Abstract:

Vegetable dyes and their uses are known in an cient time more than 2000 years ago. It was found that the discovery of synthetic dyes reduce the use of natural dyes and consequently the export of same was affected in large extent. However due to non toxic nature, eco-friendly behaviour and properties to impart variety of colours once again natural dyes are getting more attention of chemists and dyers. The present paper deals with optimization of dyeing and mordanting of wool and cotton samples with fruit rind of Juglans regia and standardization of ancient dyeing procedure and also the fastness

Three novel vinyl sulfone reactive dyes of various metallic salts (Na, K, Li) have been synthesized by coupling 1-amino-phenyl-4-beta hydroxyethyl sulfone sulfate ester with 1-amino-8-hydroxynaphthalene-3,6-disulfonic acid (H-acid). The reactive dyes were then purified using ultrafiltration (UF). The ultrafiltrated dyes of the various metallic salts were characterized by their spectrophotometrical data using Ultra Violet-visible (UV-vis), Fourier transform infra-red and optical emission spectroscopy, X-ray diffraction, and elemental analysis.

Abstract:

The dyeing properties of lac dyes for wool, silk and nylon fibers were investigated, and compared in terms of dependence of dye uptake on pH, dyeing rates, and building-up performance as well as color hue and color fastness of dyed fabrics. For all the three fibers, the uptake of lac dyes was greatly influenced by pH, indicating that the electrostatic interaction between lac dyes and fibers predominantly contributes to lac adsorption. The maximum adsorption wavelength of dyed fabrics shifted to a higher value with increasing application pH, indicating the existence of bathochromic effect. Lac

Abstract:

The use of natural dyes in the dying process was one of the oldest procedures used by the ancients. Obtaining dyes from natural sources means extracting them from plants and animals. Colors are derived from natural sources. Dyes can be divided into two categories: natural dyes and synthetic dyes. Synthetic dyes include saffron dyes and azo dyes, the latter being one of several types of organic compounds that are produced in large quantities through industrial processes. Dyeing is a process that involves the use of dyes in the dyeing process of textiles and food products. Fabrics are colored wi

Abstract:

A new kind of red polymaleic acid dyes was designed and synthesized through diazotization-coupling reaction of a polymeric coupling component, which was prepared based on poly(maleic anhydride) and 1-amino-8-naphthol-3,6-disulfonic acid (H acid), and was then characterized by FTIR and 13C NMR. The dyes were evaluated on dyeing of cotton. Results showed that cotton dyed with the polymaleic acid dyes possessed high fixation and good fastness properties.

Noble metal nanoparticles and traditional dyes jointly colorate silk fabrics. Gold and silver nanoparticles were in situ synthesized on silk fabrics, and the complex coloration was realized by the integration of traditional dyes into the treated silk. The localized surface plasmon resonance properties of gold and silver nanoparticles were not affected by the coloration of dyed-on silk fabrics. The combined optical properties of nanoparticles and dyes extended the color range and enhanced the color strength (K/S) of silk fabrics.

Commercial acid levelling and acid milling dyes were used. Fastness to light and washing were assessed by standard methods, and samples were exposed to sunlight behind glass for 12 months.

Cytotoxicity in vitro using hepa-1 mouse hepatoma cells for 24 h and 72 h exposure was observed as the highest tolerated dose.

DyPs are a type of heme peroxidase and are quite different from known heme peroxidases in terms of amino acid sequences, protein structure, catalytic residues, and physical and chemical properties. DyPs oxidize polycyclic dyes and phenolic compounds. Thus they find high application potentials in dealing with environmental problems.
