Dye

This product is suitable for the dyeing and papermaking of various waste pulp and wood pulp, including colored cardboard, decorative base paper, office paper, food packaging paper and specialty paper. It effectively corrects mottled hues and dull background tones of pulp, and improves the color uniformity of paper products. It features good compatibility, no wire clogging and no cylinder adhesion. Its special molecular structure forms firm combination with paper fibers, ensuring uniform and long-lasting color, as well as excellent resistance to fading and color migration. It is widely applied in the production of various colored paper products.

It is recommended to dilute the dyes to the required concentration with warm water, then add to the mixing chest or before the fan pump. Sufficient mixing in pulp is required to ensure uniform coloring. Avoid mixing different color dyes to prevent precipitation. The dosage depends on target color depth and pulp type, generally ranging from 0.01% to 0.5% based on oven-dry pulp. Preliminary lab testing is recommended to confirm the optimal dosage.
