We all know that down is the feather of birds, and down cotton is a cotton fiber product similar to feathers. Do you know how to distinguish down from down cotton? Let's follow Xiaobian to learn about it.
down is the down that grows on the abdomen of geese and ducks, and is called feather in the shape of reed flowers. As down is an animal protein fiber, it has higher thermal insulation than cotton (plant cellulose), and thousands of triangular small pores are densely distributed on the down spherical fiber, which can shrink and expand with the change of temperature, produce the function of temperature regulation, absorb the flowing hot air emitted by the human body and isolate the invasion of external cold air. Down is divided into duck down and goose down, but duck down is common in the market.
down cotton: it is produced by different specifications of superfine fibers through special processes. It is called down cotton because it is similar to down, which fills the gap of down substitutes in the market. The product is light, delicate, soft, good heat preservation, not easy to deform, will not penetrate the silk, and has the feeling of down. Its thermal insulation performance exceeds the down of the same gram weight. It can be widely used in a variety of thermal products such as down jacket, ski jacket, cold jacket and so on. Down cotton is divided into two kinds: one is carding and forming, which feels similar to DuPont cotton, also known as imitation goose down cotton; The second is not shaped, similar to PP cotton, which feels close to down. It is an ideal substitute for down! The so-called down cotton is actually hollow cotton, but it is not real cotton, but hollow polyester as the filler. Because the air is insulated, it has certain warmth retention.
in terms of comparison, the difference is obvious:
⑴ down belongs to natural fiber and down cotton (hollow cotton) belongs to chemical fiber;
⑵ the grade of down is higher and the quality is better. Of course, the price is also higher;
⑶ the thermal insulation performance of down jacket is better than down cotton.
the above is about the identification method between down and down cotton. I hope Xiaobian's answer will be helpful to you. You can continue to pay attention to our website, and Xiaobian will continue to update more content for you.
