XXII INTERNATIONAL CONGRESS IFATCC ITALIA, LAGO MAGGIORE STRESA, MAY 5-7, 2010
BIO-Preparation of cotton fabrics Enzymatic desizing Pad-Batch
T = 20° - 60°C
time = 3-12 hours
Bleaching Pad-Steam
washing washing
time = 3-20 minutes
T = 98° - 102°C

XXII INTERNATIONAL CONGRESS IFATCC ITALIA, LAGO MAGGIORE STRESA, MAY 5-7, 2010
For our study we used this preparation system largely applied by cotton companies
because of its
Practicatility Semplicity Versatility Easiness
Safety Cheapness
4
High quantity of impurities Lower costs of production Higher working speed
Poor quality of materials
XXII INTERNATIONAL CONGRESS IFATCC ITALIA, LAGO MAGGIORE STRESA, MAY 5-7, 2010
Insufficient degree of preparation

The efficacy of α-amilase enzymes could be influenced by different factors
pH value
Chemicals compatibility
