CRN FLOW FK is a sophisticated liquid alkali buffer designed to optimize the fixation of reactive dyes on cellulosic fibers. By preventing pH fluctuations and minimizing dye hydrolysis, it ensures maximum dye exhaustion and color fastness, providing a cleaner and more efficient alternative to traditional powdered soda ash.

Why It Should Be Preferred?

• Stabilized pH Environment: Acts as a powerful buffering agent to maintain the exact alkalinity required for covalent bonding between dye and fiber.

• Minimized Dye Hydrolysis: Redirects reactive dye molecules toward the fiber rather than reacting with water, significantly boosting dye yield.

• Automated Dosing Compatibility: Its liquid form allows for precise, automated injection into dyeing machines, eliminating manual weighing errors.

• Enhanced Rinsability: Dissolves perfectly in the dye bath, making it much easier to wash off than solid alkalis, which leads to shorter processing cycles.

• Operational Savings: Reduces the overall consumption of water, steam, and time by optimizing the fixing and rinsing stages.

Areas of Usage

• Exhaust Dyeing: Primary fixing agent for cotton knits and yarns in jet and winch dyeing machines.

• Continuous Dyeing: Ideal for pad-dyeing processes requiring a stable and concentrated alkali source.

• Delicate Fiber Processing: Suitable for viscose, linen, and modal where precise pH control is vital to prevent fiber damage.
