Why is down bedding so popular in developed countries?



According to the official statistics of the International Down Association, the penetration rate of down bedding in developed countries, developing countries and poor countries is very different: the penetration rate of down bedding in Japan is 103%, that in the United States is 87%, and that in other developed countries such as Europe and America Basically around 50%. my country is one of the world's economic powers, but the penetration rate of down bedding in my country is less than 5%, and the penetration rate of other developing countries is lower than that of my country.

1. What is down bedding

Down bedding refers to bedding products with down as the main filling material.

Down comforters with the lowest down contentNot less than 50%.

2. Characteristics of down bedding

Good heat preservation: each feather silk of down is made up of thousands of tiny scales. Each scale is hollow, and these tiny pores are filled with a large amount of still air.

Since air has the lowest conductivity, it forms a natural barrier that prevents hot and cold air from convecting. The still air can absorb the heat emitted by the human body and isolate the invasion of cold air from the outside. This is the reason why down has good thermal performance.

Soft, no feeling of oppression: The duvet is soft in texture, and a double duvet weighs about 2.5 kg (the weight of the cotton quilt is about 4.8-7.2 kg, and the weight of the silk quilt is 3.6 kg), which is currently the lightest natural warm bedding on the earth. It will not cause pressure on the human body (heart, lungs), can promote blood circulation, and is easy to turn over. It is most suitable for children, pregnant women, the elderly, those who have poor sleep or those with high blood pressure.

Good thermoregulation performance: Since down is a three-dimensional spherical fiber, which is filled with a large amount of still air, it can shrink and expand as the temperature changes, resulting in a thermoregulation function.

The duvet can be used at a temperature of 25 degrees to minus 40 degrees.

Strong moisture absorption and dehumidification: down has strong moisture absorption and dehumidification, and will automatically cycle through moisture absorption, diffusion and evaporation under different temperatures and humidity. Due to the large surface area of ​​down due to its structure, it will quickly dissipate water after absorbing it. In addition, down itself contains a certain amount of oil and has moisture-wicking properties.

In addition to absorbing the sweat from the human body during sleep and quickly discharging it, the duvet can also automatically adjust the temperature inside the quilt. It has the function of moisture absorption and dehumidification to keep the human body dry and prevent rheumatism. The comfortable relative humidity is 40-70%. In the south of my country, the relative humidity is relatively high, as high as 90% in some areas. Therefore, diseases such as rheumatism, arthritis, neuralgia, and eczema are quite common. Using duvets can effectively reduce such diseases incidence rate.

High bulkiness: The bulkiness refers to the volume occupied by a certain amount of down (feather) under constant weight pressure in a container of a certain caliber.

"Here generally refers to the elasticity of the quilt, which is a key indicator to measure the quality and grade of the duvet. The level of bulkiness is related to the comfort and performance of the quilt, such as heat preservation, temperature adjustment, moisture absorption and dehumidification. For example: chemical fiber, cotton, wool, Quilts made of linear fibers such as silk, after 1-2 years of use, due to the poor compressive resistance of the linear fibers, they are easy to harden, the bulkiness is reduced, and the size is shortened, and the material degrades quickly. Functions such as dehumidification are also reduced.

Because the unique down is three-dimensional spherical and rich in oil, it will never harden after years of use, which can ensure its function as new for a long time.

Good safety: not afraid of water - cotton is easy to absorb water, it is not easy to dry after getting wet, and cannot be washed, while the duvet is washable and easy to dry; not afraid of fire - down is animal protein, and it can be dried under 100 degrees Celsius Temperature (such as cigarette butts) is not burning.

Durability and economy: A good duvet has a service life of 30 years for the anti-down cloth and 70 years for the filled down. It can be handed down for three generations in Europe. The average annual cost of use is very low, and regardless of the comfort level , sense of value, average cost of use and durability are superior to quilts made of other materials.

Good fit: Due to the light weight, softness and high comfort of the duvet, the body fits well, making the body feel warmer and more comfortable. In addition, the sewing process of the duvet is not in the flake shape of other traditional quilts, but in an independent grid shape, so it has the best fit.

Easy to store, does not take up space: the duvet has excellent elasticity and the largest compression ratio, it is very easy to take or store, and is easy to store.

Down bedding compared to other bedding


Warmth Comparison

According to the research results released by French scientific research institutions, there is no thermal insulation material in the world that exceeds the thermal insulation performance of down. The special structure of down allows a large amount of still air to be filled in the down. Since the heat transfer coefficient of the air is the lowest, the thermal performance of the down is the best.

Air permeability comparison

Down also has the good performance of moisture absorption and divergence that other thermal insulation materials do not have.

According to measurements, the human body continuously emits sweat during sleep, and an adult emits about 100 grams of sweat overnight. Down can continuously absorb and discharge human sweat, so that the body does not feel damp and stuffy.

Fluffiness comparison

Down is full of elasticity. When tested with down content of 50%, its bulkiness is equivalent to 3.5 times that of cotton and 2.2 times that of wool, so the duvet is not only soft and warm, but also feels good to the skin.

Comparison of service life

The service life of the duvet is 5 times that of other quilts (chemical fiber quilt, silk quilt), and its cost is only 3 times that of other quilts.

Cleanliness comparison

The washed down contains much less impurities than other materials.

3. Special health care performance of down bedding

Among the quilts made of the four natural thermal insulation materials of cotton, wool, silk and down, the duvet has the best thermal insulation performance and the best comfort.

Europeans use down quilts as health products for treating joint pain, neuralgia, high blood pressure and other diseases, while scientific research institutions in France and Germany regard down quilts as the most ideal bedding.

Li Shizhen, a great medical scientist in my country, mentioned in "Compendium of Materia Medica": "Choose goose belly fluff as clothes and quilts, which are soft and cold in nature, and are especially suitable for relieving babies' shock." The function is determined by the unique soft warmth and good performance of moisture absorption and dispersion of down.

Sleeping under the duvet will make you feel more warm and comfortable without pressure, normalize your blood pressure, stabilize your central nervous system, and soon fall into a sweet dreamland.
