This product is a special yellowing inhibitor for polyamide fiber (nylon fiber) to prevent yellowing of nylon fabric during storage.
Performance Characteristics
The macromolecule has obvious spatial steric effect and can effectively prevent the binding of DTNP with the amino group of nylon.
Low foam, suitable for impregnation, dipping and rolling, can be used in the same bath with fluorescent whitening and dyeing.
The fabric exhibits excellent permeability, absorbs more material, has a more uniform surface, and is more durable.
The buffer system protects the color and light stability of the fabric.
Component
Sulfonated organic matter.

Compatibility
Compatible with nonionic and anionic auxiliaries. May form precipitates with cationic auxiliaries.
Usage method
It can be used alone or in the same bath as fluorescent brighteners and dyes. When used alone, no acid adjustment is required. When used in the same bath as other additives, generally only a pH value below 5 is needed. It is recommended to test in advance the impact on the performance of other additives. The process and usage amount can be used as references.
