Is Duck Down or Goose Down Better?

The filling of the feather duvet cover is mainly down, which grows on the abdomen of geese and ducks, and forms reed flower-like fluff, which is called feathers in flakes. Since down is an animal protein fiber, it has higher thermal insulation than cotton (vegetable cellulose), and the ball-shaped fiber of down is densely covered with thousands of small triangular pores, which can shrink and expand with the change of temperature, resulting in the function of temperature regulation. Therefore, it can absorb the hot air emitted by the human body and isolate the intrusion of cold air from the outside world.

1. The role of the feather duvet cover

(1) Soft and warm: There is no natural thermal material in the world that exceeds the down in terms of thermal performance. In addition, the down is full of elasticity, so the thermal performance is not only soft and warm, but also feels good on the skin.

(2) Moisture absorption and divergence: The feather duvet cover is breathable and dry, and the good quality duvet has the good performance of moisture absorption and divergence that other thermal insulation materials do not have, and is called a breathable quilt. People's central nervous system can be stabilized, who will soon enter a sweet dreamland, so it also has a certain effect on beauty.

(3) When the human body is in the state of sleeping, about 170cc of water is excreted every night. Generally, the bedding will accumulate too much water soon after use, which is easy to form a breeding ground for bacteria and cause discomfort to the skin or trachea. Because the down fiber has tens of millions of triangular pores that can breathe and the surface contains waterproof grease, it can automatically shrink or expand with the change of outside temperature and humidity, and can quickly absorb the sweat and moisture of the human body and dissipate it quickly, keeping the quilt clean and human body dry. Therefore, long-term use can also prevent the production of rheumatism.

2. Is duck down or goose down better for the feather duvet cover?

Is duck down or goose down better for the feather duvet cover? Compared with duck down, goose down has large down buds, high hollowness, good bulkiness, excellent resilience, and stronger warmth retention. The down buds of goose down are generally larger than those of duck down, and the bulkiness is 50% higher than that of duck down, so the thermal insulation performance is better. Both goose down and duck down have grades, and even the lowest grade goose down is better than the highest grade duck down. Relevant experts also frankly admit that in general, goose down feather duvet covers are better than duck down feather duvet covers in terms of various indicators.

When talking about the difference between goose down and duck down, down experts pointed out that there are two aspects to the problem of duck down. First, ducks like to eat insects in water, so duck down generally has a fishy smell (called "duck body odor" by industry insiders). To remove peculiar smell, in decontamination and degreasing processes, some processing plants have even used deodorant. Although the newly bought down doesn't have the smell, the smell will emerge after a few months, and it will take at least a year for it to dissipate naturally. The goose is a herbivore, so the goose down itself has no odor problem at all, and the green environmental protection problem has been resolved from the source of the raw material. Because of the better thermal insulation and environmental protection performance of goose down feather duvet cover, most of the foreign feather duvet covers and high-end down products basically use goose down.
