  2,after the dissolution of the powder,the time for a long time,it will produce a trace of precipitation,so when the use of 300-400 mesh filter to filter out,to prevent the precipitation of substances into the next process.

  3,solvent metering are added to the dissolution vessel during dissolution,and then adding dye batches,stirring constantly increase after completion of a few minutes,wait for 1-2 hours,in the stirring,the static precipitation.If do not soluble dyes,adding proper amount of solvent,extraction of available dyes discard the remaining unwanted impurities.

  4,We have to hoose a good solvent and good dissolution method as the there will be precipitation if it is unqualified.color sediment will be many,dye content will more and more,will eventually lead to uneven dyeing,the dyeing effect is poor.
