Down jackets are an indispensable warm item in winter, and they are loved by people for their excellent thermal performance. So, what is the principle that makes a down jacket so warm?Next, let's unveil the mystery of down jacket warmth.
First of all, the warmth principle of the down jacket is based on the special structure of the down jacket. Down is the downing of a bird, and there are many tiny down tubes between the down, which are filled with accumulated gases. Gas is a good thermal insulation body, which can block the invasion of cold air from the outside and reduce heat transfer. Therefore, the down jacket forms a warm "air" through the gas stored in these tiny down tubes, which effectively blocks the contact between the cold air and the body, so as to achieve the effect of maintaining body temperature.
Secondly, most down jackets are goose down or duck down. The down of these poultry is soft, delicate, comfortable, and has high thermal properties. In particular, choose high-quality white goose down or white duck down, the down tube is long and thin, which stores more gas and has better thermal performance.
In addition, down jackets also have an important layer of warm material, that is, down dust. Down refers to the end of the down tube, which is covered with tiny feather fragments. These feather fragments have a good thermal insulation effect, which can further improve the warmth of the down jacket. In addition, the presence of lint can also increase the isolation space between the lint tubes and reduce heat conduction.
Of course, in addition to excellent thermal performance, down jackets also have good performance in style. Nowadays, down jackets are also popular for sale on e-commerce platforms, and many people choose to buy down jackets online through e-commerce. As a huge sales channel, e-commerce platforms not only provide consumers with more choices, but also relatively affordable. What's more worth mentioning is that customers who buy down jackets through e-commerce platforms can directly purchase production goods from the root manufacturers, avoiding intermediate links and ensuring the quality and cost performance of goods.
In short, down jackets have become the best-selling items in e-commerce by virtue of their unique warmth principle and the advantages of manufacturer supply. Whether it's in the cold winter or in the extreme cold outdoors, wearing a high-quality down jacket can not only effectively maintain body temperature, but also bring a warm and comfortable wearing experience.
