Inspired by the redox reactions in preparation of iron gall ink that has been used Europe since Middle Ages, we developed a technology for forming oil-in-water emulsions, without any surfactants and emulsifiers, homogenizing mixture tannic acid, gallic Fe(D-gluconate)2, natural oil, which are all approved as cosmetic ingredients. Various plant-derived oils, such argan olive sunflower grape seed...

The key to achieving sustainable development lies in reducing waste, valorizing and adopting conscious consumption. This study aimed evaluate the potential of two by-products from cork industry as natural dyes for textiles. Specifically, cork-cooking wastewater expanded black condensate were tested eco-friendly coloring agents dye cotton (both organic with a surface treatment) wool. After dyein...

Dyeing is the process of adding color to textile products like fibers, yarns and fabrics. Dyeing is normally done in a special solution containing dyes and particular chemical material. After dyeing, dye molecules have uncut chemical bond with fiber molecules. The temperature and time controlling are two key factors in dyeing. The main aim of this project is to monitor and control the parameter...

We have continued to make good progress in all the diverse components of our research effort. Closed-loop control of dyeing processes requires real time monitoring of dyebath concentrations. Significant advances have been made in the use of both visible region absorption spectrophotometry, and flow-injection analysis (F.I.A.), for real-time dyebath analysis. Methods were developed for handling ...

ABSTRACT The kinetics and adsorption isotherms of the extremely slow traditional natural exhaust dyeing that takes many hours or days have been studied purposely to find means improving process. cotton silk fabrics using dye extract M. lucida at 50 °C were elucidated with graphs predict reaction orders identify appropriate isotherm model(s). Since is UV active, changes in absorbance used place ...
