ce-type reactive dyes
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.
ce series reactive dyes contains α-bromo-acrylamide , monochlorotriazine etc various reactive groups, which is high solubility , stable hydrolysis resistance and especially suitable for the middle and deep dying.
* high absorption rate and fixation rate
* excellent dyeing reproducibility
* it can maintains excellent fastness to wet processing even though dyeing deeply.

a: penetrant ca 0.5-1 g/l
dye leveller b 1-2 g/l
acetic acid x g/l
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.
