Dyeing cellulose textiles - with reactive dyes at high temps in neutral or acid aq media

摘要

Cellulose textiles, shape of which prevents dyeing in level shades, are satisfactorily dyed by (i) contacting with a water-soluble reactive dye, pref. with a monochloro-s-tirazine gp. contg. an amino, etherified OH, or an opt. substd. anilino gp., at temp. 100 degrees C in a neutral or weakly acid aq. medium contg. an electrolyte, until desired penetration and exhaustion are achieved; (ii) fixing dye on material by treatment with an acid binder.
