Disperse dyeing of synthetic fibres in supercritical medium

摘要

Various materials made from synthetic fibres (yarns, filaments, fabrics, non-wovens) are dyed with a supercritical fluid system using water insoluble dye (disperse dyes). The dyeing process includes the deposits from previous textile processes (sizes, spin finishes) in order to obtain better fastness to rubbing and higher dye uptake.
