1. It is enough to prepare a little water because if it is a pure cotton T-shirt, its water absorption is quite good. We dip a little water on the pure cotton T-shirt and then squeeze the water vigorously. If it is found If this T-shirt can be squeezed dry smoothly, it means that this T-shirt is pure cotton. On the contrary, if you can’t squeeze it dry, then this T-shirt is definitely not pure cotton! In addition, the top of the cotton T-shirt squeezed out of the water will look particularly wrinkled, which is normal!
2. The pure cotton fabric feels natural and soft, feels plump and thick, with a little astringency and bone texture, can be pulled less, and the recovery speed after pulling is slow; while the chemical fiber fabric feels soft, slippery, and stretched The amplitude is large, and it will spring back to its original shape as soon as you let go.
3. Knead the edge threads. After the pure cotton is rubbed, a lot of fine threads will come out. You can see fibrous materials of different thicknesses. The structure of chemical fibers is very uniform, and the thickness changes are not obvious.
4. Since the cotton yarn is relatively tough and elastic, the recovery time of pure cotton clothes will be slightly longer after wrinkles. I will teach you the most earthy and distinguishable method: grab it and hold it in your hand, and then let it go. The wrinkles are severe, which means it is cotton or cotton has a lot of ingredients. If there are few wrinkle marks, it means that other ingredients are mixed.
5. You can fold the fabric of the clothes in half, and then scrape it along the edge with your fingernail. After unfolding, the more obvious the scratch is, the higher the cotton content is, and the pure fiber fabric will not leave scratches.
