How to Distinguish Whether It Is 100% Pure Cotton Fabric

Cotton is a pure natural fiber, soft and comfortable, with good moisture absorption and air permeability, and it does not irritate the skin and does not generate static electricity. It is not only a favorite clothing material for people, but also an inevitable choice for baby clothes (cute summer pajamas), men and women’s summer pajama sets, bathroom, bedding and also kinds of cotton fabric underwear. Especially in winter, it is very popular with the public.

 

Advantages: sweat-absorbing, breathable, soft, anti-allergic, easy to clean, and not easy to pill.

① Hygroscopicity: Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture into the surrounding atmosphere, and its moisture content is 8-10%. Therefore, when it touches human skin, it makes people feel soft and soft. Not stiff. If the humidity of the cotton cloth increases and the ambient temperature is high, all the moisture contained in the fiber will evaporate, so that the fabric maintains a water balance state and makes people feel comfortable.

② Moisture retention: Because cotton fiber is a poor conductor of heat and electricity, its thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between fibers, and air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good moisture retention, and wearing pure cotton clothing makes people feel warm.

③ Heat resistance: Pure cotton fabrics have good heat resistance. When the temperature is below 110°C, it will only cause the water on the fabric to evaporate and will not damage the fibers. Influence, thereby improving the washable and wearable performance of pure cotton fabrics.

④ Alkali resistance: Cotton fiber has a relatively high resistance to alkali. Cotton fiber will not be damaged in alkali solution. This property is beneficial to washing of pollution after consumption, disinfection and removal of impurities, and it can also be used for pure cotton textiles. Dyeing, printing and various processes are carried out to produce more new varieties of cotton weaving.

⑤ Hygiene: Cotton fiber is a natural fiber, its main component is cellulose, and there are a small amount of waxy substances, nitrogenous substances and pectin. Pure cotton fabric has been tested and practiced in many aspects, and the fabric has no irritation and no negative effect in contact with the skin. It is beneficial and harmless to the human body after long-term wear, and has good hygienic performance.

 

Disadvantages: easy to wrinkle, shrink, and deform.

 

① It is easy to wrinkle, and it is difficult to smooth out after wrinkling.

② It is easy to shrink. The shrinkage rate of pure cotton clothes is 2% to 5%, except for special processing or washing water treatment.

③ It is easy to deform and lacks elasticity. Pure cotton clothes are easy to deform, especially summer clothes, because the fabric is relatively thin.

④ Easy to stick hair, difficult to remove completely.

⑤ Acid-resistant, especially acid-resistant, when concentrated sulfuric acid stains the cotton cloth, the cotton cloth will be burnt into holes, and when acid (such as: vinegar) accidentally gets on the clothes, it should be cleaned in time to avoid fatal damage to the clothes caused by acetic acid.

 

Pure cotton woven fabric is a textile made of cotton as raw material, through the loom, the vertical and horizontal ups and downs of warp and weft yarns are interwoven.

Pure cotton fabrics are generally divided into:

①Natural white cloth: ordinary cloth, fine cloth, coarse cloth, canvas, twill gray cloth, natural color cloth.

 

② Colored cloth: There are vulcanized blue cloth, vulcanized ink cloth, Shihlin blue cloth, Shihlin gray cloth, colored poplin, various colors of khaki, and various colors of tweed.

 

③ Floral cloth: It is a cloth printed and dyed with various colors and patterns. Such as: plain printed cloth, printed twill, printed serge, printed Zhigong.

 

④ Yarn-dyed fabric: it is the yarn or thread dyed first, and then woven on the machine, such as plaid, sheet cloth, flannelette, thread cloth, decorative cloth, etc.

 

Now there are many kinds of fabrics. How to identify the texture of the fabric? This is not difficult, as long as you take a few yarns from the corner of the fabric and burn them, you can identify them.

1. There is a strong smell of burning hair, and the ashes are black and loose balls. They are pure wool or silk fabrics, while wool is short fiber and silk is long fiber, which can be distinguished from the shape.

2. There is a burning smell, and there is gray powder in the ashes, which is a wool-viscose blended fabric.

 

3. There is a burning smell, and the ashes are in a hard spherical shape, which is a blended or interwoven fabric of wool and synthetic fibers.

 

4. There is neither burning smell nor burning paper smell, but other special smells. The ashes are hard and spherical or lumpy, and they are pure synthetic fiber or blended fabrics.

 

Because the cost of high-quality pure cotton is higher than that of various man-made chemical fibers, some unscrupulous merchants will label "100% pure cotton" on low-grade blended or even all-chemical fiber textiles. Don't think that ordinary consumers can't do anything about "fake cotton", as long as a few simple tricks, "fake cotton" will immediately have nothing to hide.

 

The first trick: "Tathagata palm"

Pure cotton fabrics feel natural and soft, plump and thick, slightly astringent and muscular, and can be pulled in a small range, and the recovery speed after pulling is slow; while chemical fiber fabrics feel soft and slippery, with a large stretching range , it will spring back to its original shape as soon as you let go. 2. Knead the edge thread ends. After rubbing pure cotton, many thin thread ends will come out. You can see fibrous substances of different thicknesses. The chemical fiber structure 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 threads used for sewing are often cotton, which cannot be used as a reference for the difference.) In addition, because cotton yarns are tougher and weaker in elasticity, pure cotton clothes are easy to wear. The recovery time will be a little longer after wrinkling. I will teach you the most earthy and most recognizable method: you grab it, hold it in your hand, and then let go. If the wrinkle is severe, it means it is cotton, or there are many cotton components. . If there are few wrinkled marks, 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, it proves that the cotton content is higher, while pure fiber fabrics will not leave scratches.

 

The second trick: "Fiery 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 feels natural and there is little "reflection". When purchasing, you can flatten the clothes and add a certain tension. Then point the fabric and the body at a 45° angle downward to the light source. If there is a flash of light, then this must be a garment with high chemical fiber content. In addition, due to the addition of fluorescent whitening agents, chemical fiber white clothes will be whiter than pure cotton clothes, and may even feel dazzling. Of course, the easiest thing to do is to look at the washing water label on the clothes!

 

The third level: "a superficial touch"

As we all know, the water absorption of pure cotton fabrics is quite good. Soak the pure cotton clothes with some water, and then squeeze the water hard with your hands. If the water can't be squeezed dry, it proves that it is not pure cotton. If it is pure Cotton, after squeezing the water, it will show special wrinkles.

 

The fourth level: "Samadhi True Fire"

From a professional point of view, the best way is to use "Sanmai real fire" to refine it: pull out a small piece of yarn from the seam of the clothes to check it by fire. The real natural cotton fiber will not shrink when it burns. Instead, like paper, it will produce a natural yellow flame, and at the same time it will produce the smell of burning paper. After burning, it will produce greyish-white ash that can be crushed; while chemical fiber will melt and drip when it burns, and there will be black smoke and burning rubber smell. , Burning will form black hard spots. Of course, this inspection method is unsafe and unrealistic for ordinary consumers, so just make good use of your "Tathagata Palm" and "Golden Eye Fire Eye", and pay more attention to information about pure cotton and textiles With knowledge and knowledge, you can sharpen your eyes and choose real "100% cotton" clothing.

 

Pure cotton fabrics are favored by people because of their softness, breathability, and sweat absorption. Under normal circumstances, the market sales of natural fiber (cotton, wool, silk, hemp) products are often better than chemical fiber (polyester, nitrile, brocade, spandex, viscose, etc.) products. Some manufacturers and distributors fiddle with the content of ingredients in order to reap high profits. I can tell you responsibly that sometimes some underwear marked "100% cotton" actually contains less than 50% cotton. What's more, some clothes labeled as pure cotton are pure fiber at all. This situation not only exists in street fashion shops, but also in some brand stores. At the same time, there is no real pure cotton in all the clothes now, and "100% cotton" is the international common name.
