Chemistry and physical reason.
Appearance: white liquid.
Chemical composition: sulfonic acid base surface active organic matter.
Ionicity: 3-4
Solubility: soluble in water (stirring)
Features and advantages
Especially the yellowing of nylon, spandex and its blended fabric during packaging and storage due to exposure to chemical components such as vanillin and dibutylation.
use
It is suitable to prevent yellowing and other phenol yellowing in white and light products.
application
1. It can effectively improve the phenol yellow fastness of nylon fiber and its blended fabric affected by BHT.
2. It can prevent the yellowing of all nylon fiber, nylon blended fabric and elastic fabric.
Usage and dosage
Dipping process: c2-5%.
PH: 4.0 to 4.5
Temperature: 80 ℃
15 minutes to heat up to 80 ℃, insulation 20-30 minutes
Pressure suction method: it is not recommended to be used for thicker cloth, because the operation is low and the dosage is large. If necessary, it can be pressed twice to achieve the anti-yellow index.
