Is The "Technology Brand" Thermal Underwear High-Tech?

Recently, the reporter visited a number of shopping malls and underwear stores and learned that the sales of thermal underwear have soared recently due to the cold weather. This year, many brands of thermal underwear are playing technology cards to attract consumers.

The reporter saw in the underwear counter of a shopping mall near Taitung that various thermal underwear were placed in a prominent position, attracting many citizens to choose and buy. The reporter noticed at the scene that in order to attract customers, many brands hold up the "high-tech" signboard to attract the public's attention. Professional terms such as body slimming, bamboo charcoal, anti-bacterial, infrared heating warm card, golden velvet, warm velvet, milk protein fiber, Salam infrared, etc. dazzle people.

The reporter saw at the scene that many citizens are very interested in "high-tech". Miss Liu, a white-collar worker, is buying a slimming underwear. She told reporters that this underwear has the effect of beautifying the body. After wearing it, she can not only highlight her body but also achieve the goal of losing weight. Ms. Zhang, a citizen, wanted to buy a set of underwear for her parents. The salesperson of the thermal underwear counter warmly recommended to her a "thermal underwear that can promote blood circulation and enhance metabolism". After listening to the introduction, Ms. Zhang bought this expensive "high-tech" thermal underwear. Ms. Zhang told the reporter that her mother was always in poor health, and she was easy to catch cold when it cooled down in winter. Seeing the powerful effect of this thermal underwear, she decided to buy it for her mother.

The price of "technology" products doubled

Once upon a time, the role of thermal underwear has been upgraded from simple and pure warmth to various functions such as body building, promoting blood circulation, and enhancing metabolism. However, as long as the thermal underwear with the mark of "high-tech" is more expensive than ordinary thermal underwear, it will be twice or even several times more expensive.

The reporter saw in an underwear store in Taitung that the price of a set of ordinary underwear is about 100 yuan, and some high-grade thermal underwear with velvet is priced at 200~300 yuan, while products labeled "high-tech" are often hundreds of yuan or even thousands of yuan. The staff of the store explained that the high-tech and high price underwear is that ordinary thermal underwear is only for warmth, while high-tech thermal underwear is not only for warmth, but also for health care. Of course, the price is high. For example, a kind of underwear uses high-tech materials, which contains a mineral that can regulate the temperature of the human body. When the user's body is hot, it will absorb its own heat, and when it is cold, it will release, so that the user's body can keep constant temperature.

Citizens have different opinions on high-tech underwear. "I have never heard of it. It may be a lie. As long as it is warm, it is OK to keep warm underwear," said Ms. Li, a citizen. Mr. Zhang, a citizen, also said that he still believed in the old brand, the quality was reassuring, and the price was affordable; However, some young people believe that with the development of society and technology, high-tech underwear must be better than ordinary underwear.

High tech is mostly a promotional gimmick

There are a variety of "high-tech" thermal underwear on the market, but the fabric feels similar to ordinary thermal underwear, and its "technological content" makes many citizens have doubts.

Xu Dong, who has been engaged in underwear wholesale for many years, told reporters that the so-called "high-tech" thermal underwear currently sold on the market has been hyped about its efficacy, but in fact, it is mostly a sales gimmick of businesses. Like warm velvet and golden velvet, they are still chemical fibers. The ingredients and raw materials for making warm velvet are mostly polyester polyester and acrylic fiber, while pearl velvet is mostly made of polyester polyester or viscose fiber plus a little pearl powder. The so-called "beauty and slimming" effect of some warm underwear is actually to reduce the size of the original underwear and make it fit when wearing, rather than really lose weight, And there is no final conclusion on the health care function of some thermal underwear.

How should citizens choose thermal underwear? Xu Dong said that according to relevant national regulations, no matter what kind of thermal insulation materials are used, the outer packaging of finished products must be marked with "thermal insulation rate" and "thermal insulation rate per gram". For products with the nominal "thermal underwear", the thermal insulation rate shall not be less than 30%, that is, at least 30% of the heat energy shall be protected from loss. Consumers can judge the thermal function of underwear according to these two indicators. The higher the warmth retention rate, the warmer the wearer is wearing, and the higher the warmth retention rate per gram weight, which means that the less fiber materials are used in the fabric, the lighter the product weight, "light, warm and thin", and can reflect the relationship between the warmth retention performance of the thermal underwear and its own weight and thickness. In addition, at present, the underwear market is a mixture of good and bad. When buying thermal underwear, citizens should go to large and medium-sized malls with guaranteed reputation to buy famous brand products produced by well-known enterprises.
