- Ferment ООО
Liquid agent based on bacterial α-amylase for de-sizing of textile materials.
Advantages
-
provides fast and complete decomposition of starch sizing with water soluble substances formation;
-
does not damage textile fibers, interacting only with starch size;
-
shows high efficiency at low and medium processing temperatures;
-
has high stability in hard water;
-
applied in periodic and semi-continuous processes;
-
reduces load on treatment facilities.
Composition
Amylase, purified water, calcium chloride, glycerine, tare preservative.
Mechanism of action
ENZYTEX AS hydrolyses α-1,4-glycoside bonds of starch, which is broken down to soluble dextrines and oligosaccharides and easily removed from the fabric surface by water.
Efficiency
| Resistance to: | |
|---|---|
|
Hard water |
good, calcium and manganese ions serve as amylase activators |
|
Metal cations |
bad, cations of heavy metals significantly reduce amylase activity |
|
Acids / alkali |
stable at pH from 5.0 to 8.0
optimal pH value 5.5–6.5 |
| Processing temperature |
working range 30–60 °C optimum range 40–60 °C |
| Compatible with: | |
|---|---|
|
Wetting agents / detergents |
good |
| Complex formers / stabilizers |
good, at optimal pH values |
| Reducing agents |
bad, reduce cellulase activity |
|
Oxidants |
bad, reduce cellulase activity |
