Historical textile dyeing with Genista tinctoria L.: a comprehensive study by UPLC-MS/MS analysis

Textile Dyeing Wastewater Treatment

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...

Genista tinctoria hairy root cultures for selective production of isoliquiritigenin.

Hairy root cultures were established after inoculation of Genista tinctoria in vitro shoots with Agrobacterium rhizogenes, strain ATCC 15834. In transformed roots of G. tinctoria grown in Schenk-Hildebrandt medium without growth regulators the biosynthesis of isoflavones, derivatives of genistein and daidzein, and flavones, derivatives of luteolin and apigenin, characteristic for the intact pla...

Effect of Radiation on Textile Dyeing

Application of Cyclodextrins in Textile Dyeing

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...

Pigment extraction from fungus for textile dyeing

The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...
