360-degree analysis of duvet knowledge

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

1. What is a duvet

Down Quilt refers to the quilt with down as the main filling material, and the down content shall not be less than 50%.

2. The characteristics of the duvet

Good heat preservation: Because each feather silk of down is made up of thousands of tiny scales superimposed. Each scale is hollow, and these tiny pores are filled with a lot of still air. Due to the lowest conductivity coefficient of air, a natural barrier is formed, which prevents the convection of hot and cold air. These still air can absorb the heat emitted by the human body and isolate the intrusion of cold air from the outside world. This is why down has good thermal properties.

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

Good temperature regulation: Since down is a three-dimensional spherical fiber, which is full of a large amount of still air, it can shrink and expand with the change of temperature, resulting in the function of temperature regulation. The duvet can be used at a temperature of 25 degrees to minus 40 degrees.

Powerful moisture absorption and dehumidification: Down has strong moisture absorption and desorption, and will automatically cycle to absorb, diffuse and evaporate under different temperatures and humidity. Due to the structure of down, it has a large surface area, so it will quickly dissipate after absorbing moisture. In addition, the down itself contains a certain amount of oil, which has moisture-removing properties. In addition to absorbing the sweat discharged from the human body during sleep and quickly expelling it, the duvet can also automatically adjust the temperature inside the quilt, and has the function of absorbing and removing moisture, keeping the human body dry and preventing rheumatism. The comfortable relative humidity is 40-70%. In southern my country, the relative humidity is relatively high, up to 90% in some areas. Therefore, diseases such as rheumatism, arthritis, neuralgia, and eczema are quite common. The use of duvets can effectively reduce such diseases. morbidity.

High bulkiness: The bulkiness refers to "the volume occupied by a certain amount of down (feather) under constant pressure in a container of a certain diameter." Here, it generally refers to the elasticity of the quilt, which is a measure of the quality and grade of the duvet. key indicators. The level of bulkiness is related to the comfort of the quilt and the performance of heat preservation, temperature regulation, moisture absorption and dehumidification. For example: quilts made of linear fibers such as chemical fiber, cotton, wool, silk, etc., after 1-2 years of use, due to the poor compression resistance of the linear fibers, it is easy to harden, the bulkiness is reduced, the size is shortened, and the material degrades quickly. Therefore, Its functions of heat preservation, temperature regulation, moisture absorption and dehumidification are also reduced. Because the unique down is three-dimensional spherical and rich in oil, it will never be hardened after perennial 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 it cannot be washed with water, while the duvet is washable and easy to dry; not afraid of fire - down is animal protein, below 100 degrees Celsius temperature (such as cigarette butts) will not burn.

Durability and economy: A good duvet has a lifespan of up to 30 years for its anti-velvet fabric, and up to 70 years for filled down. It can be passed down for three generations in Europe, and the average annual cost of use is very low, and no matter the comfort level. , sense of value, average cost of use and durability are better than other quilts.

Good fit: Because the duvet is light, soft and comfortable, it has good fit to the human body, making the body feel warmer and more comfortable. In addition, the sewing process of the down quilt is not like other traditional quilts, but it is made into an independent square 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 convenient to use or store, and it is easy to store.

According to the research results published by French scientific research institutions: At present, there is no thermal insulation material in the world that exceeds the thermal insulation performance of down. The special structure of down allows the down to be filled with a large amount of still air. Since the air has the lowest thermal conductivity, down has the best thermal performance.

Down also has the good performance of moisture absorption and divergence that other thermal insulation materials do not have. It is determined that the body constantly emits sweat when sleeping. An adult emits about 100 grams of sweat overnight. Down can continuously absorb and discharge the sweat released by people, so that the body does not feel wet and stuffy.

Down is full of elasticity. In the test of down with a 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. The special health properties of the duvet

360-degree analysis of duvet knowledge

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

Europeans regard down duvets as health care products for treating joint pain, neuralgia, hypertension and other diseases, while French and German scientific research institutions regard down duvets as the most ideal bedding.

Li Shizhen, a great Chinese medical scientist, mentioned in the "Compendium of Materia Medica": "Choose goose belly down for clothing and quilt, which is soft and cold in nature, especially suitable for infants' panic." Explained from a modern point of view, the health care of down quilts The function is determined by the unique soft warmth and good performance of moisture absorption and diffusion.

Sleeping with a duvet covered will make you feel warmer and more comfortable, without pressure, normalize blood pressure, stabilize the central nervous system, and soon enter a sweet sleep.
