Product Features
1. The anti-yellowing dyeing auxiliary Seeyon®N-2462 is an N,N-dimethylacetamide (DMAC) solution of a polymer of alkyliminobiethanol and dicyclohexylmethane diisocyanate.
2. The anti-yellowing dyeing auxiliary Seeyon®N-2462 is applied to the polyurethane elastic fiber (spandex) industry to improve the dyeing performance of spandex. This product has a polyurethane structure, good material compatibility with spandex, high-temperature volatilization resistance, good migration resistance, good dyeing synergy, and yellowing resistance. It has better inhibition and prevention effects on the discoloration of spandex (such as discoloration caused by light and smoke fumigation). It is a spandex auxiliary with the functions of anti-yellowing and dyeing aid.
