1. What is down
Down is composed of many tufts of filaments that grow from the feathers without stalks. It looks more like a dandelion seed. Down is light and downy, and is used as an inner layer by geese, ducks and other waterfowl for warmth. Ground birds, such as chickens, do not produce down.
2. What is a feather
The feathers, which mainly cover the outer layer of birds, are flat in structure. A feather has a rigid shaft from one end to the other, with a series of fibers forming a flat structure on either side of the shaft.
3. The difference between feathers and down
Feathers are flat structures, their main function is for flight, and smaller feathers are for protection. Down is a three-dimensional structure, soft, fluffy, and mainly used for warmth.
4. Why is down so light, yet so well insulated?
Down is able to "swell" because of its three-dimensional structure. Each tuft of down filament holds more air for the same weight than any other man-made material. Each ounce of down has about 2 million filaments, which overlap and intertwine to form a protective layer that traps air to insulate and insulate.
5. How down and feathers are produced
Down and feathers are washed and dried in a special process, and then classified by blasting. After selecting the equipment, the best down floats to the highest box, the next to the middle box, and the feathers, because they are heavier, fall into the bottom box. The entire process must be performed correctly to remove odors
And to ensure the permanent fluffy down.
6. Which bird produces the best down?
Overall, the best down always comes from larger, more mature birds. Compared with mature birds of the same age, goose down is better than duck down. However, down from older ducks is better than down from younger geese. Larger downs have a very high insulation-to-weight ratio. A duvet or down sleeping bag using this down will be very light and very warm. And, they can be used for decades.
On the other hand, lower quality white goose down contains smaller down. It's not fluffy and has a low heat retention-to-weight ratio. Even with more weight of fleece, it can't be as warm as the former. Down from smaller birds not only have low bulk, but they "collapse" in a relatively short period of time. Because their fibers are too brittle. This is also often the difference between expensive and cheap goose down.
7. What is eider down?
Eider down is produced from eider ducks and is considered by some to have the highest quality down. Likewise, it is also the most expensive. The special thing about this fleece is that it clings to the eider duck for extra warmth. The eider is a protected migratory bird whose down can only be collected by hand from the nest without disturbing the bird.
8. Does climate affect the quality of fleece?
The climate does not affect the quality of the fleece, but the quantity of fleece. Birds in colder regions grow more fleece to keep warm. The quality of the fleece itself is only related to the maturity of the bird.
9. Does the color have anything to do with the quality of the fleece?
not related. White fleece is more popular because it doesn't show any difference in light-colored materials. Again, the quality of the fleece itself is only related to the maturity of the bird. For example, the down of an eider duck is brown-black.
10. Down is produced there
Most of the down comes from the East, accounting for about 50% of the world's total supply. Many of these white goose downs range in quality from very good to very poor. Many high-quality downs come from Europe.
