Textile moisture absorption and heat generation performance tester

The Textile Moisture Absorption and Heat Generation Performance Tester is a professional laboratory instrument designed to evaluate the thermal response of textiles when absorbing moisture. By simulating real-use humidity and airflow conditions, the tester measures temperature rise, heat-release characteristics, and thermal comfort performance of fabrics, fibers, yarns, and finished garments. It is widely used in the development and quality control of moisture-absorbing and heat-generating functional textiles, including thermal underwear, sportswear, outdoor apparel, bedding materials, and smart temperature-regulating fabrics.

Application

This instrument is suitable for measuring the moisture-absorption-induced heat generation of various textile materials. It is commonly used for:

Functional thermal underwear

Sports and outdoor performance fabrics

Fiber and yarn development evaluation

Fabrics with hygroscopic–exothermic treatments

Winter apparel and insulation materials

Bedding, mattress toppers, quilt fillings

Medical textiles requiring thermal response

Research and teaching in textile engineering

R&D of smart temperature-adaptive fabrics

It provides essential data for manufacturers, research institutes, inspection bodies, and textile laboratories requiring accurate moisture-induced thermal performance testing.

Maintenance

Clean the inner chamber regularly to ensure accurate humidity and temperature control.

Check and calibrate temperature and humidity sensors on a scheduled basis.

Inspect heating, humidifying, and refrigeration components for stable performance.

Replace worn seals to maintain airtightness and chamber stability.

Keep the instrument in a clean, dry environment to prevent corrosion or contamination.
