Synozol K-Series provide dyes of new generation produced by developing new chemical structures or modifying existing chemical structures in order to provide properties of dyes distinctive from those of traditional reactive dyes. Dyes from Synozol K-Series are less sensitive to various dyeing conditions. In fact, the same dyeing conditions that apply to dyeing with Synozol HF and/or SHF Series dyes may also be applied to dyeing with dyes from Synozol K Series. These reactive dyes provide colors that are brighter than those provided by other reactive dyes. The recommended three primary colors also have a wide range of applications.
