SmartDye uses equations of physical chemistry to calculate the adsorption, diffusion and reaction of dyes
during an exhaust dyeing process. There is one version for the dyeing of cellulosic fibres with reactive dyes and one version for the dyeing of polyester with disperse dyes.
The software allows the user to specify the physico-chemical properties of the dyestuffs (affinity, diffusion coefficient etc.) as well as the application conditions (dye amounts, temperature profile, liquor ratio etc.).
SmartDye has been designed as a tool for textile professionals and students to better understand the complex, often competing influences which dyestuff properties and processing conditions have on dye yield and dye distribution inside the fibre.
