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.
