Extraction approaches of natural dyes for textile coloration

Extraction of Natural Dyes from African Marigold Flower (tagetes Ereecta L) for Textile Coloration

African marigold [Tagetes erecta L.], a major source of carotenoids and Lutin, is grown as a cut flower and a garden flower, in addition to being grown for its medicinal values. Marigold flowers [Tagetes ], which are yellow to orange red in colour, are a rich source of lutein, a carotenoid pigment. Nowadays, Lutein is becoming an increasingly popular active ingredient used in the Food Industry ...

Role of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

Investigation on the capability of Silkworm Pupa as a Natural Adsorbent for Removal of Dyes from Textile Effluent

Recently, use of naturally-occurring low-cost and harmless material for removal of trace contaminants from colored wastewater has attracted extensive attention. In this study, silkworm pupa has been used as a basic dye adsorbent. Adsorption capacity and isotherms have been assessed. Results show that adsorption isotherms can be expressed well by Langmuir equation. The effects of parameters such...

Exploring and exploiting plants extracts as the natural dyes/antimicrobials in textiles processing

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...
