From the point of view of warm-keeping effect, the warm-keeping effect of white goose down jacket is better than that of white duck down, because the white goose down is bigger, fluffy and contains more gas, so the warm-keeping effect of white goose down jacket is better.
From the cashmere content, the cashmere content of white goose can reach 90 to 95, that is, the cashmere content in 100 weight unit is 90 to 95 units; The highest cashmere content of white duck down is 85 ~ 90, that is, the cashmere content in 100 weight unit is 85 ~ 90 units.
From the smell, white duck down comes from duck hair, ducks are omnivores, and there will be duck smell in the down. Although most of them can be eliminated after processing, down jackets filled with duck down will still come out after wearing for a year or two. White goose down has no fishy smell.
2 Is there a difference between white down and gray down? There is no difference.
The difference between white down and gray down lies in the different colors, but the warmth of down jacket has nothing to do with the color, but with the density of down internal structure and the fineness of down.
Only in practical application, gray down is mostly filled under dark fabric, and white down is filled under light fabric, so that the color of clothes will not be disturbed by the color of down. However, under the same cashmere content and filling amount, there is not much difference between them in comfort, warmth and fluffy.
Down jacket contains more than 70% cashmere.
Down content refers to the proportion of down in it, which is generally expressed as a percentage. Usually, the down jacket contains more than 70% cashmere, which is better. In this case, the down jacket and warmth are still good. After wearing it, it can resist several degrees of weather and meet the warm needs of most people.
4 The higher the cashmere content of down jackets, the better? Not necessarily.
According to the national regulations, the cashmere content of down jackets should not be less than 50%, and the allowable deviation of cashmere content is -5%, so many people think that the higher the cashmere content, the better, but this statement is not completely correct.
Because the cashmere content of ordinary down jackets is 70%-80%, it can meet the daily cold protection needs of most people. Excessive cashmere content will also lead to heavy weight of down jacket, which will be inconvenient for daily wear, especially for people who want light clothes, and the quality of down jacket depends on the cashmere content of down jacket and the quality of down itself. Cashmere content is not the only determinant.
