves, Citrus reticulate peel, and Cucumis sativus peel extracts were incorporated into the fabric samples. The samples were characterized by UV-VIS Spectroscopy, X-ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The UV-VIS spectra confirmed successful AgNP synthesis for Calendula arvensis and Citrus reticulata, but Cucumis sativus failed AgNP synthesis. The AgNPs were incorporated into the treated fabrics by padding and in-situ method. Then the SEM and XRD images were analyzed meticulously to delve into the nanoparticle shape-building mechanism in light of pH, incorporation methods, and crystallography. It was seen, that pH was the core factor in shape diversity. A pH lower than 7.0 produced predominately closed-pack crystals (111) and due to the low pH, the Gibbs free energy (GFE) was weaker and hence resulted in spherical nanoparticles. Again, the pH range from 7.1 to 8.0 produced cubic shapes due to a high number of open-pack crystals (110) and moderate Gibbs free energy (GFE). On the other hand, pH greater than 8.0 provided high Gibbs free energy, which expedited the reaction and led the nanoparticle shapes to anisotropy.

Cotton is one of the most important fibers used in the textile industry. The dyeing of cotton with synthetic anionic dyes consumes large amounts of salt and alkali, which makes it a challenge for the environment. Furthermore, the relatively high percentage of synthetic dyes remaining in the dyebath is a potential threat for the environment and human health. The application of plant-derived natural dyes has recently been considered as a promising approach to overcome this problem. Optimization of the dyeing process and prediction of the values of the color coordinates of dyed textiles have always been among the most pronounced challenges in the textile industry, especially when a mixture of dyes or mordants is used. In this study, alum was used for mordanting of cotton and two natural dyes—namely, weld and madder—were used for the dyeing. The samples were dyed with various combinations of mordant, weld, and madder for the weight of the fabric and statistical analysis revealed that all three mentioned parameters were effective in determining the color coordinates. To determine the best model to predict the color coordinates of cotton fabrics, the regression method and ANN models weighted with back-propagation (BP) and optimization algorithms, such as the genetic algorithm, particle swarm optimization, gray wolf optimization, FMINCON (a built-in function of MATLAB software) and a combination of particle swarm optimization and FMINCON (PSO-FMIN), were employed and compared based on the mean squared error (MSE). The obtained results revealed that using the PSO-FMIN algorithm for ANN weighting led to higher accuracy in the prediction of color coordinates. The MSEs obtained for ANN outputs and the corresponding actual values reached 2.02, 1.68 and 1.39 for the l*, a* and b* coordinates, which were 44%, 23% and 26% better than the result obtained with BP, respectively.

In recent years, it is seen that there have been many publications on natural dyes in literature. In the studies carried out, one or more plants were taken and the color and fastness obtained with them in the presence of different mordants were examined. Beyond that, functionalities such as odor, antibacterial activity, and UV protection that natural dyes impart to the fabric were examined. However, the important thing that the literature needs is to represent also the results related to the industrial scale production since industry shows high interest to be able to use natural dyes. In this study, seven plant dyes have been used for the coloration of polyamide fabric. The studies have been conducted both on an industrial scale and at the laboratory scale. Based on the statistical analyses, four dyes with the highest color strength and fastness properties including catechu, madder, mulberry leaf, and pomegranate peel were selected for more studies on industrial scale. The results confirmed the good color strength and satisfactory fastness properties against repeated washing, rubbing, water, and perspiration for all selected dyes. The samples dyed with those dyes exhibited excellent protection against UV radiation. The results obtained in this study showed the potential of the selected natural dyes in eco-friendly industrial dyeing of nylon fabric with acceptable fastness properties.
