    Example2. Curtains made of polyester tulle braid are usually pre-washed in a non-intermittently operating washing machine, dried in a drying-: shirn, in a 120 ° C machine and rolled over into a dyeing pile. After introduction into the NT-dyeing apparatus, the material is treated with a solution containing, under the circumstances, the 0.05% optical brightener of the compound of formula III (example 1) or formula V, or mixtures thereof.
