According to the official statistics of the International Down Association, developed countries, developing countries and poor countries, the penetration rate of down bedding is very different: Japan's down bedding penetration rate of 103%, the United States for 87%, other developed countries such as Europe and the United States, the penetration rate is basically about 50%. China is one of the world's economic powers, but the penetration rate of down bedding in China is less than 5%, other developing countries than China's penetration rate is even lower.
What is down comforter
Down quilt is a quilt with down as the main filling material, and the minimum down content should not be less than 50%.

2. Characteristics of down comforter

Good heat retention: Because each down filament is made of thousands of tiny scales stacked on top of each other. Each scale is hollow, and these tiny pores are full of a large amount of still air. Due to the lowest coefficient of air conduction, a natural barrier is formed so that hot and cold air cannot be convected. These still air can absorb the heat emitted by the body and isolate the invasion of cold air from outside. This is the reason why down has good warmth retention properties.

Light and soft, no pressure: down comforter texture is light and soft, a double down comforter about 2.5 kg (cotton comforter weight about 4.8-7.2 kg, silk comforter 3.6 kg), is currently the lightest natural warm bedding on earth. It is most suitable for children, pregnant women, the elderly, people who do not sleep well, and people with high blood pressure.

Temperature regulation: Because down is a three-dimensional spherical fiber, it contains a large amount of static air, so it can contract and expand with temperature changes, creating a temperature regulation function. The down comforter can be used at temperatures ranging from 25 degrees to -40 degrees.

Powerful moisture absorption and wicking: Down has powerful moisture absorption and wicking properties and will automatically cycle through moisture absorption, diffusion and evaporation at different temperatures and humidity levels. Because of the structure of the down, the surface area is very large, so it will absorb moisture and quickly dissipate, in addition to the down itself contains a certain amount of oil, with moisture removal. In addition to absorbing the sweat discharged by the body while sleeping and discharging it quickly, the down comforter can automatically adjust the temperature inside the comforter and has the function of moisture absorption and wicking, which keeps the body dry and can prevent rheumatism. Comfortable relative humidity is 40-70%, and in the south of China, the relative humidity is relatively high, up to 90% in some areas, so rheumatism, arthritis, neuralgia, eczema and other diseases are quite common, and the use of down comforter can effectively reduce the incidence of such diseases.

High fluffiness: Fluffiness refers to "the volume of a certain amount of down (feathers) under constant pressure in a certain caliber of container." It refers to the elasticity of the quilt, which is a key indicator of the quality and grade of the down quilt. The level of fluffiness is related to the comfort of the comforter and the performance of insulation, temperature regulation, moisture absorption and moisture wicking. For example: chemical fiber, cotton, wool, silk and other thread-like fibers made of quilt, after 1-2 years of use, because of the thread-like fibers poor resistance to pressure, easy to knot, fluffiness reduced, and size shortening, material degradation is fast, so its insulation, temperature regulation, moisture absorption, moisture wicking and other functions also reduced. Unique down because of its own three-dimensional spherical and rich in grease, the use of perennial also never slat, can ensure its function as new for a long time.
Good safety: not afraid of water - cotton is easy to absorb water, wet after not easy to dry, and can not be washed, while down is washable, easy to dry; not afraid of fire - down for animal protein, in the temperature below 100 degrees Celsius (such as cigarette) is not It will not burn.
Durability and economy: A good down comforter has a service life of up to 30 years for the down-proof fabric and up to 70 years for the down filling, which can be passed on to three generations in Europe, with a very low average annual cost of use, and is better than other materials in terms of comfort, value, average cost of use and durability.
Good fit: Because down comforters are light, soft and comfortable, the human body fits well, making the body feel warmer and more comfortable. In addition, the sewing process of the down comforter is not like other traditional comforter tires, which are made into individual squares, so it has the best fit.

Easy to collect and does not take up space: The down comforter has excellent elasticity and maximum compression ratio, so it is easy to collect or use.

The special health properties of down duvets

Among quilts made of the four natural warming materials - cotton, wool, silk and down - the down comforter has the best warmth and the best comfort.
Europeans use the down comforter as a health care product to treat diseases such as joint pain, neuralgia and high blood pressure, while scientific research institutions in France and Germany have hailed the down comforter as the most ideal bedding.
China's great medical scientist Li Shizhen mentioned in the "Compendium of Materia Medica": "Select goose belly down for clothes, quilt wool, soft and new cold nature, especially suitable for relieving the baby's shock pain." With the modern point of view, the health function of the down quilt, is determined by the unique light and soft warmth and moisture absorption and good performance of the down.
Cover down will feel warm and comfortable, no pressure, so that the blood pressure is normal, the central nervous system to stabilize, and soon enter a sweet sleep.
