Influence of acetated‐based and bromo‐based ionic liquids treatment on wool dyeing with acid blue 7

Bromo‐based and acetated‐based ionic liquids (ILs), 1‐butyle‐3‐methylimidazolium bromo ([Bmim]Br), 1‐ethyl‐3‐mthylimidazolium bromo ([Emim]Br), 1‐butyle‐3‐methylimidazolium acetate ([Bmim]Ac), and 1‐ethyl‐3‐mthylimidazolium acetate ([Emim]Ac), were synthesized and employed for wool surface treatment. Scanning electron microscope results indicated that the wool surfaces treated with acetated‐based ILs were eroded more than those treated with bromo‐based ILs. Comparable studies showed that the wool samples treated with acetate‐based ILs, especially [Emim]Ac, had higher initial dyeing rate and equilibrium exhaustion than those with bromo‐based ILs. Along with treatment temperature and time increasing, acetate‐based ILs had more remarkable effects on mechanical and dyeing properties of the wool samples than bromo‐based ILs. The wool samples treated with [Emim]Ac at 60°C for 10 min had excellent low‐temperature dyeing properties. The color depth (K/S) investigations showed that the wool samples treated with acetate‐based ILs possessed darker color depth than those treated with the bromo‐based ILs. Color fastnesses of the wool samples treated with [Bmim]Br, [Emim]Br and [Bmim]Ac exhibited the same grades as the untreated sample, while wet color fastnesses of [Emim]Ac treated sample were slightly decreased. © 2011 Wiley Periodicals, Inc.

Mordant dye application on cotton: optimisation and combination with natural dyes

It is well known that cotton fibres can be dyed through the formation of coordinate bonds involving cellulose chains, mordants such as alum, and natural dyes such as alizarin. Similarly, synthetic dyes known as mordant acid dyes can be used to dye wool fibres. Unlike mordant dyes on wool, the fastnesses of natural dyes on cotton are often low. Although concerns surrounding textile sustainability have sparked renewed interest in the use of natural dyes, extensive replacement of synthetic dyes with natural dyes is neither practical nor fundamentally possible. However, similarities in dyeing methods using mordant and natural dyes raise the possibility of using mordant dyes as alternatives to natural dyes in the dyeing of cotton. Further, the potential for combining suitable dyes from these two classes to expand the colour gamut currently available from natural dyes on cotton seem worthy of exploration. The results of this study indicate that shades comparable with those produced by natural dyes can be obtained on cotton using select mordant dyes following Fe²⁺ and Al³⁺ pretreatments. The best results were obtained using a two‐step/two‐bath process and dyes such as CI Mordant Blue 13 and CI Mordant Orange 6. In evaluations of mordant and natural dye combinations using the two mordant dyes logwood and Osage orange as prototypes, interesting fabric shades were obtained. However, the fastness properties of these dyes must be improved in order to produce commercially viable dyeings.

Dyeing fine denier polypropylene fibers with phenylazo- β -naphthol-containing sulfonamide disperse dyes

A series of phenylazo-β-naphthol-containing sulfonamide disperse dyes were prepared from C.I. Acid Orange 7 by successive reactions of chlorination and amination, and their chemical structures were characterized by FTIR, ¹H NMR, and mass spectrometry. The dyes were applied to coloring of knitted fabrics from fine denier polypropylene fibers by exhaust dyeing and their optimal dyeing conditions, such as dyebath pH, dyeing temperature, dyeing time, and dye concentration were investigated in detail. Then, dye exhaustion, color strength, and color fastnesses of the dyes on the fibers were assessed and summarized. In view of dye exhaustion and color strength of the sulfonamide dyes on fine denier PP fabrics, 90°C was selected as the best dyeing temperature at dye concentration below or equal to 3.0% owf. For achieving higher color strength, 130°C was the better choice when the dye concentration was above 3.0% owf. The sulfonamide dyes, especially secondary sulfonamide dyes, exhibited superior dye exhaustion and color fastnesses to washing, sublimation, and rubbing on fine denier PP fabrics in comparison to C.I. Solvent Yellow 14 bearing the same chromophore but without sulfonamide group.
