What is cotton yarn-dyed brushed?
It is a kind of fabric with excellent warmth retention and comfort. It uses pure cotton fiber as raw material. The steel needle rubs the cotton fibers on the surface of the cotton yarn to form a layer of fine and soft fluff covering without revealing the weave pattern, which makes the contact with the skin more appropriate and natural, bringing a delicate feeling almost like cashmere.
