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.

1. Fluorescent whitening is carried out in the pulp.
2. Fluorescent whitening is carried out in surface sizing.
3. Fluorescent whitening is carried out during the coating process.
1. It can be directly added into the slurry, the conventional dosage: 0.05-1.2% (absolutely dry slurry).
2. It can be used together with commonly used starch, CMC and PVA in surface sizing to obtain a better whitening effect. The conventional dosage is 0.5-10g/L.
3. During the coating process, it can be added at any position. It will achieve better results when used with PVA, CMC, and starch. Conventional dosage: 0.1-1.4% (to the weight of the coating)
