The Health Care Function Of Thermal Underwear Is Exaggerated &Nbsp, And Health Needs To Be Grasped By Oneself.

　　 Turn on the TV and turn on the newspaper. The advertisement of thermal underwear is really dazzling for consumers. Over here, it's super warm and superconducting. It's antibacterial, environmental friendly, sterilizing, and radiating far infrared. Even the latest high-tech nanotechnology has been sold as a thermal underwear by manufacturers. Thermal underwear is almost a medical device.

Faced with such crazy advertising bombing, many Consumer Doubtful: warm underwear publicity Health care function Is it really effective?

The health function is not clear.

Wang Baojun, director of the national cotton textile product quality supervision and testing center, said: "thermal underwear advertising is too much. In fact, the warmth retention function of thermal underwear is only the same as a thin woolen sweater. Some manufacturers claim that their products are worth two or three woolen sweaters and can resist -48 chill. This is because when the outdoor thermal insulation rate is tested, the plastic underwear inside the thermal underwear can block the movement of the air and prevent the loss of hot air, so it will be more warm than ordinary thin wool. But who will wear underwear as a coat to wear out? "

For some thermal underwear manufacturers propaganda superconducting wet, director Wang Baojun thinks, this is self contradictory, warm underwear is warm, very important point is that its permeability is relatively poor, blocking the convection of the air, but in this way, moisture is also covered in the inside, and talk about superconducting wet?

Yes Thermal Underwear Zhao Yufeng, Professor of Beijing Institute of labor protection, expressed doubts about the far infrared ceramic fiber. He said that ceramic fibers can only be stimulated at a temperature of 40 to 50 degrees Celsius and a large number of far-infrared rays can be stimulated, and the temperature of the human body can not be as high as that. Therefore, ceramic fibers can not greatly improve the thermal insulation properties of fabrics at room temperature, let alone the health care function of the human body.

Experts believe that the antimicrobial activity of manufacturers is also doubtful. If the antibacterial agent can really blend with underwear, then the antibacterial agent will change the molecular structure, and not the antibacterial agent. If there is no integration, then the antibacterial agent is only attached to the clothes and will be washed away once washed, and the antibacterial effect will not last.

Many thermal underwear manufacturers have been playing the role of nanomaterials in order to cater to people's desire for new technology. A thermal underwear claims that "the latest nanotechnology in 2000 can continuously release microwaves and play a health role in the human body". But they do not know that they have made a common sense mistake. Experts say that nanomaterials will not release health care microwaves, and nanotechnology applications are just beginning. Commercial propaganda is mostly commercial speculation.

Health needs to be grasped by itself.

According to the relevant departments, there are no relevant national standards and industry standards for thermal underwear. The testing method of thermal underwear's thermal insulation is only the "experimental method of thermal insulation performance of textiles" formulated by the state in 1989, and this standard is mainly for knitted underwear. By this standard, the present thermal underwear is obviously outdated and can not reflect the actual situation of the thermal underwear market at present. Therefore, in order to further regulate the thermal underwear market, it is imperative to introduce the quality standards and testing methods of thermal underwear.

Due to the lack of relevant laws and regulations, some enterprises have mixed fish in troubled waters, resulting in many good quality of thermal underwear. Many people have reflected that some manufacturers simply sell ordinary underwear and double cotton underwear with thermal underwear for profiteering. The State Bureau of technical supervision conducted a quality sampling survey of 30 products produced by 30 enterprises in Shanghai. The most prominent problem is that the thermal insulation rate of thermal underwear can not reach the level of product introduction. Many companies say their thermal underwear is equivalent to two or three sweaters. The test showed that the lowest retention rate of the 30 products was 48.4%, the highest being 61.94%, while the warmth retention rate of a sweater was about 50%.

The Chinese Consumers Association has detected 40 brands of thermal underwear sold on the market, and will announce the results by the end of November. It is believed that the difference between advertising promise and actual quality is clear at that time.

　　 In the face of overwhelming underwear, consumers should use a common heart to look at the publicity of manufacturers. Publicity is just for promotion. In fact, thermal underwear is far from magical. Keeping warm is not equal to health care. It should be more calm and rational.
