Pure cotton socks, that is, 100% cotton
Originally, there was no pure cotton in socks, and the cotton content was 60% to 85%. Because socks need to be elastic, and pure cotton has poor elasticity, it is impossible to use pure cotton as socks.
So we can only say that it is cotton socks, not pure cotton socks.
Pure cotton fabric: cotton as raw material, through the loom, the warp and weft yarns are interwoven vertically and horizontally. Now, according to the actual cotton source, it is divided into virgin cotton fabric and recycled cotton fabric.
The following two ways to distinguish whether it is pure cotton socks:
Pinch: There are obvious folds after pinching the pure cotton socks. Fold the fabric in half and scrape it with your fingernails. After unfolding, there is a clear crease line, while the chemical fiber fabric has no folds after pinching.
Burning: The cotton fiber does not melt or shrink when it is close to the flame. It burns immediately when it touches the fire. When it burns, it smells of burning paper.
