Optical Brightener CLE for Nylon and CottonApplication Method:
The whitening agent can be evenly mixed directly with nylon polymers, either by adding it during the molten state or by mixing it with nylon pellets or powder during the early stages of production.
It can be added during extrusion molding or injection molding, ensuring uniform distribution throughout the polymer matrix.
Temperature should be controlled during use to prevent decomposition or degradation of the whitening agent.
Optical Brightener CLE for Nylon and Cotton Achievable Effects:
Whitening Effect: CLE significantly enhances the whiteness and brightness of nylon, giving it a more brilliant and white appearance.
Yellowing Masking: The whitening agent can neutralize yellowing in nylon, particularly in products that have undergone multiple processing cycles.
Enhanced Appearance: In addition to increasing whiteness, the whitening agent improves the overall appearance of nylon products, making them more suitable for high-demand applications such as textiles and industrial components.
