Bio scouring

Introduction :
Americos Bio-Scoured XL is a blend of pectinase and cellulase enzyme. It is used in bio-scouring process. It breaks down the pectin in the cotton and thus assists the removal of waxes, oils and other impurities. It is environmental friendly and gentle to fabric processing. It also saves water and energy.

The traditional strong alkaline process is a harsh treatment; it reduces fabric weight by 6 - 8%. Americos Bio-scoured XL makes it possible to scour effectively without affecting the fabric and the environment. Unlike traditional scouring Americos Bio-Scouring methods give fabric a soft start and gentle preparation for the subsequent stages of textile wet-processing.

Advantages :

• Softer fabric
• Reduced water consumption
• Reduced energy consumption
• Mild application conditions

Properties :

Appearance	Viscous liquid
Chemical character	Mixture of Pectinase and cellulase enzyme
Ionicity	Non-ionic
Solubility	Readily soluble in water
pH (1% solution)	7 ± 1
Application pH range	7.5 - 9
Application temperature range	55° - 60°C

Stability :

Hard water	Good, Ca2+ and Mg2+ ions increase the efficacy of enzyme
Acids	Poor
Alkalies	Stable in alkaline region from pH 7 to 9
Metal ions	Iron and copper ions are poisonous for enzymes

Compatibility :

Non-ionic surfactant	Generally very good
Anionic surfactant	Selective, some reduce the efficacy of the enzyme
Solvent based surfactant	Selective, some reduce the efficacy of the enzyme
Organic sequestrant	Generally good
Reducing / oxidizing agent	Reduce the efficacy of enzyme

Application Methods :
Americos Bio-Scoured XL can be applied by exhaust method.

Exhaust Application:(Jigger, Soft-flow m/c, Winch)

Americos Bio-Scoured XL	2 - 3 ml/l
Americos Anti-Crease Pro-76 A	0.5 - 1 g/l
Temperature	55° - 60°C
pH	7.5-9
Time	60 min

Add 2-3 g/l of Americos Extracta XL (emulsifying cum wetting agent), raise the temperature to 80°-85°C and run the machine for 30 minutes. Drain the above liquor at high temperature. Give one hot wash and one cold wash.

Storage & Handling Precautions :

• Store in cool place.
• Avoid storing in direct sunlight.
• The shelf life of Americos Bio-Scoured XL is one year if stored properly.
• The usual precautions in keeping chemicals away from eyes and skin should be observed.

Introduction :
Americos Ptex SL is an oxidatively stable proteolytic enzyme ideal for brightness and clean-up and cellulase inactivation after stonewashing of denim or bio-finishing of cellulosic goods. This enzyme cannot be used with normal bio-polishing and fading enzyme.

Advantages :

• Increase brightness
• Improves clean-up
• Enhance the contrast of abraded denim after cellulase treatment
• It works on low temperature
• Easy to use
• Americos Ptex SL oxidatively stable and may be used with products containing such as hydrogen peroxide or sodium perborate.

Properties:

Activity	20000 U/kg minimum
Appearance	Off- white
Size	80 - 100 mesh

Treatment Conditions:

Process Parameter	Operational Range
pH	7 - 10
Temperature	30°-60°C
Dosage	0.01 - 0.10% (owg)
Time	5 - 20 minutes

Americos Ptex SL reduces backstaining caused by cellulase treatment of denim. It enhances the interaction of residual cellulase which is bound to the fabric and is present in the wash liquor retained by the fabric after treatment.

Introduction :
Americos protease XL is proteolytic enzyme. It improves softness of woolen fabric when protease slightly degrades the protein core of the wool. It also reduces pilling and felting. Control of the process is paramount since over-reaction can lead to unacceptable weakness in the fabric. Americos protease XL performs well for finishing of wool.

Advantages :

• Enhances softness of woolen fabric
• Reduces pilling
• Reduces felting
• Environmental friendly

Americos protease XL can be used either before or after dyeing of the wool fabric.

Properties :

Appearance	Powder
Chemical character	Protease enzyme
Ionicity	Nonionic
Solubility	Readily soluble in water
pH (on 1% solution)	7 ± 1
Application pH range	8.0 - 8.5
Application temperature range	50 - 60°C

Stability :

Hard water	Good. Ca2+ and Mg2+ ions increase the efficacy of the enzyme
Acids	Poor
Alkalies	Stable in alkaline region from pH 7 to 9
Metal ions	Iron and copper ions are poisonous for enzymes

Compatibility :

Non-ionic surfactants	Generally very good
Anionic surfactants	Selective, some reduce the efficacy of the enzyme
Organic sequestrants	Generally good
Reducing / oxidizing agents	Reduce the efficacy of enzyme

Application Methods :
Americos protease XL is applied by following technique.

Americos protease XL	2 - 3 ml/l
Americos Anti-Crease Pro-76 A	0.5 - 1 g/l
Temperature	50 - 60°C
pH	8 - 8.5
Time	30 - 60 min

Storage & Handling Precautions :

• Store in cool place, avoid storing in direct sunlight.
• Americos protease XL should be stored at ambient temperature.
• The shelf-life of Americos protease XL is one year if stored under recommended conditions.
• The usual precaution in keeping chemicals away from eyes and skin should be observed.
