Enzyme Washing process (Drak shade)

 

Introduction: Enzyme is a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. The enzymes under a chemical point of view is their high specificity or in other words, their ability to attack selectively a given substrate.

The action of enzyme during enzyme wash is to hydrolyze the cellulose, at first it attacks the having projecting fiber and hydrolyzed them. Then it attacks the yarn portion inside fabric and partly hydrolyzed the yarn portion and faded effect is produced.

Textile Enzymes called "Aurum". Enzymes (Greek for "in the cell" formerly also called ferments) are biologically the most important group of proteins. Aurum PC enzyme is used in washing technology.

Some features of Enzyme:

Enzyme wash is done on the garments made from heavy fabrics like jeans and denims.

• Enzyme Create bright to low effect:

1. Bright effect 
2.  Medium effect3
3. Light effect

•  Enzyme attacks as chemically not mechanically for this reason low damage/wastage then stone wash.
• Especially develop the "Bio-Polishing" effect of cotton/denim.
•  Enzyme improves the anti-pilling properties of garments.
•  Enzyme attacks more on the surface of the fabrics and gives a very smooth surface.

Procedure of Enzyme wash (Dark Shade):

The enzyme washing process of a batch size 60 kgs denim men's long pants (Trouser) is described below:

1.   De-sizing:

•  Lot weight (80 pcs) - 60 kg denim long pant.
•   Add water @ L : R = 1 : 9 - 540 Litre
• Machine Running.
• Temperature - 60°c.
• Add Desizing agent @ 0.6 gm / litre - 324 gm. 
• Add Detergent @ 0.8 gm / litre - 432 gm.
• Time - 10-20 mts.
•  Drop the liquor.
• Wash 1 time by cold water.

2.   Bio-Abrasion (mechanical and chemical action):

• Add water L : R = 1 : 8 - 450 Litre
• Temperature - 45°c.
• Add Acetic Acid - 0.6 gm / litre - 270 gm.
• Add Anti back staining - 0.6 gm / litre - 270 gm.
• Add Acid Enzyme - 2.00 gm / litre - 900 gm.
• Pumic stone - 20 to 100 %.
• Time (Depend upon the shade ) - 40-60 min.
• Increase temperature to 90°c and run 1 minute (enzyme killing).
• Drain the bath.
• Rinse Twice, each 3 minutes.

3.   Softening: 

•  Add water L : R = 1 : 8 - 450 Litre.
• Add Acetic Acid - 0.6 gm / litre - 270 gm. 
• Cat ionic Softener - 1 gm / litre - 450 gm.
• Temperature - Cold.
• Time - 15 to 20 mts.
• Drain the bath.
• Then unload the garments on trolley.

4.   Hydro extraction:

Hydro-extractor is used to remove excess water from the Garments.

5.   Drying:

• Load 60 kg garments to gas dryer.
• Temperature set - 75°c to 85°c.
• Run about 40 mts.
• After then run 10 mts in cold dryer.

6.   Delivery:

After drying, garment goes to quality section for quality checking and good one is delivered.
