Synthetic dyes are hazardous to the environment and humans due their toxic recalcitrant nature. Hence, present study attempts produce eco-friendly dye from sago industrial waste using S. marcescens SS1. The produced by bacterial bioconversion of was characterized GC-MS obtained 13.423 acquisition time, which is similar standard prodigiosin. effects dyeing parameters were optimized for Jute fabr...

A series of new monoazo disperse dyes containing pyrazolopyrimidine moieties was synthesized by coupling malononitrile or 3-aminocrotononitrile with 4-hydroxy- benzenediazonium chloride. Treatment of the resulting products with hydrazine hydrate yields the corresponding 4-arylazoaminopyrazoles, which then react with either 2,4-pentanedione and enaminonitriles or aryl-substituted enaminoketones ...

The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sod...

A colour ink jet printing with improved water fastness property was produced by using of special component in the ink’s formulation. In this study, the water fastness of ink jet prints which used acrylic/nano-silver resin nano-composite ink instead of conventional resin in ink’s formulation was examined. The nano composite resin was prepared via miniemulsion polymerization of acrylate monomers ...

As an investigative study, the potent bacterium Serratia marcescens SB08 was screened from enteric gut of sulfur butterfly (Kricogonia lyside). Its pigment potential tested, and identified as prodigiosin by structural studies using High Performance Liquid Chromatography (HPLC), Gas Chromatography–Mass Spectroscopy (GC–MS), Fourier Transform Infrared (FTIR) Nuclear Magnetic Resonance (NMR). Vari...

Abstract The dyeing of recycled polyamide nonwoven fabrics based on nanofibers (PA-NWNF), which were fabricated from wastes, was conducted in this study. Since PA-NWNF exhibited a high surface area to volume ratio, it dyed with different particle sizes Disperse Red 167 dye (DR 167, DR 167-B, and 167-C) without auxiliary agents prevent further environmental pollution. undyed PA-NWNF, as well the...

Invasive alien plants that damagingly overgrow native ecosystems can be beneficially used to produce natural dyes. Natural dyes are healthier and more environmentally friendly than synthetic dyes, so their use on textiles other products come into contact with humans is desirable. In this study, the possibility of using a dye extracted from purple petals invasive plant Impatiens glandulifera Roy...

Silk yarns were dyed by using commercial basic, reactive and pre-metallised acid dyes. An aftertreatment with a commercial synthetic tanning agent (syntan) was applied to the dyeings and the aftertreated dyeings were further treated with metal salts in an attempt to improve wash fastness properties. When all samples (untreated, syntanned and syntanned/ backtanned speciments) were subjected five...

<p>Natural products have always been appreciated due to the awareness about environmental standards for global health by using green technologies in their isolation and extraction. Thereupon natural dyes used all fields having ecofriendly, therapeutic aesthetic nature. For current study, microwave radiations (MW) as a extraction tool explore coloring potency of Tea leaves dyeing cotton fa...
