Warm Underwear "High Tech" Consumers Need To Be Cautious About Buying.

"This kind of thermal underwear contains bamboo charcoal fiber and gold velvet. It is not only light but also warm."

Yesterday, in a supermarket in downtown Zhoukou, the promoters pointed to the warm underwear on the shelves and bought them one by one.

When asked what kind of material the velvet is made of, the salesperson said, "this is a trade secret. We can not say it."

Recently, a reporter interviewed found that at present, there are dozens of warm underwear varieties on the market in Zhoukou, with dozens of dollars in price and hundreds of dollars in price. In many slogans of thermal underwear, there are "Sam", "modal", "golden velvet" and so on.

Is there any relevant industry standard for thermal underwear? Yesterday, the reporter interviewed Cheng Liang, responsible person of the Municipal Bureau of quality and technical supervision.

"According to the regulations, no matter what kind of thermal underwear made of thermal insulation, the outer package must be marked with the" warmth rate "and the" unit weight ".
