Anti-Yellowing Agents

... protect textiles from thermal and storage yellowing.
Thermal anti-yellowing agents not only reduce the tendency for PA or PA/EL goods to yellow during the heat-setting and moulding processes, they also lower the chance of CO/EL goods yellowing during heat-setting. Storage anti-yellowing agents reduce phenolic yellowing of PA and PA/L goods as well as PES/EL products and other blends. Depending on the application, there are special products that give goods a neutral pH value or help prevent unwanted brownish yellow spots caused by certain finishing processes.
