Process for printing and dyeing of textiles

摘要

A process for printing and dyeing sheetlike fibre materials with anionic dyes comprises a) first applying to the sheetlike fibre material an aqueous solution containing a fixing alkali and a compound which contains a primary, secondary or tertiary amino group or a quaternary ammonium group, which may each also be part of a heterocycle, by using a printing process, then b) subjecting the sheetlike fibre material to a fixing treatment to modify the sheetlike fibre material, and finally and optionally c) dyeing the modified sheetlike fibre material one or more times with a customary exhaust or padding method.
