Leveling Agent (Polyester): Solvent‑free, High Yield, Brighter Colors

Leveling Agent (Polyester) is a yellow transparent liquid (≥30% actives, pH 6–7) for hightemperature jet dyeing of polyester. Solventfree, odorless, nonflammable. It provides excellent retardation and migration, giving higher color yield and brighter shades from macromolecular dyes. Use 0.4–0.5 g/L at 130°C with disperse dyes (1.5–3:100 ratio).

Product selling point introduction

What Problems Does It Solve? Where to Use?

Leveling Agent (Polyester) solves uneven dyeing, poor color yield, and dull shades in polyester high-temperature jet dyeing. It is used with disperse dyes (macromolecular dyes) at 130°C. The product provides excellent retarding and migrating properties, ensuring level dyeing without streaks or spots. It is ideal for polyester fabrics in overflow dyeing machines.

What Makes It Attractive & Different?

Unlike traditional leveling agents that may contain solvents, have strong odors, or be flammable, our Leveling Agent (Polyester) is solvent-free, odorless, and non-flammable – reducing storage and handling risks. It delivers higher color yield and brighter shades from macromolecular dyes. Both dye uptake and brilliance surpass conventional products. The simple dosage (0.4–0.5 g/L, ratio of agent to disperse dye = 1.5–3:100) makes it easy to use.

Why Buy Ours Instead of Others?

Competitors’ agents often sacrifice color yield for levelness or require solvent-based formulations that are hazardous. Our Leveling Agent (Polyester) combines superior leveling (retarding + migrating) with enhanced color strength and vividness – no trade-off. It is stable at 130°C, compatible with standard polyester dyeing processes, and backed by a 12-month shelf life. Choose a safer, high-performance solution that makes your polyester fabrics more brilliant and uniform at lower risk.
