Down is divided into goose down and duck down according to the type, plus the color and their mixture. The filling of duvet can be classified as follows: white goose down, gray goose down, white duck down, gray duck down, goose and duck mixed down and crushed down.
Goose down: Large velvet, small feather stalk, slender fiber, high bulkiness, good elasticity, and superior thermal performance.
Goose down is the flower-shaped fluff from the underarms and under the belly of a goose.
Goose down has good warmth retention and elasticity. The quilt made of goose down does not feel oppressive and stuffy. In addition, the goose down quilt also has the function of moisture absorption and perspiration, which can always create a dry and comfortable sleeping environment for you.
Goose down is a kind of animal protein, so the real goose down will have a slightly warm touch when touched by hand. In addition, goose down itself is a three-dimensional structure, fluffy and stretched in all directions, which can store a large amount of air, so the goose down quilt can effectively resist the invasion of external cold air and prevent the loss of the body's own temperature.
Duck down: The size of the down, the size of the feather stem, the length of the fiber, and the bulkiness are worse than that of the goose down, but the thermal performance is better.
However, if it is not handled properly, it is easy to smell.
Goose and duck mixed velvet: average velvet, poor elasticity, but good thermal performance.
Crushed velvet: processed and crushed from wool flakes, it has powder, poor elasticity and warmth retention, inferior quality, and easy to agglomerate after washing.
