Down warm principle
May 25, 2018

Down is a three-dimensional structure. Down jackets of good quality are generally very fluffy, so the same weight of down can fix more air than other materials. A large number of down filaments are intertwined to fix air and form a protective layer of heat insulation. In order to achieve a good thermal performance.

Feather clothing specified down fill nominal cashmere content can not be less than 50%, while the higher the amount of cashmere, the stronger the thermal performance. We can judge whether the quality is good or bad by observing the loftiness of the clothes in the daily purchase of down and winter clothes.

The down layers of birds are very plump. In the cold winter, they can be “naked” for the winter. They use feathers to keep the air stationary and keep their temperature isolated from the outside world.
