Abstract:
The textile industry generates a large amount of byproducts that must be treated before being recycled or disposed of. The treatments to extract the dyeing agents are mandatory, and involve costs and interaction with toxic reagents. A relevant amount of such byproducts are short cotton dyed fibers. Cotton fibers are high-quality cellulosic fibers and can be used as composite reinforcement. In this paper, dyed cotton fibers were used to formulate, obtain and tensile test composite materials. The impact of the presence of dyes was studied and such dyes enhanced the interphase between the matrix and the reinforcement. On the other hand, when a coupling agent was incorporated to the formulation of the composites, the dyes hindered the chemical interactions between the maleic acid and the OH groups of the cellulosic fibers. Nonetheless, the composite materials showed competitive mechanical properties that were better than other natural fiber-reinforced composites and comparable to some glass fiber-based ones. Dyed cotton fibers can be used as reinforcement without further treatment, increasing the value chain of the textile industry and decreasing the chemical treatments necessary to recycle or dispose of dyed textile fibers.

Abstract:
The sorption thermodynamics and kinetics of disperse dyes on polylactic acid (PLA) fibers were investigated. PLA is crucial for a sustainable textile industry. However, the low dye exhaustion limits the textile application of PLA fibers. The basic dyeing parameters have been determined to provide an in-depth understanding of dyeing behavior. The weak sorption affinities were attributed to the weak dye-fiber interaction and favorable chemical potential of dyes in solvent. Enthalpy–entropy compensation effect also played a role in weak sorption. The interplay of dye structure and enthalpy, entropy changes was rationalized using molecular surface area and rotatable bonds. The conformation constraint strategy was proposed to overcome weak sorption affinity problem by lowering the entropy penalty. Temperature dependence of diffusion coefficients was well reproduced using molecular collision based diffusion model. The activation energies of diffusion have been correlated with molecular volumes of dyes.

Abstract:
Natural dyes are environmentally friendly and have become important alternatives to synthetic dyes in some dyeing products. Therefore, better extraction and dyeing techniques need to be developed for the dyeing process of natural dyes. In this work, cotton fabric was dyed using turmeric extraction solution under an ultralow liquor ratio (materials to liquor ratio of 1:5) and ultrasonic-assisted conditions. Dye extraction using different dispersants and pH values has been investigated and three-factor-three–level Box–Behnken design was employed to explore the dyeing conditions. It was found that sodium dodecyl sulfate systems and ultrasonic waves can effective improve the dyeing depth under neutral condition. The K/ S value can reach 2.53 with ultrasonic power of 200 W, dyeing time of 30 min and temperature of 40℃. Scanning electron microscope images showed that the application of ultrasound did not cause obvious fiber damage. The developed technique could be used in the textile industry to make dyeing cotton fibers with natural dyes more sustainable than it is at present.

Abstract:
This paper reports an investigation of dyeing processes of textiles made from a novel 100% bio-based and fully degradable polylactide/poly (hydroxybutyrate-co-hydroxyvalerate) (PLA/PHBV) fiber. The dye exhaustion, depth of shade and fastness, as well as bursting strength of dyed PLA/PHBV fabrics have been evaluated in terms of types and concentration of dyestuff, dyeing bath temperature, duration, liquor ratio and pH value. Finally, the energy cost of the whole dyeing process of the proposed material is calculated and compared with that of polyethylene terephthalate. The experimental results show that an excellent dyeing effect and bursting strength can be achieved by properly applied dyes (e.g. C.I. Disperse Orange 30, Red 74, and Blue 79) under optimal low-dyeing-temperature conditions (100℃, 10 min, pH 5, LR 30:1). In addition, considering the low energy cost during the whole process, PLA/PHBV fibers can be regarded as a promising and environment-friendly material for the textile industry.

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 alkali dosage and dyeing temperature on the uptake of dyes by this mixture were discussed. Also, the dyeing rates, building-up properties and color fastness of reactive dyes were determined. It was found that Everzol ED reactive dyes exhibited good dyeing properties for silk/PLA mixture under weakly alkaline condition in the presence of sodium bicarbonate.

Abstract:
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. The dyeing of chrome pretreated wool and silk have also been monitored. The result shows that better hue was obtained on mordented fiber. Results of bactericidal studies of chrome pretreated fibers revealed that the toxicity of mordented dyes against bacteria is fairly good. Dyeing on wool and silk fibers resulted in yellowish pink to reddish brown colourations having excellent light fastness and washing fastness.

Abstract:
Abstract The concept of ‘environmental awareness’ has recently had a major impact on the textile industry and on the fashion world as well. In this context, the use of natural fibres and the development of natural dyeing processes gradually became important goals of the textile industry. Of all natural textile fibres, hemp is considered to be one of the strongest and most durable. A wide range of natural extracts have been used for natural textile coloration and dyeing. Dyes deriving from natural sources have emerged as an important alternative to synthetic dyes. Ecofriendly, nontoxic, sustainable and renewable natural dyes and pigments have been used for colouring the food substrate, leather, wood, natural fibres and fabrics from the dawn of human history. The purpose of the research is to obtain ecologically coloured fabrics for textiles by using a method of dyeing that relies on natural ingredients extracted from red beet, onion leaves and black tea. The experiments are conducted on three different types of hemp fabrics. This paper presents the results of the studies regarding the dyeing process of hemp fabrics with natural extracts, the colours of the dyed samples inspected with reflectance spectra and the CIE L*a*b* colour space measurements.

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, carcinogenic, and mutagenic effects that generate some imbalances in plant, animal, and human life. Natural dyes of plant and animal origin exhibit very good tolerance to washing, rubbing, and light and are biodegradable and nontoxic; these properties have led to a call for the renewed use of these dyes. Modern analytical techniques (solid-phase extraction, spectrophotometry, HPLC, HPTLC, capillary electrophoresis) with different spectroscopy (UV-Vis, diode-array detection, pulsed amperometric detection) and/or MS/tandem mass spectrometry detectors have an important role in the textile industry in obtaining essential information about dyeing techniques, material origin, historical trade routes of ancient textiles, and environmental pollution. For this purpose, isolation, separation, and quantification methods of natural and synthetic textile dyes from various matrices (ancient and modern fabrics, water, biota, etc.) are presented.

Abstract:
PurposeThe paper aims to investigate the feasibility of developing natural dyes from the barks of Araucaria columnaris and leaves of Macaranga peltata, Averrhoa bilimbi. The paper also deals with the application of natural dyes in textile coloration.Design/methodology/approachDye extraction was carried out using the aqueous method. The dyeability of the aqueous extract was assessed on cotton, silk and polyester yarns using different mordants (alum, acetic acid, CuSO4, lemon juice) and without mordant. UV–Visible spectral analysis and pH of different natural dyes were determined. Percent absorption, K/S values, CIELab values and fastness properties of the selected dyed yarns were also assessed.FindingsThe percentage values for dye exhaustion differed with various mordants. The K/S values were found to be influenced by the addition of mordants. Different hues were obtained with the usage of different mordants. Fastness results exhibited good to very good grades.Research limitations/implicationsThe effective application of aqueous method of dye extraction in the study avoids solvent toxicity. The current results proved that the dyeing could be achieved at room temperature for different yarns (cotton, silk, polyester). At present, no report exists in the literature of research work on the extraction of natural dyes from the leaves of M. peltata, A. bilimbi and their dyeing potential on cotton, silk and polyester.Practical implicationsThe present work offers new environment-friendly dye as well as simple dyeing method. Barks and leaves are promising sources of dye. Enormous availability of barks and leaves avoids the exploitation of the plant parts for the extraction of natural dyes.Originality/valueThe important feature of this study was the effective dyeing of natural and synthetic fibers at room temperature. The novel sources of natural dyes would contribute significantly to the existing knowledge of dyeing, and the natural dyes reduce the environmental impact of synthetic dyes.

Abstract:
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 also transferable to other fibers and dye classes. Using this model, optimum dyeing parameters and dye combinations can be determined from the sorption curves, which are easily obtained by UV-VIS spectrophotometry.
