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:
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.
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:
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.

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.
Americos Protease XL 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 :

Americos Cellscos 450 AP (Denim fading enzyme) Introduction : Americos Cellscos 450 AP is a highly concentrated acid cellulase enzyme (NCU activity - 2,15,000) produced by genetically modified strains of Trichoderma Reesei. It is cost effective for denim material.
Americos Cellscos 450 AP/ Acid Cellulase Powder aggressively hydrolyses yarn surface by attacking the 1, 4 beta glycoside linkage of cellulase, yielding soluble products such as short-chain polysaccharides and glucose. This action loosens the indigo dye layer on yarn surface, which is subsequently more easily removed by mechanical action of the machine. After desired degree of abrasion is achieved, the deactivation of enzyme is recommended.
Advantages of this acid powder:
High contrast with acceptable strength loss
Better and bigger granular effect
Even abrasion
Improves touch and drape of garments

Americos Bio-Gloss XL is a bio-polishing enzyme. The term bio-polishing refers to the removal of fluffy fibers / protruding fibers from the surface of fabric by enzymatic hydrolysis. Such bio-polishing results in clear fabric surface. Americos Bio-Gloss XL has three different enzyme activities: Exo-Cellulase, Endo-Cellulase and ß-Glucosidase which makes Americos Bio-Gloss XL especially suitable for all kinds of cellulosic fibers.
Americos Bio-Gloss XL enzymatically hydrolyses the protruding fibers and loosen 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.
