Is enzyme washing most popular wash?

Enzyme wash

Enzyme are proteins produced by living organism. All organisms a wide rage of enzyme to accomplish necessary biological tasks. It is a process that removes fuzz and eliminates piling in cellulose garments. The enzyme performs a controlled hydrolysis of cellulose fibres is order to modify the fabric surface. This keeps garments looking new after repeated washes.

Action of enzyme:

1. Its hydrolysis cellulose, at first it attacks having projecting fibre and hydrolysis them.

2.Then it attacks the yarn portion inside fibre and partially hydrolysis yarn portion. As a result the colour comes out from the yarn portion and faded effect is produced.  

Types of enzyme:

There are two of enzyme such as, acid enzyme and neutral enzyme.

Acid enzyme

- acid enzyme mainly in liquid form.
- PH 4.5 to 5.5.
- tempt, 40 to 55 degree Celsius.
-Time 20-40 min.
- enzyme effect comes with short time.
- bleeding and straining possible is high.

Neutral enzyme

- neutral enzyme mainly in liquid or powder form.
- PH 6 to 7.
- tempt, 40 to 60 degree Celsius.
-Time 40 to 90 min.
- enzyme effect comes slowly.
- bleeding and straining possible is less then acid enzyme.

Recipe:

Pumic stone – 20 to 200%
Enzyme – 0.6 to 2 ml
PH – 6.5 to 7
M:L – 1:10
Time – 90 min
Temp - 50˚C.

Process Flow Chart of Enzyme Wash:


Batching
M/C loaded water and garments
Add desizing agent and treat about 15 min at 70˚c tmp.
 Drop the liquor
Again loaded the m/c
Add Pumic stone and enzyme
Temp. Raise at 50˚c
Run about 30 min
 Drop the liquor
Again m/c loaded
Add reagent and soda ash (ph -9-10)
M/C run at 80˚c about 5 min
      Drop the liquor
M/C loaded and add sodium hypochlorite 5 to 10 m/l
Continuous treat about 10 min. at 60˚c.
Add sodium meta bisulphite 1 m/l .
M/C run at 50˚c about 10 min
Drop the liquor
Bath drop and m/c loaded add softener 0.5-1% treat about 5 min
      Drop the liquor       
              Hydro extractor
        Drying
       Delivery
