Pure cotton fabric is very comfortable, but it is not easy to judge when buying. How should we buy pure cotton products in our daily life? Today I'd like to share three tips to keep you away from fake cotton products.
How can we tell if the fabric is pure cotton?
First move:
The pure cotton fabric feels natural and soft, feels plump and thick, slightly astringent and muscular. The pulling range is small, and the recovery speed is slow after pulling; The chemical fiber fabric feels soft and loose, has a smooth feeling, and has a large stretching range. Once you let go, it will bounce back to its original shape. In addition, due to the tenacity and weak elasticity of cotton yarn, the recovery time of pure cotton after folding will be slightly longer. When judging pure cotton, you can fold the fabric in half and scrape it along the edge with your fingernail. After unfolding, the more obvious the scratch is, which proves that the higher the cotton content is, while the pure chemical fiber fabric will not leave scratches.
Second move:
In addition to the mercerized cotton treated with caustic soda, the pure cotton fabric has no obvious luster, and the color is natural and soft. When it is put down naturally, it feels natural and has little 'reflection'. When purchasing, you can flatten the bedding and add a certain tension, and then face the fabric at a 45 angle downward with the body to the light source. If there is a bright light flashing, it must be a high content of chemical fiber. In addition, due to the addition of fluorescent whitening agent, the white of chemical fiber will be whiter than pure cotton, and even have a dazzling feeling.
Third level:
From a professional point of view, the best way is to use the "samadhi true fire" to refine it: take out a small yarn from the seam edge for fire detection. The real natural cotton fiber will not melt and shrink when burning, but will produce a natural yellow flame like paper, produce the smell of burning paper, and produce gray ash that can be crushed after burning; The chemical fiber will melt and drip when burning, and there is the smell of black smoke and burning glue. The burning will form black hard spots.
