As part of the Biouptake project, a thermal camera prototype was tested at CENTEXBEL’s facilities in November. The objective was to evaluate the feasibility of using thermal imaging for real-time yarn temperature monitoring during the stretching process.
IRIS, with expertise in advanced monitoring solutions and process optimization, deployed the camera to assess its accuracy in tracking temperature variations along different points of the yarn stretching system. CENTEXBEL, a key research center in textile innovation and materials science, provided its facilities and technical expertise to analyze the integration of thermal imaging in their processes.
Testing and Findings

• Camera Positioning and Installation: The initial setup required adjustments to ensure optimal positioning within the stretching line. Alternative measuring points were identified to improve monitoring accuracy.
• Temperature Measurements: The camera recorded yarn temperatures at different points, revealing significant variations and rapid cooling after separation from the rolls.
• Validation with Thermocouples: A comparative test between the IRIS thermal camera and CENTEXBEL’s thermocouples confirmed that both methods provided comparable results, though further verification is needed to enhance accuracy.

Next Steps. To improve the effectiveness of the monitoring system:

• IRIS will refine the camera calibration, develop a more adaptable magnetic mounting system, and enhance data storage capabilities for continuous monitoring.
• CENTEXBEL will further analyze its machine temperature profiles to ensure the process conditions align with expected reference values.
