Enzyme for high temperature desizing of textile materials

Product Name: Alpha Amylase DHK Q189

Use:
Enzyme for high temperature desizing of textile materials.

Properties:
(1) is suitable for desizing at temperatures of 60 - 100deg.
(2) is very fast acting at high temperatures.
(3) is suitable for the removal of sizes on the basis of potato starch, corn starch, manioc, carboxylmethyl cellulose.
(4) very low loss of activity when heated with life steam.

Chemical Characteristics: Bacterial Amylase

Technical Data:
Appearance: Brown liquid
Density: Approx. 1.1g/ml
pH-value:   5.5 - 6.5
Dissolving procedure: Dilute with water
Shelf life: 6 months in closed original containers at temperature below 25deg.

Application:
Alpha Amylase DHK Q189 is used to remove starch and starch-containing sizes from textile material.

The high temperature stability of the product permits desizing temperatures of 60 - 100° C. Starch depolymerisation into small degradation products easily removable by scouring occurs in 1 - 2 min. Continuous procedures such as pad-steam procedures, therefore, are possible.
For extremely high speeds steam temperatures up to 115° C may be used to extremely fast heat the textile material which has been padded with the enzyme solution.
