What is the difference between "down cotton" and "down"?
Down cotton is different in the market, and some people call it cotton pure bio-wool. There is also a bio-synthetic velvet on the market, which is half-feathered half cotton, which is easily confused with real cotton (down cotton). Some black heart processing factories will use this stuffed material to deceive consumers, and it is still very common in the market. It is basically difficult to distinguish as a layman, and many people buy the wrong one.
Then down is the general animal feather plus a velvet, and the more velvet, the higher the quality of your down jacket, which is the amount of cash that we usually say on the tag. Usually 80% to 90%, it is good.
The difference between down cotton and down:
Down cotton is what we call silk, but not everyone thinks cotton, artificial products are cotton chemical fiber, down is animal feathers, mostly duck down and goose down, generally goose down is much more expensive.
Because down is the feather of the animal, and the density is better than the down cotton, and the insulation is higher, the down jacket is warmer than the average cotton suit.
The down is warm, and the bulkiness is high, the compressibility and resilience are stronger, and the general down cotton fluff is not so high, so the relative warmth is not so high.
