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:

  1. Selective action: Breaks down starch molecules without affecting cellulose fibers
  2. Low-temperature activity: Optimal performance at 50-65°C
  3. Rapid action: Complete starch hydrolysis in 30 minutes
  4. 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
