< p > 3 kinds of silk were suspected of counterfeiting < /p >.

< p > the 40 consumers of silk products were purchased from Beijing Consumers Association from Wumart, WAL-MART, urban and rural warehouses, Zhuang Sheng Guang Guang, Changan shopping malls, Renaissance commercial city, Cui Wei building, Yansha outlets store, Bai Rong World Trade mall, Jingdong mall and shop No. 1 online supermarket. The prices range from two hundred or three hundred yuan to several thousand yuan.

< /p >

< p > by the China Federation of Commerce and industry needle and cotton commodity quality supervision and Testing Center (Tianjin), 40 kinds of silk were all up to standard in terms of formaldehyde, pH value, odor, decomposable carcinogenic aromatic amine dye and other safety indicators, but 19 kinds of quality indicators were not up to standard, accounting for 47.5%.

Luo Gang, director of the consumer guidance department of the municipal Consumers Association, pointed out that the information of the silk quilt was not accurately labeled, and the fiber content was not consistent with the actual measurement.

< /p >

< p > among them, 8 kinds of silk quilts were seriously missing, such as "Sheng Wei", the silk content was 51%, and the measured 20.8%.

The cotton content was 50% and 24.6%.

< /p >

< p > more, some enterprises counterfeit silk.

The "happy day" embossed silk quilt and "siled" pure silk quilt sold in Bai Rong World Trade mall are filled with 100% silk, and only a small amount of silk is found at the opening of the quilt, and other places are polyester or viscose fiber.

The "FASHION HOME" aristocratic silk quilt made by the authorized French Pierre Cardan company and the Shanghai Bolai home textile company was purchased from Suzhou Bridge store in the urban and rural supermarket. All the fillings were viscose and polyester fibers, and there was no silk at all.

< /p >

< p > problem < a href= "http://sjfzxm.com/news/index_c.asp > > silk < /a > has been much lower than" /p ".

< p > in addition to being inferior, there are 11 kinds of silk quilts which are not enough.

In the test, some silk was reduced by more than 1/3, and the weight errors of "red Fuji", "Hua NI SHI", "Providence Tianyi" and "Xi Lai Lai" were all very large.

< /p >

< p > City Consumer Association 19 said on the same day that the comparison test found that silk has been informed of the industry and commerce, the city's industrial and commercial departments have launched a law enforcement action on this basis, and the products with problems are temporarily under the rack to further investigate the situation.

The reporter learned that "silk flower", "Ai Wei home textile", "a href=" http://sjfzxm.com/news/index_h.asp "> Pierre cardan /a", "Hua NI SHI" and other silk have been off shelves and no longer sold.

< /p >

< p > Luo Gang, director of the consumer guidance department of the municipal Consumers Association, told reporters that the main reason for the poor quality of silk is that the production of raw materials by the silk is lower than the limit. The quality control is not in place. In order to obtain the inspection report to meet the needs of shopping malls, supermarkets and online shops, enterprises often send samples with better quality to the third party inspection, and artificially reduce the cost of subsequent batch products.

< /p >

< p > Experiment 1 < /p >

< p > silk goes out of flame, extinguishes < /p >.

< p > Objective: whether silk is filled with silk is pure.

< /p >

< p > experimental process: select some stuffing inside silk and put it on the alcohol lamp to burn. Only the filler on the left can burn, but the smoke is very small and has a burning smell. Once the flame is left, it will automatically extinguish. The right side of the filling will emit a black smoke, emitting a sweet smell, and it will continue to burn and flame after leaving the flame.

< /p >

Interpretation: < p > interpretation: Li Haolan, senior engineer of the China Merchants Association Quality Supervision and Testing Center (Tianjin), told reporters that from this experiment it can be seen that the real silk is extinguished from the left flame, and the thick black smoke on the right side is adulterated with polyester fiber.

When buying silk quilt, consumers can use this simple method to try true and false.

< /p >

< p > Experiment 2 < /p >

< p > true silk can be dissolved in alkaline solution < /p >.

< p > Objective: to test the fiber content of silk quilt < /p >.

< p > experimental process: the detection personnel were further identified by the reagent dissolution method.

Take about 1 grams of silk and fill it in the alkaline sodium hypochlorite solution of 1mol/l, stirring for about 1 minutes.

Soon, the liquid in the beaker on the left has become cloudy and the filling is completely dissolved.

There is not much change in the cup on the right, you can still see the filler itself.

< /p >

< p > interpretation: Wang Yang, deputy director of the testing room of the quality supervision and testing center of Tianjin cotton textile industry, said that silk belongs to animal fiber and can be dissolved by alkaline solution.

Consumers usually use 84 disinfectant (equivalent to alkaline solution) to replace this alkaline solution at home, and carry out small tests on their own.

< /p >

< p > Experiment 3 < /p >

< p > uneven thickness of silk under microscope. < /p >

< p > Objective: to see the shape of silk under microscope (< /p >).

< p > experimental process: the test personnel removed some samples from the silk quilt, then treated them and observed them under microscope.

< /p >

< p > interpretation: Wang Ji, deputy director of quality supervision, testing and testing center of Tianjin cotton textile industry, pointed out that silk under the microscope is glossy, irregular in shape and uneven in thickness.

If filled with polyester fibers, it can be shown with holes, very bright, with spots on the surface and very uniform thickness.

< /p >

< p > Experiment 4 < /p >

< p > 11 kinds of silk have a large deviation rate < /p >.

< p > Objective: to test the quality deviation rate of the silk quilt filling and see whether it matches the nominal weight.

< /p >

< p > experimental process: the inspector dismantled the silk quilt cover, took all the stuffing and weighed it on the balance, then put it in the oven for 3 hours, then weighed the dry weight, and calculated the quality of the moisture regain.

< /p >

< p > interpretation: Zhao Ying, a testing room of the quality supervision and testing center of Tianjin cotton textile products, said that the mass deviation rate of the filler determines the weight of the silk, and how much the weight affects the price.

The national standard GB/T24252-2009 "silk quilt" stipulates that the quality deviation rate of the filling products is superior to that of the first grade product, and the qualified value is (-2.0 to +10.0)%, and the qualified product is (-2.5 ~ +10.0)%.

But this experiment found that the quality deviation rate of 11 kinds of silk quilts was not up to standard, and some exceeded the standard seriously.

< /p >

< p > the "red Fuji" silk, known as Shanghai red Fuji Home Textile Co., Ltd., has the largest deviation rate of -36.4%, and the "Warren poem" silkworm quilt of Beijing Mariana Textile Co., Ltd. has a deviation rate of -35.5%.

< /p >

< p > purchase < /p >

< p > open the zipper to scrutinize the silk "deep" < /p >.

< p > according to the national standard, silk is the product containing 50% or more mulberry silk and / or tussah silk. Only 100% silk can be called pure silk quilt, and more than 50% of silk is mixed silk quilt.

< /p >

< p > City Consumers Association reminds consumers that silk is divided into two kinds: mulberry silk and tussah silk. Mulberry silk color is more white, softness and comfort are better.

And most of the tussah is wild, silkworm cocoon color close to green gray, through the bleaching of silk after a yellow color, the feeling is not as soft as mulberry silk.

Therefore, to purchase silk quilt, we need to check carefully whether mulberry silk or tussah silk is marked, the fiber content of filler, the quality of filler and the length of silk floss, which are directly related to the price level.

< /p >

< p > in addition, if conditions permit, try to open the zipper, buttons, etc. to check the quality of the filling, especially the quality of the silk quilt in the quilt, and select the silk quilt of mulberry silk, long silk or medium length silk. First, check whether the filling is uniform in appearance, uniform in color and thickness, no obvious hard, soft block and hard wire, no stain and no odor.

< /p >

< p > the length of silk silk is divided into long silk, long silk and short silk. The long silk is made from whole silkworm cocoons. < a href= "http://sjfzxm.com/news/index_h.asp" > natural silk > /a > cut off very little; medium length silk is more than 25 cm and above, short silk is mostly below 25 centimeters.
