Why is combed cotton yarn softer than ordinary cotton yarn?

The first is because the cotton fiber of combed cotton yarn is longer. Cotton yarn is composed of cotton fibers. The quality of cotton determines the length of cotton fiber. Generally speaking, high-quality cotton can provide longer cotton fibers. So combed cotton yarns usually need better cotton to make, and their fiber length is twice that of ordinary cotton. In order to reduce costs, ordinary cotton yarns will contain more short cotton fibers, which are not easy to bend, so combed cotton yarns are softer.

Secondly, the combed cotton yarn has finer fibers. The fiber thickness of cotton is different, even on the same cotton. The combed cotton yarn has been combed many times, removing those thick cotton fibers, leaving only the fine enough. Those thicker fibers will not be wasted, but used to make ordinary veils or coarse cotton yarn, which may be used to make rope, canvas, etc. Therefore, the finer cotton fibers of combed cotton yarns are the reason why they are softer.

The reason why combed cotton yarn is softer than ordinary cotton is that combed cotton yarn is purer. After many times of finishing, the combed cotton yarn has almost no impurities, especially cotton seeds and cotton scraps. So combed cotton yarn is softer.

It is for these reasons that combed cotton yarn is softer than ordinary cotton yarn, it is more suitable for making high-quality underwear and socks. For the thigh high socks, combed cotton will help improve the quality of thigh high socks. Because the thigh high socks should cover the thighs, so a pair of soft, thick and warm thigh high socks is necessary.
