"Can you still stand having a swimming ring? A flat belly, double S-curves, and a ×× honeycomb warm corset let you spend the winter in spring ... "Recently, a TV advertisement for a warm corset with a price of nearly 1,000 yuan attracted many citizens. However, this newspaper received feedback from the public that the high-priced warm corset not only does not lose weight, but also does not keep warm!

A few days ago, the experiment designed by the students and teachers of Grade One in Xiangming Middle School proved that the thermal performance of this kind of honeycomb warm clothing is not as good as that of two ordinary cotton sweaters in 30 yuan.

Helpless experience

Consumers who trust warm fitness clothes have caught a cold.

Ms. Liu, who lives in Putuo District, told reporters that before the Spring Festival, she saw an advertisement about the honeycomb warm corset. According to the advertisement, this kind of thermal bra "has the advantages of fabric heating, exercise heating and honeycomb heat storage", "light and warm, slim figure, and can spend the winter in spring clothes".

Looking at the advertising heroine wearing a short skirt, she smiled confidently in the environment of MINUS ten degrees, while the people wrapped in thick down jackets around her could not stand the cold. The advertisement also said that after wearing the corset, not only will you not be afraid of the cold, but your figure will also get better, and even if you wear it for a while and then take off the corset, you will not go out of shape. "The advertisement also said that due to the Spring Festival promotion, the warm corset with the original price of nearly 1,000 yuan was discounted to 500 yuan." Unable to withstand the temptation of TV advertisements, Ms. Liu bought a set of ×× honeycomb warm corset by telephone.

Due to the unusually cold around the Spring Festival in Shanghai for many years, many women who love beauty are fascinated by this kind of clothes. On New Year's Day, Ms. Liu took off her heavy down jacket and put on a new warm corset and woolen coat. The temperature was below zero that day, and my face turned purple after going out all day. On the second day of the Lunar New Year, Ms. Liu caught a cold. "After wearing it for half a month, it not only has no slimming effect, but also has the same warmth retention performance as ordinary cotton sweaters. Have I been cheated? "

The dealer called Taiji and said he didn't know the phone number of the manufacturer.

"The actual effect is too different from the advertisement, and the merchant should return it." However, Ms. Liu told reporters that after the dealers heard about the situation, they said that the products were not problems in the distribution process and had nothing to do with them; If you are not satisfied with the product, you can directly report it to the manufacturer. "I bought it from the dealer. Where can I find the manufacturer? " Ms. Liu feels very helpless.

Yesterday afternoon, the reporter contacted the dealer and dialed the service number. The operator heard that he had come to ask about the after-sales quality problem and hung up. The reporter dialed the phone number of another company that distributes the same brand of corsets. The salesman with a northern accent said, "Everyone buys clothes only when they see advertisements. We are responsible for collecting money and shipping, and other manufacturers should be responsible. " When the reporter asked about the phone number of the manufacturer, the salesperson said, "We don't know the phone number of the manufacturer either."

The reporter then tried to contact the manufacturer marked on the product packaging box-an information technology company in Shanghai, but the company was not registered in 1 14, and the contact information was not announced by other means.

The thermal performance is lower than that of ordinary underwear.

Coincidentally, this advertisement of honeycomb warm corset also attracted the attention of Song Yichao, a senior one student in Xiangming Middle School. "Is it really as amazing as advertised?" Xiao Song, a member of the school creation society, bought a set of honeycomb warm clothes to solve the puzzle, and joined hands with Mr. Huang Zengxin, the creation society, to solve it together. After more than a month of repeated thinking, a complete set of "inspection experiments" was officially released. "Simple experiments can expose the lies in advertisements. The thermal performance of this bra is no better than that of underwear with a set of 30 yuan. " Song Yichao told reporters confidently.

Teachers and students respectively "put on" clothes for two barrels of pure water with the same size and the same temperature of 37℃, one of which is a honeycomb warm-keeping fitness suit bought at a high price, and the other is an ordinary cotton sweater with a total price of 30 yuan. Let two buckets of water cool naturally at the same temperature to see which clothes have good warm-keeping performance. 14 hours later, according to the data measured by the automatic temperature recorder, the water temperature of "wearing" ordinary cotton sweater was 24℃, while the water temperature of "wearing" honeycomb thermal bra was reduced to 22℃.

In order to make the experiment more rigorous, teachers and students inserted the electric heater into two barrels of water of the same quality and kept the water temperature at 45℃ all the time. As a result, at the same time, the bucket of water "wearing ordinary cotton sweater" consumes 0.3 degrees of electricity, while the bucket of water "wearing honeycomb warm clothes" consumes 0.5 degrees of electricity. "This clearly shows that the thermal performance of corsets is even lower than that of ordinary underwear."

The fabric is not hot, let alone slim.

The advertisement of honeycomb corset also claims that warm clothing can not only heat the fabric, but also consume more energy for daily small movements and increase exercise calories anytime and anywhere. In the parts of human body where fat is easy to accumulate, honeycomb structure is adopted to relax and store heat. "Not only a fever, but also exercise to lose weight, which is also the key to our question," Xiao Song told reporters.

They made a refrigerator-sized incubator in the school laboratory, controlled the indoor temperatures at 10℃, 0℃ and-10℃ respectively, and then put the warm clothes on a device simulating the movement of human arms and kept shaking their arms. After several hours, the temperature of the simulated arm hardly changed.

In addition, teachers and students also designed an experiment of continuous stretching of warm clothing, and found that the temperature of the simulated arm remained unchanged after the clothing was deformed. "This just shows that the fabric itself will be hot and it is also false propaganda."

"If the manufacturer has any questions about our experiment, please come and question. Let's do experimental verification together! " Teachers and students are full of confidence in their "anti-counterfeiting experiment".

[Expert] Beware of irrelevant propaganda

"A thin dress can be used as several down jackets, which should be impossible." Mr. Zhang, an engineer of a well-known clothing company, said that although the warm-keeping performance of fabrics can be gradually improved through related processes, the improvement is limited. So far, there should be no fabric equivalent to a layer of down jackets: "Even if someone develops it, the price can't be lower than 1000 yuan."

At the same time, health experts say that it is unscientific and unrealistic to lose weight by shaping clothes. Body-shaping clothes may also compress organs while squeezing fat. Wearing slimming clothes for a long time can not only achieve the purpose of slimming, but also may cause harm to the body. Experts remind that many direct selling products are boasting that they can lose weight effortlessly, and the principles they list have no scientific basis. I hope consumers will carefully consider the credibility of publicity.

[Lawyer] It is illegal to sell an enterprise without bidding.

It is understood that this marketing model, in which only sales calls are widely advertised and sellers and manufacturers turn a blind eye, is very popular in the market now. Mainly based on health care products, products are exaggerated in the sales process. False propaganda, and then deceive consumers in the market, consumers are deceived, and when they come out to defend their rights, there are only sales calls, and no one knows who the sellers and manufacturers are. When making a sales call, the relevant personnel shirked their responsibilities on the grounds that they had just delivered the goods. Consumers go back to sellers and manufacturers and find that there is no shadow of them from beginning to end, and there is no way to defend their rights.

"It is illegal to book a phone number without indicating the sales company." Yesterday afternoon, the reporter consulted a lawyer and learned that the State Administration of Radio, Film and Television explicitly requested that "the content of TV shopping programs should be true and legal, indicating the name of the business and sales company promoting the product and the approval number of related products." At the same time, according to the relevant provisions of the Advertising Law, if an advertiser knows or should know that advertising is illegal, he shall bear joint liability according to law. In addition to requiring an advertisement review sheet and strictly examining the qualifications of advertisers, TV stations must also strictly implement the relevant national "no broadcasting" regulations, otherwise TV stations will bear the responsibility of publishing false advertisements.
