Procedure for obtaining Dyes for ink-jet Printing tecnicaDe '' on Fibers modified with Anionic Textile dyes.

摘要

In this paper, the dyeing process of plane structure fiber materials, especially those containing anionic dyes or cellulose, especially those containing one or more fiber active groups, is described. In this process, an aqueous solution without anionic dyes is used. 1. Pretreated and modified bases with a compound containing a primary, secondary or tertiary amines group or quaternary ammonium group, preferably bases with low or no electronic content,Considering that these groups may even be part of the heterocyclic cycle, and according to this dye procedure, the application of dye solution is carried out by spray technology "spray jet". Generally speaking, later washing can be avoided. It avoids the economically expensive cleaning of the waste water, which is contaminated by the excess dye pool in the normal procedure. The use of fibrogen dyes can bypass dyes determined by the use of alkali, usually by short-term heat treatment.
