Where does thermal underwear come from? Heating underwear is also a kind of single product that we often see in our lives, and it is also a kind of clothes that many people like. Thermal underwear also has many warm-keeping functions for us, and it is very effective to resist the cold. Let's share where the hot underwear comes from.
Where does thermal underwear come from? 1 The main raw material of heating underwear is moisture-absorbing and heat-gathering fiber.
Many businesses are selling thermal underwear. The main components of the trademark are polyester fiber and acrylic fiber, in addition, it also includes a small amount of viscose fiber and spandex. The reporter found that many heating underwear claim that the fiber itself can absorb the water vapor evaporated by the body and convert it into heat energy, and the material itself will heat up.
"The concept of heating underwear originated in Japan. The original heating underwear was improved chemical fiber materials, mainly chemical fiber for daily use. Because the fiber has good moisture absorption and heating function. In fact, there are many ways of heating, including heating after moisture absorption and heating with electric energy to convert solar energy into heat energy. At present, the common heating underwear on the market basically achieves the effect of keeping warm through the principle of moisture absorption and heating. " In fact, all fibers have heating effect, but the heating degree and calorific value of different fibers are different. From the heating effect, natural materials, such as wool and viscose fiber, generally absorb more water, and their calorific value is greater than that of ordinary fiber. It is found that the calorific value of wool reaches 26.9 calories, which is more suitable for heating underwear materials.
Heating fibers were first used by climbers.
The raw material of heating underwear is a special fiber material, which is expensive. Generally, heating underwear is made of a small amount of heating fibers and other fibers. Most of them contain viscose fiber, modal fiber, bamboo charcoal polyester fiber or recycled fiber. This fiber material was first used for mountaineers, and later extended to the general consumption field, mainly used for making underwear. For example, "Selam" is actually adding superfine ceramics to chemical fiber acrylic fiber to make it have a heating effect. "Modal fiber" is a kind of material with high moisture regain, which can be converted into heat and released after absorbing water.
"With regard to heating underwear materials, in recent years, foreign countries have developed new fibers that can heat themselves and become materials for thermal underwear. The main method of making warm and heating fiber is to add special chemical components to the fiber to make it react chemically under specific conditions to generate heat. For example: Thermotron fiber-solar thermal storage and insulation fiber, Outlast air conditioning fiber-phase change thermal storage fiber, Eks moisture absorption and heating fiber, Textcare nano bamboo charcoal fiber and Ceramino infrared thermal storage and insulation fiber. At present, domestic underwear manufacturers mainly use moisture-absorbing and heating fibers as raw materials, and develop knitted fabrics through different proportions and processes to change the heavy and bloated appearance of traditional warm fabrics and make them light, soft and warm.

How to distinguish true velvet from false velvet
Derong underwear is a kind of thermal underwear that people like best nowadays, because it is light and easy to wear. Because of this, fakes are rampant in the market, so you must carefully identify them when buying, as follows:
1, velvet fabric feels very delicate and skin-friendly!
2. Delong contains a certain proportion of acrylic fiber, so the wear resistance is particularly good!
3. Delong fabrics generally contain a certain proportion of spandex, which is about 5%, so Delong fabrics have good elasticity and are very suitable for self-cultivation!
4. Delong is generally reactive printing and dyeing, and the fabric will not fade after repeated washing! This is very good for the bottom of the body!

Where does thermal underwear come from? 3 uniqlo's heated underwear HEATTECH has been on the market for three or four years. When I first heard about HEATTECH, I was still working in the media. Uniqlo specially gave me some hot underwear to experience first. And as a media, I also carefully studied the press release of HEATTECH, which made some professional explanations on the principle of fever.
I won't repeat the heating principle of HEATTECH. There are many great gods on the internet who have made professional evaluations. After all, we ordinary people are not experts in textile fabrics. In fact, it is hard to say whether it is good or not from a scientific point of view. But because I have been a media for a long time, I also know that it is very important for many brands to find some marketing selling points for new products.
Therefore, when I was wearing HEATTECH, I didn't expect this underwear to really achieve the effect of keeping warm by wearing a sweater, but it is really comfortable to wear HEATTECH underwear, which fits well, is not easy to deform and stretch, has good elasticity and is very thin. These characteristics are not available in many pure cotton underwear.
However, HEATTECH also has some shortcomings, that is, it is easy to pilling after wearing for a long time, and people who are picky about the feel may wear it in autumn and winter. Especially some parts that are easy to wear, such as elbows and knees, are easy to get thinner and thinner.
For many girls, it is very good to wear HEATTECH as a bottoming shirt. For boys, it is also very suitable to wear under shirts, but the degree of warmth depends entirely on personal feelings and weather conditions. If some people are afraid of cold, then I suggest you wear three clothes to keep warm. Although HEATTECH's so-called "self-heating" has certain scientific truth, it is not to warm the baby after all, and it is impossible to give off high heat when put on.
Merchant marketing always has a selling point, and the state also has advertising laws on advertising. As a big brand with high sales volume, Uniqlo certainly does not dare to touch the legal red line easily, but it will definitely think of some tricks in some marketing strategies. After all, HEATTECH didn't say how hot it would be, so you don't have to wear sweaters and down jackets. They just used some objective scientific principles as marketing selling points. Don't be too serious. Wearing comfortable clothes is the most important thing. Keeping warm depends on big cotton-padded jacket and down jacket.
