RP-150 is an auxiliary agent developed for soap washing of fibre
reactive dyes, and it has low foam and excellent antifouling
properties of soaping of reactive dye printing. RP-150 has
excellent effect on floating colour removal which caused by dyeing
of reactive dyes, unbound dye, water decomposition dye. RP-150 also
has excellent ability to preventing white pollution effect, high
fastness to dyeing and printing after soaping and good
compatibility with fixing agent. In addition, RP-150 continuous
used in soap washing process will not produce problems.
Appearance: Colourless to light yellow transparent liquid
Composition: Special non-ionic surfactant
Ionic Property: Non-ionic
PH value: About 6.5 (100% pure)
Solubility: Soluble in cold water with any proportion
Characteristics and Applications
1. Usually reactive dye printing material has good white
antifouling effect. RP-150 has good white antifouling effect for
bright colour such as reactive turquoise blue, and RP-150 used for
soaping wash still can get a bright hue.
2. RP-150 has excellent removal effect for water decomposition dye
and dye which not dyed, and RP-150 can improve washing fastness of
the dye and printing.
3. RP-150 has good compatibility of colour agent. In the process of
continuous soap washing, it is easy to cause the negative effect of
the residue of the soap lotion, and RP-150 does not need to worry
about this problem.
4. RP-150 will not reduce the white background of the printing
material, and it will make the pattern bright.
5. RP-150 will not produce the white bottom sticky dirt and the
tissue of high drainage foam problem caused by the bubble in the
process of soaping.
6. RP-150 has excellent resistance to hard water, and will not have
the soap calcium problems. Even used soda ash, hard water in the
soaping process, it is still able to maintain a good soaping
The optimum usage of PR-150 varies with the type of dyed fabric,
morphology, dyed or printed shades, soaping processes and
equipment. Generally based on 1-3g/L and appropriate to increase or
