There are many types of duvets, including white goose down, gray goose down, white duck down, grey duck down, goose-duck mixed down, pressed down and so on. Among them, the best quality is goose down, which is large in quantity, small in feather stalk, good in quality, elastic enough, strong in warmth retention, better in moisture absorption and perspiration, drier and more fluffy. Goose down refers to the down used as a filler in cold-proof products, taking flower-shaped down from the armpit and abdomen of geese. Goose down not only has good warmth and softness, but also has the function of moisture absorption and perspiration. Goose down is a kind of animal protein, which has higher warmth retention ability than cotton and other plant fibers. The three-dimensional triangular skeleton structure of down itself can store a lot of air, and air itself is a bad conductor, so it can resist the cold outside and the loss of its body temperature.
