Is Pure Cotton 100% Cotton?

The sock expert's answer is no. If the composition of a pair of socks is 100% cotton, then this pair of socks is cotton. Generally, socks with a cotton content of more than 75% can be called 100% cotton socks. Generally, socks with a cotton content of 85% are very high-grade cotton socks. But the pure cotton fabric is not resistant to sunlight, easy to yellowing, poor elasticity, easy to wrinkle, mildew and deterioration, and low wear resistance. Therefore, cotton socks also need to add some functional fibers to maintain the elasticity, fastness and comfort of socks. (Spandex, nylon, acrylic, polyester, etc. are very common functional fibers. Socks without these functional fibers are not good socks.)
