Adsorption properties of direct dyes on viscose/chitin bicomponent fiber: evaluation and comparison with viscose fiber

Abstract

Two direct dyes were applied for dyeing the viscose/chitin bicomponent fiber, whose chitin component can provide functionalities and enhanced dyeing properties.

Valorization of nylon and viscose-rayon textile yarn wastes for fabricating nanocomposite films

“…Recently, viscose-rayon has been gaining much attention as a raw material for green textiles [8]. It is a manmade regenerated cellulosic textile produced from the wet spinning process of natural sources like woods [9,10] that are later converted into yarns. Yarns are further used in textile weaving, hand-knotted carpet weaving, home furnishing, and industrial textile applications [9,10].…”

“…It is a manmade regenerated cellulosic textile produced from the wet spinning process of natural sources like woods [9,10] that are later converted into yarns. Yarns are further used in textile weaving, hand-knotted carpet weaving, home furnishing, and industrial textile applications [9,10]. In the textile weaving processes, a huge amount of cut viscose-rayon yarns waste is generated [11,12], which is either incinerated or landfilled [1,13].…”

Construction of a polyoxometalate-based magnetic composite MOF for the effective adsorption of cationic dyes

“…With the rapid economic development, dye pollution has become a serious social problem because it is harmful to the water environment and human health. 1 In order to remove the contamination of dyes, different kinds of physical, 2 chemical, 3 biological, 4 and integrated technologies have been developed. 5,6 Among the various dye treatment methods, the adsorption technique shows unique advantages.…”

Removal characteristics of two anionic dyes by a polyethylenimine/poly(N,N-dimethylaminoethyl methacrylate) gel

“…When these chemicals are treated by adsorption, relatively ideal processing speed, high efficiency, and easy operation can be realized, while no extra chemicals are introduced. 3 Meanwhile, the adsorption/ enrichment techniques can also be used in the analysis and detection of environmental hazards. Therefore, the research and development of various adsorbents are attracting increasing attention from researchers and engineers, which have become one of the hot issues in related elds.…”
