Texnology®KH3 Anti-Heat Yellowing Agent prevents fabric yellowing during high-temperature heat setting. Texnology®KH3 Anti-Heat Yellowing Agent reduces heat-induced yellowing of nylon and its blends during pre-setting, post-setting, and molding. Texnology®KH3 Anti-Heat Yellowing Agent minimizes color change on light or sensitive shades during heat setting. It also gives whitening fabrics maximum whiteness. It works well on nylon and elastane blends. It prevents yellowing risks during heat setting. Heat setting gives synthetic fibers and their elastane blends dimensional stability or removes curling edges. It also reduces yellowing during molding at 190–200°C.
