The editor teaches you how to distinguish between down and down cotton

2023/03/17

Down: Down is the feathers of birds, and down cotton is a cotton fiber product similar to feathers. Down is the fluff that grows on the abdomen of geese and ducks, and is called feathers in flakes. Because down is a kind of animal protein fiber, it has higher thermal insulation than cotton (vegetable cellulose), and the down ball-shaped fiber is densely covered with tens of thousands of small triangular pores, which can shrink and expand with temperature changes, resulting in a temperature-regulating function. Absorb the flowing hot air from the human body and isolate the invasion of cold air from the outside.

Down is divided into duck down and goose down, but duck down is common in the market.

Down cotton: It is made of microfibers of different specifications through a special process. Because the quality is similar to down, it is called down cotton, which fills the gap in the market for down substitutes. This product is light and thin, delicate to the touch, soft, good in heat preservation, not easy to deform, does not see through, has the feeling of down, and its heat preservation performance exceeds that of down of the same weight, and can be widely used in down jackets, ski jackets, cold-proof clothes, etc. Thermal products.

There are two types of down cotton: one is carded and formed, which feels similar to DuPont cotton, also known as imitation goose down cotton; the second is unformed, similar to PP cotton, which feels close to down and is an ideal substitute for down ! The so-called down cotton is actually hollow cotton, but it is not real cotton, but is filled with hollow polyester. Because the air is insulated, it has a certain degree of warmth.

In terms of comparing the two, the difference is obvious:

1. Down is a natural fiber, and down cotton (hollow cotton) is a chemical fiber;
2. The grade of down is higher, the quality is better, and of course the selling price is higher;
3. The thermal performance of down is better than that of down cotton.
