Introduction :
Americos Amylase 180 is a desizing agent based on bacterial alpha amylase. It is a unique blend of thermal stable alpha-amylase and lubricant to remove most of the size materials from denim garment. This unique combination prevents the formation of unwanted creases, streaks, lines and crack marks during desizing process. It can be used to degrade the following size materials and their combinations:

• Starch
• Starch / Polyvinyl alcohol
• Starch / Polyvinyl alcohol / Carboxyl Methyl Cellulose (CMC)
• Starch / Polyvinyl alcohol / Acrylates

Properties :

Stability :

Compatibility :

Application Methods :


Exhaust application (Jigger, Soft-flow m/c, Winch, Wash-wheel)

2) Continuous Application (Jigger, Soft-flow m/c, Winch, Wash-wheel)

Storage & Handling Precautions :

• Store in a cool place
• Avoid storing in direct sunlight
• The shelf life of Americos Amylase 180 is one year if stored below 40°C
• The usual precautions in keeping chemicals away from eyes and skin should be observed

Introduction :
Americos Amylase 380 enzyme is a concentrated thermostable bacterial amylase which should be used as a formulating base for desizing fabrics, sized with starch, starch derivatives, or blends of starch and other synthetic sizing materials. The strong amylolytic power of Americos Amylase 380 enzyme - especially at high temperatures - allows rapid conversion of the starch size into dextrins, which are easily removed by rinsing following impregnation with enzyme.

Americos Amylase 380 enzyme has long been the industry standard for quality, consistency, and stability. The formulation of the enzyme was designed to accommodate further addition of a variety of chemical auxiliaries in order to assist our customers in differentiating their desizing product line.

Americos uses state-of-the-art biotechnology production methods and this product contains enzyme (s) produced by a genetically modified organism.

Advantages:

• Concentrated for easy formulation into differentiated textile desizing products
• Active at high temperature
• Tolerates live steam

Typical Characteristics:

The activity of Americos Amylase 380 enzyme is determined against an internal standard using the synthetic starch substrate blocked p-Nitrophenylmaltoheptoside (BGNP).

The resulting enzyme activity is expressed in Themostable Textile Amylase Units (TTAU)

Process Conditions:
Chelation:
Chelating agents should not be used with Americos Amylase 380 enzyme. Water hardness and common salt increase the stability of this enzyme.

Chemical auxiliaries:
Wetting agents, detergents, scouring agent, or solvent scours can be used with all applications of Americos Amylase 380 enzyme to enhance penetration and size swelling, along with assisting in the removal of waxes, soils, and synthetic sizing materials.

Typically, non-ionic surfactants are suitable for combination with enzymes whereas anionic and cationic surfactants may disrupt enzyme activity.

Lubricants are generally recommended to be used in combination with amylase enzymes during desizing to reduce the formation of crease marks and streaks. The addition of lubricants is especially recommended when desizing in rotary washers, in jet dye machines, or in preparation for denim washing.

Whenever auxiliary chemicals are used in conjunction with desizing enzymes, check to ensure that the auxiliaries are compatible with the enzyme.

Storage & Handling Precautions:

• Store in a cool place, preferably below 25°C
• Avoid storing in direct sunlight
• Prolonged storage above 30°C should be avoided
• The usual precaution for chemicals should be observed
