Studies on Solvent Dyeing

A Review on the Physico-Chemical Studies of Dyeing Progress and Dyeing Kinetics Using Natural Dyes

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...

Studies on Induction of Erytrocyte Abnormalities in Cirrhinus Mrigala Exposed to Dyeing Industry Effluent

Erythrocyte abnormality test has been used to detect the genotoxic effect of dyeing industry effluent on the fish. The 96h LC50 of effluent against Cirrhinus mrigala was calculated by Finney method and three sublethal concentrations 24.48%, 12.24% and 6.12% were made. Fishes were kept in concentrations and blood was smeared after 24h, 48h, 72h and 96h. Eleven types of erythrocyte abnormalities ...

Effect of Radiation on Textile Dyeing

Thermo acoustical studies on some electrolytic solvent mixtures at 303

Ultrasonic velocity of Benzene with Tolune and O-Xylone with various concentration at 303 K. The internal pressure and some parameters are calculated from the measured sound velocity, density and viscosity. The results were discussed in terms of ion-solvent and solvent-solvent interactions.

Studies on antimicrobial activities of solvent extracts of different spices.

The antimicrobial activities of the ethyl acetate, acetone and methanol extract of 12 plant species were studied. The extract of Capsicum annuum (red pepper) (fruit) Zingiber officinale (ginger) (root), Cuminum cyminum (cumin), Alpinia ficinarum (galingale), Coriandrum sativum (coriander), Cinnamomun zeylanicum Nees (cinnamomun), Origanum onites L. (thyme), Folium sennae (senna), Eugenia caryop...
