China Feather And Down Industry Association: The Concept Of "Nano Velvet" In American State Has Been Questioned Or Harmful To Human Body.

< p style= "text-align: center" > img border= "0" alt= "align=" center "src=" /uploadimages/201312/07/20131207094609_sj.JPG "/" < < > >

< p > recently, Shanghai "a href=" http://sjfzxm.com/news/index_h.asp "Metersbonwe" /a "dress Limited by Share Ltd (hereinafter referred to as the United States of America) launched a" new calorie nano velvet "a href=" http://sjfzxm.com/news/index_h.asp "> cold proof clothing < /a > in the market. According to the media coverage, this new product of high-tech and fashion has adopted" environmental protection technology material "< a href=" http://sjfzxm.com/news/index_h.asp "> nanoscale coffee carbon fiber < < >", which can be heated up to 5 degrees above the traditional materials such as "general", "down", "ordinary cotton" and other traditional materials. This characteristic has attracted many consumers' favor.

< /p >

< p >, then, "is a href=" http://sjfzxm.com/news/index_h.asp "> nano velvet < /a", is it a high-tech material, is it better advertised as having better insulation effect? < a href= "http://sjfzxm.com/news/index_h.asp" > China down industry association < /a > said: This is doubtful.

Now let's take a look at the details of the world's clothing and shoe net.

< /p >

< p > < strong > label should not be so marked < /strong > /p.

< p > in order to find out, the reporter went to the Smith Baron store to find a "nano velvet" product. According to the product label content, the product name was classified as cotton clothing. The ingredients column was labeled as: "fabric: 100% nylon; lining: 100% polyester fiber; filler: Polyester fiber / heat storage, modified polyester fiber."

< /p >

Ye Hua, a href= "http://sjfzxm.com/news/index_h.asp", "Mei Bang" /a "brand center marketing department," an interview with reporters, said that "nano cashmere" products filled with "nano coffee carbon fiber" this environmental protection technology materials.

But reporters in the label and not only see this component, but is "polyester fiber / heat storage, modified polyester fiber" very eye-catching, so this so-called "heat storage, modification" is also what kind of material? According to sales personnel, I do not know, guess should be the nano coffee carbon fiber another name.

< /p >

Yao Xiaoman, director of the China feather and down industry association, told reporters that he never heard of the concept of "nanoscale coffee carbon fiber" and had never seen such a way of marking. P

< /p >

< p > according to Deng Jin, deputy director of the textile industry product testing center of Jiangsu inspection and Quarantine Bureau, from the label alone, the products of the United States do not meet the requirements of FZ/T 01053 "textile fiber content identification".

"Polyester fiber / regenerative, modified polyester fibers, heat storage and modification are not the name of the standard, according to the standard requirements are not allowed to mark this."

< /p >

< p > < < a href= > http://sjfzxm.com/news/index_h.asp > > textile fiber content > < /a > the fifth part of the national standard "fiber content and fiber name designation principle" stipulates that the name of the fiber should be used in the name of the specification and comply with the relevant national standards or industry standards. The name of natural fiber is specified in the name of GB/T11951, the name of down feather is adopted in the name specified in GB/T17685, the names of chemical fibers and other fibers are specified in GB/T4146 and ISO2076, and fibers with no uniform names in national standards or industrial standards can be labeled as "new (natural, regenerated, synthetic) fibers".

< /p >

< p > that is to say, throw away < < a href= > http://sjfzxm.com/news/index_h.asp > > modified polyester fiber > /a > whether it is "nanoscale coffee carbon fiber" and whether it has the effect of heat preservation.

< /p >

< p > < strong > is there any convincing power of test map < /strong > < /p >

< p > in the propaganda material of Smith Barney, there is a test map with instructions that "under the same time and heat source irradiation, it has the same degree of warmth as 90 feather, which is 5 degrees above the average temperature of other products".

The United States claims that the exclusive use of innovative coffee carbon nano energy layer, heat conduction technology to absorb external heat sources, instantly pformed into thermal energy into the body surface, rapid warming, continuous heat storage.

< /p >

< p > for this statement, Yao Xiaoman thinks that the test is full of loopholes in description.

First of all, the correct expression of "90 down" should be "feather down of 90%".

Secondly, according to the map, "nano velvet" did not continue to heat up, but showed a downward trend in about 8 minutes.

Thirdly, the experiment is inconsistent with the wearing rules of the winter clothing by the heat source, because the temperature of the outside body should be low when the body is wearing cold proof clothing. The experiment should test the effect of heat preservation rather than the warming effect.

< /p >

< p > finally, for the saying that "nanoscale coffee carbon heat storage fiber forms closed airbag, which can effectively lock heat", Yao said that this technology is mainly used in thermal insulation materials for space clothing, and the price is high. It is impossible to achieve a price of "399 yuan or 499 yuan" with nano velvet.

< /p >

< p > < < a href= > http://sjfzxm.com/news/index_h.asp > nano velvet > /a > has it been tested by the relevant departments of the state before its listing, and the characteristics of modified polyester fiber have been tested by the relevant departments of the state. When the reporter interviewed the United States, she was told that the "nano velvet" R & D institution was a commercial secret and would not reply.

Ye Hua told reporters that the United States has always focused on product quality and safety, and the products are strictly in accordance with national standards for production and testing. The products comply with the national basic safety technical specification for textile products, and will not cause harm to the human body.

< /p >

Yao Xiaoman did not get a clear answer to whether P questioned whether the US bond trial was accredited by professional institutions.

< /p >

< p > strong > nano filler is harmful to human body, /strong > /p >

< p > with the success of nanotechnology in the field of modern science and technology, many enterprises are more fond of this concept. So is the application of nanotechnology in the textile field appropriate? Because without clear response from the US state, experts can only guess through the knowledge they have acquired.

< /p >

< p > according to the experts of chemical fiber industry, the combination of nanoscale fiber materials and chemical fibers is not very close. It belongs to the combination of molecular level, and its fixation is very low.

If nanomaterials really use 0.3~0.5 micron (100 nanometer) nanopowder, then it will probably clog pores and cause harm to the human body.

"The lowest is redness, inflammation, itching. If it contains heavy metals, it will cause other harm to the body."

< /p >

The cost of < p > < a href= "http://sjfzxm.com/news/index_h.asp" > polyester fiber < /a > is 7 yuan per kilogram, and the price of "a" href= "http://sjfzxm.com/news/index_h.asp" with down down rate of 90% yuan is 450 yuan per kilogram.

Yao Xiaoman said, "nano velvet" is actually polyester fiber, merchants are just looking for a publicity gimmick, polyester fiber to "nano" and "velvet" rely on, but also directly compared with the down, the purpose is to steal the concept, add cheap "fluffy cotton" "technology, natural" concept, deceive consumers.

< /p >

< p > Yao Xiaoman thought that the United States did not publish the test results of the distinction between the characteristics of the modified polyester fiber and the traditional fluffy cotton in the authoritative department, and did not provide accurate product information to consumers, which made consumers ambiguous and misleading consumers.

< /p >

< p > < < a href= > http://sjfzxm.com/news/index_h.asp > nano velvet < /a > is technological innovation or gimmick innovation. All circles look forward to the positive response of the United States.
