| Use | reactive Alexandrine KN-G can be used for dyeing cotton and viscose fibers, suitable for various dyeing methods, with moderate affinity, the fixation rate is low, can be dyed in single color, also used for green, dark green and so on. Also used for cotton, viscose fiber fabric direct, anti-dyeing printing, can only be used for light color. For silk, wool, nylon, Vinylon dyeing, light fastness is poor. For the direct printing of cotton blended fabric, it can be printed in the middle and deep color, and has good fastness. used for dyeing and printing of cotton, viscose, wool, silk and other fibers |
| production method | copper phthalocyanine, P-(2-sulfated ethyl sulfone) aniline, chlorosulfonic acid and thionyl chloride are used as raw materials, the copper phthalocyanine is first subjected to a chlorosulfonation reaction with chlorosulfonic acid and thionyl chloride, and then the product is condensed with P-(2-sulfatyl) aniline, salting out, filtering and drying to obtain a finished product.. |
