Down filler is a measure of down quality and down jacket filler weight. Under the condition of ensuring the "cashmere content", the "cashmere content" of down jackets for ordinary adults in the south should reach more than100g, and that of ordinary down jackets in North Korea should reach more than 200g, so that warm down jackets can play a better role.

According to China's down jacket standard, the down jacket contains no less than 50% cashmere, and the allowable deviation of down jacket content is -5%. According to different target designs, the filling amount of down jacket is about 100-450g.

Fill feature:

1, the filling structure of down determines the temperature and light characteristics of down jacket.

2. Feathers are not easily compacted by fibers, so when they are surrounded by fabrics, they will form a three-dimensional box structure and a small space with a double-layer sandwich structure, which is also commonly known as a filling structure.

3. For the three-dimensional box structure, its advantage lies in the uniform distribution of down and no cold bridges effect, but the manufacturing process is complicated and the weight of down jacket will be greatly increased; The advantage of double-layer clamping structure is that the clothes are light in weight, but they are easy to be short of cashmere at the sewing position and blown through by the wind, so they are generally used in down jackets.

4. The smaller the structural space of down jacket, the greater the down filling quantity and the more uniform the down distribution. However, various structures have certain advantages and disadvantages, so different structures are suitable for different down jackets.
