High‑temperature, high‑pressure dyeing is a key step for polyester and its blends. But this process often causes unevenness, specks, and shade differences. These defects hurt production efficiency and fabric quality. Achieving level dyeing at high temperatures while meeting environmental requirements is a major challenge for many mills. Guangzhou Lianzhuang Chemical developed TEXNOLOGY®RH12 high‑temperature leveling agent to solve this problem.
TEXNOLOGY® uses a special surfactant system. It has both retarding and migrating functions. It controls the initial dye strike effectively. Its moderate retarding action gives excellent leveling. Its unique molecular structure has affinity for both polyester fibers and disperse dyes. Even at high temperatures, it keeps stable dispersing and protective colloid effects. This keeps disperse dyes suspended and evenly distributed in the dye bath. It prevents dye molecules from colliding and aggregating under high‑heat conditions, which would cause specks and stains. This ensures smooth dyeing production.
In practice, TEXNOLOGY®RH12 offers multiple benefits. It dissolves easily in hot water. Its low‑foaming property suits jet dyeing machines. It avoids foam‑related defects. It solubilizes and disperses disperse dyes well, supporting level dyeing. It also chelates metal ions in the bath, preventing their negative effects. At the same time, its excellent dispersing power stops dyes from aggregating under high temperature and pressure, which prevents specks and stains.
TEXNOLOGY®RH12 high temperature leveling agent
With stricter environmental rules, TEXNOLOGY®RH12 meets compliance standards. It contains no banned chemicals. It supports green production. It dissolves easily in water and resists acids, alkalis, and hard water. It does not interfere with anionic dispersants, wetting agents, or other bath additives. This makes process upgrades easy for mills. The application is simple. Just use it with dyes in a high‑temperature bath to achieve the desired level dyeing.
