In this study, we explore the dyeing properties of extract sappan wood natural dye for coloration wool yarn to find potential use dyed in development eco-friendly textiles. Different characterizations were used know chemistry and its interaction with metal salts wool. Interestingly, found that salts, which are called as mordants reference unmordanted sample, play an important role fixing molecu...

The reaction of the thiomorpholine-4-carbonitrile and piperazine-1,4-dicarbonitrile ligands afforded four Ag(i) coordination polymers with excellent photocatalytic activity in degradation mordant blue 9 dye.

It is felt very essential to develop a knowledge base on dye chemistry and effects of dyeing process variables as well as rate of dyeing and chemical kinetics of dyeing for different natural dyes and fibres combinations to manipulate the processes of natural dyeing efficiently in order to get maximum color yield in economical way. A review on the effects of dye extraction medium, optimum concen...

Major use Preserving wood and anatomical specimens; embalming; browning and etching steel and iron; intensifier in photography; white reserve in fabric printing; tanning leather; depolarizer for dry batteries; electroplating aluminum; mordant for rabbit and beaver furs; manufacturing of ink for mercurography; reagent in analytical chemistry; manufacturing of other Hg compounds; for freeing gold...

Coastal bermudagrass hay was labeled with Cr by the Cr-mordant procedure and with 177Lu applied to the same fiber. Neutral detergent fiber prepared from the same Coastal bermudagrass hay was labeled with Yb, 169Yb, Tb and 160Tb by soaking overnight following by thorough washing and drying. Wood chips were similarly labeled with Sm or La, and Solka Floc was labeled with 147Nd and 141Ce. The carr...

Exponentially growing cells of Bacillus subtilis and Escherichia coli were Gram stained with potassium trichloro(eta 2-ethylene)platinum(II) (TPt) in place of the usual KI-I2 mordant. This electron-dense probe allowed the staining mechanism to be followed and compared with cellular perturbations throughout the staining process. A crystal violet (CV)-TPt chemical complex was formed within the ce...

Using dual-wavelength spectrometry, we have refined the mordant-based bilirubin slide method (Clin Chem 28:2366-2372, 1982) to co-detect unconjugated bilirubin (Bu) and its sugar conjugates (Bc) in 10 microL of serum. The assay is based on three principles: (a) mono- and diconjugated bilirubins behave spectrally like one fraction (Bc) when bound to the mordant, (b) Bu and Bc are spectrally dist...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

Today’s generation is becoming more environmentally conscious and shifting towards sustainable fashion. Unfortunately, synthetic dye being dominantly used as they produce bright color are cheap but hazardous to health compared natural chemical free, biodegradable eco-friendly. Role of has been increased preservation traditional heritage also one the important development goals which every count...
