Enzyme type Chemical Auxiliary Agent for textile
An Alpha-Amylase reduces processing costs without any damage to the fibers in textile processing.
Alpha-Amylase BAA-200 contains a hydrolyzing alpha-amylase made from submerged culture of Bacillus subtilis var. Through extraction and refining processes. It is a kind of endoamylase, which rapidly decreases the viscosity of the gelatinous starch solution by randomly hydrolyzing starch, glycogen and its degradation products within the alpha-1, 4 glycosidic bonds and produces soluble dextrins and oligosaccharides.
The powerful amylase activity of BAA200 breaks down starch to soluble polysaccharide in the textile which can easily be washed out. It enables the following benefits for textile industry: Mild, non-hazardous operating conditions, no damage to the fiber, considerably reduced water consumption, workload and processing costs.
|Activity||2,Â 000Â U/mlÂ (minimum)Â|
|Â SystematicÂ Name||ECÂ 22.214.171.124,Â 1,Â 4-alpha-D-glucanÂ glucanohydrolaseÂ|
|ProductÂ pH||5.5Â toÂ 7.0Â|
|SpecificÂ gravity||1.15Â toÂ 1.25Â g/ml|
EffectÂ ofÂ pHÂ
OptimumÂ pHÂ 6.0~6.5,Â stableÂ pHÂ rangeÂ 6.0~7.0,Â inactivatedÂ dramaticallyÂ withÂ pHÂ belowÂ 5.0.Â
Â EffectÂ ofÂ Temperature
OptimumÂ temperatureÂ rangesÂ fromÂ 60Â toÂ 90ÂºÂ C.Â AtÂ aÂ temperatureÂ rangesÂ fromÂ 70Â toÂ 90ÂºÂ C,Â theÂ reactionÂ speedsÂ upÂ whenÂ theÂ temperatureÂ risesÂ whileÂ theÂ enzymeÂ inactivationÂ alsoÂ speedsÂ up.Â
Â EffectÂ ofÂ Calcium
CalciumÂ ionÂ playsÂ aÂ protectiveÂ roleÂ forÂ theÂ stabilityÂ ofÂ enzymeÂ activity.Â TheÂ enzymeÂ activityÂ mayÂ disappearÂ completelyÂ withoutÂ theÂ presenceÂ ofÂ calciumÂ ion.Â TheÂ pHÂ rangeÂ ofÂ enzymeÂ activityÂ isÂ broadenedÂ withÂ theÂ presenceÂ ofÂ calciumÂ andÂ narrowedÂ withoutÂ it.Â
Protection salts should be added (0.025% calcium chloride, 0.4% sodium chloride) befor adding BAA-200. Typical dosage rate is 0.5 to 3 ml per liter of water. Exact dosage level should be determined after test according to the actual situation.
