Abstract:

Abstract The textile industry uses many raw materials (natural and synthetic dyes and fibers) and different dyeing techniques that can be considered important pollutants with a negative impact on the environment (toxic working conditions, discharged wastewater, and contamination). Although synthetic dyes are intensively used, offer a wide range of colors and hues and properties of adhesion, longevity, and resistance to sunshine and chemical processes, and are cost-effective, they have begun to be restricted by many textile producers because they are nonbiodegradable and have toxic, carcinogeni

Novel acid azo and mordent acid azo dyes have been prepared by the coupling of diazo solution of different aminonaphthol sulphonic acids and aromatic amino acids with 2,4-dihydroxybenzophenone. The resultant dyes were characterized by elemental analysis as well as IR and1H NMR spectral studies. The UV-visible spectral data have also been discussed in terms of structure property relationship. The dyeing assessments of all the dyes were evaluated on wool and silk textile fibers.

Polyester fibers (PES) are the most consumed textile fibers due to their low water absorption; non-ionic character and high crystallinity. However, due to their chemical structure, the chemical interactions between polyester, finishing products, and dyes are quite challenging. We report on the use of ozone to modify the surface of polyester fibers with the goal of improving the interaction of the modified surface with finishing compounds and dyes. We used C.I.

Dyeing of polyamide fibers is normally made with acid dyes, however, it is somewhat difficult to achieve uniformity and control of pH and temperature must be carefully made. The possibility to dye polyamide 6.6 in a larger gamut of colours with good properties may be achieved using other classes of dyes after plasmatic modifications in textile substrates. Polyamide 6.6 fabrics were treated with Double Barrier Discharge (DBD) plasma obtained at atmospheric conditions in a semi-industrial machine and very positive results were obtained when dyeing is made with direct dyes.

Abstract:

Cotton is one of the most important fibers used in the textile industry. The dyeing of cotton with synthetic anionic dyes consumes large amounts of salt and alkali, which makes it a challenge for the environment. Furthermore, the relatively high percentage of synthetic dyes remaining in the dyebath is a potential threat for the environment and human health. The application of plant-derived natural dyes has recently been considered as a promising approach to overcome this problem.

Increasing reports of coloured effluent from waste water treatment plants receiving reactive dye waste from textile mills indicate the need to learn more about the fate of these dyes. The project concerns the development of analytical techniques for the analysis of reactive dyes in textile waste. An analytical procedure using High Performance Capillary Electrophoresis (HPCE) and High Performance Liquid Chromatography (HPLC) for the separation of a range of reactive dyes in textile waste water is described. The dyes belong to a range of bis-monochlorotriazinyl dyes used widely in the dyeing of

Abstract:

Silk/PLA mixture is a new textile material, and it combines the outstanding characteristics of silk and PLA fibers. During the wet process, this mixture is subjected to some problems owing to the poor resistance of PLA fiber to alkali. The silk component in this mixture can be dyed with acid dyes under acidic condition, and with reactive dyes under alkaline condition. In the present work, silk/PLA mixture was dyed with Everzol ED reactive dyes in the case of the use of sodium carbonate and sodium bicarbonate as alkalis for the fixation of dyes.

The increasing use of functional aramids in a wide array of applications and the inert nature of aramids against conventional dye and print methods requires developing new dyeing methods. This study aims to use environmentally friendly method with a cationic dye as an alternative for dyeing para-aramid fabrics. Experiments used a multi-factorial design with functions of pretreatment, dye solvent (water and/or glycerol) and auxiliary chemical additives (swelling agent and surfactant) and a sequential experimentation methodology.

Nanocellulose (NCC) has attracted increasing attention for use in several applications owing to its impressive strength-to-weight ratio, ease of functionalization, and apparent biocompatibility. In the nanocomposite textile field, NCC has exhibited outstanding potential for reinforced fibers, especially fibers processed by solution spinning. Continuous NCC fibers with high modulus and strength can be obtained, while preserving the cellulose I crystal structure. Owing to the various possibilities of surface modification, NCC is an efficient adsorbent of cationic and anionic textile dyes, as it

The reactive dyes are mostly (50%) employed for coloration of cellulosic fibers, however they can also be applied on wool and nylon. Unfortunately, they possess a low degree of fixation (50÷90%), since the functional groups also bond to water, creating hydrolysis and the exces

However, the main applications of electrochemical treatments in the textile sector are based on oxidation reactions.

Nonetheless, due to its structure, the use of only disperse dyes for dyeing creates a significant weakness in its coloring. In this paper, the utilization of reactive and acid dyes in the dyeing of polyester after chemical modification with guanidine-based polymer is investigated. The dyeing of poly(ethylene terephthalate) (PET) fabrics with reactive and acid dyes was succeeded via modification with guanidine-based polymer.

Dye uptake of textile substrates can be described as time-dependent by a new mathematical model, in which the sorption process is divided into fast and slow subprocesses. The fast subprocess describes the adsorption of the dye onto the fiber surface, and the slow one details the diffusion of the dye into the fiber. In addition, dye desorption is simultaneously considered along with adsorption. Relating this concept to the dyeing process, it is possible to divide the process into two parts—dye adsorption and diffusion. The model is verified by dyeing cotton with direct dyes, but the results are
