Global heat, carcinogenic, and viral diseases created due to industrial pollutants has led people shift toward natural products particularly dyes in all walks of life. In this study, U.S. rays up-to 60 min, were used extract the color aqueous medium employed onto silk fabric at selected conditions. It been observed that good strength found when 30 mL acidic ( pH = 4.0) obtained from 6.0 g Harma...

In recent years, chitosan and its different derivatives have been extensively used in surface modification and functional finishing of textiles. In this study, wool yarns used in handmade carpet were treated with different concentrations of chitosan-poly (amidoamine) dendrimer hybrid (Ch-PAMAM) and characterized by scanning electron microscope (SEM), and their dyeing properties were investi...

This study aimed to assess the effectiveness of utilizing a tannin-based natural brown colorant from neem bark for dyeing wool under microwave treatment, specifically evaluating its coloring efficiency. The was extracted in methanol solution that had been acidified both before and after being subjected treatment up 6 min. variables were optimized create new shades dye with desirable fastness pr...

The ongoing age is the time of sustainability, where in current pandemic scenario, which getting worse, needs treatment with nature rather than chemical-based products. In this study, microwaves (M.W. rays) treatments as extraction mode for Esfand ( P. harmala) have been revived polyamide (nylon) dyeing. water solubilized and acid filtrates (nylon fabrics) were treated M.W. rays up to 10 min an...

Interactions of the anionic form of C.I. Mordant Blue 29 with cationic and nonionic surfactants have been studied by absorption spectroscopy. The dye interacts strongly with oppositely charged surfactants in the pre-micellar concentration range with an accompanying change in its spectral properties, while its interaction with the polyoxyethylene group of nonionic surfactants does not have such ...

Treatment of effluents containing phenols such as textile dyes with fungal laccases is usually limited to the acid to neutral pH range and moderate temperatures. Here we demonstrate for the first time that spore-bound laccases which are stable at high temperatures and pH values can be used for phenolic dye decolorisation. Laccase containing spores from Bacillus SF were immobilized on alumina pe...

Natural dye extracted from Caesalpinia sappan Linn. was applied to a cotton fabric and silk yarn by dyeing process. The dyestuff component of Caesalpinia sappan Linn. was extracted using water and ethanol. Analytical studies such as UV–VIS spectrophotometry and gravimetric analysis were performed on the extracts. Brazilein, the major dyestuff component of Caesalpinia sappan Linn. was confirmed ...

Increasing environmental awareness has led to a growing interest in natural dyes the textile dyeing industry as consumers become more aware of toxicity synthetic that are harmful environment and health. Although environmentally friendly compared dyes, general their performance is less than dyes. Typically, metallic mordants used enhance affinity materials, perhaps this process breaks journey gr...

The effect of material type, yarn count, pick density, type of mordant and layers of fabrics on the electromagnetic shielding properties of textile materials has been studied. The shielding effectiveness of the fabric is measured by estimating the insertion loss incurred to the signal when the sample is placed in the path of the signal at the frequency range 100 MHz-3 GHz inside the coaxial tra...
