MASZYME NE is a powder neutral cellulase enzyme preparation, which is used for receiving decoloration effect on jeans/denim garments and fabrics as a substitute to the "stone-wash" process traditionally used with special abrasion stones. It can be used also together with abrasion stones in a lower load. MASZYME NE is superior to acidic cellulase preprarations with respect to indigo back staining problems.

Storage	Keep in cool and dry place in tightly closed packages. When properly stored shelf life is at least 12 monthes.

1. MASZYME NE is a neutral cellulase enzyme preparation, designed for producing premium in high contrast, faded look and a softer handles, with low back-staining.

2. MASZYME NE is effective in a broad pH range compared to conventional whole cellulase preparations (5.0-7.5).

3. The product is formulated with buffer salts which enable optimum pH range for the neutral cellulase effectiveness.

4. MASZYME NE is effective in a wide temperature range (40-60ºC).

5. MASZYME NE has a linear dose/response effect. A wide range of abrasion effects from low to high is easily achieved by changing the dose of the product, with and without abrasion stones.

6. MASZYME NE is recommended also for bio-polishing of cellulosic fabrics, with lower back staining effect. Produces a smoother and softer fabric with less pilling after repeated laundries.

7. Saves handling problems and storage space of big amounts of abrasion stones.

8. Lowers noise problem in the mill.

9. Lowers machine amortization.

10. Lowers damages to garments.

11. Can be used in combination with abrasion stones with a lower load of the pumic stones.

I. MASZYME NE treatment without abrasion stones:

1. Load desized garments and fill machine with warm water to liquor ratio 1:5 - 1:10.

2. Adjust temperature to 45-60ºC (optimum is 50-55ºC)

3. Add 0.5-2% o.w.g. of MASZYME NE

4. Treat for 30-90 minutes.

5. Drain solution, rinse immediately hot and cold.

6. Wash with 1-2 gr/l MASTONE SC at 40-60ºC.

7. Rinse cold, and continue with softening procedure. Softening is recommended with an MASTONE BS.

II. MASZYME NE treatment with abrasion stones - combined process

1. It is possible to combine the MASZYME NE treatment with abrasion stones.In this case a lower dosage of MASZYME NE is needed. (0.25 – 1.0% o.w.g.)

2. The procedures is similar to the stone-less procedure mentioned above. The quantity of abrasion stones can be reduced compared to the quantity needed when stone washing without cellulase enzymes.

1. The efficiency of MASZYME NE depends on the temperature and pH of the treatment liquor. If the pH is out of the optimum, the temperature should be kept on the lower side.

2. It is recommended to check the effectiveness of MASZYME NE by trials with every specific denim quality.

3. After the enzyme treatment drain the bath and wash immediately. Fabrics should not stay too long time with enzyme residues as it can cause deterioration of the fabric strength.
