Contact heating and cooling tester STD-F7
The sensation of coldness or warmth when skin touches a fabric is referred to as the "coldness and warmth feeling." The feeling of coldness or warmth will vary depending on the amount of heat transferred from the skin to the fabric. This device measures that feeling by evaluating the "qma" value (peak heat flux).
Test standard
JIS L 1927Textiles-Measurement method of cool touch feeling property
GB/T 35263-2017Textiles-Testing and evaluation for cool sensation at contact instant
CNS15687. L3272Method of test for the instantaneous cool sensation fabrics
The Thermo Labo can be used to evaluate such products as bedding material meant to offer a feeling of coldness in summer, and underwear material meant to offer contact warmth in winter.
Features
A design that mimics the sensation of actually touching an object
The load and contact area of the heat plate, which is brought into contact with the target sample, is designed to imitate the sensation of touching an object by hand, allowing for more realistic measurements of maximum heat transfer amounts.
Also measure thermal conductivity and heat retention properties (with optional accessories)
Thermal conductivity
With constant thermal conductivity measurement, the ease at which heat is transmitted from a heat plate with a constant temperature (30℃) through a sample to a heat plate with a separate constant temperature (20℃).
Heat retention properties (optional accessory)
The sample is set on a heat plate with a constant temperature (room temperature +10℃) and is left in contact with the air. A constant wind is then applied continuously to the sample surface. The amount of heat lost through the sample is then measured in order to calculate the heat retention rate (%). Measuring methods include a dry method that assumes direct contact is made with dry skin or clothing and a wet method that assumes contact is made with sweaty skin or clothing.
