            Megazol

            Megazol Dyes, which contain an alpha-bromoacrylamido reactive group, are reactive dyes for the coloration of wool. The mechanism of the fixation of Megazol dyes is based on the ability of this unique multifunctional group can form a covalent bond with various amino acid side chain sites within the wool protein, as such, it renders an excellent wet fastness and superior dyeing property. Recommend for wool, mercerized wool, cashmere and its blends.

            Properties
            High light fastness • Brilliant color
            Excellent wet fastness •Superior dyeing reproducibility ,
            High fixation rate with low dye hydrolysis
            Non-metalized dyes, meet stringent environmental regulations
