Biosurfactants from urban wastes as auxiliaries for textile dyeing / Piero Savarino in Industrial & engineering chemistry research, Vol. 48 N° 8 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 8 (Avril 2009) . - pp. 3738–3748 Titre : Biosurfactants from urban wastes as auxiliaries for textile dyeing Type de document : texte imprimé Auteurs : Piero Savarino, Auteur ; Enzo Montoneri, Auteur ; Stefano Bottigliengo, Auteur Année de publication : 2009 Article en page(s) : pp. 3738–3748 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Biosurfactants  Urban  wastes  Cellulose  acetate  fabric Résumé : To promote biobased products for the industry, six biosurfactants isolated from green and food urban residues aged under aerobic digestion for 0−60 days were investigated for their potential to perform as auxiliaries for dyeing cellulose acetate fabric with water-insoluble dyes. The experimental plan included investigation of the chemical nature, surface activity, and power to enhance dye solubility in water, as well as dyeing test performed under a variety of experimental conditions presenting a range of challenge levels. For comparison, the same investigation was performed on commercial synthetic surfactants. The investigated biosurfactants exhibited chemical composition and surface activity properties presumably related to their different biomass sources. However, no significant performance differences in textile dyeing were evident among the biosurfactants and between biosurfactants and synthetic surfactants. The results encourage product and process development for exploitation of biomass residues as a source of chemicals to recycle to the industry.
