What makes a reactive dye

Covalent bond. Permanent color.

Reactive dyes form covalent bonds with cellulosic fibers — meaning the dye becomes part of the fiber molecule itself. The result: wash fastness that no other dye class can match, the vivid shade range demanded by today's fashion cycles, and the process efficiency that modern mills require.
