Desize 7X is a concentrated alpha-amylase enzyme which is used as a base for desizing fabrics sized with starch, starch derivatives, or blends of starch plus other synthetic sizing materials.
The strong power of Desize 7X allows for rapid conversion of the starch size into dextrins, which are easily removed by rinsing following impregnation with enzyme.
Consistent activity across pH range
Low temperature type for denim processing
Concentrated form ready for formulating
Process Conditions for the Desize Bath:
Operational Temperature: 90 - 140°F
Operational pH: 5.00 - 7.5
Usage Level: 0.2 - 0.4% o.w.g.
Operational Time: 5 - 15 minutes
Note: When using an alpha-amylase enzyme for desizing, it is recommended to use a nonionic detergent at 0.5% o.w.g. This will enhance the penetration and size swelling, along with assisting in the removal of waxes, soils, and other synthetic materials.
