The quest for efficiency and quality in textile manufacturing places significant emphasis on effective desizing. The enzyme alpha-amylase, identified by CAS number 9000-90-2, has emerged as a cornerstone for this process, offering a bio-based and highly effective method for removing starch-based sizing agents. For textile professionals, understanding the application and sourcing of this enzyme is crucial for optimizing production. This article serves as a guide for R&D scientists and procurement managers looking to leverage CAS 9000-90-2 amylase.

CAS 9000-90-2 refers to alpha-amylase, an enzyme renowned for its ability to catalyze the hydrolysis of α-1,4 glycosidic linkages in starch. In textile desizing, this means it efficiently breaks down the starch sizing applied to warp yarns, converting it into soluble dextrins and oligosaccharides. These smaller molecules are then easily washed away during subsequent rinsing steps, preparing the fabric for dyeing and finishing.

Optimizing the Use of CAS 9000-90-2 Amylase:

  • Temperature and pH: Our industrial amylase preparations offer optimal performance within a wide temperature range of 25-100°C and a pH range of 5.5-7.5. For specific applications like knit dyeing, a temperature of 40-70°C is often recommended, while denim washing might utilize slightly different parameters.
  • Dosage: Typical dosage recommendations for knit dyeing are 1-3 g/L (after dilution), and for denim washing, 3-5 g/L (after dilution), though precise amounts depend on the fabric, sizing type, and desired outcome. Consulting with your supplier for exact guidance is advisable.
  • Application Methods: The enzyme can be applied via various methods, including padding, jigger, or continuous steaming processes, ensuring versatility for different mill setups.
  • Environmental Benefits: Utilizing this enzyme promotes an eco-friendly approach by reducing the need for harsh chemicals and lowering water and energy consumption compared to traditional methods.
