Softening consists of short-term processing of the dehaired leather by enzymes, under which influence the gneist and the epidermis remains are removed from the pores of the dehaired leather.
Enzymatic auxiliary multi-purpose agents "PROTEAZIM" are intended for ballast proteins, gneist and epidermis remains removal from the dehaired leather pores and the dehaired leather preparation for tanning in order to obtain smooth, clean leather semi-finished product with strong grain side and uniform color.- Ferment ООО
Auxiliary enzyme agent for tanning industry
Product description
Enzymatic complex of serine proteases with mineral filler (stabilizer).
Purpose
The use in soaking and ashing processes of leather production at the stage of softening of de-haired skins for removal of residual proteins, interfibre substances and gneist.
"Proteazim-Expert" makes it possible to prepare dehaired skins for further technological processes, in particular for tanning with ultimate production of smooth and clean semi-finished product with strong face and uniform coloring.
Recommended for all types of raw leather materials, including heavy steer hides.
Characteristics and use
"Proteazim-Expert" is a multi-purpose softening agent for all types of raw materials and leather.
Working temperature range for the agent is 20–55 ℃ (optimal: 45–55 ℃)
Working рН range 7–12 (optimal 8.0 - 10.5)
How to use
Before applying the enzyme agent, dehaired skins must be carefully rinsed after liming and subjected to preliminary de-ashing. Softening is performed in fresh solution at temperatures from 33 to 39 ℃ and within the range of pH = 7.5–9.5.
Depending on the desired quality and purpose of finished leather, as well as the type of the raw leather, the amount of the agent to be used may vary.
