Textile Far Infrared Radiation Temperature Rise Tester

The Textile Far Infrared Radiation Temperature Rise Tester is a high-precision analytical instrument specifically engineered to evaluate the far-infrared thermal performance of functional textiles. By simulating infrared radiation exposure and monitoring the resulting thermal response, this tester allows you to determine the temperature rise efficiency and heat-retention capabilities of advanced materials. It integrates a standardized 150W radiation source with high-speed thermal sensors to provide you with objective, repeatable data on how a fabric interacts with infrared energy—a critical metric for verifying the therapeutic or "self-heating" claims of modern performance textiles.

Applications

Textile Far Infrared Radiation Temperature Rise Tester is used for various textiles including fibers, yarns, fabrics, nonwovens, and their products. It employs temperature rise testing to determine the far-infrared performance of textiles.

FAQ

1. Why is the 5μm–14μm wavelength range significant for this test?

This range corresponds to the "far-infrared" spectrum often referred to as the "light of life." Textiles that emit or reflect energy in this specific band are believed to interact most effectively with human skin for thermal and therapeutic benefits.

2. Can I adjust the distance between the sample and the radiation source?

The standard distance is fixed at 500mm to comply with GB/T 30127 and T/CAS 115.5-2021:Health Care Textiles — Part 5: Far Infrared. While some research applications may require adjustment, keeping this distance constant is essential for comparing results across different materials according to the standard.

3. What is the difference between Far-Infrared Temperature Rise and Far-Infrared Emissivity?

Temperature rise measures how much the fabric heats up when exposed to an external infrared source, whereas emissivity (tested via a different module/standard) measures the fabric's ability to emit its own infrared energy. Both are key to a full far-infrared evaluation.

4. Why is a 30-second test duration standard?

The 30-second window is optimized to capture the initial, rapid thermal absorption phase of the textile. This provides a clear "temperature rise" value ($\Delta T$) before the sample reaches thermal equilibrium with its surroundings.

5. Does the thickness of the sample affect the result?

Yes. Thicker samples or those with high loft (like fleece) may show different temperature rise characteristics compared to thin, flat weaves. This is why using the correct fixture (disk vs. frame) and ensuring center alignment is vital for accuracy.
