The cotton fabric feels natural and soft, feels plump and thick, slightly astringent and muscular, can be pulled to a small extent, and the recovery speed after pulling is slower; The chemical fiber fabric feels soft and loose, has a slippery feeling, and has a large stretching range, and will spring back to its original shape as soon as it is released. Kneading the edge thread, after the kneading of pure cotton, a lot of fine thread will come out, you can see the fibrous substances of different thicknesses, the structure of the chemical fibers is very uniform, and the thickness change is not obvious. (However, it should be noted that to choose the thread end of the textile on the clothing, the thread used for sewing is often cotton, and cannot be used as a reference for distinction)

In addition, because cotton yarn is tougher and less elastic, the recovery time of cotton clothes will be slightly longer after making wrinkles, teaching you the most earthy and most discernible method: you grab it and grasp it in your hand, and then let go, if the wrinkle is very strong, it means that it is cotton, or there are many components of cotton. If there are few wrinkles, it means that other ingredients are adulterated. You can also fold the fabric of the garment in half, and then scrape it along the edge with your fingernails, after unfolding, the more obvious the scratch, the higher the cotton content, while the fabric of pure chemical fiber will not leave scratches.
