Textile Far - Infrared Radiation Heating Tester

The Textile Far-Infrared Radiation Heating Tester is designed to accurately measure the far-infrared properties of textile materials, including fibers, yarns, fabrics, nonwovens, and finished products. It provides precise, non-destructive testing of emissivity and surface temperature rise, supporting research, development, and quality control of functional and heat-retaining textiles.

Application

Measurement of far-infrared emissivity and thermal radiation properties of textile fibers, yarns, woven and nonwoven fabrics.

Evaluation of heat-retention and thermal comfort performance of apparel textiles, bedding, and industrial fabrics.

Assessment of performance for far-infrared functional textiles used in medical, sports, or therapeutic applications.

Quality control of heat-insulating, warming, or protective textiles for automotive, aerospace, and construction industries.

Research and development of infrared-emitting fabrics and fabrics with thermal regulatory properties.

Comparative testing of different textile treatments, coatings, or fiber blends on far-infrared radiation performance.

Support for product certification and compliance testing related to thermal and radiative properties.

Technical Parameters

Accessories

Standard blackbody reference plate

Sample hot plate

Far-infrared radiation measurement system

USB and network cables

Instrument software and user manual

Optional calibration kits and additional blackbody plates

Test Procedures

Place the standard blackbody reference plate on the hot plate and set the required temperature.

Place the textile sample on the hot plate after the blackbody measurement is completed.

Allow both to reach a stable temperature.

Measure far-infrared radiation intensity of the blackbody and the sample.

Calculate the sample’s far-infrared emissivity as the ratio of its radiation intensity to that of the blackbody.

For temperature rise measurements, irradiate the sample with a constant far-infrared source and record the surface temperature change over time.

Repeat for multiple samples or temperature settings to generate comprehensive emissivity data.

Maintenance Information

Regularly clean hot plates, blackbody surfaces, and sample holders to maintain accuracy.

Periodically inspect and calibrate the far-infrared measurement system.

Check touchscreen and interface connections for proper operation.

Keep the instrument in a dry, dust-free environment to prevent degradation.

Apply software and firmware updates to maintain performance and measurement precision.

Avoid mechanical shocks to the measurement system and optical components.
