Down (fine but siliceous fiber), named FEATHER FABRIC in English, also known as filamentary down and down silk, is a kind of superfine chemical fiber. It has excellent hand feel and warmth retention. Fiber is as soft and slender as natural eiderdown, with excellent hand feel and warmth retention. The fine fiber layer can lock the air and produce a stable static air layer, which plays a role in keeping warm and cold.

The fine density of down fiber is a fraction of the common four-hole and seven-hole equal-length fibers on the market. At present, the best superfine fiber in China is between 0.8-2.5d Down is softer, smoother and feels better because of its fine fineness and silicone oil.

The warmth and bulkiness of down can be as beautiful as natural down, and the properties of its chemical fiber endow it with the advantages of no mildew, no mites, easy storage and easy washing, which is especially suitable for people with down allergy.
