Product features


  • Does not contain prohibited substances such as benzene, azo chlorine ammonia; has certain bactericidal and bacteriostatic effects.

  • Suitable for dyeing with different compatible dyes; the dosage depends on the dyeing depth, the selected cationic dye K value, f value, and the saturation value of the polyester fiber.

  • Replace the conventional leveling agent M08 and buffering agent RCT. This product has strong affinity for polyester fibers, excellent buffering and leveling properties, and uniform coloration of polyester fibers.
