Consumption Trap In The Market Of Warm Underwear

Analysis of "keep warm"

Whether the warmth is related to the thermal conductivity of the material itself, the smaller the thermal conductivity, the better the warmth retention.

In fact, the thermal conductivity of most clothing fibers is not very different, but because of the difference in the structure of warm fabrics, the thermal insulation of stationary air is the best.

Thermal underwear is made of "hollow" chemical fiber material, which has large space structure and contains still air, so it has certain thermal effect.

Doubts caused by "card" and "element"

"Card" and "vegetarian" once became

The selling point, according to industry sources, is that they are not so mysterious as advertisements, but they are only the aliases of the manufacturers.

For example, "warming card" and "thermal card" are acrylic fibers. "Sevic" is polyester, "Lycra" and "magic card" are fibers that are elastic and not easy to be rolled up and rolled up. "Warm element", as the name suggests, is a warm element. This is its trade name. Its scientific name is super fine double acrylic fiber.

Antibacterial effect is discounted.

"Underwear with non-toxic harmless antibacterial agents, harmful to human pathogenic bacteria to kill."

Such advertisements also have moisture.

Experts point out that if antibacterial agents can be integrated with underwear, then the antibacterial agent will change the molecular structure, and it will not be an antibacterial agent.

If there is no integration, the antibacterial agent is only attached to the clothes, then it can be washed away, and the antibacterial effect will not last.

Cotton and elasticity are also a pair of contradictions.

Cotton is a kind of cotton without delamination.

Instead of elastic fibers, let alone elasticity.

Cotton and super elasticity cannot be owned at the same time.

Moreover, the thermal underwear thermal insulation layer is chemical fiber, if inside and outside

The two layer is all cotton. These two different properties are bonded together with the same adhesive, so it is difficult not to shell out.

In addition, even if the inside and outside two floors usually add chemical fiber ingredients, it is difficult to reach 100% pure cotton, because cotton is really a shrinking problem.

Far infrared rays keep warm and do not care.

Any substance can emit far infrared rays and keep warm.

Generally after infrared treatment, far infrared emissivity has been enhanced, resulting in far-infrared radiation will also increase, thereby playing a role in warming.

As far as the health function of far-infrared rays is concerned, experts believe that the ingredients of publicity are far greater than the actual effects.

The far-infrared rays emitted by thermal underwear are similar to the far-infrared rays emitted by the human body. They have certain auxiliary effects on diseases such as joints and frail and cold. Other therapeutic effects such as helping sleep are exaggerated.
