Compositions and Characteristics of Down

The down product is composed of various elements such as down hair and feather, cloth, and residue master. The quality of the down product may depend on the quality and filling rate of the down hair and feather themselves, as well as other components.

DOWN CLUSTER

It is the hair generated by densely forming on the skin after feathers are generated in aquatic birds’ chests or bases, and has better quality than feather. It has a shape in which soft barbs spread in all directions centering on a single quill point.

DOWN FIBER

It refers to barbs of a single strand separated from the soft down and does not have a warming effect, and is not included in the soft down in the classification of the composition.

FEATHER

It refers to the hair on the surface that forms the appearance of a bird. The structure of the feather consists of rough, thick quill shaft, and hard branches grown on the shaft. Small feathers (less than 6 cm) are collected from the wings, neck, and chest of aquatic birds originating in Asia, Europe, and the United States. Large feathers (more than 6 cm) are not suitable as a filling material for textile products, so they are used for decoration or get crushed and used for livestock feed.

FEATHER FIBER

It refers to a stiff strand of barb that has completely fallen off the feather's quill shaft.

DAMAGED FEATHER

It refers to the hair collected from aquatic birds damaged by insects or worms or in poor health. The International Down and Feather Bureau (IDFB) categorizes as Slightly Damaged Feather when damaged by less than 25% of the total area of the feather, and Damaged Feather when damaged by more than 25%.

RESIDUE MASTER

It refers to a foreign substance contained in the wool that is created during the breeding and collection process, such as sand, scales, and skin. The powder scattering phenomenon that occurs when down is injected into a machine is classified into dust contained in residue master.
