At present, there are many varieties of silk on the market, and the price is different. From 100 yuan to 5,000 yuan, silk can be distinguished from price, label, workmanship, touch, appearance, fiber fineness, electrostatic reaction, combustion reaction and so on. Whether it is true or not.
1, look at the price
The price of silk quilt = silk raw material cost + tire cover cost + quilt cost + manual and packaging cost + manufacturer profit 1 kg silk (silk) = 3 kg dry 茧 = 6 kg fresh 茧, the annual price of cognac and fresh 都 can be Checked online. (Recommended price in China Silk Market). A pound of silk raw material is about 140 yuan to 2,000 yuan, a 200x230cm cotton quilt cover price is about 60~200 yuan; plus tire cover, quilt cover, packaging fee, manual fee, logistics fee, company profit, basically, low The quilt of 300 pounds is unlikely to be good. Of course, some manufacturers are not doing the activities of losing money at a loss, but if this manufacturer has been selling at the clearance price, I think it will basically not What is good?
In a word summary: silk is a relatively high-grade bedding, is a good good goods, good goods are not cheap, cheap and not good. Although the high price is not necessarily the real thing, the low price is definitely a fake.
2, look at the label, quilt cover, tire cover
A qualified silk quilt should have one or two labels, which will be detailed on the product name, product specifications, product weight, material composition (separate fabric and tire), product grade, etc. In addition, there should be product precautions on the label as well as the company's origin, company name, etc. If the product does not have a relevant label, it is likely to be a counterfeit product, and it is not recommended to buy it.
The quality of the quilt can be judged by the work of the quilt cover and the tire cover. If the work of the quilt cover and the cover is very delicate and humanized, then the quality of the quilt can be better. Once you have confirmed the grade of the filling, you can place an order.
3, look at the touch
Good silk is made of high-quality silk, smooth and elastic, smooth and non-caking, delicate and smooth. The silkworm silkworm cocoon is smooth and silky, but the gloss, elasticity, fineness and comfort are not as good as mulberry silk. The silk is rough, the hand feel is poor, and there are stolons and stalks.
4, look at the appearance
Pull the zipper opening at the edge of the quilt and try to take the silk in the middle of the tire. See if the color of the silk is bright and uniform without fluorescence reflection. Whether the silk is long and elastic.
If you find cotton wool, impurities, other chemical filaments or fluorescent reflection, please do not buy. Try to open the inspection port as much as possible to observe the larger area of ​​the fetus and avoid adulteration in the middle.
The high-quality silk has a pearl-like color and diffuse refraction of light. Clean and less contaminated, the silk road is orderly and neat, the silk is very thin, and has strong toughness; while the poor quality silk is often added with bleach and other chemicals, so that its appearance is pale, not shiny and moist. More impurities, silky roads, darker colors, yellowing.
5, see the length and fineness of silk fiber
Good silk is pulled by hand with high-quality silk, it is not easy to pull open, and the inferior silk will be pulled open by hand, and some will be bundled. The better the silk stretch, the better the quality. Studies have shown that the superior tensile strength of mulberry silk should be stronger than that of the same diameter; high-quality silk has excellent recovery elasticity; while the inferior silk has poor fiber strength and elastic properties.
Good silk is made of high-quality silk. No matter how you play or lick, it will not form a group. Inferior silk will be agglomerated by the ankle during sleep. Now many manufacturers only place some filaments in the quilt opening, and inside. All are short staples, so you can reach out to the depths of the opening and lick some of them out.
The length of tussah silk is generally less than 80 cm during the process of pulling, while the length of mulberry silk can reach more than 1000 meters, and the length of other chemical fibers is generally less than 100 cm.
The silk is thinner than the tussah silk. The thickness of the silk is generally only 1/10 of the hair, and the thickness of the silk is the same as that of the hair. When distinguishing the silk and the silk, you can also use the hair to compare.
6, see the electrostatic reaction
Looking at electrostatic reactions is an effective experimental method for identifying true and false silk quilts. Before you buy a silk quilt, you need to prepare a cardboard and some shredded paper scraps. And carry these items with you to the mall or specialty store. First choose your favorite brand, price, weight and color matching silk quilt. When you choose, let the shopping guide open the silk quilt cover to reveal the silk inside. Then with the permission of the salesperson, you rub the silk exposed at the pull and rub it for about a minute, then take out the cardboard and shredded paper you have prepared, at a distance of about 0.3 mm to 1 Within the distance of about millimeters, let the silk that has just been touched absorb the paper scraps. If the paper dust can be sucked up, it means that it is a chemical fiber or a large amount of chemical fiber, not pure silk. If you can't pick up the paper scraps, it's an authentic silk quilt. Pure silk does not produce an electrostatic reaction.
7, see 84 solution dissolution reaction
After the silk is put into the 84 disinfectant, the silk will be completely dissolved, while other ingredients can not! However, this method can only identify whether it is silk or not, whether it is mulberry silk or tussah silk.
Analysis of the cause: Silk is a natural animal protein that is resistant to acids and alkalis. Alkaline substances will dissolve when exposed. Therefore, after the silk is put into the 84 disinfectant, the silk will be completely dissolved. Kapok and chemical fiber are insoluble. In addition, the dissolution rate of mulberry silk is faster than that of silk.
8, look at the combustion reaction (Figure)
The burning point of silk is very low, it is extinguished very quickly after burning. The smoke emerging from burning is white, accompanied by the burnt smell of protein (like the burning smell of hair, feathers, etc.), after burning The ash is brittle and fragile, and the hand is pinched into powder; the chemical fiber material burns with black smoke and has a pungent odor, and the gray ash is black and agglomerated, and the hand is pinched, and there is a clear difference between the two.
In summary: after many aspects of price, label, workmanship, appearance, touch, electrostatic reaction, 84 solution dissolution, combustion, etc., in most cases, it can be distinguished whether it is real silk. As a personal product, silk is not recommended to buy small inferior goods. Don't let the "silk quilt" become a place to hide dirt, but to become a real practical quilt.
