“…Fixation agents helps the fabric to absorb the dye and enhance color retention by molecular bonding process. Dyeing auxiliaries play an important role in the determination of the final dyeing quality dan can assist in achieving outstanding dyeing performance [17]. The Staining and Gray Scales obtained from color fasteness to dry rubbing test on fabric fixated with alum (AI2(SO4)2) were between 3 and 5.…”

Mangroves have many environmental, ecological, economic, health and industrial benefits. One of the applications of mangroves in industry is as a natural dye for textile materials. The aim of the study was to determine the potential application of mangrove extract as a natural dye for batik, to determine the pigment content of the test sample, and to test the fastness of natural color made from leaves and bark of Avicennia marina and Bruguier gymnorrhiza, at plant ages of 5 and 10 years. Sample collection was done by picking leaves and collecting the bark of Avicennia marina and Bruguier gymnorrhiza. Color fastness to detergent washing test, wet and dry rubbing test were carried out with a crockmeter, using the Staining Scale and Gray Scale standards. UV Vis Spectrophotometry Analysis was employed to determine the pigment content. The results showed that leaf and bark extracts of Avicennia marina and Bruguiera gymnorrhiza mangroves have the potential to be applied as natural dyes for batik. Mangrove natural dyes showed scores of 3, 4, and 5 on the fastness tests of dry rubbing, wet rubbing and detergent washing. These findings indicate that the natural dyes in this study have met the Indonesian National Standard, which requires a minimum score of 3.

Polyamide-12/Portland cement nanocomposite was prepared by using the exfoliated adsorption method. The fabricated nanocomposite was applied first time to remove Congo red (CR), brilliant green (BG), methylene blue (MB), and methyl red (MR) from the synthetic wastewater. The polymer nanocomposite was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, elemental mapping, Brunauer–Emmett–Teller surface area analysis, and X-ray diffraction. The adsorption was rapid and all the studied dyes were absorbed on the surface of the polymer nanocomposite in 90 min. The point of zero charge was found at pH 5 and the factors such as pH, time, and temperature were found to affect the adsorption efficiency. Freundlich isotherm and pseudo-second-order models well-fitted the adsorption isotherm and kinetics data, respectively. The calculated maximum adsorption capacity was 161.63, 148.54, 200.40, and 146.41 mg/g for CR, BG, MB, and MR, respectively. The mode of the adsorption process was endothermic, spontaneous, and physical involving electrostatic attraction. On an industrial scale, the high percentage of desorption and slow decrease in the percentage of adsorption after every five regeneration cycles confirm the potential, practicality, and durability of the nanocomposite as a promising and advanced adsorbent for decolorization of colored wastewater.
