Therefore, silk quilt should be a kind of "green" environmental protection quilt. Take it out and tell the customer whether it is true or not, and let the guests take it orally.

The chilly north wind is blowing closer and closer, and the silk quilt market in Hang Cheng is getting hotter and hotter. Throughout the major supermarkets, from the ultra-low price of 199 yuan to the high-end goods of 1000 yuan or even more than 2,000 yuan, the prices of all kinds of silk quilts are far from each other. What is the difference? The average salesperson can't explain it clearly. Many quilts are printed with the words "silk quilt" or "super silk quilt" and "first-class silk quilt", but quite a few of them do not indicate the specific variety of silk, and the content of silk is not clear. 100% natural silk introduced in the manual is not clearly marked as mulberry silk or tussah silk, so ordinary consumers can't tell whether these silk quilts are true or false.
Can you tell whether the silk quilt used at home is genuine or not? Do you know the tricks of the silk quilt market? Mr. Zhu, who once worked in a clothing enterprise in Hangzhou, said: "In fact, mixing other fibers is only the simplest way to fake silk; Nowadays, unscrupulous manufacturers have "invented" four major fraudulent means to obtain ill-gotten gains. After their elaborate silk quilts, ordinary consumers simply can't tell the difference between good and bad; Only by sending it to the technical inspection department can the defects be detected. From raw materials to processing to labeling, every link has been tampered with by manufacturers. " Then, let's take a look at the four dirty tricks of silk fraud disclosed by insiders.
Zhao Yin 1 tussah silk is mulberry silk.
The difference between mulberry silk and tussah silk
Mulberry silk is silk extracted from cocoon. This kind of silk is white with yellow, delicate and smooth, and has a faint odor of animal fibers. This silk quilt is especially soft and close to the skin; At the same time, there is also a disadvantage, that is, after a period of use, the gaps between silks are easy to tighten, which leads to the thinning of the quilt and the thermal insulation effect is not as good as before.
Tussah silk is mainly produced in northern China and is spun from tussah silk. Its original color was gray-black. Therefore, it is necessary to bleach with acid-base chemicals in the production process, which is harmful to human health. Tussah silk is connected in blocks, and the quilt is made of tussah silk. Its original structure is not easy to reorganize, and it can only be arranged slightly, so its internal structure is still irregular. In addition, there are a lot of sericin in tussah silk, which makes it feel rough, not smooth enough and dull. So many manufacturers will use chemical additives to degum tussah silk. In order to increase the gloss of silk, some manufacturers will smear industrial silicone oil or even lard on silk. These additives are obviously not good for the human body.
At present, the price of mulberry silk in the domestic market has been rising in recent years, and now the best price of mulberry silk has reached 250 yuan/Jin; The price of tussah silk is only 200 yuan/kg, and the poor tussah silk is only 150 yuan/kg. Since it is also raw silk, illegal manufacturers will of course use cheaper raw materials.
Therefore, it is difficult for unscrupulous manufacturers to distinguish tussah silk from mulberry silk. The most commonly used method is to lay the bottom with mulberry silk, then separate one layer of mulberry silk from another layer of tussah silk, and finally wrap the bread with mulberry silk. If 30% tussah silk is used for a 2 kg quilt, the cost can be reduced 140 yuan.
Of course, because tussah silk is relatively rigid, it can enhance the warmth of the quilt, so some enterprises actively use tussah silk and mulberry silk to make silk quilts, and clearly mark the content ratio of the two, which is also recognized in the industry.
Short silk pretends to be a filament.
High-quality cocoon, after boiling, makes sericin fully relaxed, and the only natural long fiber is made by skilled workers. The quilt made of this kind of fiber through special processing can keep its previous shape unchanged, and only needs moderate drying and folding preservation. However, only short silk can be produced with inferior cocoons and silk scraps. This silk quilt is easy to deform and needs to be renovated regularly. In addition, some short silk are made of shredded silk fabrics, and their warmth retention effect can't be compared with real silk. Short silk's raw materials are messy and the colors will be different; Therefore, in order to keep silk white, some bleaching agents are often added, which destroys the natural properties of silk fibers such as elasticity, toughness and ductility, and poses a certain threat to human health.
Zhao Yin 3 took chemical fiber "mixed goods"
With the development of industrial technology, the production technology of industrial enterprises has been able to produce chemical fibers similar to silk. This kind of fiber is comparable to silk in handle, color and softness, so it is often regarded as a "miscellaneous product" of silk quilt by manufacturers.
Moreover, the price of ordinary filament chemical fiber on the market is less than1.20 thousand yuan/ton, and the price of most high-grade chemical fiber is less than1.20 thousand yuan/ton; This is much lower than the price of silk, and of course it can also "effectively reduce costs".
There is also a method of doping fiber, that is, breaking the fiber material together with silk scraps and waste silk to make short silk.
Zhao Yin 4 was sold as silk.
The main body of silk quilt is silk, but it also has an important accessory, that is quilt cover. Layers of silk wrapped in quilt cover is the real finished product, so someone started the idea of quilt cover.
They marked on the label of the quilt: "Silk quilt, 2.5 kg"; But in fact, the net silk content in the quilt is only 2 kg, and the other 0.5 kg is the weight of the quilt cover. When consumers buy, they can't determine the true content of silk in the quilt; So the quilt cover can also be sold at the price of silk.
Why is the silk quilt on the market so miscellaneous? Is there an industry standard for silk quilts? See what the experts say:
The industry standard of silk quilt has not been fully implemented.
According to Gu Hongfeng, a senior engineer of the Textile and Clothing Quality Inspection Center of Hangzhou Institute of Quality and Technical Supervision and Inspection, there are actually industry standards for silk quilts, but this standard is not a national mandatory standard, but a national recommended standard, and it is not enforced. This standard was issued by the State Economic and Trade Commission in 2003 and is called silk quilt. And she herself is the drafter of industry standards. Now this standard has become the standard recognized by most domestic enterprises. But because the standard is recommended, it is not mandatory; Therefore, some enterprises have not fully implemented it.
It is understood that the standard stipulates that silk is divided into three grades, namely, super grade, first grade and second grade. Super grade products must use filaments, and must not contain whitening agent or obvious dust, with uniform appearance and color, and the fiber is 100% silk. First-class products must use filaments with the same appearance and color, and the fibers are 100% silk, etc. The requirements for the second-class products are low, and no odor is required; More than 70% of the fibers are silk. In addition, the standard also stipulates that goods must indicate the length and width of silk quilt, the net weight of quilt cover and filler fiber, fiber type (including long fiber and short fiber) and content.
