Thermal Underwear Sells High Tech Prices.

According to the voice of China news evening peak, as the days get colder and colder, many people choose.

To resist the cold.

And many brands have launched warm underwear as a new concept in products, the most expensive and even sold to thousands of dollars.

Are these so-called high-tech underwear made of hype or propaganda, or are they really magical?

Reporters in the mall underwear area to see, many brands have launched a heated underwear, as a product of the new concept.

Reporters found that when choosing underwear, traditional

It is still the first choice for most consumers, but the salesperson will enthusiastically recommend the underwear with "fever" function to the customers.

According to the salesperson, these new "underwear" contain all kinds of new materials that are said to be "hot".

Reporters noted that seventy or eighty yuan can buy a set of cotton underwear, after adding new material, the price of a set of underwear reached more than 300 yuan, the highest even reached 1000 yuan.

The salesperson told reporters that although the price of "hot underwear" is much more expensive than that of traditional cotton underwear, many customers are still willing to spend extra money for its "fever" function.

Dong Jinshi, an environmental chemistry expert who has long paid attention to underwear materials, said that most of the so-called "hot underwear" contained viscose fibers.

Bamboo charcoal polyester fibers are chemical fibers or regenerated fibers, mostly from by-products in petroleum processing. These materials have long been discovered and are not new inventions.

Dong Jinshi: These are not new materials. In fact, they used to be very early, such as polyester, modal and bamboo charcoal fibers will be used in many clothes in our daily life, including our socks, scarves, sheets and so on. These natural ingredients, such as modal and bamboo charcoal fibers, are natural fibers, such as some polyester fibers, which are all synthetic, and are not new materials.

Reporters found that although many brands have so-called "hot underwear", but the names of heating fibers and fabrics are not the same, but for most of the underwear's heating principles, most of the salespeople are not sure about themselves.

In this regard, Dong Jinshi told reporters, for example, we are very familiar with the "modal fiber", is a large moisture regain material, can be absorbed after the water into heat release.

For example, "salad", in fact, added ultrafine particles of ceramic in the chemical fiber acrylic fiber, so that it has the effect of heating. This technology has been used in many new fibers.

Dong Jinshi: these materials are relatively large in density, and the heat in our bodies is not easy to emit. Even some polyester fibers have certain reflectivity, that is, they can reflect the heat of our bodies.

It can feel that the body is warmer, some of the density is relatively large, such as bamboo charcoal fiber density is relatively large, the wind outside is not easy to enter, so it plays a role of increasing temperature.

Dong Jinshi said that in 2010, the relevant departments have issued and implemented the industry standard of "moisture absorption and heating knitted underwear", which stipulates that the real "hot underwear" needs to put up the Yellow underwear "hot underwear logo" on the box, the name of the heating fiber, the heating effect and the proportion of adding should be clearly marked.

Dong Jinshi also reminded consumers to pay attention to the logo of the hot underwear and carefully choose the hot underwear.

Dong Jinshi: we must see clearly the logo and logo, and have a national logo to prove that you have a warming function.

If there are no such signs, it is only the business publicity that it has warming, insulation, warmth and so on these instructions, try not to purchase, in order to prevent deceived.

It does not play the role of warmth, it may also cause some harm to our body.
