摘要：
Biodegradable quaternaries of amidoamines are disclosed for use as dye leveler compounds in the basic dyeing of acrylic and other fibers. The quaternary compounds of the invention have leveling activity equivalent to benzyl trimethyl ammonium chloride, but with much higher biodegradability, and generate low foam.
