The process of transforming raw materials into finished textiles involves several critical steps, with desizing being a cornerstone for achieving optimal fabric quality. Traditionally, this involved harsh chemicals. However, the advent of enzymatic solutions, particularly the enzymatic hydrolysis of corn starch using alpha-amylase, has revolutionized the textile industry by offering a more sustainable and effective approach. For procurement professionals and R&D scientists, understanding these processes is key to making informed purchasing decisions.

Corn starch, widely used as a sizing agent due to its cost-effectiveness and film-forming properties, needs to be removed efficiently before dyeing and finishing. Enzymatic hydrolysis utilizes the catalytic power of alpha-amylase (CAS 9000-90-2) to break down the complex starch molecules into smaller, water-soluble dextrins and oligosaccharides. This process is highly specific, targeting the α-1,4 glycosidic bonds within the starch structure without affecting the cellulosic fibers of the fabric.

Advantages of Enzymatic Hydrolysis in Textile Desizing:

  • Fiber Integrity: Unlike chemical desizing, enzymatic hydrolysis gently removes starch without causing fiber damage, leading to improved fabric strength and a softer handle.
  • Environmental Friendliness: Enzymes are biodegradable and operate under mild conditions, reducing the need for high temperatures and harsh chemicals, thus minimizing effluent load and environmental impact.
  • Efficiency and Versatility: Our industrial amylase enzymes are designed to work efficiently across a broad range of temperatures (25-100°C) and pH levels (5.5-7.5), making them suitable for various desizing processes, including knit dyeing and denim finishing.
  • Cost-Effectiveness: While initial enzyme costs are a consideration, the overall process cost can be lower due to reduced water and energy consumption, fewer processing steps, and improved fabric quality leading to fewer rejects.
