The down quilt is also called down quilt, and the filling is mainly down, which grows in the abdomen of geese and ducks and turns into reed-flower-like fluff and flake-like feathers. As down is an animal protein fiber, it has higher thermal insulation performance than cotton (plant cellulose).

Because wool and feather refer to a single filament falling from a whole feather or wool piece, respectively. Some so-called 100% feather "silk" duvets in the market are actually filled with broken wool and feather components in crushed feathers, which are low in price and have no warmth, or some so-called feather plush bedding is actually filled with "polyester fiber".

Although there is only one word difference between the product names of duvet and duvet, the filler content is quite different, and the price and cost are far apart, which is easy to confuse consumers, so pay special attention when purchasing. ?

Extended data:

Feather velvet quilt features:

1, the fine fiber layer can lock the air and produce a stable static air layer, which plays a role in keeping warm and cold.

2. Sufficient silica treatment and moderate curling make the fiber feel good, and the fiber will not entangle after long-term use, and still maintain excellent bulkiness. Its warmth and bulkiness can also be compared with natural down.

3. At the same time, the properties of its chemical fiber endow it with the advantages of no mildew, no mites, washability and easy storage.

4. The fine density of down fiber is a fraction of that of common four-hole and seven-hole fibers in the market, so the quilt fits well.
