摘要
采用乙醇胺对胶原水解物酰胺化 ,采用二乙醇胺与甲醛的缩合物胺化 ,制得了阳离子蛋白填充剂。用该填充剂对铬鞣革进行填充 ,可使革厚度、丰满度、粒面紧实度明显增加 ,革对染料的吸收率显著提高。
A cationic protein filling agent has been prepared from collagen hydrolysate by amidation with ethanolamine and amination with diethanolamine-formaldehyde condensate. It has been found that the thickness and fullness as well as the grain tightness of chrome leather can be increased by applying the flling agent to the leather, and the absorbility of dyestuffs can also be increased by the agent.
