Therefore, even if it is a real heating underwear, its temperature rise can not be very high, and generally it can actively raise the temperature by 2℃ to 4℃. Beware of counterfeiting when buying thermal underwear. At the same time, it should be noted that even the real heating underwear has limited temperature and cannot be used to replace cotton-padded clothes.
The heating principle of 3-second extremely hot thermal underwear: Using regenerated heating fiber cotton to strengthen the tension of fiber shell and narrow the barrier can achieve the effect of constant temperature and warmth in a lighter state than raw materials. Women are heavy in moisture, and the heating fiber used is to convert moisture into heat energy.
Play the role of heating constant temperature; The temperature of imported heating fiber is 3-3.5 degrees higher than that of ordinary heating fiber. High-grade ultra-thin fabric with high elasticity.
Extended data:
Heating principle of heating underwear;
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. Therefore, the real heating underwear temperature rise is not so high, generally can take the initiative to raise the temperature by 2℃ to 4℃.
Features of thermal underwear:
1, fever: the effect of fever is achieved by absorbing the moisture produced by human skin breathing.
2. Moisture retention: the middle part of the fiber contains static air, which produces good heat insulation effect, which not only reduces the weight of the fabric itself, but also has excellent heat insulation for static air.
3. Humidity regulation: Using the capillary phenomenon produced by tiny grooves on the fiber surface and special spinning technology, excess water can be quickly absorbed and distributed through wicking, diffusion and transmission, thus keeping the body dry.
4. Softness: Imitate the natural fibers in the natural ecology, endow the fiber surface with numerous breathable micropores, and achieve the softness and comfort of natural fibers.
5. Good pilling resistance: By using special spinning technology, the pilling resistance of similar yarns is greatly improved.
