Silk Quilt

The filling of the duvet is mainly down, which grows in the abdomen of geese and ducks, and forms reed flower-like fluff, which is called feathers. Because down is an animal protein fiber,it has higher heat retention than cotton (vegetable cellulose), and the down ball fiber is densely covered with tens of millions of triangular small pores,which can shrink and expand with the change of air temperature,produce atemperature regulation function,can absorb the hot air emitted by the human body,and isolate the invasion of cold air from the outside.
