The Energy Challenge in Textile Pre-Treatment
Traditional desizing processes require temperatures of 80–95°C for extended periods, consuming enormous amounts of energy. With rising energy costs worldwide, textile manufacturers are seeking more efficient alternatives.
Enzymatic vs. Traditional Desizing
| Parameter | Traditional | Enzymatic (Grozyme AML) | |-----------|------------|------------------------| | Temperature | 80-95°C | 50-65°C | | Duration | 60-90 min | 30-45 min | | Energy cost | High | 40% lower | | Starch removal | 85-90% | 95-98% | | Fiber damage | Possible | Minimal |
How Grozyme AML Works
Grozyme AML is a bacterial alpha-amylase enzyme specifically designed for textile desizing:
- Selective action: Breaks down starch molecules without affecting cellulose fibers
- Low-temperature activity: Optimal performance at 50-65°C
- Rapid action: Complete starch hydrolysis in 30 minutes
- Bio-degradable: Zero residual environmental impact
Implementation Guide
Cold pad-batch method (most energy efficient):
- Grozyme AML: 3-5 g/L
- Growet LFN (low-foam wetting agent): 1-2 g/L
- pH: 6.0-7.0 (natural, no adjustment needed)
- Temperature: 50°C
- Dwell time: 4-8 hours (overnight batch)
Continuous method:
- Grozyme AML: 5-8 g/L
- Temperature: 60-65°C
- Contact time: 30-45 minutes
ROI Calculation
For a mid-size textile mill processing 50 tons/day:
- Energy saving: €15,000-20,000/year
- Water saving (fewer rinse cycles): 25%
- Chemical cost: Comparable to traditional methods
