EJENDOMME:

Optical Brightener VBL is a typical representative of bis(triazinylamino)stilbene derivative.It can be soluble in 80 times soft water and shows anion character and the pH value resistant to acid and alkali is 6-11 and the expected pH value of dyeing bath is 8-9. When used in acidic solution, the fluorescence will weaken owing to the increase of acid and turns into yellow color. It can resist 300ppm hard water, 0.25% free chlorine, but don't resist the ion of copper and iron. It show stability to rongalite, but cannot be baked at high temperature. It has bluish voilet optical color and can be used in the one.bath medanionic surfactant or dyestuff and nonionic surfactant and oxydol, unsuitable for application in cationic dyestuff and surfactant and raw synthetic resin.

ANVENDELSE:

1. Optical Brightener agent for cotton fabric and gluing products, light color or printing products. It show normal sun light resistance and has good affinity medcellulose fiber, normal level dyeing result. can be used in printing pulps and exhausting or padding dyeing.

2. Optisk Brightener-middel til polyvinylalkoholfiber og polyamidfiber.

3. Optisk Brightener-middel til polyvinylalkoholfiber og polyamidfibermiddel til papirfremstillingsindustri, papirmasse eller maling.
