The difference between the two:
Acrylic cotton: polyacrylonitrile fiber, which is synthetic wool.
Widely used in civil fields, such as wool, blankets, knitted sportswear, tarpaulins, curtains, artificial fur, plush and so on. Acrylic fiber is also the raw material of carbon fiber, a high-tech product.
Down cotton: It is made of superfine fibers with different specifications through a special process and is called down cotton because of its quality like down.
Widely used in down jackets, ski shirts, winter clothes and other warm products.
Note: There is a similarity between them, that is, they are both industrial products, and they are widely used to make cold-proof products.
