We have a lot of cotton fabrics on the market and they use pure cotton braids. In fact, they are not pure cotton. Many consumers are dazzled by slogans - so as to prevent them from deceiving consumers, and to make everyone love them. Cotton but I do not know how to identify the troubles of cotton to be solved ~ Xiao Bian today to everyone put together a very practical three strokes ~! Think of a practical partner to collect!
The first move: Tathagata
Pure cotton fabric feels natural and soft, and it feels plump and thick, with a slight sense of astringency and musculoskeletal sensation. It can be pulled in a smaller range, and recovery after pulling is slower. The chemical fiber fabric feels soft and loose, there is a sense of slippery, stretching a large extent, a loose hand will spring back to the original shape.
In addition, the cotton yarn is more tenacious and less elastic, so the recovery time will be slightly longer when the cotton fabric is wrinkled. When judging cotton, the clothing fabric can be folded in two, and then the nail can be scraped along the edge. After the expansion, the scratches are more obvious. , The higher the cotton content, the chemical fiber will not leave scratches.
The second measure: eyesight
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 the bedding is naturally put down, the drape is natural and there is little “reflective†phenomenon. When purchasing, the clothes can be leveled and a certain pulling force can be added. , And then the fabric and the body down 45 angles to the light source, if there is light flashes, then this must be a high content of chemical fiber bedding.
The third measure: Sancha really fire
From a professional point of view, the best way is to use the "three real fire" refining: a small root yarn from the bed of the bedding to check the fire, the real natural cotton fiber will not melt when burning, Instead, it produces a natural yellow flame like paper, and produces the odor of burning paper. When burned, it produces grayish white ash that can be crushed; while the chemical fiber melts and drips when it burns. It also has black smoke and a burning smell. Burning will form black hard spots.
Of course, this test method is not safe and unrealistic for the average consumer. Therefore, as long as you make good use of your “restful eyes†and “eyes of the eyeâ€, usually pay more attention to the knowledge of “Quality Microteachingâ€. You can polish your eyes and choose the real "100% cotton" clothing.
