Sinophor® Fluorescent Brightener

Sinophor® APC

Sinophor® APC is especially suitable for whitening and brightening knitted cotton fabrics. FBA220 introduces multiple water-soluble groups in its structure, which not only has good water solubility, but also has good perspiration fastness and acid resistance. Even when the PH is 3-4, it still has a good whitening effect on cellulose fibers.

Since the whitening agent is liquid, it is not as difficult to solvent as the powdery whitening agent, and there is no dust pollution. It only needs to weigh a certain amount according to the whiteness requirement and dilute it with water in any proportion.
