Method and equipment for testing heat retention property of down garment

The invention discloses a method and equipment for testing heat retention property of a down garment. The complete testing method for the heat retention property of the down garment is obtained through partial and overall subjective feeling of a human body to the down garment and objective data acquisition of temperature changes of all parts. The down garment is redesigned with rank ordering of the sensitivity degrees of the different parts to the heat retention property as the reference, and finally the down garment which is extremely good in heat retention property and has forward-looking design creativity is obtained. By means of the method and equipment for testing heat retention property of the down garment, temperature changes of the different parts of the human body can be reflected truly, the method and equipment can be applicable to testing in various low-temperature or high-temperature environments, testing operation is simple, the measuring result is accurate, and measuring efficiency is high.
