The longer the duck (geese) breeding time, the longer the velvet grows: large velvet, more velvet, long velvet, more velvet ribs, and high fluffy. (Down with a bulkiness of 800 or more is generally selected by hand, so the price is very high, about 800-900 yuan/kg).

The larger the down feathers are, the more difficult it is to purify because the filaments are long and the feathers are tightly entangled with each other; the general processing factory can only extract the down to 86~88. And to refine to a higher down content (90~95 down), you need a very professional down manufacturer to do it.

The color of down

The velvet color of ducks (goose) raised for more than 60 days is very white, but there is no guarantee that 100% of them are pure white, and they contain about 0.1% black velvet. This is because white ducks (goose) that have been bred for a long time will grow different-colored down on their bodies, just as people grow white hair when they are older.

When people talk about goose feather, goose feather is indispensable. There is no 100% goose down, so goose down is necessary. Compared with duck feather, goose feather is tasteless and warm. Goose feather can be mixed with goose feather to fill your jacket, down pillow, down quilt, etc., or can be filled with Down cushion, down bed, down sofa, etc.

4-6cm white goose feather is widely used in different fields. It has the characteristics of large down, small feather handle, light weight, high filling force, tasteless, and high warmth retention.
