Thermal Underwear, Technology Card, Quality Supervision: Same As Ordinary Thermal Underwear.

"It's getting cold recently, and I'm going to buy a warm underwear for the elderly at home. When I look at the counter in the supermarket, what kind of warm velvet, pearl velvet is written on the box, I am dazzled by it. What is this warm velvet in the end? I haven't heard of it before. Is there any warmth retention effect?" in November 22nd, Ms. Jiang, who lives in Licun, told reporters.

On the morning of November 23rd, the reporter came to a large supermarket located in Ningxia Road, and the thermal underwear shop was crowded with many shoppers. Reporters on the shelf saw a Suzhou Yalu company priced at 108 yuan. Keep warm Underwear, a dark red box, says "gold warm linen thermal underwear". On a discount shelf not far away, there is also a 78 yuan suit of thermal underwear. The blue box shows "warm velvet".

How much do people know about this "warm velvet" and "golden warm velvet"? "I don't know, is it a special material? I don't know much about this." Several citizens said. The supermarket's shopping guide told reporters: " Packing box Warm velvet written on it. Gold warm pile This is a new material that is more warm than previous thermal underwear. "

Is it true that, as shopping mall's shopping guide has said, "warm velvet" and "golden warm velvet" are all new materials. With questions, in the afternoon of November 23rd, the reporter came to the Textile Inspection Institute of Qingdao Quality Supervision Bureau. "In fact, these are the publicity gimmicks of businesses." warm velvet "," golden warm velvet "and" pearl velvet "are a kind of" gimmick "fiber. They actually do not exist. The underwear made of these names is almost the same as those of ordinary thermal underwear. Jin An, director of the technical department of the Institute of fiber inspection, told reporters: "the ingredients and raw materials for producing warm velvet are polyester polyester and acrylic fiber, and pearl velvet is made of polyester polyester or viscose fiber plus some pearl powder."

"All raw materials used in textiles can be divided into chemical fibers and natural fibers. Natural fiber is known as cotton wool and linen, which is known to ordinary people. It is very difficult to counterfeit natural fibers. Most people do not know much about chemical fibers, so they tend to become businessmen 'hype objects," he said. "According to the national standard GB/T4146.1-2009, the first part of textile chemical fibers: the name is". There are 28 kinds of chemical fibers used in textiles, commonly used acrylic, polyester, spandex, modal fiber and so on. As long as the names marked on the labels of the business exceed those 28 kinds, they are abusive names.

It is understood that the price of different fibers used for making garments is different. Some illegal manufacturers use cheap fibers to pretend to be high priced fibers in order to earn black money. "The price of a ton of acrylic fiber is twenty thousand or thirty thousand, and the price of the wool market is much higher than that of acrylic fiber. Because of its good thermal insulation and cheap, it is often used as a fake wool by merchants. Viscose fiber is very easy to be a target of counterfeiting because its appearance and handle are not very different from cotton." Relevant staff of the inspection office told reporters.

According to the staff, the chemical fibers used for textiles are not of high quality. Only with different prices, different fibers have different uses because of their own properties. Polyester is often used as summer clothing. Acrylic fiber is used for making winter clothing because of its good thermal insulation, while nylon is used for outdoor mountaineering garments.

If there is a problem in the purchase of thermal underwear, what should the common people do? "Consumers must first save the tag and invoice to safeguard their rights, because the tag shows the ingredients and contents of the raw material used in the thermal underwear, so as to compare the results obtained by the assimilation test," the chief of the section of the silk inspection division proposed to the general public: "consumers first buy qualified thermal underwear first to the regular shopping malls and supermarkets, not to attract the fancy gimmicks on their packaging, to distinguish the real ingredients and contents of the clothes, and to see the logo of the products."
