"The thick down jacket is equivalent to 9 degrees cashmere, and the thick cashmere sweater is 4 degrees..."

A dress law.

Rule: does clothing have "temperature"?

Recently, a "dressing rule" has been forwarded frequently on micro-blog: "the thick down jacket is equivalent to 9 degrees centigrade, the thin down jacket is equivalent to 6 degrees centigrade, the thicker elastic cotton padded dress is 5 degrees, the thick sweater is 4 degrees, the cotton vest is 4 degrees, the fleece coat, the thin coat is 3 degrees, the thick cotton sweater is 2 degrees, the thin cotton sweater is 1 degrees, and so on, if the temperature is 22 degrees, then wearing a short sleeve and a thin coat can be: 22+1+3=26, control at 26 degrees."

The "dressing rule" has been pmitted by tens of thousands of websites, and the first response many people see is "interesting" and "practical".

Some netizens said, "I have the choice of fear card, which is very suitable for this standardized calculation."

Netizen Tung te said: "for reference, it is very helpful for comrades who often run north and south, and the method of calculating temperature can be used for packing."

However, many netizens questioned this.

Some netizens counted out the bill: "no wonder it is always so cold at 0 degrees, thick down jacket + woolen sweater + thin cotton sweater =9+4+1=14".

To wear thick down clothing + two sweaters + fleece sweater + three thick cotton sweater =26 degrees. "

Another netizen shelled directly: "the difference between the new one and the old one is very big. It's warm and warm. It mainly depends on bulky degree, not material.

Anyone who has learned thermodynamics knows it! "

Response: "dressing law" is not rigorous.

Is there any temperature in clothes? A reporter asked a lot of clothing manufacturers, and the boss heard it all fresh, no one could tell.

The staff of the China Apparel Association and the Beijing garment and textile industry association also said, "there is no such statement in the industry, nor is there a definition.

How much is the heat of the clothes? This is not a national standard. "

"I also received this" dressing rule "in my mobile phone newspaper, which is too imprecise.

The staff of the national textile products quality supervision and testing center told reporters that there is no temperature standard in the testing standard of clothing.

The staff said that the warm and warm clothes mainly depend on the four parameters, such as the heat preservation rate, thermal conductivity, thermal resistance value and Crowe value. "If people take clothes to detect warmth, we are also testing these four items."

For the common people, the heating rate is the most intuitive parameter, this is calculated through the professional calculation formula, and the clothing purchased in the shopping mall, and will not label the warmth rate.

The staff of the national textile products quality supervision and Inspection Center said: "only the thermal underwear has the requirement of heat preservation rate, the standard is above 30%, while other clothing shoes and hats do not have the relevant standards of the heat preservation rate."
