Cotton brightener SD-4074 is a stilbene derivative with high whiteness and a wide range of applications. It is a fluorescent brightener suitable for whitening cotton and its blended fabrics.
[Features and advantages]
1. Suitable for whitening, whitening and whitening.
2. High whiteness, strong fluorescence, low dosage, not easy to stain and easy to chemical.
3. It is used for bleaching and extra-white processing of cellulose fibers, regenerated cellulose fibers, and nylon fibers.
4. Higher whiteness than ordinary whitening agents can be obtained at the same dosage
5. Wide range of pH value.
6. Wide dyeing temperature range, stable performance in hydrogen peroxide.
7. Has good resistance to high temperature yellowing.
[Application range]
SD-4074 is best mixed with cold water and then dissolved in 80 ° C hot water to obtain a homogeneous solution, which is then added to the application bath or make-up solution.
