“…are a good source of phenolic compounds, including anthocyanins (Mertz et al , ; Acosta et al , ; Schulz & Chim, ). These natural red pigments are water soluble and can offer an alternative to synthetic dyes (Cisse et al , ; Yin et al , ; Carvalho et al , ). Anthocyanins also present potential health benefits (Cassidy, ; Ballard & Maróstica, ) and high antioxidant activity, compared with other fruits (Fan‐Chiang & Wrolstad, ).…”

Slices (1.5 mm thick) of green papaya were impregnated through osmotic dehydration with a blackberry juice-sucrose solution to produce an intermediate moisture product. The effect of processing temperature (T) and sucrose-added molality (m sucrose ) on mass transfer during the operation was assessed, using a response surface methodology (RSM). The RSM was used to model water loss, sugar and anthocyanin gain during the process. Increasing sucrose molality resulted in increasing water loss and sugar gain, but decreasing anthocyanin gain. Water transfer therefore limits anthocyanin impregnation, but not sucrose incorporation. Afterwards, the impact of heat treatment at high temperatures was analysed, using numerical simulation. The conditions of the combined process, designed to achieve an anthocyanin-rich final product, are low sucrose-added molalities (sucrose molality < 1 mol kg -1 ) and high processing temperatures (T > 50°C) for osmotic dehydration, coupled with high-temperature, short-time (HTST) heat treatments for product stabilisation.

“…Contact time in natural dyeing is very important because only dyeing for leveled time gives maximum diffusion of colorant into silk fibers. Low contact time does not favor the even diffusion whereas for long time contact, the overheating after US treatment for 65 min to extract may degrade the colorant . Upon dyeing, the actual colorant did not get significant chance to sorbs onto irradiated silk fabric.…”

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

“…However, to date only indigo is used to dye natural fibres such as cotton, wool and latex. [17][18][19][20] There are few reports of the application of indigo for dyeing synthetic fibres. [21][22][23] There are many polar groups in the molecular structure of nylon, which is thus fit to be dyed by multiple dyestuffs.…”

Nylon 6 was treated with a dielectric barrier discharge, i.e. atmospheric plasma at ordinary air pressure. Factors influencing the dyeing process of nylon 6 using indigo blue powder were studied. The mechanism and effect of this dyeing technology were compared with those of conventional technology. Dyeing after plasma treatment at 30–50 °C can produce high dye uptake in a short time. Notably, dyeing after plasma treatment is beneficial for energy conservation. However, at 60–70 °C, the K/S values of plasma‐treatment dyeing sharply increased over a short time, after which they remained largely unchanged. This finding indicated that the dyeing mechanism changed. The speed constant of dyeing after plasma treatment is 2.8 times that of conventional dyeing. The K/S values of dyeing samples after plasma treatment approached the dyeing saturation K/S value in a short time; therefore, this method of dyeing after plasma treatment achieves energy conservation and efficiency in a brief period of time. Conversely, conventional dyeing is more effective at high temperatures but consumes more energy. The adaptive electro‐discharge condition is achieved under the treatment conditions of 375 W for 2 min. The chromatic aberration of the dyed samples after plasma treatment is smaller than that of conventional dyeing at 50 °C for 75 min.
