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

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, entro

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 tha

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

Renewed interest in textile blends of wool and cotton has led to developments in union dyeing (same shade on both wool and cotton fibers) that has potential for increased markets for both fibers as trans-seasonal apparel. The difficulty of efficiently dyeing wool and cotton to the same shade has limited the availability of yarns and fabrics containing blends of both fibers. In fabrics containing blends of cellulosic cotton and proteinaceous wool, it is generally necessary to employ more than one class of dyes and the process involves several steps with adjustments of pH and temperature.

Abstract:

Textile manufacturing has been one of the highest polluting industrial sectors. It represents about one-fifth of worldwide industrial water pollution. It uses a huge number of chemicals, numerous of which are carcinogenic. The textile industry releases many harmful chemicals, such as heavy metals and formaldehyde, into water streams and soil, as well as toxic gases such as suspended particulate matter and sulphur dioxide to air. These hazardous wastes, may cause diseases and severe problems to human health such as respiratory and heart diseases. Pollution caused by the worldwide textile manufa

There has been growing interest in the dyeing of textiles with natural dyes. The research about the adsorption properties of natural dyes can help to understand their adsorption mechanism and to control their dyeing process. This study is concerned with the kinetics and isotherms of adsorption of lac dyes on wool, silk, and nylon fibers. It was found that the adsorption kinetics of lac dyes on the three fibers followed the pseudosecond-order kinetic model, and the adsorption rate of lac dyes was the fastest for silk and the slowest for wool.

Abstract:

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs of natural dye extraction engendered the discovery of synthetic dyes from petrochemical compounds. Nowadays, they are dominating the textile market, with nearly 8 × 105 tons produced per year due to their wide range of color pigments and consistent coloration. Textile industries consume huge amounts of water in the dyeing processes, making it hard to treat the enormous quantities of this hazardous wastewater. Thus, they have harmful imp

The thermodynamics results show that the up-take of Prodigiosin in PET fiber is linear to the dye bath concentration, with increasing temperature, the distribution coefficient decreases and the thermodynamic affinity of the dye has little gown up, the enthalpy and entropy of
