Enzymes for textile desizing
Amylase-based desizing is relevant when starch is present in the size formulation. Identify the size before selecting a preparation: not every sizing material is a substrate for amylase.

Understand the mechanism and the process
Desizing combines treatment with removal of the resulting material. Evaluate the enzyme stage and the washing stage together. Good enzyme selection cannot compensate for an unverified size composition or an inadequate removal step.
- Starch-containing size
- Amylase treatment
- Wash and check
Plan a useful evaluation
- Confirm the fiber, fabric construction and known size composition.
- Document bath conditions, contact time, wetting and washing sequence.
- Compare residual size after treatment using a consistent agreed method.
- Check absorbency and fabric quality alongside size removal.
What needs confirmation?
Use the preparation-specific operating guidance. A temperature range from another amylase is not a validated limit for the candidate under review.
Will an amylase remove all synthetic size?
Do not assume so. Identify all size components and review a suitable treatment sequence.
