Optical Brightener

  • Optical Brightener MST

    Optical Brightener MST

    Low-temperature stability: long-term storage at -7°C will not cause frozen bodies, if frozen bodies appear below -9°C, the effectiveness will not decrease after a little warming and thawing.

  • Optical Brightener NFW/-L

    Optical Brightener NFW/-L

    For reducing agents, hard water has good stability and is resistant to sodium hypochlorite bleaching;  This product has average washing fastness and low affinity, which is suitable for pad dyeing process.

  • Optical Brightener EBF-L

    Optical Brightener EBF-L

    The fluorescent whitening agent EBF-L must be fully stirred before use to ensure the whiteness and color consistency of the processed fabric.  Before whitening the fabrics bleached by oxygen bleaching, the residual alkali on the fabrics must be fully washed to ensure that the whitening agent is fully colored and the color is bright.

  • Fluorescent Brightener DT

    Fluorescent Brightener DT

    Mainly used for whitening polyester, polyester-cotton blended spinning, and whitening nylon, acetate fiber and cotton wool blended spinning. It can also be used for desizing and oxidative bleaching. It has good washing and light fastness, especially good sublimation fastness. It can also be used for whitening plastics, coatings, paper making, soap making, etc.

  • Optical Brightener CXT

    Optical Brightener CXT

    Fluorescent brightener CXT is currently considered to be a better brightener for printing, dyeing and detergents. Due to the introduction of morpholine gene into the whitening agent molecule, many of its properties have been improved. For example, the acid resistance is increased, and the perborate resistance is also very good. It is suitable for the whitening of cellulose fibers, polyamide fibers and fabrics.

  • Optical Brightener 4BK

    Optical Brightener 4BK

    The cellulose fiber whitened by this product is bright in color and non-yellowing, which improves the shortcomings of the yellowing of ordinary brighteners and greatly increases the light resistance and heat resistance of the cellulose fiber.

  • Optical Brightener VBL

    Optical Brightener VBL

    It is not suitable to be used in the same bath with cationic surfactants or dyes. The fluorescent whitening agent VBL is stable to the insurance powder. Fluorescent brightener VBL is not resistant to metal ions such as copper and iron.

  • Optical Brightener ST-1

    Optical Brightener ST-1

    This product is used at room temperature to within 280℃, can degrade 80 times of soft water, acid and alkali resistance is pH = 6~11, it can be used in the same bath with anionic surfactants or dyes, non-ionic surfactants, and hydrogen peroxide. In the case of the same dosage, the whiteness is 3-5 times higher than that of VBL and DMS, and the alignment energy is almost the same as that of VBL and DMS.

  • Optical Brightener ST-3

    Optical Brightener ST-3
