Filler

The stuffing in down jackets, the most common are goose down and duck down, these two are divided into white and velvet. According to the price of the down jacket on the market, the order is: white goose down > gray goose down > white duck down > gray duck down. It may be affected by the order of the price, so many people think that the quality of the velvet is also sorted in this way, but it is not. Through the theoretical research and practical experience of down, in general, the same quality and cashmere of goose down is better than the warmth and fluffiness of duck down, but I think the color has little to do with the quality of down jacket.

As for why the white velvet is more expensive, I think the main reason is that the white velvet is better than the gray one, no matter whether it is light or dark, the gray velvet is more picky, only the down jacket can be placed. In dark fabrics. Considering the light color of white, the range of suitable fabrics is wider. The second reason: the reason for the fiber structure of white velvet. Its fibrous structure is relatively thin, soft, long, and long in fiber, which makes it more bulky and easier to keep warm.

Generally speaking, the larger and more mature poultry, the quality of the fluff is better, so the goose of the goose will be better. But the production process of goose down and duck down is the same, the difference between the two in quality, bulkiness and warmth is not much. The most important reason why goose down is more expensive than duck down, the author believes that the output of goose down is much lower than that of duck down - goose down can only produce one season a year, duck down can produce three seasons at most.

Down

The down jacket contains velvet and feathers.

The velvet is a hair that does not contain a feather stalk between the neck of the waterfowl such as a goose duck and the chest and abdomen. Because the hair of this part is often immersed in water, it has not only certain waterproofness, but also its ability to keep warm and cold. The best of the hair. In addition, because the fluff of this part has no feather stalk, it is very soft, the fiber is long and the bulkiness is high, and the folded volume is small, which is the best material for making down jacket.

The feathers in the down jacket refer to the hairs of other parts of the body in addition to the villi mentioned above, which are generally in the form of a sheet with a feathered stem in the middle. Feathers have a limited degree of warmth and no fluff.

Cashmere

The amount of cashmere refers to the percentage of fluff and fluff filled in this garment in the feather down of all fillers. For example, if you buy a down jacket with 90% white duck down and 10% white feathers, it means that the clothes have a cashmere content of 90%.

And when you decide to buy a down jacket, you must first look at the product label attached to the collar. If you have less than 50% of the cashmere, you should pay attention to it. It does not meet the minimum requirements of the national down garment. standard.

Volume of cashmere

Everyone must pay attention to the fact that the amount of velvet is not the same as the amount of cashmere. The amount of velvet is the percentage, and the amount of velvet is the mass of the actual feather + velvet that is charged, and the size of the clothes. , length, style and other factors.

The amount of cashmere that I just bought is called two or two, which is 100 grams. Some friends like to buy a large amount of cashmere when buying down jackets. I think this kind of thickness will be warmer, but you must not look down on the amount of cashmere, because the warmth of the velvet itself is very large, 80% of the cashmere is more than 75% warmer.

Fluffiness

Fluffiness is an important indicator of the degree of warmth in the world. It refers to the value of cubic inches of volume per ounce (30 grams) of down under certain conditions. For example, an ounce of down space for 600 cubic inches means that the down has a bulkiness of 600. In general, fat and mature birds have a high degree of fluffiness, and conversely, small birds have low loft.

But what is the use of fluffiness? There is a saying that the amount of cashmere represents the "quantity" of the cashmere, and the amount of cashmere determines the "quality" of the cashmere, and the bulkiness is also an important measure. In the case of a comparable amount of filling, the higher the number of hoods, the better the warming function. The higher the bulkiness, the more insulation air the down contains and the better the thermal insulation.

The down jacket of the general price, the fluffiness is about 450-500, and the down jacket with a slightly higher price can reach 600-900.

From the internationally better down jackets (many are designed for outdoor sports), the number of down jackets with high number of canopies is generally not high. Such specifications are generally used as the middle layer of the liner, which is convenient for outdoor sports. Compressed to carry. In outdoor sports, as warm-up outside, usually the amount of cashmere is high, and the number of canopies is low, between 650-750.

However, if it is used for our daily wear, I think that the number of canopies is enough at 450-500, and the amount of filling for a greater warming needs to be higher.
