The first move: "Buddha Divine Palm"
The pure cotton fabric feels natural and soft, full and thick, slightly astringent and muscular, and can be pulled to a small extent, and the recovery speed is slow after pulling; The chemical fiber fabric feels soft and loose, slippery, and has a large stretching range. Once you release it, it will bounce back to its original shape. 2. Rub the edge thread. After pure cotton is rubbed, a lot of fine thread will come out. You can see the fibrous substances with different thickness. The chemical fiber tissue is very uniform, and the thickness change is not obvious. (However, it should be noted that the thread ends of the textiles on the clothes should be selected. The sewing thread is usually cotton and cannot be used as a reference for differentiation)
In addition, due to the tenacity and weak elasticity of cotton yarn, it will take a little longer for pure cotton clothes to recover from wrinkles. This is the most recognizable method: you can grasp them in your hand and then release them. If the wrinkles are severe, it means that they are cotton or have many components. If there are few wrinkles, it means that other ingredients are mixed.
You can also fold the clothing fabric in half, and then scrape it along the edge with your nails. After unfolding, the more obvious the scratches are, which proves that the cotton content is higher, while the pure chemical fiber fabric will not leave scratches.
The second move: "Fire Eyes and Golden Eyes"
Except for the mercerized cotton treated with caustic soda, the pure cotton fabric has no obvious luster, and the color is natural and soft. When the clothes are put down naturally, the drape feeling is natural, and there is little "reflection". When purchasing, you can flatten the clothes and add a certain amount of tension, and then make the fabric and the body face the light source at a downward angle of 45. If there is a flash of light, then this must be a clothing with high content of chemical fiber. In addition, due to the addition of fluorescent whitening agent, chemical fiber white clothes will be whiter than pure cotton clothes, and even have a harsh feeling. Of course, the simplest thing is to look at the washing water mark! (Of course, this one is for brand clothing, and you don't need to look at ordinary stalls.)
The third move: "Dragonfly Skimming the Water"
It is well known that the water absorption of pure cotton cloth is quite acceptable. Dip the pure cotton clothes with water, and then squeeze the water with your hands. If the water cannot be squeezed out all the time, it proves that it is not pure cotton. If it is pure cotton, it will show special wrinkles after squeezing the water.
The fourth pass: "Samadhi is really angry"
From a professional point of view, the best way is to use the "Samadhi fire" to refine: draw a small piece of yarn from the seam of the clothes for fire inspection. The real natural cotton fiber will not melt when burning, but will produce a natural yellow flame like paper, and produce the smell of burning paper. After burning, it will produce gray white ash that can be broken; The chemical fiber will melt and drip when burning, and there will be black smoke and burning glue smell. The burning will form black hard spots.
Of course, this inspection method is not safe and realistic for ordinary consumers, so as long as you make good use of your "Tathagata God Palm" and "Golden Eye Flame Eye", and pay more attention to the information and knowledge about pure cotton and textiles, you can polish your eyes and choose authentic "100% cotton" clothing.
