RESEARCHES ON DYEING OF COTTON FABRICS WITH ACID DYESTUFFS, CONCOMITANTLY WITH CREASE-RESIST TREATMENTS

The paper analyzes the results obtained on dyeing of cotton cellulosic fabrics with acid dyestuffs, on employing crease-resist agents with p olyfunctional structure. The conclusion was reached that no chemical o r physical bonds occur between dyestuffs and the fiber, the dyestuffs being fixed onto the resin's aminic groups formed as a result of the t hermal, crease-resist treatment. Washing resistance of the cellulosic materials thus dyed attains the values obtained as a result of dyeing with direct dyestuffs, specific for these types of fibers.
