Method Of Testing True And False Cotton

Cotton is pure natural. fibre It is soft and comfortable. It has good moisture absorption and permeability. It does not irritate skin and can not generate static electricity. It is not only the clothing material that people like, but also the inevitable choice of baby clothes, bathroom and bedding. Especially in winter, it is very popular with the public. However, because the quality of pure cotton is higher than the cost of all kinds of man-made chemical fibers, some bad merchants will label the "100% cotton" on the low grade blended or even synthetic fiber fabrics. Do not think that ordinary consumers can not apply "fake cotton". As long as there are three simple measures, "fake cotton" has no escape.

　　 The first move: "Tathagata palm"

Pure cotton fabric feels natural and soft, feels rich and thick, with a slight sense of astringency and a sense of bones and bones. It can pull a smaller amplitude and slow recovery after pulling, but the chemical fabric feels soft and smooth, and has large slip.

In addition, because cotton yarn is more tough and less elastic, the recovery time of pure cotton clothes will be longer after wrinkles are made. When judging cotton, the fabric can be folded and then scratched along the edge. The more obvious the scratches, the higher the amount of cotton, and the fabric will not be scratched.

　　 The second recruit: "eye piercing eyes"

Except for the mercerized cotton treated with caustic soda, pure cotton fabric has no obvious luster and natural color. clothes When you drop down naturally, you will feel natural and seldom reflect the phenomenon. When you choose to buy, you can flatten your clothes and add some pulling force, and then put the fabric down to the light source in the 45 corners of your body. If there is a bright light, it must be a high content chemical fiber clothing. In addition, because of the addition of fluorescent whitening agents, the white fabric of chemical fiber will be more white than that of pure cotton and even have a glare.

　　 Third pass: "true fire of samadhi"

From a professional point of view, the best way is to use "Sammy real fire" to make one refining: extract One Sa from the edge of the clothes and carry out fire tests on it, and make use of the pure cotton fabric for spring leisure wear, suit, school uniform, tooling, professional wear and trousers. In the recent textile market, most of the textiles used in the production of uniforms, uniforms and sportswear in the light textile city occupy a majority of the share of dyeing cotton varieties. The real natural cotton fibers do not shrink when they burn. Instead, they produce natural yellow flames like paper and produce the smell of burning paper. After burning, they produce grayish white ashes which can be rubbed; while chemical fibers will melt and drip when burning, and smoke and fuel smell will also form black spots.

Of course, this test method is not safe or realistic for the general consumers. Therefore, the high Zhou Bo electron tube (oscillating tube), high Zhou Bo resistance, high Zhou Bo capacitance, positioning pin (copper nail) and related machine and mold fittings, high Zhou Bo plastic welding machine, heat sealing machine, leather embossing machine, high vacuum suction machine for light packaging, high Zhou Bo suction machine high Zhou Bo machine. As long as you have good use of your "Tathagata" and "golden eye", support any color, and define the carving order, you can easily achieve all or one-time output. Pay more attention to it in peacetime. Pure cotton And textile information and knowledge will be able to polish the eyes and select the real "100% pure cotton" costumes.
