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.
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.
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.
