Multiple Color PH Changing Dye

We have been a celebrated manufacturer of Multiple Color PH Changing Dye in the market. In the case of acid dyeing, a low pH helps to form the hydrogen bonds that attach acid dyes to protein fibers, such as silk and nylon as well as wool. Silk can be dyed at low pH (acidic) or high pH as with cellulose fibers; wool can only be dyed at low pH because it is damage by high pHs. Multiple Color PH Changing Dye is known for its effectiveness.
