THE NITROGEN SEALED REACTOR TECHNOLOGY (Pat.)

MULTI DEEP AND FEWER DYE BOXES IS POSSIBLE, SAVINGUP TO 20% INDIGO DYESTUFF

The revolutionary concept of Mezzera relies on making the deepingoutside the bath in a controlled, non-oxidizing environment, thusmaking the deeping time longer. The deeper penetration allows tosignificantly save indigo dyestuff and chemicals.

TECHNOLOGY A LA CARTE

Nowadays, after many years of successful work and results, Mezzeraoffers indigo dyeing technology with sealed Nitrogen Reactor for allthe dyeing styles.

LOOPDYE - ALLROUNDER The slasher that dyes like a rope

• Highest fastness• No center-side differences also with dark blue• Lowest liquor quantity, only 1000 litres on indigo bath• With pre-reduced indigo, easy to dye the dark blu.• Cheapest machine in the category• Simplest machine can be operated with minimally skilled

personnel• Fast return on investment• High consistency, total isolation of dyeing chamber from outside• Lowest running costs. • Wide variety of products for the international market.

SLASHER DYE - MAXIMUM FLEXIBILITY

• Multi-box dyeing range for the widest and richest program ofproducts and specialities

• Highest production speed thanks to the Sealed Nitrogen Reactor• Wide variety of options available to complete the specialties

NITROGEN ROPE DYE - A CLASSIC RE-INVENTED

• State-of-the-art-technology based on Sealed Nitrogen Reactor(Pat.)

• Fully automatic dosing and monitoring of the range based on PLCcontrol

• Reduced amount of dyeing liquor • AC drives and perfect tension control during dyeing• Highest productivity in its class • Super dark shades at higher production speeds

LEUCO DEEPING The reduced indigo (LEUCO)penetrates into the crystallineinterstitial substrate of the cellulose

AIR OXIDATION After the squeezing to remove thereducing agent, the oxidized indigomolecule changes shape and isblocked into the cellulose
