What we call the smell of the sun is actually the smell of dead microorganisms mixed with ozone. From this we can also learn a common sense that the quilts that have been sunken cannot be covered immediately. When is the best time to dry the quilt? How long does it take to dry quilt?
When is the best time to dry quilt?
The best time to dry quilt on sunny days is from 11 am to 2:30 pm. If you want to dry it for a while, if the quilt is too late, cold and dampness will invade, and the dew will moisten it, which will be counterproductive. Not all quilts can be exposed to the sun. For example, synthetic fiber cotton wool should be avoided in sunlight. Down quilts and wool quilts must not be used to bask in the sun, because the high temperature of the sun will change the oil contained in down and wool, produce a rotten smell, and it will also deteriorate and become a breeding ground for lice bacteria.
Pay attention to details when drying quilts
The quilt is prone to retain some human dandruff, sweat, etc. Even if it is a clean quilt, it will breed millions of mites without being sunburned for 3 consecutive months, and the ultraviolet rays in the sun can effectively sterilize.
In addition, since various artificial boards and wooden furniture contain chemical substances such as formaldehyde, over time, the quilt placed inside will absorb a large amount of free formaldehyde. So, choose a sunny day and take the quilt to the sun to dry. It will not only kill the harmful microorganisms in the quilt, but also make the cotton fibers stretch and fluffy, allowing you to fall asleep under a soft quilt with "sun smell" “
When drying quilts, you should also pay attention to the following details:
First, the quilt can be directly dried. From 11 a.m. to 2 noon, the sun is the most abundant. If you dry the quilt during this period, the cotton fiber will expand to a certain extent. Don't expose the duvet and wool quilts to the sun, just dry them in a ventilated place such as the balcony for 1 hour.
Secondly, chemical fiber fabrics or quilts with mixed fiber fabrics should not be exposed to the sun, because chemical fibers will release chemicals at high temperatures for a long time. This type of quilt can be covered with a thin cotton cloth first and then dried to protect the quilt from damage. In addition, the wool quilt and down quilt have very good hygroscopicity and moisture removal properties, and it is best to cover a piece of cotton when drying.
Finally, do not slap the quilt when it is sunburned. Because the fibers of cotton are thick and short and easy to break, if you beat them hard, the fibers will turn into cotton dust and run out; synthetic fibers are generally thin and long and easy to deform. Once the fibers shrink and do not easily restore after being beaten, they become a piece of slatted; down quilts cannot be beaten, otherwise the down will break into a small “ feather dust ” thus affecting the warmth effect. In addition, after the quilt is slapped, dust on the surface and mites will fly up, which can easily cause allergic reactions. So, just brush with a brush to remove dust.
How long does it take to dry the quilt?
After rainy days, sunbathing in the warm sunshine, the quilt has the smell of sun and green trees. So, how long should the quilt be suitable and better?
1. It is best to dry quilts in sunny winter from 10 am to 2:30 pm. If you want to dry it for a while, if the quilt is too late, cold and dampness will invade, and the dew will moisten it, which will be counterproductive.
2. Put the quilt on the rope and the quilt is in it, mainly in the quilt. You will dry the quilt again at 1:00 pm and you can collect it at 4:00 pm. It is best to pat it when collecting it. If it is dirty, it is best to have sticks or something to beat it. The purpose of drying quilts is to use ultraviolet rays to kill bacteria in the quilt. I often dry the quilt and it is comfortable to cover it when I sleep.
3. When drying quilts, in order to avoid direct sunlight, you can cover them with a bed sheet, but turn the quilts over halfway so that both sides can be evenly sunny. Kapok is twice a week and has sunlight for three to four hours. Combined fiber cotton is once a week, and it is ideal to dry for two to three hours.
4. The wool is sunburned twice a month and in a cool place for two hours. The feathers are dried once a month, thirty minutes in summer and one hour in winter, and they are hung in a cool place.
5. Feather quilts can also be placed on chairs and placed indoors, as long as they can be ventilated, there is no problem.
6. After the quilt has been sunburned, there are three changes:
1. The moisture in the quilt is dried;
2. The microorganisms in the quilt are killed by the ultraviolet rays in the sun;
3. The oxygen in the quilt is stimulated by the ultraviolet rays to become ozone. The final conclusion is that the sun smell is the smell of the dead smell of microorganisms mixed with ozone.

What is the smell after sunbathing?
Since the quilt that has not been sunbathed over time does not have the sun, it means that this smell must be produced by sunbathing. So, what is the smell after sunbathing? The editor will take you to know.
Sunlight irradiation will generate heat, and it also contains ultraviolet rays of multiple wavelengths of 100nm~400nm, which are divided into four stages: UVA (315-400nm), UVB (280-315nm), UVC (200-280nm) and vacuum ultraviolet rays (100-200nm). UVC can kill bacteria and stimulate oxygen to produce ozone. The main changes in the quilt are:
1. The moisture in the quilt is dried
2. The microorganisms in the quilt are killed by the ultraviolet rays in the sun
3. The oxygen in the quilt is stimulated by the ultraviolet rays to become ozone
The sun smell after the quilt is sun-dried
The first type is dried
. According to our daily experience, the process of water evaporation will not produce any odor, and this is eliminated.
The second type, can ultraviolet rays kill microorganisms? The answer is yes. The nucleus of microorganisms contains RNA and DNA. Both of these nucleic acids can absorb high-energy short-wave ultraviolet radiation. This absorption can create new bonds between adjacent nucleotides, thereby forming bimolecules or dimers. In this way, the genes of microorganisms are messed up and cannot perform normal protein synthesis, resulting in death. Therefore, if a person is exposed to ultraviolet rays for a long time, skin cells will also be damaged, and bacteria and viruses will directly return to the west. The disinfection effect of ultraviolet rays on the quilt is very obvious. So will microorganisms produce odors after death? Is this smell what we call the sun?
The third type is ozone. We all know that ozone has a irritating odor. There is air inside the quilt, and the air contains oxygen. When oxygen is exposed to ultraviolet rays with a wavelength of 243nm, the chemical bonds will break and produce ozone. Therefore, the smell of quilt after sunburn must also contain the smell of ozone. But ozone is a irritating smell, why is the quilt not irritating at all? That's because the air will flow, and most of the ozone produced will drift with the wind. The rest will absorb 210nm to 290nm and photolysis, so in the end, only a small part of the ozone is left, so the odor is very weak and there will be no stimulation.
That's it. What we call the smell of the sun is actually the smell of dead microorganisms mixed with ozone. From this we can also learn a common sense that the quilts that have been sunken cannot be covered immediately. Because the remaining microbial remains and ozone may affect health, you must knock them and use a broom to sweep them.
