Megazol

 

Megazol® Dyes, which contain an alpha-bromoacrylamido reactive group, are reactive dyes for the coloration of wool. The mechanism of the fixation of Megasol 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.

鈼 Properties

High light fastness
Excellent wet fastness
Non-metailzed dyes, meet stringgent environmental regulations

鈼 Applications

Yarns, machine-washable wool
Shrunk-treated woven and knitted goods*
Loose wool stocks and yarn for carpet 锛 rugs
