染色酸RS在高温染色中的适用性

Applicability of dyeing acid RS in high temperature process

染色酸RS为复合型有机酸,在高温条件下不会造成纤维素纤维水解降强,有很好的安全性和高温染色适用性。在高温染色中用作pH值调节剂,其使用效果与冰醋酸基本相同,而染色效果(艳度、深度)好于冰醋酸。将染色酸RS与醋酸钠复合使用,可大幅提高其pH值缓冲能力,确保染浴pH值稳定。

Dyeing acid RS is a composite organic acid, it will not cause cellulose hydrolysis at high temperature, and has good safety and applicability at high temperature. Act as a pH value regulator, it features the similar utilizing effect and better dyeing results compared to glacial acetic acid. Combined with sodium acetate, buffering capability of dyeing acid RS is greatly improved.
