ENZYME WASH PROCESS



Enzyme wash

ENZYME WASH

Enzymes are bio chemical substances that behave as catalysts toward specific reactions. What makes very interesting the enzymes under a chemical point of view is their high specificity or in other words, their ability to attack selectively a given substrate.
Among the two traditional enzymes used in the treatments of denim garments (amylase to hydrolyze starches and cellulose to degrade in different way's cotton's cellulose) there is another enzyme that can be employed to attack selectively the molecule that constitutes the blue indigo colour resulting ineffective on other kind of dyes.
The action of enzyme during enzyme wash, it hydrolysis the cellulose, at first it attacks the having projecting fiber and hydrolyzed them. Them it attacks the yarn portion inside fabric and partly hydrolyzed the yarn portion and fadded affect is produced.
Mainly two types of enzyme used in Bangladesh. One is Acid Enzyme (liquid) and another is Neutral Enzyme. Neutral Enzyme is two types -a) Powder form b) Liquid form ie, SL Enzyme.

ACID ENZYME

Acid enzyme colour is slightly brown.
pH range is 4.5 to 5.5
Temperature -40°c -55°c.
Time required 25 mts to 50 mts.
Enzyme affects come within short time.
Staining/Bleeding occurs more in garments.
Production high.

NEUTRAL ENZYME

Enzyme is slightly white powder form.
pH range is 6 to 7.
Temperature -40°c -60°c.
Time required 40 to 70 mts.
Enzyme affects come slowly.
Less staining/bleeding on garments.
With pumic stone comes good affect/abrasion on garments.
In dark shade enzyme affect comes good.

SL ENZYME

SL enzyme is liquid form.
pH range is 6 to 7.
Temperature range 40°c -60°c.
Time required 45 to 80 mts.
Enzyme affects come slowly.
Less staining/bleeding on garments.
With pumic stone come better affect.
In dark shade enzyme affect comes good.

ENZYME WASH

Enzyme wash is required for the following reasons:
To remove the size materials from the garments.
To remove the starch presents on the garments fabrics.
To achieve the high low abrasion (stone affect) on garment and seam abrasion in sewing area.
Enzyme attack as chemically not mechanically for this reason low damage/wastage then stone wash.
For soft feeling to wear the garment.
To achieve the buyer reference sample.
To increase the colour fastness & rubbing fastness.
Especially develop the "Bio-Polishing" affect of cotton/denim.
Enzyme improves the anti-pilling properties.
Enzyme attacks more the surface of the fabrics and gives a very smooth surface.
