A stuffing structure, including a stuffing substrate and a carbon layer, is provided. The carbon layer is directly attached to a surface of the stuffing substrate. The carbon layer exhibits an irregular shape, and the carbon layer is configured to radiate infrared. A manufacturing method of the stuffing structure is also provided.

The present invention relates to a process for cleaning and/or washing down and/or feathers comprising: (a) mixing the down and/or feathers with a solution of an alkyl polyglucoside; (b) optionally adding simultaneously or sequentially a solution of a Group 4 metal salt to the mixture of (a); (c) removing excess liquid; and (d) optionally drying the down and/or feathers. Down and/or feathers prepared according to such a process are also disclosed. The invention additionally relates to a down and/or feather washing and/or cleaning composition for rendering the down and/or feathers hydrophobic comprising a solution of an alkyl polyglucoside, optionally a solution of a Group 4 metal salt, and a water-repellent treatment. The invention further relates to a kit for cleaning and/or washing down and/or feathers and rendering the down and/or feathers water repellent.
