In the sequence of textile finishing, the success of subsequent dyeing and printing depends heavily on the precision of the desizing stage. CRN PRELIZE AD is a highly stable alpha-amylase enzyme specifically engineered to rapidly and effectively degrade starch-based sizing agents on cellulosic substrates. This biochemical solution ensures that the sizing is removed without compromising the integrity of the fibers, leaving the fabric in its purest state for further processing.
Molecular Degradation and Selective Action
Starch-based sizing agents are inherently water-insoluble and difficult to remove via traditional washing. CRN PRELIZE AD targets the $\alpha-1,4$ glycosidic bonds within the long starch polymer chains, breaking them down into short-chain, water-soluble dextrins and sugars. This "selective" action ensures that only the sizing material is degraded, while the cellulosic fiber structure remains untouched, preserving the fabric's original tensile strength and durability.
Process Efficiency and Versatile Application
CRN PRELIZE AD is formulated to meet the high-speed demands of modern textile manufacturing. Its ability to remain active across a broad temperature spectrum allows for exceptional performance in various methods, from cold pad-batch to continuous desizing ranges. By harnessing enzymatic power, it significantly enhances the fabric's wettability (hydrophilicity), ensuring that subsequent bleaching and dyeing steps are uniform and highly efficient.
Key Advantages of CRN PRELIZE AD
High Enzymatic Potency: Rapidly eliminates starch residues even from the deepest pores of the fabric.
Fiber-Safe Processing: Unlike aggressive chemical desizing (acids or oxidants), it preserves the natural hand-feel and strength of the fibers.
Eco-Conscious & Sustainable: Its biodegradable nature reduces the environmental impact on wastewater and promotes energy-efficient processing.
Superior Stability: Maintains its catalytic efficacy under varying water conditions and across a range of pH levels.
