Abstract:

Reactive dyes containing cationic groups have great potentiality as novel dyes, which can be applicable to one-bath dyeing of wool/acrylic blended fabrics. In this work, four novel heterocyclic reactive dyes containing cationic groups were designed by using m-aminophenyltrimethylammonium salt or N-(2-aminoethyl) pyridinium chloride salt as cationic groups, N, N-diethyl-1,3-benzenediamine as a coupling component, 2-amino-6-methoxybenzothiazole, 2-aminobenzothiazole or 3-amino-5-nitrobenzoisothiazole as diazo components.

This real-time, closed-loop adaptive control yields good reproducibility and uniform shade build-up in a laboratory dyeing machine.

Abstract:

In this research, the influence of dye structure and dyeing temperature on the adsorption of acid dyes onto polyamide 6 knitwear (PA 6) was studied. Three acid dyes with different amounts of sulphonic groups, namely C. I. Acid Red 88, C. I. Acid Red 14, and C. I. Acid Red 18 were used. Dyeing was performed in a Launder-ometer apparatus at 40°C and 60°C, at pH 4. The samples were taken out of the apparatus at different time intervals. The results showed that both dye structure and dyeing temperature affected the adsorption of acid dyes onto PA 6 knitwear. The rate and quantity of adsorption inc

Abstract:

The textile industry is one of the biggest industrial consumers of water especially dye houses which utilize synthetic dyes and other chemicals. Natural dyes are generally environmental friendly and have many advantages over synthetic dyes with respect to production and application. In recent years, there has been an interest in the application of these dyes due to their bio-degradability and higher compatibility with the environment. A review of previous work in the field of applying dyestuffs of natural source as possible textile dyes is given. From an ecological viewpoint, the substitution

Abstract:

The dyeing properties of the polylactic acid (PLA) fiber with four different disperse dyes was studied. In the disperse dyeing process, differential scanning calorimeter (DSC) analysis was applied to test and analyze the changes of the glass-transition and melting temperature of the dyed and pure PLA fiber. The results indicated that not only the structure of the dispersed dyes and the dyeing conditions affected the dyeing performance of PLA fiber, but also the degree of the crystallinity of PLA fiber contributed to the final dyeing results. Moreover, the transformation of such crystallinity d

Abstract:

Dyeing cellulosic fibres with reactive dyes wastes great quantities of salt and water. The objective of this work is to dye cellulosic fibers using colored nanoparticles (CNPs) as an alternative to dyeing with reactive dyes, without salt and without washing off at the end of dyeing. Samples of cotton were dyed by exhaustion with CNPs at medium to dark colours. Build-up of colour compared to samples from previous work is given and shows a big improvement. Washfastness results are given. Washing-off after dyeing was not necessary for the red and yellow colours. The blue colour needs some washing

Abstract:

Development of dyes with high fixation and salt-free dyeing process for cotton and silk is essential for the textile industry due to ecological and economical reasons. In this study, the synthesis of novel crosslinking polymeric dyes and its salt-free crosslinking dyeing method are described, and cotton and silk have been effectively dyed with the novel dyes. Excellent dye fixation of over 99% on silk and over 97% on cotton, were achieved in a padding process in the salt-free condition. The dyes showed excellent wet fastness values equal to those observed for the standard reactive dyeing.

Abstract:

Modification of polyester fibers for more economical dyeing at lower temperatures without a carrier are considered in this study. Polyester dyeing is carried out industrially under rigorous conditions at high temperatures and under increased air pressure, and are treated with various solvents (primary alcohols) to make the fibers more permeable. As a result, the sorption properties, as well as the disperse dye dyeing ability, are improved. Dyeing of a modified polyester fabric at lower temperatures yielded better results than the standard dyeing of the unmodified polyester under the same condi

Abstract:

Ultrasound energy could strengthen the adsorption of dyes on fiber. The acceleration efficiency of ultrasound was investigated by dyeing cotton with reactive dyes. The experimental findings showed the accelerative efficiency of ultrasound decreased with the prolongation of dyeing time and increment of dyeing temperature. Ultrasound exhibited a better acceleration effect in high dye concentration. The use of ultrasound reduced about 27.2% Remazol red RGB and 50.3% Remazol yellow 3RS in dyeing wastewater.
