Recommendation for Efficient Enzyme Desizing

What is enzymatic desizing and what are the recommendation for efficient enzyme desizing

Desizing is the process of removing the size material from the warp yarns after the textile fabric is woven.

Enzymatic desizing is a traditional desizing procedure of degrading starch size on cotton fabrics using enzymes. Enzymes are multipart organic, soluble bio-catalysts, created by living organisms that catalyze chemical effect in biological process. Enzymes are quite specific in their act on a particular material. A small amount of enzyme is able to decompose a large quantity of the material.

Recommendation for efficient enzyme desizing

(Ref: BTRA – Bombay textile Research association)

  • Before enzyme de sizing cloth should be wetted with warm water.
  • Enzyme activity should be tested before use.
  • pH should be controlled.
  • Avoid copper made machines.
  • Enzyme treated cloth keep in a rider room.
  • Treated cloth wash with hot water.
  • Should be careful that enzyme above 70 degree centigrade temperature will be inactivate or damage.

 How enzyme activity depends on concentrate pH and temperature

  • Activity of enzyme increase with the increase of temp but up to certain limit then above that limitation activity decrease.
  • Enzyme stability decrease with increase of temperature.
  • Enzyme activity decrease with longer time.
  • Changing of pH rapidly changes enzyme activity and stability.
  • If concentration of enzyme increase then activity decrease.

Why enzyme desizing is popular?

  • No hydro-cellulose is formed, fabric strength remain changed.
  • The process is continuous and speedy.
  • The desizing capacity is more.
  • Less floor space is required.
  • Weight loss of fabric is less.

Description of continuous enzyme desizing process:

Normally when malt extract is used as the designing agent it takes about 3-4 hours for complete desizing to occur, but when stronger solutions of the extract are used to reduce the time within 5 minute.

Continuous Enzyme Desizing Process

In this case impregnated fabric has to put in the required pit the length of the floor of the pit should be equal to delivered impregnated cloth in 5 minute, so enzyme impregnated cloth, pit and washing machine should be synchronized with each other.
