Textile Thermal Resistance Tester

Standards:

ISO 11092

ASTM D1518

ASTM F1868

GB/T 11048

Scope of Application:

Research and Development: To evaluate the thermal performance of new fibers, yarns, fabric constructions, and multilayer systems.

Quality Control: To ensure manufactured textile materials meet specified thermal resistance requirements consistently.

Product Performance Evaluation: To compare the thermal insulation of different textile products or assess the impact of aging, washing, or other factors on thermal performance.

Compliance Testing: To provide data required for product labeling and certification according to relevant thermal comfort or protective clothing standards.

Product Advantages:

The Textile Thermal Resistance Tester offers several advantages for evaluating the thermal insulation of textiles:

Measures Fundamental Property: Directly quantifies thermal resistance, a key indicator of a textile's insulating capability and contribution to thermal comfort.

Simulates Heat Transfer: Replicates the heat exchange processes (conduction, convection, radiation) that occur in real-world clothing use.

Provides Quantitative Data: Yields objective and reproducible numerical values for thermal resistance.

Product Features:

A constant-temperature heat source (hot plate) with precise temperature control to simulate skin temperature.

A guarding system around the hot plate to minimize lateral heat loss and ensure one-dimensional heat flow through the test specimen.

A cooling plate or controlled environment chamber to simulate the external temperature.

A mechanism for clamping the textile sample flatly between the heat source and the cooling plate or within the controlled environment.

High-precision temperature sensors embedded in the hot plate, cooling plate, and/or environmental chamber to monitor temperatures accurately.
