Sizing Quality Monitoring and Process Automation
topic
Online sizing quality monitoring systems measure size concentration by viscosity or refractive index, yarn moisture by infrared sensors after drying, and size add-on by continuous weighing of sized versus unsized yarn streams, with closed-loop control systems automatically adjusting squeeze roller pressure, size box concentration, and drying temperature to maintain all quality parameters within defined specification limits throughout production.
Role
Maintains consistent sizing quality throughout long production runs by continuously measuring and correcting the key process variables that determine size add-on and film quality, preventing the sizing defects including add-on variation, incomplete drying, and yarn-to-yarn adhesion that cause weaving efficiency reduction and fabric quality problems that would otherwise require manual operator monitoring and adjustment.
