Cotton fabric was dyed with Liyuan Blue FL-RN reactive dye. The dye exhaustion and fixation percentages were calculated for all light, medium and dark shades. The dye shows very good exhaustion and fixation properties. Dyed samples were tested for light fastness property as per international standards. The results indicates the dye has a good light fastness property. The effect of UV absorber was studied in order to improve light fastness property. Cationic UV absorber CANFIX SUN was applied on the dyed cotton fabric by exhaust method. The results show that the color depth was similar after UV absorber treatment. In all the cases the use of UV absorber improved the light fastness of dyed fabrics as compared to untreated dyed samples.

Bleached cotton fabric was chemically modified (cationized)with natural amino acids extract obtained by acid hydrolysis (6N HCL) from soya bean seed waste, adding MgCl2 as an acid donor in the pad-dry-calendaring process to investigate the changes in textile properties and its dyeability with reactive dye in both a conventional alkaline dye bath and salt-free acidic dye bath. This modified cotton incorporates new functional groups producing [Formula: see text] in acid bath to obtain cationized cotton, rendering it to eco-friendly salt-free reactive dyeing at acceptable shade depth without much sacrifice of other textile-related properties. Bi-functional high exhaustion-type reactive dye shows better dye uptake than mono-functional cold brand as well as hot brand reactive dye. Moreover, the application of a specific dye fixing agent further improves surface color depth ( K/ S) of the soya-modified cotton fabric. The study of surface morphology of said chemically modified cotton substrate indicates a higher degree of surface deposition, that is, more anchorage of soya extracted amino acids on cotton fabric. Chemical anchorage as per the reaction scheme postulated for such modifications is verified with Fourier transform infrared spectroscopy. Finally, it is revealed that cotton treated with soya extract provides a new route of eco-friendly salt-free reactive dyeing with high exhaustion-type reactive dyes showing much higher dye uptake than the control cotton fabric.

Ft Raman

FT-Raman spectra were obtained from undyed poplin cotton fabric and from the same fabric differently dyed with a bi-functional reactive dye, Cibacron C (molecular structure unknown); the four series of the dyed samples each contained the dye in a different form—unfixed, ammonia-treated/unfixed, fixed, and ammonia-treated/fixed. The spectra were dominated by the dye, but the different states of the dye were not obviously differentiated. Application of principal component analysis showed that the spectral groups of the four different dye states can be discriminated from each other and from that of the undyed cotton. Further, for each series of the dyed fabrics, which contain samples with different amounts of dye, the individual dye concentration subgroups are distinguished. Exploratory quantitative studies suggested that FT-Raman spectroscopy may be a suitable quantitative method for the prediction of % concentration of the unfixed dye on cotton fabrics. A comparison of the FT-Raman results with those from a parallel FT-IR study reported elsewhere indicated that similar qualitative conclusions may be reached with both techniques. However, the FT-Raman approach does provide additional information from the dominating dye spectrum. A comparison of prediction of % concentration of the unfixed dye on the fabric indicated that better partial least-squares (PLS) calibration models may be obtained from the FT-Raman data, but the validation results from a small set of samples suggested only a marginal advantage with the use of the Raman approach.

This work aims to utilize selenium nanoparticles (Se-NPs) as a novel dyestuff, which endows wool fibers with an orange color because of their localized surface plasmon resonance. The color characteristics of dyed fibers were evaluated and analyzed. The color depth of the dyed fabrics under study was increased with the increase in Se content and dyeing temperature. The colored wool fabrics were characterized using scanning electron microscopy (SEM), energy dispersive spectroscopy (EDX) and an X-ray diffraction (XRD) analysis. The results indicated that spherical Se-NPs with a spherical shape were consistently deposited onto the surface of wool fibers with good distribution. In addition, the influence of high temperature on the color characteristics and imparted functionalities of the dyed fabrics were also investigated. The obtained results showed that the proposed dyeing process is highly durable to washing after 10 cycles of washes, and the acquired functionalities, mainly antimicrobial activity and UV-blocking properties, were only marginally affected, maintaining an excellent fastness property.

In this study, we analysed different resin finishing agents on cotton fabric dyed with reactive dye. Different tests were carried out on the resin treated fabric, such as the wrinkle recovery, tensile strength, dimensional stability, stiffness, abrasion resistance and colour strength (K/S) of the dyed fabrics. Melamine formaldehyde resin treated fabric gave a higher crease recovery angle, better smoothness and higher bending length because of higher crosslinking with cellulose. The colour strength decreased after applying the resin finish, and fastness properties were unaffected by the resin treatments.

The objective of this paper was to study the application of Monochlorotriazine-β-cyclodextrin (MCT-β-CD) on cotton fabric and its influence on dyeing and fastness properties of the hot-dyeing reactive dye (with MCT reactive group), Drimarene Red X-6BN, on cotton. The optimum curing condition for MCT-β-CD on cotton was investigated. MCT-β-CD treatment was found to be unaffected on the dyeing properties of the dye on cotton. The color fastness to washing of the dyed fabric was improved in the presence of MCT-β-CD, while the light fastness was unaffected.

Cotton fabric was directly inkjet printed with reactive dye ink, the ink would appear on the permeability of the fabric, the depth of color yield is low, light fastness is poor. Pretreatment agents with different mass fractions had been used to do the pretreatment of the cotton fabric before ink-jet printing, the results showed that: when the concentration of alginate ester or seaweed was between 1.0% -1.5%, the fabrics had the high color yield and the fixation color rate of the dye was the highest. When the amount of NaHCO3 was 3%, the inkjet printing effect of cotton fabrics was the best; color fastness of colors was all good. After Inkjet printing, the best effect can be achieved by steaming the cotton fabrics under the 100 °Csaturated water vapor for 25min: the colors of black, red and yellow of the K / S value were of the maximum, color fastness was fine.

AbstractThe conventional dyeing process requires a substantial amount of auxiliaries and water, which leaches hazardous colored effluents to the environment. Herein, a newly developed sustainable spray dyeing system has been proposed for cotton fabric in the presence of reactive dyes, which has the potential to minimize the textile dyeing industries environmental impact in terms of water consumption and save significant energy. The results suggest that fresh dye solution can be mixed with an alkali solution before spray dyeing to avoid the reactive dye hydrolysis phenomenon. After that, drying at 60–100 °C, wet fixation treating for 1–6 min, and combined treatments (wet fixation + drying) were sequentially investigated and then dye fixation percentages were around 63–65%, 52–70%, and above 80%, respectively. Following this, fixation conditions were optimized using L16 orthogonal designs, including wet fixation time, temperature, dye concentration, and pH with four levels where the “larger-the-better” function was selected to maximize the dye fixation rate. Additionally, the color uniformity and wash and rubbing fastnesses were at an acceptable level when both treatments were applied. Finally, the dyes were hydrolyzed after wet fixation, and the hydrolysis percentages were enhanced after the drying process.
