Textile moisture absorption and heat generation performance tester
The Textile Moisture Absorption and Heat Generation Performance Tester is a laboratory instrument designed to evaluate the thermal response of textiles when absorbing moisture. By simulating real-use humidity and airflow conditions, it 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 Scenarios
(1) Functional thermal underwear: evaluating moisture-induced heat generation and thermal comfort
(2) Sportswear and outdoor performance fabrics: testing fibers, yarns, and finished garments for thermal response under sweat or humidity
(3) Fiber and yarn development: assessing hygroscopic-exothermic treatments on raw fibers and spun yarns
(4) Fabrics with moisture-activated heat generation: testing treated fabrics for winter clothing, jackets, and thermal layers
(5) Winter apparel and insulation materials: measuring thermal comfort of coats, down jackets, quilted garments, and ski wear
(6) Bedding and home textiles: evaluating quilts, blankets, mattress toppers, pillow fillings, and mattress fabrics
(7) Medical textiles: testing hospital gowns, patient bedding, and temperature-regulating medical fabrics
(8) Smart textiles and temperature-adaptive fabrics: assessing heat generation for wearable electronics, adaptive sportswear, and intelligent fabrics
(9) Research and teaching: providing reliable data for textile engineering labs, R&D of functional fabrics, and academic experiments
(10) Quality control: manufacturers and inspection institutes use it to ensure consistent thermal performance of moisture-absorbing and heat-generating textiles
