New Mathematical Model for Determining Time-Dependent Adsorption and Diffusion of Dyes into Fibers Through Dye Sorption Curves in Combination Shades

Abstract

Time-dependent dye uptake of textile substrates can be described by a new mathematical model that divides the dyeing process into two parts, dye adsorption and dye diffusion. Using this model, the influence of temperature (20-80°C) and NaCl concentration (2.5-10.0 g/L) on the dye uptake of a trichrome dye combination of C.

The role of nanoclay partitioning and fibril formation on dyeability of blend nanocomposite fibres

“…The dyeing process of nanocomposite fibres with disperse dye is divided into the three consistent processes: diffusion of dye in the solution, sorption at fibre surface, and diffusion into the fibre. In the case of a finite dye bath, the dye concentration at the fibre surface continuously decreases during the sorption process until equilibrium is achieved between the dye concentration in the fibres and bath .…”

Dyeing with Hydrotalcite Hybrid Nanoclays and Disperse, Basic and Direct Dyes

“…For this purpose, the so-called colour fastness tests are carried out. It should be remembered that hybrids have been used whose dyes have an affinity for the specific fibre that has been introduced into the dyeing process; the direct dye shows an affinity for cellulosic materials such as cotton [56][57][58], the dyes (cationic) have an affinity for the chemical structure of PAN (anionic) [59] and in the case of polyester, they are dyed by the disperse dyes as if they were an alloy [60][61][62] since when they reach the glass transition temperature (~68 • C), the dye and textile join in a similar way to that of metals when they are melted. Above the glass transition of polyester, both phases are mixed at the molecular scale.…”
