PERMABRIL® Bi-Functional Reactive Dye
PERMABRIL® Bi-Functional Reactive Dye:
These products offer superior fastness properties on cellulose and cellulosic blends — especially fastness to perspiration, light, chlorine and peroxide.
PERMABRIL® Bi-Functional Reactive Dyes are suited for exhaust and continuous application methods. They are used extensively for cold pad batch dyeing due to their superior alkaline stability and ability to react with cellulosic fibers at low temperatures.
These dyes exhibit little dependence on dyeing temperature and liquor ratio and have good wash-off properties.
