Hygroscopic heating property tester for textiles
Category：Other
Introduction
The Hygroscopic Heating Property Tester is a specialized laboratory instrument designed to evaluate the moisture-wicking and heat-generating performance of textiles. When moisture is absorbed by high-performance fibers, an exothermic reaction occurs. This tester measures the temperature rise generated during moisture absorption, providing accurate data for product development, quality control, and performance verification of functional fabrics.
It is widely used for testing fibers, yarns, woven fabrics, knitted fabrics, sportswear, functional underwear, outdoor apparel, and moisture-responsive textile materials.
Application Fields
Functional moisture-wicking fabrics
Heat-generating underwear and sportswear
Outdoor performance apparel
Chemical fiber materials and research samples
R&D laboratories of textile mills and apparel brands
Third-party textile testing institutes
Applicable Standards
GB/T 29866–2013
Specifies methods for evaluating textile moisture-absorption and heat-generation performance. Applicable to various fibers, yarns, fabrics, and garments, measuring heat-generation after moisture uptake.

FAQ
1. What types of textiles can be tested with this instrument?
It can evaluate fibers, yarns, woven fabrics, knitted fabrics, sportswear, thermal underwear, and any material designed for moisture absorption and heat generation.
2. How does the tester measure heat-generating performance?
The tester introduces a controlled amount of moisture to the specimen and measures the resulting temperature rise using high-precision sensors, following GB/T and FZ/T standards.
3. Why are humidity and airflow control important?
Moisture absorption and heat generation are influenced by environmental factors. Controlled humidity and airflow ensure accurate, repeatable, and standardized test results.
4. Can multiple samples be tested simultaneously?
Yes. The multi-channel detection system (e.g., 4 channels) allows several specimens to be tested at the same time, improving laboratory efficiency.
5. Which industries commonly use this equipment?
It is used by textile manufacturers, apparel brands, sportswear R&D teams, quality inspection agencies, and research institutes focusing on functional performance fabrics.
