Sarawhite-CLE is a high light fastness (grade 5) optical brightening agent for Polyamides. Sarawhite-CLE imparts brilliant whites with violetish white shade on the treated fabrics. It has good affinity for nylon under high temperature. Sarawhite-CLE can be applied by both, exhaust as well as by continuous method. It shows good fasatness to light and chlorinated pool water. Sarawhite-CLE being stable to most of the bleaching agents, combined bleaching and optical brightening process can be carried out.
