Molecular structure


Color comparison of cotton and nylon dyed in the same bath at different dyeing temperatures

When cotton and nylon are dyed in the same bath, reactive red 3BS will color nylon. As the dyeing temperature rises, the color on nylon becomes darker.

CAS: 93050-79-4 Reactive red 3BS fastness performance

1)CAS: 93050-79-4 Reactive red 3BS has good washing, rubbing and other fastnesses. The chlorine fastness is also good among reactive dyes. The light fastness is slightly worse, and the light color cannot meet the requirements. CAS: 93050-79-4 Reactive red 3BS dye below 0.1%, the light fastness is difficult to reach 3-4 grades, so for products with high light fastness, consider using reactive dyes with high light fastness To replace.

2)CAS: 93050-79-4 Reactive red 3BS In the dyeing or printing reaction process, because most of the reaction is the vinyl sulfone active group, the color fastness to alkali and perspiration of the final product is lower than the color fastness to acid and perspiration. The pH value of the finished fabric surface of the printing and dyeing factory is generally controlled in weak acidity. The covalent bond formed by vinyl sulfone and cotton fiber is stable under weak acid conditions. Therefore, After a long period of storage, the color fastness of the fabric will not decrease significantly
