EFI Mezzera Mercerizing

Extremely delicate treatment for first-class fibres

Mercerizing is one fundamental step in cotton fabric preparation. During the mercerizing process, the crystalline structure of the cellulose is permanently altered to the benefit of the macroscopic characteristics and fibre reactivity to the dyestuffs.
