In the dark night, Ye Qingyuan's live broadcast continues.

Over time, the outdoor temperature is getting lower and lower.

Twenty-two degrees below zero!

Twenty-three degrees below zero!

Twenty-four degrees below zero!

Twenty-five degrees below zero!

...

Time flies late into the night.

In these few hours, the audience fully realized the strength of Ye Qingyuan's outfit.

During a blizzard of minus 25 degrees, a single dress and a pair of pants stood in the blizzard, and the body temperature remained normal.

This insulation effect is simply terrifying!

At 10:30 in the middle of the night, Ye Qingyuan's test ended.

Ye Qingyuan went back to the hotel and chatted with the audience: "After testing for so long, everyone must be curious about why this down suit is so strong.

I'm very clear that the reason why this down suit is amazing is because the stuffing is "fire duck duck down".

This new duck down keeps warmer effect ten times that of ordinary duck down!

The warmth effect of high-quality fire duck duck down is more than ten times that of ordinary duck down!

As for higher-level duck down, the warmth effect is a hundred times that of ordinary duck down!

You heard it right, it’s just so exaggerating! It’s just so unreasonable!”

At the end, Ye Qingyuan's mouth and tongue were dry and his throat was inflamed.

In order to keep the live broadcast audience active, he has been interacting with the audience.

After several hours of continuous water, I didn’t drink a sip of water and urgently needed to replenish my body.

He said hoarsely: "I chatted with you for a long time. I'm almost thirsty. Go into the house to drink water first."

[I never expected that there would be black technology in the down jacket industry.]

【Although it is unbelievable, the facts are silly.】

【What awesome duck.】

[Little brother, I have water, do you drink it? ~]

[The ancients said, drinking water and thinking about the source, where did this water come from?]

【Wonderful! Wonderful!】

[Take the master to accept me as your disciple! Please! I want to speak as amazing as you! (Crying and hugging my thighs)]

Ye Qingyuan's mouth twitched when he saw the barrage.

B station barrage, familiar recipes, familiar taste.

After he returned to the house, he 'gudong Gudong' fed a glass of water, and after drinking the water, he went straight to the topic: "The strongest down jacket on the surface revealed the secret of the time!"

Ye Qingyuan took off his clothes and changed into regular clothes. During the barrage, there was another howling of ghosts and wolves.

It is worth mentioning that there are many yellow font barrage.

After he changed into ordinary clothes.

"Bang!"

Lift your right hand and click your finger. The picture on the right half of the live broadcast room changed from the body temperature structure to the down jacket.

Ye Qingyuan said: "The reason why this down jacket is special is because of the filling inside.

Ordinary down jackets are filled with duck down, and this down jacket is filled with "fire duck duck down".

Although they are all duck downs, the effects are completely different.

The fire duck duck down not only keeps warm and locks the temperature, but also has a breathable effect that is not the same as that of ordinary duck down.

It is simple to say that warmth and breathability are actually contrary to these two requirements, and it is very difficult to make such clothes well.

Because of the good warmth effect, the density of the clothes must be very high.

This will make the breathability worse and you will feel boring after wearing the clothes.

Good breathability, the gap between textile fibers or coatings becomes larger, and the insulation effect will decrease.

The simplest example-

Hole shoes and mesh shoes for summer.

This kind of shoe is very breathable, but you can't expect it to keep warm, right?

By the same token, if the warmth effect is good, you cannot expect to have particularly good breathability.

High-end down products on the market promote good warmth and breathable effects, which is just a consideration.

Just like a high-end game player can take into account the training, but you can't expect this player to play world-class competitions and win you a championship.

You can truly achieve the ultimate in keeping warm and breathable on a down jacket, rather than taking into account both, except for the strongest down jacket on the surface.”

Ye Qingyuan took a sip of water and continued: "The reason why the strongest down jacket on the surface can do these is the core element of the fire duck down.

Each turquoise duck duck down has hundreds of millions or even more than one billion triangular tiny pores on the spherical fibers.

These spherical fibers have tiny triangular pores that absorb heat emitted by the human body, causing the turtle duck down to expand.

When the temperature outside is low, such as single digits of temperature and below zero, the expanded turtle duck duck down will form an insulation layer to prevent the invasion of cold air from outside."

With Ye Qingyuan's interpretation, the picture on the right half of the live broadcast room produces an animation effect.

The fluffy fire duck down in the interlayer of the clothes absorbs heat and becomes more fluffy, forming a high-density insulation layer, which turns into a flame special effect.

The strong wind blows to the down jacket from the outside, and it is impossible to break through the blockade of the flame special effect of the insulation layer.

The ultra-low temperature and cold air from the outside world wanted to penetrate the down jacket, but was blocked by the special effect of the insulation layer flame.

[I'm a little confused, why do there are special effects on the live broadcast screen?]

【Video plug-in?】

【Don’t ask, it’s black technology!】

[Not to mention, this form of live broadcast is even more advanced.]

【I want a little brother's plug-in, it looks very fun~】

【Brother, am I thinking too much?】

【No, sister, can you drive up to 120 yards like this?】

【Asir, it’s her that hit me!】

[You are right, you, please park on the side and accept the Diaocha!]

Ye Qingyuan glanced at the barrage and ignored the audience's jokes for the time being.

He continued: "The reason why I can stay in a blizzard over minus 20 degrees Celsius is because this insulation layer protects body temperature.

Because of the presence of the insulation layer, even though I was in a blizzard, my skin covered with clothes did not feel the strong wind. Instead, I was always hot and my body temperature remained normal.

In this case, you are not afraid even if your head and hands are exposed to the blizzard.

Because the body temperature is not unbalanced, the body will automatically adjust the temperature to ensure the temperature of the head and hands.

Many friends should have had this kind of experience. Their hands were cold, but after a while, they suddenly became hot and became hot. This is the automatic temperature adjustment of the body.

Furthermore, people are not afraid of cold heads and feet. The colder they are, the clearer their heads are.

I am afraid that my head is hot and my feet are cold. This state of mind makes it easy for my body to have problems.

The above is the principle of the super warm effect of the fire duck down, and the principle of breathability is also very simple.

The triangular tiny pores on the ball-shaped fibers of the fire duck duck duck duck plump will not only absorb the heat emitted by the body, but also release the heat absorbed.

When the heat absorption causes the turtle duck down to expand to the maximum extent and cannot continue to expand, and the body is still dissipating heat, the turtle duck down will absorb heat while dissipating heat.

The turtle duck down on the body continues to absorb heat, enlarges the tiny triangular pores on the ball-shaped fibers of the outside world, and discharging excess heat to the outside world, thus forming directional heat dissipation.

This will ensure that the skin surface temperature is constant and will not easily sweat.

Compared with wet and sticky heat on the surface, dry body surface is more conducive to health.”

【There is also this kind of black technology?】

【I believe it (dog head)】
