The instant cool feeling of the contact is that the skin contacts with the fabric with the temperature lower than the skin to cause the rapid loss of heat on the surface of the skin, the temperature drops instantly, and the cool feeling is formed after the heat is reflected to the brain through the nerve endings in the skin. The contact cooling coefficient is expressed by a unit time unit area heat flow rate Qmax, and the unit is J/(cm) 2 S). The test method comprises the following steps: under a predetermined test environment condition, a heat detection plate having a temperature higher than that of the sample is brought into contact with the sample, the change with time of the temperature of the heat detection plate is measured, and the contact cooling coefficient (Qmax) is calculated, whereby the cooling performance at the moment of contact of the sample can be characterized. The larger the Qmax value is, the stronger the skin feels cool; the smaller the value, the less cool the skin feels.
