Liposomes are lipid-water systems that can carry hydrophobic and hydrophilic materials because of their amphiphilic structures. Application of liposomes in dyeing and finishing textiles is a new technology based on targeting and slow release which can lead to dyeing at lower temperature along with energy savings and lower environmental impacts. In this research work, a practical method for dyei...

The natural dyes separated from plants are of gaining interest as substitutes for synthetic dyes in food and cosmetics. Thespesia populnea (T. populnea) is widely grown plant and used in the treatment of various diseases. This study was aimed to separate natural dye from T. populnea bark and analysis of its dyeing property on different fabrics. In this investigation pharmacognostic study was ca...

Using nickel electrode as dyeing electrode, sodium carbonate fixing alkali and anodic region region, cotton fabric was electrochemically dyed by reactive blue X-BR under external DC power supply. By comparing the rate, fixation polarization curve evenness of two methods, it can be concluded that electrochemical effect on dye is far better than traditional method.

textile industries use different chemicals in indigo dyeing processes. interest in eco-friendlyprocessing in the textile industry has recently increased because of a larger awareness of environmental issues. for the case of indigo dyeing process, the reducing agent conventionally used is the - environmentally unfavourable – sodium dithionite, which will be replaced in this study with an ecologi...

In this investigation dyeing of alginate fiber was carried out after cationic treatment of 11 EPTAC (2, 3-Epoxypropyl Trimethyl Ammonium Chloride). Optimum dyeing process and 12 parameter show good dyeing performance when alginate fiber dyed with rhubarb dye. In addition 13 to cationic treatment is taken into account for alginate fiber to improve fastness, color strength, 14 breaking strength. ...

1.1 Dyeing auxiliaries Auxiliaries are compounds which are not an integral part of the dyeing process but by adding them to the dye bath the dyeing can be improved. The main functions of auxiliaries are to prepare or improve the substrate in readiness for colorants (by wetting, providing sorption sites, improving or resisting the migration of dyes), to stabilize the application media (by improv...

Many handmade ancient and recent oriental wool carpets show outstanding brilliance and persistence of colour that is not achieved by common industrial dyeing procedures. Anthropologists have suggested the influence of wool fermentation prior to dyeing as key technique to achieve the high dyeing quality. By means of μ-XRF elemental mapping of mordant metals we corroborate this view and show a de...
