“…Due to their good bioactivities and functions [20], the extracts from the byproducts are widely used in the food, food packaging, biomedicine, and cosmetics industries [18,19]. Several researchers have reported the application of bio-colorants derived from grape pomace in the dyeing of textiles [21][22][23]. Grape pomace colorants exhibited good dyeing properties for wool fabric with accepted color-fastness, and the color depth of dyed wool depended greatly on pH and temperature [21].…”

Cotton has the shortcomings of having no antibacterial, antioxidant and ultraviolet (UV) protection properties, which are of great importance for health protection purposes. In the present study, grape seed extract (GSE) mainly composed of proanthocyanins (tannins) was employed to simultaneously import pale colors and the three aforementioned functions to cotton fabric. The tests on the application conditions of GSE showed that pH and GSE concentration had great impact on the color depth of cotton fabric, and the color hue of dyed fabric could be controlled in the absence of pH regulators due to the weakly acidic nature of GSE solution. The fabric dyed with 10%owf (on the weight of fabric) GSE exhibited an excellent inhibition effect towards Escherichia coli, whereas the one dyed with 20%owf GSE had high antioxidant activity of 97%. The fabric dyed with 5%owf GSE offered excellent UV protection. This study reveals that GSE can be used as a functional finishing agent for health protection in cotton textiles in addition to coloration capability.

“…Recently, a great tendency to the use of natural products has been arisen specially when speaking about the coloration of textiles. This renewed interest is mainly due to the increased awareness of the environmental and health risks that synthetic dyes produce in the synthesis, processing and application stages [5][6]. Most of the natural dyes possess low affinity towards the textile fibers, therefore high amounts of the dyeing material and prolonged dyeing times are usually needed to dye a textile product using natural dyeing plants satisfactorily.…”

Despite the vast variety of studies in the field of effect of different mordants on dyeing and fastness properties of wool with natural dyes, there is no thorough investigation on the effect of metal mordants on tensile properties of wool. In this study, five different metallic salts namely aluminum potassium sulfate, tin chloride, potassium dichromate, copper sulfate, and ferrous sulfate were applied on wool with concentrations ranging from 1 %owf to 20 %owf. The tenacity of the samples was measured and SPSS software was employed to investigate the effect of different concentrations of various mordants on tensile strength of woolen yarn compared with raw sample. The results showed that aluminum potassium sulfate and ferrous sulfate had no statistically significant effect on the tenacity of the yarns while tin chloride showed the highest inverse effect and lowered the yarn strength significantly. Aluminum potassium sulfate and ferrous sulfate reduced the tenacity for maximum of 4.2 %owf and 4.4 %owf respectively while the tin chloride treated sample was completely destroyed when applying higher than 5 %owf of the mordant.

“…Although the conventional extraction methods are eco‐friendly, however, these methods are time consuming labor intensive and not cost effective . The utilization of new techniques such as ultraviolet , microwave , ultrasonic , plasma , and gamma radiations have given a promising effect in natural dyeing process. Of these tools, ultrasonic radiation is taking as a convenient and energy saving method .…”

Environmental pollution spread due to frequent use of synthetic dyes has compelled the global community to move toward sustainable and eco‐friendly products. The present research has been conducted to investigate the coloring efficacy of Arjun bark (Terminalia arjuna) for silk fabric under the influence of ultrasonic radiation. Extracts have been prepared in different media and extracts and silk fabrics have been irradiated ultrasonically for 15–60 min at 60 °C. Good color strength is obtained, by dyeing irradiated silk for 65 min at 65 °C, when irradiated extract of pH 3 (RE, 30 mL) obtained from powder (6 g) is used in the presence of salt concentration of 3 g/100 mL. Pre‐chemical mordants such as 5% of Al (Aluminum sulphate) and 9% of Fe (iron sulphate) as well as post‐chemical mordants such as 5% Al (Aluminum sulphate) and 3% of Fe (iron sulphate) have improved the color characteristics. The bio‐mordants employed reveal that 9% of pomegranate and turmeric extracts as pre and post bio‐mordants have given excellent coloring characteristics. It is concluded that Arjun bark has a great potential to act as a source of natural colorant for silk dyeing under the influence of ultrasonic radiation. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S331–S339, 2019
