Cautions of Fluorescent Yellow Fabric

 1. The whiteness of the semi-bleached cloth is directly related to the fluorescence of the finished cloth, requiring whiteness value ≥ 80%

 2. Active fluorescent yellow FL should be used 35 ~ 40 ℃ hydration material, otherwise, the dye is easy to appear cohesion

 3. The adjustment of finished color light can choose active emerald blue KN-G or young yellow 4GL

 4. The alkali resistance of reactive fluorescent yellow is poor, no caustic soda is added to the solid color solution, more soda can be used

 5. The sun fastness of ordinary reactive dye yellow is particularly good, but the sun fastness of reactive fluorescent yellow is grade 3
