1 sty 2021 · The textile dyeing process primarily involves the transfer of chemical substance or precursor from their aqueous solution to the fibre surface via adsorption; and later on, dye slowly diffuses into the fibre.
1 sty 2014 · During the dyeing processes, the concentrations of dye in the liquor and on the fibre surface at a particular point at any time may not be at equilibrium with each other; a dynamic model is therefore required which represents the time dependency of the concentrations of the dye on the fibre surface.
1 sty 1994 · A knowledge of the physical chemistry of dyeing is useful for explaining and predicting the attraction and substantivity of dyes to fibers under practical dyeing conditions. The processes of adsorption, diffusion and related phenomena markedly influence such dyeing.
8 sie 2023 · The dyeing and finishing step represents a clear hotspot in the textile supply chain as the wet processing stages require significant amounts of water, energy, and chemicals. In order to tackle environmental issues, natural dyes are gaining attention from researchers as more sustainable alternatives to synthetic ones.
2 lip 2024 · Introduction. In recent years, with increasing concern about environmental issues, the use of natural dyes for textile dyeing has been increased. Natural dyes are biodegradable and prevent...
5 dni temu · The dyeing solutions were prepared by mixing the dye with Milli-Q water, while the textile samples were cut into 2 × 2 cm squares. All of the samples were immersed in 1:10 (textile weight:solution weight) dye bath; for all of the samples, 100% by weight of the dye was used in order to operate under optimal conditions.
1 sty 2011 · The dyeing procedure can be carried out in exhaust dyeing (batch), continuous or semi-continuous processes, in general, involving a sequential mechanism, that includes migration,...
