White goose down:
The main source of raw materials is Anhui Province and Heilongjiang Anhui Province, Liaoning Province and other places in China. The feathers are large, white and have no peculiar smell. The average growth cycle is more than 8 months. Therefore, the down is more mature and higher quality, which can reach 0.1g and 120, with an average diameter of 4- 5 cm, fluffy up to 850in3/30g.
White duck down:

Although it is much smaller than the goose down, it is relatively uniform and has a high fluffy degree, which is normal. Fluffy up to 600in3/30g
Summary of down quality:
1. Velvet size
(1) The duck (goose) down that has been cultivated for more than one year is about 100 to 150 per 0.1 gram.
(2) The duck (goose) down that is cultivated for 6 to 8 months is about 200 to 230 per 0.1 gram.
(3) Each 0.1 g of duck (goose) down cultured for more than 60 days is about 320 to 360.
(4) The duck (goose) down cultured for more than 35 days is about 400 to 460 per 0.1 g.
(5) Duck (goose) down for about 28 days is about 550 to 620 per 0.1 gram.
(1) 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).
(2) 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.
3. the color of down
(1) 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.
