For this purpose, nanofibers having 7 different morphologies were produced from 4% PVA aqueous solutions. The morphologies of the produced nanofibers were analysed by scanning electron microscopy (SEM). As a result of these analyses, it was observed that uniform nanofiber morphology was formed in nanofiber productions made with distilled water, while in the others, dense bead structure was formed at low voltages and nanofiber morphology with reduced bead amount at high voltages was observed. In all electrospinning experiments, it was observed that the nanofibers were randomly collected on the collector plate. It was observed that the n...

The knitted fabrics were then made from these yarns and subjected to oxygen plasma treatment for 5 min. The samples were dyed with a disperse dye and an acid dye and the color strength, color coordinates, and fastness properties of the dyed samples were compared. The effect of plasma treatment on the surface chemistry and morphology of the samples was evaluated using Fourier-transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM) analyses, respectively. FTIR analysis confirmed the introduction of oxygen-containing groups on the surface of the plasma-treated samples. AFM images confirmed etching of the fibers, and the surface roughness of the fibers increased significantly after plasma treatment. The incorporation of nanoclay in the multifilament yarns improved the dyeability of the polypropylene/nanoclay composite fibers with disperse and acid dyes. The optimum amount of the nanoclay for obtaining the highest color strength was 2 wt% and 1 wt%, for dyeing with the disperse and acid dye, respectively. Plasma treatment enhanced the dyeability and fastness properties of the fibers. The highest K/S values obtained on plasma-treated PP/nanoclay samples were 1.27 and 10.88 for acid and disperse dyes, respectively. The fastness properties of the samples dyed with the acid dye were generally lower than those of dyed with the disperse dye. The highest washing, dry rubbing, and light fastness properties were obtained on plasma-treated and disperse-dyed PP/nanoclay (2 %) sample, which were 4–5, 3, and 5, respectively.

In this study, the microwave-assisted extraction of colorant from cochineal insects for dyeing of bio-mordanted silk has been carried out. Acidic, methanolic, and acidified methanol solubilized media were used to extract the natural colorant from cochineal under microwave irradiation for 1–6 min. Bio-mordants have been employed at optimized conditions to make the process greener and sustainable. It is found that acid solubilized extract of pH 4, employed at 55 °C for 55 min containing 5 g/100 mL of Glauber’s salt as exhausting agent has given high color strength onto microwave-treated silk fabric. Suggested ISO standards for colorfastness have revealed that bio-mordants have given excellent color depth and excellent rating of fastness properties, compared with chemical mordants used. It is found that microwave treatment has not only improved the dyeing behavior of colorant extracted from cochineal in acid solubilized medium but also enhanced the color characteristics onto bio-mordanted silk fabric.

In order to achieve this goal, Rhubarb flower parts were used to produce a brown hue on nylon 6 fabric. The effects of dyeing parameters such as dyeing time, temperature, dyebath pH, M:L, salt addition, dispersing agent, and dye concentration on color strength were investigated. Using 100%owf dye in an acidic medium at boil and the material to liquor ratio of 1:30 for 75 min was determined to be the optimal condition for dyeing nylon 6 with rhubarb flower. In order to achieve acceptable color fastness, four natural mordants were applied, including walnut husks, pistachio hulls, pine cones, and green coffee. Colorimetric measurements revealed that mordanting did not affect the hue of the color compared to the non-mordant sample. In addition, diverse natural mordants produced the same color (i.e., brown) with varying color strengths, of which 10%owf walnut husk generated the strongest color. Bio-mo...

This explains the great amount of research developed in this regard, especially when the dye used was derived from a natural product’s waste. This research aims to evaluate the affinity of the dye extracted from date palm fibrillium to a multifiber fabric. This choice was made to investigate a comparison of the dyeability of many kinds of textile fibers with the obtained colorant from the date palm fibrillium. It was shown that the different types of fibers were well-dyed. The darkest dyes were obtained especially by using wool and nylon fabrics. In view of these results, wool and nylon fibers were selected for developing a dyeing investigation. The effect of the most important operational conditions such as temperature, pH, and dyeing time on the dyeing quality results has been investigated. Color yield (K/S) and CIELab values (L*, ...
