Alpha Amylase Textile Desizing Enzyme For Fabric And Garments Pre - Treatment
Brief Introduction:
(1) desizing agent based on fungall alpha amylase.
(2) unique blend of heat - stable alpha - amylase and lubricant to remove most of the size materials from denim garment.
(3) This unique combination prevents the formation of unwanted creases, streaks, lines and crack marks
Advantages:
1. Concentrated and easy operation
2. Active at low / medium / high temperature
3. Tolerates live steam
Application Range:
| Composition | Bacterial amylase enzyme stabilized with buffer |
Ionic character | Non-ionic |
| Solubility | Readily soluble in water |
| pH (on 1% solution) | 5.5 - 7.5 |
| Application pH range | 5.0 - 8.0 |
| Application temp range | 40 - 100 ℃ |
| Pad - steam desizing | Suitable |
| Cold pad - batch | Suitable |
Overflow;Jig dyeing;Hank dyed | Suitable |
Stability:
| Hard water | Good. Ca2+ and Mg2+ ions increase the efficacy of the enzyme |
| Acids | Good to pH 5 to pH 7 |
| Alkalis | Stable in alkaline region from pH 7 to pH 9 |
| Metal ions | Iron and copper ions are poisonous for enzymes |
Compatibility:
| Nonionic surfactants | Generally very good |
| Anionic surfactants | Selective, some reduce the efficacy of the enzyme |
| Solvent based surfactants | Selective, some reduce the efficacy of the enzyme |
| Organic sequestrants | Generally good |
| Reducing / oxidizing agents | Reduce the efficacy of enzyme |
Formulation Ways:
| CONTENT (%) | |
| Amylase | X |
| “A” Liquid | 100-X |
NOTES:“A” liquid contents 10% vaccum free flow salt, 10% sorbitol (70%) and 0.2-0.3% sodium benzoate or 0.1-0.2% Casson
Steps of Dilution:
1. Prepare the “A” liquid
2. Control pH to 6.0-6.6 by sodium hydroxide or acetic acid
3. Appropriate amount of amylase
4. Deionized / distilled water to 100%
Storage:
Store in a cool place
Avoid storing in direct sunlight
The shelf life is one year if stored below 40 ℃
The usual precautions in keeping chemicals away from eyes and skin should be observed
