Americos Amylase 180 (Desize, Alpha - amylase Enzyme)

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:
Properties :
Appearance Liquid
Chemical character Bacterial amylase enzyme stabilized with buffer
Ionicity Nonionic
Solubility Readily soluble in water
pH (on 1% solution) 7 ± 1
Application pH range 5 - 8
Application temperature range 60oC

Stability :
Hard water Good. Ca2+ and Mg2+ ions increase the efficacy of the enzyme
Acids Good to pH 5 to pH 7
Alkalis Stable in alkaline region from pH 7 to pH 9
Metal ions Iron and copper ions are poisonous for enzymes

Compatibility :
Nonionic surfactants Generally very 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

Application Methods :
Exhaust application (Jigger, Soft-flow m/c, Winch, Wash-wheel)
Americos Amylase 180 : 1 - 2 g/l
Americos Anti-Crease Pro-76 A : 0.5 - 1 g/l
pH : 6 - 7
Time : 30 - 60 min.

The actual concentration of Americos Amylase 180 depends on material to liquor ratio, agitation produced in m/c, cracking potential of sizing ingredients and equipment being used Drain the above liquor; give one hot wash and one cold wash. Alkaline washing with soda ash improves the removal efficiency of degraded sizing material.

2) Continuous Application (Jigger, Soft-flow m/c, Winch, Wash-wheel)
Americos Amylase 180 0.5 - 1% (owg)
pH 5.5 - 6.5
Impregnate the fabric at bath temperature between 70 - 80°C for 80 - 100% pick-up. Then steam it for 3 - 5min at 100°C In case of high temperature steaming, treat it for 1 - 2 min at 110C - 130°C.

Americos Amylase 345 (Wide range law temperature de-size enzyme)


Introduction :
Americos Amylase 345 is a desizing agent based on bacterial alpha amylase. It is a mixture of highly concentrated alpha-amylase, wetting agent and lubricant to convert most of the sizes viz. starch, starch derivatives, synthetic sizes and their blends into water soluble products. Specifically it can be used for the following sizing materials and their combinations:

Advantages: Americos Amylase 345 has three different types of actions. The built-in wetting agent ensures proper penetration of enzyme in the textile material. The enzyme then converts the starch sizes in to soluble dextrin products, which can be easily removed in the subsequent washings. Moreover, the in-built lubricant reduces fiber to fiber and fiber to metal friction. This unique combination prevents the formation of unwanted creases, streaks, lines and crack marks during desizing process.

Physical Property
Appearance Viscous liquid
Chemical character Blend of amylase enzyme and non-ionic surfactants
Ionic nature Non-ionic
pH (on 1% solution) 5.5 – 6.5
Application pH 6 - 7
Application temperature 30 - 60°C

Stability
Hard water Good, Ca2+ and Mg2+ ions increase the efficacy of the enzyme
Acids Good from pH 5 to 7
Alkalis 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 sequestrates Generally good
Reducing / oxidizing agent Reduce the efficacy of enzyme
Application Methods
Americos Amylase 345 can be applied by any one of the following techniques.

a) Exhaust application (jigger, soft-flow m/c and winch)
Americos Amylase 345 1 - 2 ml/l
Temperature 30-60°C
pH 6 -7
Time 30 - 60 min

After the treatment, drain the liquor; give one hot wash and then one cold wash. Alkaline washing with soda ash improves the removal efficiency of degraded sizing material.

b) Exhaust application (wash-wheel)
Americos Amylase 345 1% (owg)
Temperature 30-60°C
pH 6 -7
Time 30 - 60 min

First, raise the temperature of bath to 30 - 60oC. The machine should run for a minute to ensure proper mixing of chemicals. Adjust pH 6 - 7.

Thereafter, garment should be loaded. The desizing time can be varied from 30 - 60 min depending upon the type of fabric and chemical dosage.

3) Semi-continuous application (pad-batch process)
Americos Amylase 345 3 - 5 ml/l
pH 6 -7

Impregnate the fabric at 30-60°C for a pick-up of 80 - 100%. Store the fabric for 8 - 12 h; give one hot wash with soda ash, one plain hot wash and one cold rinse.

Americos Amylase 380 (Thermo stable bacterial a-amylase)


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: Typical Characteristics:
Activity 65000 TTAU/g (minimum)
Appearance Brown liquid
Specific gravity 1.1
pH 6.0-8.0
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)

Temperature 40°-110°C

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.
