High Tech Underwear, Dry Skin And Easy To Sweat People Wear Less.

< p > compared with previous years, this year's thermal underwear has also started to upgrade with the so-called "hot underwear".

Is it true that the hot underwear is hot as propaganda? What is its raw material? Will it cause harm to the skin? < /p >

< p > < strong > heating underwear is known as high tech < /strong > < /p >.

< p > on Taobao, you will see that many stores are selling "a href=" //www.sjfzxm.com/news/index_h.asp "fever underwear" /a, "heating technology underwear", for example, there is a selling underwear, called top salad fiber underwear.

This kind of underwear is made of salad fiber, and the advanced technology of spraying is used to twist the far-infrared radiation ceramics into acrylic fibers, and the interaction between far-infrared rays and materials will completely regenerate the heat generated by the body itself through underwear, so as to achieve the effect of heating and keeping warm.

This kind of underwear sells at a price of around 140 yuan. It sells very well, and has sold 347 pieces in the last week.

< p > in addition to colored Rahm's underwear with hot fiber, there are also some hot underwear with milk protein fiber, viscose fiber, modal fiber, bamboo charcoal polyester fiber and regenerated cellulose fiber.

In shopping malls, many businesses are also selling other materials of thermal underwear, a closer look at underwear labels, their main components are polyester fiber and acrylic fiber, in addition, but also a small amount of viscose and spandex.

< /p >

< p > and in many promotional advertisements for hot underwear sales, many underwear claims that its own heating fiber absorbs the vapour evaporated by the body and converts it into heat energy, which causes fever to warm the body.

< /p >

< p > < strong > the effect of heating underwear is not good. < /strong > < /p >

< p > it is understood that fabrics like "a href=" //www.sjfzxm.com/news/index_s.asp "salad" /a "are actually chemical fibers.

Salam is a new term. In fact, it adds ultrafine ceramic to the chemical fiber acrylic fiber, which gives it a far infrared heating effect. This process is applied to many new fibers, while another common heating fiber, modal fiber, is a material with high moisture regain, which can be pformed into heat released after absorbing water.

< /p >

< p > experts say that more and more companies are trying to add more scientific and technological ingredients to products. But the market is full of "gimmick" and "X" velvet in the proportion of thermal underwear is generally low, the effect of underwear on heat and warmth can play a very small role, and even the real hot underwear, the temperature is also limited.

< /p >

< p > < strong > remind < /strong > < /p >.

< p > < strong > dry skin and sweating people should wear less /strong < /p >

< p > at present, "Salam" and other new kinds of chemical fiber material underwear are quite popular. Many new materials, such as fresh and warm underwear, are made of chemical fibers or man-made fibers, which can keep warm by blocking the skin and exchanging heat with the outside world. This kind of thermal underwear has poor air permeability, and chemical fibers are prone to static electricity, so that the moisture content of the skin decreases, becomes dry and dandruff increases.

< a href= "//www.sjfzxm.com/news/index_f.asp" > dry skin > /a > skin loss and skin diseases or allergic skin diseases such as dermatitis and psoriasis. It is easy to get sick. In addition, for the sake of beauty, most of the thermal underwear are designed with close fitting design. Among them, there are not cheap products although they have heating fibers, but they are made of composite sandwich materials to prevent heat from coming out, which makes people sweat easily.

Sweating people usually do not wear such hot underwear. At the same time, sweat can also release a little amount of underwear materials, especially pigments. If it is allergy, it will cause skin itching.

< /p >

< p > experts remind consumers that they can look at their underwear labels. Many underwear labels are made of cotton underwear. Actually, they occupy a higher proportion of polyester fibers.

It uses polyester as the main raw material, adding certain functional masterbatch, actually it is also a kind of polyester fiber. Its main function is small hygroscopicity and good light fastness, but its thermal performance is not as good as that of all cotton underwear.

< /p >

< p > experts suggest that it is better to wear underwear made of natural materials at ordinary times, such as cotton and wool underwear. Some regenerated cellulose fibers, such as "modal", are good underwear materials because of their good moisture absorption.

< /p >

< p > < strong > buying underwear for heating should be based on "yellow bottom black character" sign < /strong > < /p >.

< p > the heating fiber used in the heating underwear has the effect of moisture absorption and automatic heating, while the thermal underwear is achieved by reducing the air permeability and reducing the heat loss of the human body, so as to achieve the effect of keeping warm.

< /p >

< p > December 2010, China has implemented the industry standard of moisture absorption and heating underwear, and has also tested special standards for the standard of heating underwear.

According to the industry standard, judging whether it accords with the standard of heating underwear, there are two main dimensions: first, the minimum peak temperature should be greater than 3 degrees Celsius; in addition, considering the heat dissipation and other factors, the average temperature increase in 30 minutes is greater than 2 degrees Celsius, which is the lowest threshold.

< /p >

< p > some enterprises will confuse the concept of ordinary thermal underwear and "a href=" //www.sjfzxm.com/news/index_f.asp "heating underwear > /a", and sell ordinary thermal underwear as a hot underwear, while some businesses exaggerate the warm effect of heating underwear in order to make money.

Therefore, consumers have better buy formal underwear at regular shopping malls.

At the same time, consumers should see clearly whether the name of the heating fiber is marked on the packaging box, the heating effect and the Yellow bottom black word "heating underwear" logo are added.

< p > < strong > correlation < /strong > < /p >.

< p > < strong > the types of common hot underwear are < /strong > < /p >.

< p > moisture absorption and fever < /p >

P > the most common type of underwear with hygroscopic fever is the "moder" fever fiber.

Its heating mechanism is that when the fiber absorbs moisture, the hydrophilic groups in the fiber molecules combine with the water molecules, and the kinetic energy of the water molecules decreases, and at the same time, the heat is released into heat.

Generally, the moisture absorption and heating properties have a great relationship with moisture regain. The moisture regain of the fibers is high, and the moisture absorption and heating performance are good.

For example, modal fiber, wool moisture absorption and heating effect is good; ordinary acrylic fiber, polyester fiber moisture absorption and heating effect is poor.

< p > solar energy storage < /p >

< p > absorbs solar energy by adding special substances in fiber to heat energy, and emits long wavelength far-infrared rays to warm the interior of clothing.

For example, before mentioned "< a href=" //www.sjfzxm.com/news/index_f.asp > Salam /a > "fever fiber".

< /p >

< p > phase change heat storage < /p >

< p > this kind of hot underwear is very rare, and the price is the most expensive among the three.

Its heating principle is to absorb, store and release heat in the form of latent heat by adding thermal sensitive phase change material in the fiber.

In the process of temperature change, solid liquid can be pformed into each other, so as to achieve the effect of heat absorption and heating.
