A production-grade cationic dye engineered for fast fixation and low migration, delivering reliable deep-black shades across lab and mill scales. Offered as powder and pre-dispersed liquid.
Cationic Black FDL (FDL = Fast-Dry / Low-migration) is formulated to meet modern production needs where reduced cycle time and minimized interlayer bleed are critical. Unlike standard trade descriptions, FDL focuses on predictable behavior under continuous processes and robust tolerance to common auxiliary packages.
Mainly used for medium shade and deep shade acrylic knitted underwear,acrylic loose fiber, acrylic carpet printing, and light shade, medium shade and dark shade bulked yarn dyeing.

"FDL" is our grade identifier emphasizing Fast fixation and Low migration characteristics — it's a formulation target rather than a regulatory standard. Always verify with lab trials for your substrate.
In some aqueous ink systems, cationic dyes like FDL can be used. Compatibility with binders and migration risk should be validated in ink formulations and print tests.
