“…Fabrics dyed with leaf pigments showed an unchanged or increased colorfastness to light, washing, and storage. is is because the rich content of phenolic hydroxyl within leaf chemical structure is sensitive to light and alkaline condition and can result in a hyperchromic effect [31]. e natural dyes require mordants for their fixation on textile materials.…”

Natural organic fibers such as cotton, linen, and wool are readily attacked by microorganisms. Microbial growth on a textile fabric causes loss of strength and elongation, discoloration, and changes in appearance. The antibacterial finishing agents extracted from nettle plant leaf have been used to impart finish to the cotton fabric by using the Pad-Dry-Cure application method. The antibacterial activity of the finish was assessed quantitatively using the AATCC 100:2004 test method, and the antibacterial activity against Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria was measured. There was a 100 to 99.75 percent reduction in the count of test bacteria. Physical properties of treated and untreated cotton fabrics such as absorbency, fabric stiffness, air permeability, and strength were analyzed. To evaluate the laundering effect of stinging nettle leaf finished fabric, samples were subjected to laundry with 5, 10, 15, 20, 25, 30, 35, and 40 washing cycles using standard AATCC test method 61, and bacterial count of treated samples was tested. The results showed gradual decrease in antibacterial property, with a 100 to 44% reduction in the bacterial count for Staphylococcus aureus and a 100 to 30% reduction in the bacterial count for Escherichia coli. The results of this investigation suggested that nettle leaf, a low-cost abundant plant in Ethiopia, can be used for antibacterial activity in woven cotton fabric.

The discovery of natural local resources for tanning and coloring agents are growing dramatically to sustain a cleaner leather manufacturing technology. Gambir (Uncaria gambir Roxb) has been found potential as tannin and dyestuffs for leather and textile industry. Therefore, to explore these issues, a combination tanning and finishing system were evaluated to observe the efficiency of this extract on leather processing. A combination tanning system based on chrome or glutaraldehyde – gambir and followed by gambir as coloring agent with different concentrations (100 - 200 parts/L) have been applied. In this FTIR (Fourier-transform infrared spectroscopy) analysis of gambir extract showed the presence of phenolic hydroxyl group. Our results revealed that chrome - gambir and glutaraldehyde - gambir finished leather product with 150 parts/L of gambir extract showed excellent rub fastness, color fastness to perspiration and washing. Most of the result values obtained were generally at satisfactory levels which were between 3/4 and 5 fastness values. Visual evaluation reported that chrome-gambir finished leather product with 150 parts/L of gambir extract exhibited better uniformity of colour fastness.

“…With increasing public awareness of eco-safety and health concerns, environmentally friendly and nontoxic bioresource products are gaining popularity in different aspects of our lives (Ebrahimi & Gashti, 2016; Kiumarsi, Gashti, Salehi, & Dayeni, 2017). Natural dyes obtained from insects and plants are renewable and sustainable bioresource products (Gong et al, 2019; Narayanaswamy, Ninge Gowda, & Sudhakar, 2013; Sudhakar & Ninge Gowda, 2011; Willemen, van den Meijdenberg, van Beek, & Derksen, 2018). Bombax malabarica, a member of family Malvaceae, is a lofty, deciduous tree found throughout India and in other parts of tropical and subtropical Asia.…”

The current study deals with the extraction of natural dye from Bombax malabarica flowers, readily available by-product. Dye was extracted under different operating conditions such as time (60–90 min), temperature (90–95 °C), and pH 9. The dyed samples were subjected to CIELAB system using Gretag Macbeth Color Eye 7000A Spectrophotometer for the evaluation of color strength and L*a*b* C and H values. To improve the dye uptake and color fastness, pre and postmordanting was carried out using alum, tannic, and tartaric acid mordants. Dyed silk fabrics were tested for its color fastness when subjected to light, washing, and rubbing. Fastness properties of dyed silk fabric samples were found considerably good. Mordanted silk fabric samples showed increase in dye uptake resulting in high color strength and better fastness properties. The dyed silk samples displayed good antimicrobial activity (reduction rate: 48%) against the bacteria Escherichia coli and (reduction rate: 55%) against Staphylococcus aureus.
