Cold pad–batch bleaching of cotton fabrics with a TAED/H2O2 activating system

Abstract: The cold pad–batch bleaching of cotton fabrics using a tetra acetyl ethylene diamine/hydrogen peroxide (TAED/H2O2) activating system is investigated in this study. The effects of key bleaching parameters (hydrogen peroxide dosage, sodium hydroxide dosage, TAED/H2O2 mol ratio and batch time) on the bleaching efficiency were investigated by single‐factor analysis and orthogonal experiment analysis. The performance of the activator TAED in the cold pad–batch process was examined and the activating mechanism is di… Show more

“…The most common peracid bleach activator currently used is tetraacetylethylenediamine (TAED) (cf. Scheme 1a), which is cost-effective, relatively environmentally benign and provides effective bleaching at temperatures as low as 40 ° C (Shao et al 2010). The second most commonly used bleach activator is nonanoyloxybenzene sulphonate (NOBS) with higher water solubility (cf.…”

“…It has been reported [9][10][11][12] that TAED and NOBS are anionic bleach activators, which have certain limitations due to the negative charge (zeta potential) on cellulosic fibers in water. On the other hand, cationic bleach activators have the potential to exhibit inherent substantivity for the fiber, while simultaneously activating peroxide.…”

“…Tetraacetylethylenediamine (TAED) and nonanoyloxybenzene sulphonate (NOBS) are well-known H 2 O 2 bleaching system activators that lower the bleaching temperature [4][5][6][7]. Some attempts have been made to investigate new compounds as activators for H 2 O 2 bleaching systems to lower the bleaching temperature and shorten the reaction time without causing damage to the cellulose fibres.…”
