Hot underwear will give off heat. Relevant experts remind the public to beware of counterfeiting when buying hot underwear. At the same time, it should be noted that even if it is really hot underwear, the increased temperature is limited and cannot be used instead of cotton-padded clothes.

The raw material of heating underwear is a special fiber material imported from Japan around 2000, which actively heats up by absorbing the moisture emitted by the human body. This fiber material was first used for mountaineers, and later extended to the general consumption field, mainly used for making underwear. The materials used in the heating underwear produced by domestic manufacturers are all imported from Japan.

Because this kind of fiber material is expensive, general heating underwear is made of a small amount of heating fiber mixed with other fibers. Yang Shibin, chairman of the China Knitting Industry Association, added that, therefore, it is impossible for real heating underwear to rise that high, and generally it can actively raise the temperature by 2℃ to 4℃.

Extended data

In order to effectively safeguard the legitimate rights and interests of consumers and maintain a fair and competitive market order, China Consumers Association and China Knitting Industry Association jointly issued the following consumer warnings:

Heating underwear is not thermal underwear. The heating fiber used in heating underwear has the function of absorbing moisture and actively heating, that is, the heat of heating underwear is actively generated by underwear, while thermal underwear achieves the effect of keeping warm by reducing air permeability and reducing the loss of human heat, which underwear does not produce.

Don't trust the oral introduction of the salesperson. When consumers buy hot-selling underwear, don't believe in advertisements and empty introductions from shopping guides, and be deceived on impulse.
