Tanning industry is the sector that in recent years has achieved the most surprising steps ahead in matter of environmental sustainability, especially in Italy. A result which builds on continuous research and cutting-edge technical solutions, which involves the entire supply chain and of course sees the chemical companies engaged in the foreground. This environmental awareness, which has always characterized Syn-Bios SpA, was one of the reasons that led to the conception and creation of INK FOR LEATHER range.
The traditional dyestuffs contain salts, sulfates and chlorides in variable percentages, which contribute to the pollution of tannery sewage. INK FOR LEATHER colors are totally free of these substances.
Thanks to their chemical nature, INK FOR LEATHER colors are insoluble in water therefore, during fixation, they are adsorbed on leather allowing to obtain totally exhausted bath, avoiding color contamination of sewage.
COD analysis (chemical oxygen demand) of a dye bath made with INK FOR LEATHER colors shows a significant reduction of the value compared with dyestuffs dyeing bath one.
