The weather is getting colder, and the thermal products of major shopping malls in Changchun have ushered in the first wave of buying craze this winter, among which the thermal underwear market is the most lively. However, many consumers are afraid to "sell" after shopping for a long time: there are too many brands with uneven quality, and new terms such as "bamboo fiber", "infrared ray" and "magnetic levitation heating" are written on the outer packaging. How does this work? Is it really as amazing as the manufacturer said? How can I buy thermal underwear with quality assurance?

After visiting the market, the reporter found that many thermal underwear are made of "high technology" such as fiber, bamboo charcoal, infrared ray and magnetic levitation, which can not only inhibit bacteria, sterilize and deodorize, but also claim to have magical effects such as moisturizing, slimming and temperature regulation, and the prices of such thermal underwear are also "uneven", ranging from 30 to 40 yuan cheap to 700 to 800 yuan expensive, or even thousands of yuan.

In a large shopping mall on Chongqing Road in Changchun, the reporter asked the salesperson with a thermal underwear marked "Selam". She told reporters that this is a new material, and it is better to keep warm in thermal underwear. She doesn't know the details. In order to prove that this kind of thermal underwear with a price of more than 400 yuan is hot, the salesperson also showed the reporter the sales record of nearly three days. "We sold 1 1 set in three days, which is the best in our family."

However, many citizens who came to buy thermal underwear said that the publicity of thermal underwear is indeed varied, and it is difficult for consumers to tell how real the magical thermal effect is. Ms. Wang, who bought a traditional cotton thermal underwear, told the reporter: "There are too many kinds of thermal underwear now, and some new terms are not even explained by the sales staff. Who knows if there will be side effects? To be on the safe side, it is better to choose pure cotton. "

The reporter then interviewed the provincial fiber inspection office by telephone. A staff member said that there will be a "noun war" in the underwear market every year. Manufacturers usually add some chemical components to the original polyester and acrylic fibers to change the molecular structure and give this acrylic fiber a new name. Regarding new terms such as bamboo charcoal, Seilam and modal, the staff said that these are additives, which have a more or less warm-keeping effect when added to underwear. However, she admits that the proportion of these ingredients in underwear is not very high. Compared with the expensive price, the cost performance ratio is not very high, and the whole thermal underwear market is generally exaggerated. Thermal underwear generally keeps warm in three ways. First, improve textile materials and isolate air; The second is to add film to keep warm; The third is to use new technology to add special materials to fibers. "However, in any way, it can only increase the warmth effect of 2℃ to 3℃ at most. Moreover, different people have different physical conditions and feel different when wearing clothes. "

So what should customers look at when choosing thermal underwear? The staff said that the most important thing for customers to buy thermal underwear is the warmth retention rate.

In the textile industry standard of knitted thermal underwear, the thermal rate has become an important standard to judge the quality of thermal underwear. However, the reporter found that few manufacturers label the detailed standards of thermal underwear and only use "fuzzy concepts" to promote sales, and few consumers know the hard indicators of thermal underwear. "The underwear market in the market is mixed, and many ordinary underwear are sold under the banner of thermal underwear. According to relevant standards, underwear can only be called thermal underwear if its thermal insulation rate is above 30%. When customers buy thermal underwear, it is necessary to see whether there is thermal insulation rate data on the clothes. If not, they should ask for a test report. " She also said that air permeability and moisture permeability are also indicators to measure whether underwear is warm. In a word, all textiles labeled as "thermal underwear" must meet the requirements of relevant standards in terms of warmth retention, air permeability and moisture permeability.

Some consumers feel "warm" at the same time, but they caught a cold because they wore thermal underwear. Dr. Li from the Dermatology Department of Changchun Central Hospital reminded us to pay attention to wearing thermal underwear. People who get angry heavily and easily should not wear thermal underwear. There are three main points to pay attention to: it is easy to catch a cold after wearing thermal underwear and sweating in the morning; Six types of people, such as eczema and dermatitis, should not wear thermal underwear; In addition, choosing thermal underwear is not a gimmick, but a health effect. When choosing thermal underwear, the fabric should be soft and comfortable, light in weight, elastic and warm.
