printing process for regenerated cellulose materials with reactive dyes, and across the street,.

摘要

A process for printing on delustred regenerated cellulose material with a reactive dye to obtain deep level prints is characterized by padding before printing with a compound of the formula FORM:0925326/IV(a)/1 wherein X is =S, =NH or, preferably, =O, and R is a primary, secondary or tertiary amino or an ether group, an aliphatic radical of 1-6 carbon atoms or an acid amide radical. The compounds specified are urea, thiourea, guanidine carbonate, acetamide and methyl urea. They may be used in a 10% aqueous solution. Examples are given in which a variety of reactive dyestuffs are used.
