Desizing agent

*DESCRIPTION:-

Amylotex H 320 is a concentrated thermo stable desizing agent which

Should be used for desizing fabrics sized with starch, starch derivatives or

Blends of starch plus other synthetic sizing materials.

The amylolytic power of Amylotex H 320 especially at high temperature

Allows rapid conversion of the starch size into dextrin's, which are easily

.removedby rising following impregnation with the product

* ADVANTAGES:-

1.Active at low & high temperature (45 – 90oC).

Temperature (oC) (Effect of temp. on the Relative Activity)

2.Has no side effect on textile fibers.

3.Wetting agents, detergents, non ionic surfactant, or solvent scours can be used with all applications of Amylotex H 320.

4. Full active in a range of pH (5 – 10).

*DOSAGE RECOMMENDATIONS:-

The following table is a general guide for determine

Dosages in various equipment and processing combinations.

Equipment / Dose / L R / Pick up
Winches / 0.15-0.3 g/L / 15-20
Circulatory vessels
and Autoclave
/ 0.4-0.5 g/L / 7.0-10
Jig / 0.75-0.9 g/L / 3.0-5.0

The activity of Amylotex H 320 is determined against an internal standard usingthe synthetic starch substrate Blocked P-Nitrophenylmaltoheptoside (BGNP). The resulting enzyme activity is expressed in EMA Reference Amylase Units (RAU).

*PROCESS CONDITIONS:-

Chelating agents should not be used with Amylotex H 320.

Water hardness and common salt increase the stability of the product Chemical Auxiliaries. Wettingagents,detergents, scouring agents or solvent scours can be used with all applications of Amylotex H 320 to enhance penetration and size swelling along with assisting in the removal of waxes, soils and synthetic sizing materials. Typically non –ionic surfactants are suitable for combination Lubricants are generally recommended to be used in combination with amylase enzymes

During desizing to reduce the formation of cease marks and streaks. The addition of Lubricants are especially recommended when deizing in rotary washers in jet dye

Machines, or in preparation for denimwashing.

Whenever auxiliary chemicals are used in conduction with desizing agents check to

Ensure that the auxiliaries are compatible with the product

*Packaging:-

Amylotex H 320 is available in 60, 120Kg (~ 132, 264 Lbs.) Plastic drams.

*Storage:-

To ensure extended shelf life, store Amylotex H 320 at35oC (87oF) or below in sealed container prolonged exposure of this product to elevated temperature and humidity levels will result in a loss of activity.

*SAFETY & HANDLING:-

Inhalationof dust and mists should be avoided .In case of contact with the skinor eyes, promptly rinse with water for at least 15 minutes.
