Polymer additive - anti - yellowing agent
Textiles are indispensable in our life. However, yellowing of textiles in the process of storage, transportation and wearing will directly lead to economic losses, so yellowing resistance is always a problem faced by the textile and apparel industry
There are two kinds of photoyellowing and phenolic yellowing in textiles.
Light yellowing refers to the color yellowing of textile surface caused by sunlight or ultraviolet light. Phenolic yellowing refers to the yellowing of the fabric by the action of nitrogen oxide or phenolic compounds.
In surveys, white fabrics sometimes yellowed in storage. In the yellowing part after acid treatment, the yellow disappeared and returned to the original white, if the drop of lye again yellow. The results showed that it was mainly caused by phenolic yellowing.
The main causes of phenolic yellow: The antioxidant BHT (2, 6-di-tert-butyl-p-cresol) commonly used in packaging materials reacts with nitrogen oxides (NOx) in the air to produce DTNP (2, 6-di-tert-butyl-p-nitrophenol). DTNP is colorless in acidic state, and easily sublimated and transferred at room temperature. When alkaline substances are encountered, it immediately turns yellow
Therefore, the anti-yellowing agent 130 launched by our company for the textile industry can effectively prevent raw materials from yellowing. The product has good selectivity to nitric oxide (NO) and nitrogen dioxide (NO2), which can effectively prevent yellowing of raw materials and some polymer surfaces during processing.
