Goose down and duck down are difficult to distinguish with the naked eye. The staff engaged in textile testing said that in their previous testing of down products, the main problems were that some manufacturers used inferior raw materials to pretend to be down raw materials, the marked down filling amount did not match the actual, and the down fluffy degree Unqualified, unqualified down cleanliness, etc. Among them, the use of duck down to mix in goose down products often occurs.
According to reports, the inspection of feather and down is based on the "Down and Feather Standard Sample (Sample Photo)" issued by the National Standards Committee in 2010, which is exactly the matching of the "Down and Feather" standard.
"Standard Samples of Down and Feather (Sample Photo)" puts forward a detailed basis for the sensory detection of feather and down, especially for the identification of duck down. Arranged at the end of the branchlets, the distance between the ribs is short, about the length of the ribs. One is duck feather and the other is goose feather, which is slightly more expensive.
Goose down is definitely better than duck down, but duck down is more common. In terms of thermal insulation, goose down must be warmer than duck down. Goose down has large buds, small feather stalks, good quality, full elasticity, strong warmth retention, better moisture absorption, perspiration, dryness, and higher bulkiness.
Because the principle of keeping warm mainly depends on the amount of fixed air, that is, the more fluffy something is, the more air it can hold, the warmer it will be. The size of the down fibers is directly related to the amount of fixed air, so the best down always comes from larger and more mature birds.
The volume of goose down fiber is larger than that of duck down fiber, and the fixed air volume is also larger than that of duck down fiber, so it is naturally warmer than duck down. If it is filled with 100% down jacket, the 70% down refers to the down that is the down near the root of the feather. It's feathers with hard stems.
Down is divided into duck down and goose down. Under the same conditions, goose down is slightly warmer than duck down. Down has three main performance indicators: the first indicator is the filling weight, such as 400 grams of goose down to sleep. The 70% down inside refers to the down that is the down near the root of the feather, and the feather is the feather with a hard stem, so it is naturally warmer than duck down.
Ducks are cheap, geese are expensive. The taste of duck is particularly bad. Goose is not as common as duck. Duck has any color and is more mixed. The goose is white, healthy and the color is positive. Duck feathers are not as soft as goose feathers, goose feathers are light, warm and comfortable to cover.
