Description:
Cotton ≠ 100% cotton (Why "7 Day / Week socks" is not 100% cotton?)
Some customers ask, Why not to say that the whole cotton socks, why the package is 73% cotton it? 84 here to explain the problem.
Why cotton socks also mixed with the other ingredient? In fact, 100% cotton socks really do not exist, it is not practical. Think about it, 100% cotton, it is a mass of cotton ah, it is no flexibility, no color, and do not wear, will soon be milled hole.
Therefore, in the sock production process, the general content reached 60-70% of cotton, called "cotton" socks. The other 30% generally have polyester + spandex or nylon + spandex component. Polyurethane is one of a pair of socks worn out quickly when there is crossing a wire attached to those materials, the role of spandex is mainly used to wear socks to ensure degree. Lo socks mouth parts, and other places where the need for elastic reinforced polyester or nylon are generally formed by adding polyester or nylon socks and dress sense should feel much better. And the socks logo, design, etc. can not use cotton to weave, so what we call "cotton" socks that are in addition to the elastic fiber yarn other than cotton.
