The difference between cotton jacket and down jacket which warm cotton jacket and down jacket

Which is the warmth of cotton jackets and down jackets? The difference between cotton jackets and down jackets, cotton jackets and down jackets are common clothes in winter, and the warmth is very good.
The average diameter of downed wool fibers is only about 5m. Due to the fineness of the feather fibers, it has high bulkiness and good warmth. The high and low air content of the down and fluffy makes the air layer heat conduction and convection effect in the down jacket much lower. The static air layer between the two layers in the clothing material will bring a good warmth effect, and the down jacket will keep warm. Performance is related to velvet and fabric.
The cotton fiber inside the cotton jacket can well prevent the air inside and outside the clothes from flowing, so that the heat in the cotton jacket can not be emitted, and the outside air can not enter, so that the heat preservation effect of the cotton jacket can be well achieved. The down jacket is directly filled with down, because it is fluffy and porous, so the gas content is much higher than the cotton clothing, and the gas permeability is also smaller, so that the air layer heat conduction and convection effect between the clothes are reduced a lot, the heat in the clothes is higher than the cotton clothes. More difficult to exude.
