Appearance	Creamy powder
CAS No.	9012-54-8
IUB-No	EC 3.2.1.4

Advantages :

• Provides excellent stone washing effects without prewashing with desizing enzymes.
• Gives fast and even abrasion effect with good anti-back staining effect.
• Reduces processing time and improves production efficiency.
• Saves time and energy cost (50% less water and energy consumption, 15% less electric power)
• High level of surface modifications can be achieved without pumice stones, which reduce machine wear and tear and fabric damages.
• Eco-friendly and Bio-degradable.

Application Parameters:

Product Application:
In order to gain maximum effectiveness of Americos D9E4 under optimum condition, It is recommend to add some acetic acid to adjust the pH to 6.5 before enzyme washing as the alkalinity on the denim fabric might be high.

Application for Americos D9E4 is as follows:

Americos D9E4 dosage	0.5-1.5% w.o.f (depending on the finishing effect)
Non-ionic surfactant (optional)	0.5-1.0% w.o.f
Bath ratio	8:1-15:1
Processing time	45-70 minutes
Temperature	40-55 ° C
pH value	6-7

Inactivation:
Inactivation must be carried out after treatment. Either alkaline rinse with 1-2g/l sodium carbonate under the temperature of 80 ° C by raising pH to > 10 for 10 minutes or the use of bleaching agents will terminate the enzyme reaction.

Storage & Handling Precautions:

• Store in cool place and avoid storing in direct sunlight
• The shelf life of Americos D9E4 is 6 month under recommended storage
• The usual precautions in keeping chemicals away from eyes and skin should be observed

Introduction :
Americos Bio-Sharp A1 is a concentrated, engineered component cellulase. It is produced by neutral process and biodegradable. The product is designed to be formulated in to products that fill the needs of fabric and garment processer. It gives consistently good performance and it has excellent shelf life in normal room temperature. Americos Bio-Sharp A1 especially suitable for all kinds of cellulosic fibers.

Americos Bio-Sharp A1 enzymatic hydrolyses the protruding fibers and loosens their ends. The removal of such hydrolyzed fibers requires mechanical agitation. Hence, the machines like soft-flow, jet and wash wheel, which produce mechanical agitation, are more suitable for bio-polishing.

Advantages:

• Excellent fabric surface polishing
• Reduced pilling
• Improved softness and smoothens
• Improved drape
• Preserve more fabric strength
• Minimize shade change

Properties:

Appearance	Liquid
Odor	Slightly fermented odor
Activity	5372 ATU /g (minimum)
Solubility	Readily soluble in water
pH (1% solution)	7 ± 1
Application pH range	4.5–5.5
Application temperature range	45°–55°C

Stability:

Hard water	Good
Acids/ Alkalies	Active and stable form in pH range 4.5–8.5
Metal ions	Metal ions are poisonous for cellulase

Compatibility:

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

Applications:
Americos Bio-Sharp A1 is applied on fabric / garment in soft flow, rotary drum washer with high mechanical action.

Americos Bio-Sharp A1 specially designed for bio-finishing I. e, softening, surface fiber removal, de-pilling, off cotton and other cellulosic fabrics and garments.

Recipe:

Americos Bio-Sharp A1	: 0.7–1% (owg)
Americos Anti-Crease Pro 76A	: 0.5–1 g/l

pH and Temperature
The combination of pH and temperature has the most impact on performance of Americos Cellstone TL.


Americos E2T3 FadXx activity vs. pH, measured with a synthetic sustrate at 55°C and 65°C.

Note: These graphs are made with a synthetic substrate. Therefore, performance in actual biofinishing application can differ from the shown data.

Americos E2T3 FadXx can be used in a broad temperature range of 40 to 70°C within a pH of 3.5 to 5.5. Recommended standard conditions are temperature of 55 - 60°C at pH 4.5 - 5.0.
