this series are wool reactive dyestuffs with high performance. it contains double reactive groups, with its water fastness , high stability, good performance in wet fastness and free of heavy metals, can meet oeko-tex100 environmental demands.
main features
contains α-bromo-acrylamide active group, full, especially suitable for wool worsted industry.
* especially suitable for the dyeing of machine washable wool.
* suitable for the dyeing of high temperature or boiling temperature.
* good light fastness
* stay with a high performance of high-wet because of solved by the chlorinated water or shrinkproof.
* can be combined with the cationic dyes to dye the wool/acrylic blended fibers.

dyeing prescription
a: penetrant ca 0.5-1 g/l
dye leveller b 1-2 g/l
acetic acid x g/l
adjust ph=4.5-7
b：dyes x%
washing crafts
put the sodium carbonate or ammonium hydroxide to the dye bath, adjust the ph to 8-8.5, and keep 15-20mintues under the temperature of 80-85℃. then fully washed it by cold water and adjust the dye bath to ph=5 by the acetic acid.
