摘要
分散染料染涤锦织物存在同色性和湿牢度差等问题。涤锦织物染中深色,必须采用分散/中性染料或分散/酸性染料一浴一步法染色。通过分析分散染料染锦同色性差、皂洗沾锦牢度差和色泽耐晒牢度差的原因所在,指出在染整加工中要选择低温型(E型)分散染料,设定的染色温度应低于120℃,严格控制升温速率,添加阴/非离子表面活性剂的复配物,并调节pH值至4～5,以获得优良的二相同色性。
Due to the poor union-color property and wet rubbing fastness, one bath one step dyeing of polyester/polyamide in medium and deep shade are carried out with disperse/neutral dyes or disperse/acid dyes. The reasons for poor union-color property, low staining scale of color fastness to soaping of polyamide component and poor light fastness are discussed. It is pointed out that polyester/polyamide dyeings can obtain good union-color property by dyeing with selected low energy （ E type） disperse dye at temperature below 120 ℃ and pH value of 4-5, controlling heating rate strictly and adding anionic/nonionic compound surfactants.
