Sustainable Cotton Dyeing in Nonaqueous Medium Applying Protic Ionic Liquids
(2017-10-02)
Dyeing processes are highly important for differentiation of textile products, and in general, they use a huge amount of water and chemical additives, generating a great environmental impact. In the last years, the interest ...
A química e toxicidade dos corantes de cabelo
(Sociedade Brasileira de Química, 2014-07-01)
The market for hair dye involves a growing range of products, which requires greater understanding of hair properties, mechanisms of action and color development. In this work, we present a critical analysis of the ...
Degradation of Acid Blue 40 dye solution and dye house wastewater from textile industry by photo-assisted electrochemical process

Análise da influência da β-ciclodextrina no tingimento de poliamida com corante ácido
(Universidade Tecnológica Federal do ParanáApucaranaBrasilEngenharia TêxtilUTFPR, 2015-11-25)
Dyeing is considered within the textile sector, one of the largest waste generators due to the large consumption of water and chemicals, factors that maximize their pollution potential. In addition to synthetic dyes that ...
Assessment of by-products of chlorination and photoelectrocatalytic chlorination of an azo dye
(Elsevier B.V., 2012-02-29)
The present work describes a more efficient methodology for the chlorination of water containing disperse dyes, where the chlorinated byproducts identified by mass spectra are compared. this investigation, we tested the ...

(John Wiley and Sons Inc., 2018)
Tingimento natural aplicado ao segmento casual chic: uma proposta urbana
(Universidade Tecnológica Federal do ParanáApucaranaBrasilTecnologia em Design de ModaUTFPR, 2017-06-20)
In this work the concept and other facings of natural dyeing are presented, the technique of artisanal origin capable of coloring substrates through dyes extracted from plants, ores and vegetables, beginning in the past ...
Insights into the role of D-A-π-A type pro-aromatic organic dyes with thieno[3,4-b]pyrazine as A acceptor group into dye-sensitized solar-cells. A TD-DFT/periodic DFT study
(Wiley, 2020)
Time-dependent density functional theory (TD-DFT)/periodic DFT calculations were performed to determine the role of pro-aromatic organic D-A-pi-A type dyes (the NL1-NL17 family) with Thieno[3,4-b]pyrazine (Tpy) as A acceptor ...
