Ink-jet printing of nylon fabric using reactive dyestuff

摘要

This study discusses ink-jet printing of nylon fabric with reactive dyestuff. Specifically, this paper investigates the impact of the concentration levels of pretreatment paste on fabric permeability, and examines the influence of various acid agents, hygroscopic agents and different processing conditions on colour yield. Results show that ink-jet printing displayed excellent wet fastness in repeated wash testing. This study used four reactive dyestuffs, cyan, magenta, yellow and black, all of which achieved both wash fastness and crock fastness of grade 4.
