The reactive dye ENF series is based on the international advanced Supra- molecular chemistry theory，the application of this theory on the research and development and manufacture of dyes is a major innovation in the development of reactive dyes,it realized the birth of a new generation of fool-type reactive dyes.The series of dyes have similar molecular structures and excellent dye compatibility,synchronization of three original colors achieves the same stability as monochrome dyes.It has a high success rate from laboratory to mass production，and with stable dyeing process，regardless of any process parameter changes during dyeing, the color difference and cylinder difference are extremely small, which greatly reduces the repair rate and the overall cost of dyeing, improves production efficiency.
