BIOLEVEL DSL is a premium-grade Leveling Agent specifically developed for the high-temperature dyeing of polyester fibers and its blends. It operates as a highly effective dispersing and migrating agent, facilitating the uniform distribution of disperse dyes. By regulating the dye uptake during the critical heating phase, it prevents the formation of dye spots and ensures excellent color leveling, even on tightly woven or high-twist polyester yarns.
Key Benefits:
Superior Migration: Promotes excellent dye migration at high temperatures, effectively correcting any initial unevenness during the exhaustion phase.
Excellent Dispersion: Keeps disperse dyes in a stable, finely divided state throughout the dyeing cycle, preventing agglomeration and specking.
Controlled Exhaustion: Slows down the dye strike rate during the temperature-rise period (between 90°C and 130°C), ensuring deep and uniform penetration.
No Effect on Fastness: Does not adversely affect the final light, wash, or sublimation fastness of the dyed polyester material.
Application Guidelines:
Usage: Specifically designed for polyester dyeing in Jet, Package, and Beam dyeing machines under high-temperature (HT) conditions.
Dosing: Apply at 0.5 to 1.0 g/l, depending on the depth of the shade, the heating rate of the machine, and the density of the fabric.
Compatibility: Highly effective when used in acidic dye baths (pH 4.5 – 5.5) typical for polyester processing.
