Amylase, Liquid

Aquazym®

Products in the Aquazym®  family effectively break down and remove starch-based sizing agents. They're available in a range of concentrations. Oxidative desizing methods can negatively affect the cellulose. Aquazym® products only target the starch, so don't impact the fabric strength.

Key Benefits
  • Improves fabric quality

    The specific enzymatic action of products in this family desizes without damaging fibers. The result is improved fabric quality.

  • Improves wettability

    Poor wettability leads to uneven dyeing and poor batch-to-batch shade reproducibility. It also causes problems during printing. Products in this family deliver full and uniform removal of size polymers. That results in wettable fabric that can absorb the dye. 

  • Available in wide pH and temperature ranges

    The products in this family are available in a wide temperature and pH range, so you can find a product to suit your process and conditions. 

  • Reproducible performance

    The enzymatic action of products in this family is easier to control than alternative desizing methods. That helps you achieve reproducible performance. 

  • Improves worker safety

    The enzymatic products in this family allow you to eliminate harsh chemicals from your desizing process. That leads to improved worker safety at your mill. 

  • A more sustainable solution

    This product is both biodegradable and renewable. It saves water and energy as well as reducing chemical loads in your effluent. That makes it a more sustainable solution that can also improve worker safety in your mill.

How amylases work in starch desizing at textile mills

Starch is the most common sizing agent in textile manufacturing. Amylases target and break down starch without harming the yarn. The result is highly efficient and effective desizing.


Textile manufacturers use a process called sizing to aid the weaving process. Size forms a coating on warp yarns. This coating helps them to withstand tension during weaving and reduce breakage. Once this process is complete, the textile needs to go through a desizing process. Desizing removes the coating before bleaching or dyeing. 

For more than a century, starch has been the most common sizing agent for fabrics. Textile mills use amylase enzymes to desize woven fabrics. That's because of their highly efficient and specific action. They desize the yarn without harming it. 

Starch molecules are formed of long chains of sugars. That makes them difficult to remove from the yarn. Amylases break long-chain starch molecules into short-chain dextrins. The short-chain dextrins are much easier to remove, which results in more efficient and complete desizing.
