Production description
     
       Polyamide fibers generally have a tendency to yellow during storage, mainly because phenol-containing substances (such as BHT) are transferred from packaging materials to fibers and combined with air-contaminated NOX gas to produce yellowing substances. The anti-phenol yellowing agent SD-4133 can prevent the oxidation of nitrogen oxides and phenolic substances, inhibiting the yellowing of storage and the yellowing caused by smoke in the air.
Characteristic and advantages

1. Prevents yellowing of white or light-colored nylon fabrics due to BHT during storage and transportation.
2. Does not affect the shade, easy to use, can be used in the same bath with the brightener.
3. significant effect on preventing storage yellowing of cotton fabrics caused by the application of cationic softeners and silicone softeners.

using method
        SD-4133recommended to use an impregnation process, which is also suitable for padding. It can be used in the same bath as the brightener, but should be tested for compatibility before use.

             pH value      4.0-5.0  (Citric acid regulation)
            50~60ºC ×20-30mins
         
        2.Padding :  SD-4133      10~40g/L    use citric acid regulate PH value to 3.5-4.5
Packaging and storage

     120Kgplastic drum (lined with plastic bag).Sealed storage, if stored under the specified storage conditions,           can be stored for about one year.
