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.
Both have their own advantages. The style of the Safety Jacket is much more than that of the down jacket, and it is more fashionable. The down jacket is basically a single model.

Compared with man-made materials, the down warmth is three times that of ordinary man-made materials.In contrast, jackets are not as warm as down and are suitable for
Autumn and winter wear.
3, style: cotton aphid due to filling cotton, polyester fiber and other materials, the general style is slightly bloated. Down jackets are light, soft and warm. A down jacket made of Nisifang, with a total weight of 500-1000 grams, is 1/6 to 1/2 of the weight of other warm clothes. Because the down is soft, it is used as a clothing smear and is comfortable to wear.
4, practicality: cotton clothes will not be too troublesome in the daily wearing process, the process of down jacket is a bit troublesome, easy to run, the price of cashmere is also relatively high.
