Electrostatic self‐assembly dyeing of cotton fabrics

Abstract

A new approach to the dyeing of cotton fabrics using an electrostatic self-assembly method was evaluated. Cotton fabrics were pretreated with 2,3-epoxypropyltrimethylammonuium chloride and cationic charges were produced on the fabric surfaces. For the dyeing of cotton fabric, reactive and acid dyes were used. Oppositely charged anionic reactive ⁄ acid dyes and cationic poly(diallyldimethylammonium chloride) were alternately deposited on the surface of cationised cotton fabrics. Ten multilayer films of dye ⁄ poly(diallyldimethylammonium chloride) were deposited on the cotton fabric surfaces using a padder. The build-up of the multilayer films and the level of colour strength (K ⁄ S) achieved are discussed. Samples of cotton fabrics were also dyed with the same dyes, but using the exhaust method, and both types of dyed samples were compared. The washing, rubbing and light fastness properties were evaluated for the dyed fabrics.

Integrating high electrical conductivity and photocatalytic activity in cotton fabric by cationizing for enriched coating of negatively charged graphene oxide

“…However, during any impregnating technique, the surface of the cotton fabric carries a very important role in deciding the type and effect of interaction between the fabric and dissolution or suspension particles. Pretreatment of cotton fabric with cationic agents has been reported to enhance the uptake of anionic dyes in the textile dyeing industry by changing the surface characteristics of cotton fabric (Ugur & Sarıış ık, 2011 Cationic agents react with cotton to impart cationic sites on cotton fabric by forming ether linkages with cellulosic fibers; the resultant is a cationized cotton fabric (CCF) carrying positive surface charge (El-Molla, Badawy, AbdEl-Aal, El-Bayaa, & El-Shaimaa, 2011). However, no efforts seem to have been made to study the effect of cationization on the adsorption interaction of Graphene oxide (GO) sheets on the surface of cotton fabric as both (cotton fabric and GO) show a negative surface charge in aqueous solution.…”

Deposition of nanoparticle multilayers to improve mechanical properties of denim fabrics

“…In our previous studies, we investigated the possibility of nanoparticle film deposition on cotton fabrics with electrostatic self-assembly deposition and we showed that the electrostatic self-assembly process could be used to obtain functional textiles with various nanoparticles (Uğur, 2010;Uğur & Sarıışık, 2011;, 2011a, 2011bUğur, Sarıışık, Aktaş, Uçar, & Erden, 2010).…”

Sustainable Dyeing and Finishing of Cotton Fabrics with Layer-by-Layer Technique

“…Regarding the dyeing processes of textiles with LbL, a few papers have been published. Cotton fabrics dyed with brightening agents [31], reactive dyes and acid dyes [32] have been studied in the literature via the LbL method. In some other studies, the LbL process is used as a pretreatment before dyeing to prevent dye aggregation and to increase dye uptake for cotton [33] and polyester fibers [24].…”
