How to identify whether it is a cotton T-shirt

The first trick: “Tathagata Palm”
pure cotton fabric feels natural and soft, feels plump and thick, with a slight astringency and muscle and bone feeling, and the amplitude that can be pulled is small, and the recovery speed after pulling is slower; The chemical fiber fabric feels soft and loose, has a slippery feeling, has a large stretch amplitude, and will bounce back to its original shape when you let go. 2. Knead the edge threads, after the kneading of pure cotton, there will be a lot of fine threads, you can see the fibrous substances of different thicknesses, the organization of chemical fibers is very uniform, and the changes in thickness are not obvious. (But it should be noted that to choose the thread 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 relatively tough and weak, the recovery time of pure cotton clothes will be slightly longer after making wrinkles, teach you the most earthy and most distinguishable method: you grab it and hold it in your hand, and then let go, if it is very wrinkled, it means that it is cotton, or there are many cotton components. If there are few marks on the wrinkles, it means that other ingredients are mixed.
You can also fold the fabric of the clothes in half, and then scrape it along the edge with your fingernail, and after unfolding, the more obvious the scratch, the higher the cotton content, while the fabric of pure chemical fiber will not leave scratches.
The second trick: “Fire eyes”
In addition to the caustic soda treated mercerized cotton, the pure cotton fabric has no obvious luster, the color is natural and soft, when the clothes are put down naturally, the drape is natural, there is little “reflective” phenomenon, when purchasing, you can flatten the clothes and add a certain tension, and then the fabric and the body are at a 45 angle down to the light source, if there is a bright light flashing, then this must be a high-content chemical fiber clothing. In addition, due to the addition of fluorescent brighteners, the white clothes of chemical fibers will be whiter than pure cotton clothes, and even have a dazzling feeling. Of course, the easiest thing is to look at the washing label of the clothes! (Of course, this is for brand clothing, don’t look at the general street stalls)
The third level: “Dragonfly Point Water”
As we all know, the water absorption of pure cotton fabric is quite good, dip the cotton clothes in some water, and then squeeze the water dry with your hands, if the water can never be squeezed dry, it proves that this is not pure cotton, if it is pure cotton, it will show special wrinkles after squeezing the water.
The fourth level: “Samadhi True Fire”
From a professional point of view, the best way is to use the “Samadhi True Fire” to refine it: pull out a small yarn from the seam of the clothes and inspect it with fire, the real natural cotton fiber will not melt when burned, but will produce a natural yellow flame like paper, and at the same time produce the smell of burning paper, and after burning out, it will produce gray-white ash that can be crushed; while chemical fibers melt and drip when burned, as well as black smoke and burning smell, and burning into black hard spots.
Of course, this inspection method is not safe and unrealistic for ordinary consumers, so as long as you make good use of your “Tathagata Palm” and “Golden Eye”, and pay more attention to the information and knowledge about pure cotton and textiles, you can polish your shrewd eyes and choose the real “100% cotton” clothing.
In fact, the easiest way is to look at the tags on the clothes, which have various logos of clothes, so don’t underestimate him.
