Dyeing of woven polyester fabric with curcumin: effect of dye concentrations and surface pre‐activation using air atmospheric plasma and ultraviolet excimer treatment

Abstract

Dyeing of polyester fabric with curcumin was studied at 90 and 130°C without and with a prior surface activation of polyester fabric using two different ecotechnologies: air atmospheric plasma treatment and ultraviolet excimer lamp at 172 nm. Without surface activation, dyeing with curcumin followed classical disperse dye behaviour, with higher dye uptake at 130°C than at 90°C, and saturation was readily reached at 2% dye owf at 130°C with a colour yield of 22. Surface-sorbed curcumin molecules extracted with ethanol seemed to increase the colour yield values at 90°C dyeing, while at 130°C they decreased the colour yield values. When dyeing was carried out after a prior surface activation of the polyester fabrics, increased colour yield was observed at both dyeing temperatures for the ultraviolet excimer lamp only (with colour yield increasing from 2 to 10 at 90°C and from 22 to 28 at 130°C for a 2% dye owf). Indeed, both surface activation methods yielded hydrophilic species at the polyester fabric fibre surface, which were confirmed by water contact angle, X-ray photoelectron spectroscopy measurements and atomic force microscopy. However, the surface of the polyester fabric activated using plasma lost all of its hydrophilic species, reaching the water contact angle of untreated polyester when subjected to the dyeing conditions. The excimer treatment yields hydrophilic species that are more resistant to high temperature and pressure dyeing.

Plasma Treatment in Textile Industry

“…It was observed an increase in colour yield for the ultraviolet excimer lamp only because the surface of PET activated by plasma lost all the hydrophilic species when subjected to the dyeing conditions. The excimer treatment yields hydrophilic species that are more resistant to high temperature and pressure dyeing …”

Presenting a New Standard Drug Model for Turmeric and Its Prized Extract, Curcumin

“…Turmeric is a spice used for thousands of years in Indo-Asian culinary recipes, a significant component of most curry powders [ 1 , 2 ]. The bright orange-yellow powder that is derived from the boiled, dried, and crushed turmeric rhizome is also used as a potent natural dye and food colouring agent even today [ 3 , 4 ]. Various parts of the turmeric plant have been used as medicinal treatment for various conditions from ulcers [ 5 ] and arthritis [ 6 ] to cardiovascular disease [ 7 ] and neuroinflammation [ 8 ].…”

Plasma technology in fashion and textiles

“…The dyeing properties of fibers treated with plasma are correlated with the surface chemical composition and surface modifications (Ren et al, 2011;Xiaoliang et al, 2007;El-Nagar et al, 2006;Gawish et al, 2011;Naebe et al, 2009;Motaghi et al, 2009;Ghoranneviss et al, 2011;Fakin et al, 2009;Ke et al, 2008;Barani and Maleki, 2011). However, the increase in dyeability also depends on the exposure time, gas mixture composition, and applied energy (Kerkeni et al, 2012;Yaman et al, 2011;Carneiro et al, 2005Carneiro et al, , 2006Patiño et al, 2011).…”
