First class anionic polyamide fixing agent

Excellent and brilliant shades on polyamide turn out particularly well with the new aftertreatment agent PAFIX No1.
This product rounds off the existing CHT-REWIN aftertreatment range of anionic fixing agents and sets new benchmarks.

PAFIX No1 is an innovative premium aftertreatment agent and stands out for its unique properties and high environmental compatibility. The all-round fixing agent is highly suited for standard shades as well as for brilliant PA dyeings with fluorescent dyes such as BEMACID Luminous Red E-B (rhodamine type) and BEMACID Luminous Yellow E-B (flavine type).

PAFIX No1 guarantees an outstanding and lasting balance between good fastness level and high fluorescence.
PAFIX No1 is particularly suited for sportswear and functional wear that is often washed.
