Feather clothing, also called shroud, was made by China Zhou instead of the feathers of birds and animals. Yak hair was used to make wadding in Han Dynasty, and goose feather was used to make wadding in Tang Dynasty. China down jacket became popular in the early 1980s. At that time, the fabric grade and processing level were not high, the style was monotonous, the cashmere content was low, the filling amount was large, and the appearance was bloated, so it was called bread clothing. With the progress of science and technology, down jacket has become an important part of the clothing field and an indispensable daily necessities for consumers in winter.
