Does The Self Heating Underwear Really Keep Warm?

With the snowfall of last weekend, the temperature in Binzhou has dropped sharply, and various shopping malls have launched various kinds.

Many new thermal underwear are crowned with "new materials" and "hi tech" labels. The price ranges from several hundred yuan to thousands of yuan, and the public is also confused.

Bamboo charcoal material, regenerated fiber, far-infrared radiation fiber...

Are these new thermal materials really warm? Are they worth the money? Most people do not know.

One of them is "hi tech" thermal underwear, which uses "Salam" material and uses far-infrared principle to keep it warm.

New materials for thermal underwear

The public has not heard or seen.

On the 6 day, the reporter came to a large shopping mall on the four road of the Yellow River Bohai seven.

In the two floor underwear counters, many businesses have placed thermal underwear in the prominent position of the shelves. Many people are choosing.

The price of thermal underwear ranges from several hundred yuan to more than 1000 yuan.

Less expensive underwear, most of which is polyester, and some of which are new materials that have not been heard.

For example, a set of underwear "salad" on the label is only 599 yuan, which is marked by "using advanced spray technology to twist the far-infrared radiation ceramics into acrylic fibers".

"This warm underwear is priced at over 1000 yuan, which says" salad "is made of a new material and uses far infrared radiation fibers, but we don't understand it at all.

"I feel warm underwear, warm is OK, what material is not important," Zhang said.

But now these high-tech products really make me do not know how to choose.

On a separate counter not far away, the reporter saw that the shelves were full of thermal underwear.

It is also not thick. The sign on it is written on the three words of "heating clothes". The following is an introduction: automatic heating, the highest temperature can be increased by 3.4 degrees Celsius.

"Can such a thin underwear keep warm?" the salesperson said that the thermal underwear was made up of high-tech heating fibers, which is a revolutionary fiber with moisture absorption and heating function.

When the fiber absorbs moisture from the body, it produces an "adsorption heat" to achieve the effect of warming up.

This kind of thermal underwear is very thin, but its thermal effect is much better than that of ordinary thermal underwear.

Now we are pursuing fashion. Unlike the originally thought that the thicker the clothes are, the more warm they are. These new materials can get warmth by using far-infrared rays.

Careful selection of new materials

It does not apply to everyone.

This kind of "hi tech" and "new material" thermal underwear is often on the top of thousands of yuan, which has made many consumers "deterred".

As far as welcome is concerned, it is better for ordinary thermal underwear.

Whether these new materials are really able to keep warm, an industry insider said that the principle of using infrared rays to warm oneself in underwear for warm underwear is the same as those containing the substance of tourmaline.

"But this is a medical physiotherapy, and a healthy citizen does not need it. If used, it may be counterproductive."

"Now some of the thin underwear on the market can achieve a certain degree of warmth, but the life expectancy is generally in a year or so, and the effect will drop if the time is longer or the water is washed more."

According to the industry, ultra-thin thermal underwear usually has a layer of membrane, which is more expensive, but the shelf life is one year. After a year, the membrane loses its efficacy and needs to be replaced.

Most of the thermal underwear with this membrane is over 1000 yuan, while the cheaper thermal underwear sold on the market is filled with ultra-thin plastic film, though it has certain thermal effect, but it is airtight.

About the price, the cost of thermal underwear is determined according to the market, the price of professional materials is different, and the price is different.

"Some

The price is about four hundred or five hundred, and the total agency is about 150 yuan, and the cost is eighty or ninety yuan.
