Phenolic yellowing is often occurred during transportation or storage of white or light color fabric that is exposed to nitrogen oxides (NOx) gas in the air and packing material such as poly (ethylene oxide film of antioxidants such as BHT) , it will greatly influence appearance of the fabric, esp. for nylon fabric. So this kind of fabric is often finished by anti-yellowing agent. KH-2 can effectively reduce the phenolic yellowing caused by the above reasons.

Advantages:
Has a good function of anti-phenolic yellowing for Nylon.
can prevent phenolic yellowing that is caused by nitrogen oxide (NOx) in the air, contained in packing material such as poly (ethylene oxide film of antioxidants such as BHT)
