The Secret Formula For Choosing Winter Clothes And Down Garments

Here world

The little weave of the net tells you that the down jacket has such a secret formula!

Internet has been circulating such a "dressing formula". The thicker down jacket is equivalent to 9 degrees centigrade, the thin down jacket is equivalent to 6 degrees centigrade, the thicker elastic cotton jersey 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, and the thin cotton sweater is 1 degrees.

If the temperature is 22 degrees, then wearing a short sleeved T-shirt and a thin coat can be: 22+1+3=26, control at 26 degrees. "

The survey found that this formula was first derived from a January 2011 report entitled "calculating the dressing temperature of a garment to wear a down jacket equivalent to +9 degrees". It is a doctor in the Department of internal medicine of Hangzhou Traditional Chinese Medical Hospital who divided his daughter's clothes according to the temperature. The medical student explained that when the temperature was 26 degrees, wearing a T-shirt was just good.

On this basis, if the temperature drops by 3 degrees centigrade, a thin coat will be just fine, and a 4 woolen sweater will be lowered by 4 degrees centigrade.

This means that the thin coat represents 3 degrees, and the thick sweater is 4 degrees. The formula is analogical.

Is this formula scientific? For this reason, Professor Zhang Hui, Professor of the school of clothing art and engineering of Beijing Institute Of Fashion Technology, is "obviously unscientific".

Zhang Hui believes that the difference between body temperature and environmental temperature is different from that of the human body. It is unscientific to measure the warmth of clothing only by feeling.

Well, can the warmth of clothes be measured? Zhang Hui explained that the unit used in the industry described thermal insulation is not centigrade but "Crowe".

A person who is sitting quietly or doing light mental work is metabolized at 209 thousand and 200 Jiao / hour. At room temperature of 21 degrees, relative humidity less than 50%, and wind speed less than 0.l m sec, if the feeling is comfortable, the temperature of this person's clothing material is 1 CR.

That is to say, in theory, the clothes of 1 Crowe in 20 degrees or so are no problem.

By analogy, the clothes of 2 Crowe can be worn at around 10 degrees Celsius.

However, even the jacket and the crook value of the trousers can not draw the overall thermal insulation of the two garments, because clothing and clothing are overlapped and not evenly covered after wearing on the human body, so the warmth retention of many clothes after wearing is not the crook value of the single piece but the style and structure of the garment and the way of wearing it.

Down jacket is not as thick as possible!

In the cold winter, the down jacket Market is getting hot.

All kinds of slogans are dazzling.

Consumers can not help but wonder when they are buying, "is the light feather down clothing warm?"

But do you really choose the down clothes? Many people think the thicker the down clothes, the better, is that true? Here are some misunderstandings for the down clothes.

Myth 1: the higher the amount of cashmere, the better.

According to feather

The national standard of clothing requires that the down garments must be marked down, including cashmere and cashmere.

The percentage of cashmere and cashmere yarn in the down is less than 50%.

The same kind of down garment with higher cashmere content has better thermal insulation effect.

However, Secretary General Qu Fei said that the average consumer's choice of 70% to 80% of the amount of cashmere can meet the demand.

Myth two: thick down jacket is warmer.

The amount of filling is the total weight of all the eiderdown, which is related to the size, length and style of the clothes. The national standard does not impose a mandatory requirement on this index.

But what needs to be reminded is that the more the filling, the heavier the clothes, the warmer the down jacket is.

Because with the increase of packing density, the heat loss caused by conduction of filler also increases.

Improving the fluffiness of down filling is the key to improving warmth retention. The higher the bulkiness is, the more heat insulation the feather contains, so the better insulation performance.

This is why some light down clothing on the market has been keeping warm in recent years.

Some of the eiderdown feathers are filled with woolen feather silk, velvet silk and crushed wool, even if the amount of cashmere is the same, its fluffiness also decreases.

At present, the general price of the down jacket, bulky degree is about 450 - 500, the price is slightly higher down clothing, fluffy can reach 600 - 900.

Myth three: down jacket feels no feather stems, the softer the better.

The Deputy Secretary General of Qu Fei said that in fact, the quality of down has certain limits of small hair stalks is very normal, if the touch is particularly soft, a bit can not be touched, such products should be cautious to buy.

Because some manufacturers will break leftovers, fluffy cotton and feathers, and then fill them in clothing as a feather to deceive consumers.

Not only can not achieve good thermal effect, health may not meet the standards.

Having learned the above misunderstandings, consumers are much easier to choose.

Here are some tips for judging the quality of down jacket.

A look: whether there are product quality labels, testing reports, etc., labels on the down type, including the amount of cashmere and cashmere volume is clearly marked.

Two touch: the down jacket with good quality feels soft and has a complete hairy sheet. It has feathered stems but not much. At the same time, it has to ensure the fine and soft hair.

Three press: press down the down garment with your hands, then let go.

If the rapid rebound is restored to the original state, it shows that the down is well fluffy.

The poor resilience and heavy feeling in the hands indicate that the amount of cashmere is low or may be mixed with a certain amount of wool or crushed wool.

Four Pat: beat down a down jacket. If there is a feather running out or a dust overflow on the needle, it means that the fabric is too bad to prevent the fabric from being drilled or the stitch is too big.

Some down jacket fabrics are not duffed and waterproof, but with poor air permeability, moisture is not easy to distribute, and it is not easy to dry after washing.

Five smell: nose close to down jacket carefully smell, if there is a distinct smell or smell, it may fill the poor quality down, it is recommended not to buy.

Six weigh: weigh the weight of the down jacket, and the lighter the weight, the better the volume.

Finally, we should pay attention to the tailoring when buying. The more lattices for fixing down, the better. Otherwise, after several times of washing, the down may be lump and droop like a gourd shape.

Those who plan to travel long distances should choose small down, light weight, compress down in their backpacks, and those who need to stay in cold weather for a long time should choose the long section.

It is better to wear a down coat with more wearable pockets and more personal belongings. The hat should have a burr to protect the wind, while the down coat vest should choose a relatively close fitting one.
