El defecto principal de rendimiento del teñido de nylon con colorante ácido que es su dependencia del valor de pH del baño de teñido, es decir, su velocidad y cantidad de teñido cambiarán significativamente con la fluctuación del valor de pH del baño de teñido. De acuerdo con las inspecciones, cuando se usan comúnmente colorantes ácidos para teñir nylon, el rango de pH óptimo del baño de tinte es 4.5-5.5. Porque en este rango, el rendimiento del colorante que es el más alto y la estabilidad del color es la mejor. Cuando el pH del baño de teñido es superior a 6, la velocidad de teñido se vuelve significativamente más lenta y la profundidad del color se vuelve significativamente más superficial. Cuando el pH del baño de teñido es inferior a 3, la velocidad de teñido aumentará repentinamente y la profundidad del color aumentará rápidamente. Read More
