US Courts Restrict The Use Of Nano Silver In Textiles

< p > recently, the a href= "http://www.91se91.com/news/index_p.asp" > US < /a > court heard the case of the US Natural Resources Defense Commission (NRDC) accusing the US Environmental Protection Agency of approving the use of antibacterial nano silver in textiles.

Finally, the court ruled that the US Environmental Protection Agency approved the improper conduct of the use of nano silver by US textile manufacturers, called for a reassessment and limited publicity to use antibacterial nano silver in clothing and other textiles.

< p > the case was originated in December 2011. The EPA approved HeiQ Materials to sell "a href=" http://www.91se91.com/news/index_c.asp "nano silver < /a" in the next 4 years and used for a href= "http://www.91se91.com/news/index_c.asp" > textile fabric < /a >, and requested the company to provide data on human health and aquatic life.

< p > although the EPD confirms that nano silver textiles are not risky for young children, the court found that the EPD approved the application despite the fact that its data showed potential danger.

"The decision of the court prompted us to move closer towards the goal of removing nano silver textiles," said the head of the P's health program.

The environmental protection department should not approve the use of nano silver because the technology has not passed the safety test completely.

The Committee hopes to limit the use of nano silver to ensure consumers' health.

< p > it is reported that nano silver has been pformed from metallic silver and has been promoted to be more powerful than silver, but it has ignored its potential threat to consumer health and has been widely used in fabrics, storage containers and other products.

< p > nano silver (Nano Silver) is the size of silver nanoparticles.

The size of nano silver is mostly about 25 nm, which has strong inhibition and killing effect on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae and Chlamydia trachomatis, and does not produce drug resistance.

Cotton socks made of nano silver and combed cotton fibers, such as 2XU antibacterial socks and AUN nano silver antibacterial and odor resistant socks, have good antibacterial and odorant effects.

< p > nano silver is a suspension consisting of silver and deionized water.

About 80% of the silver exists in the form of metallic silver nanoparticles, and the remaining silver exists in the form of silver ions.

Although the composition of nano silver is similar to colloidal particle silver, colloidal particles are generally suspended from particles of 10 to 1 microns in diameter, while the diameter of silver nanoparticles is less than 2 nanometers. Therefore, silver nanoparticles and colloidal particles are generally considered as different suspensions.

To be exact, nanoscale suspension is a more stable structure.

< p > washing in the short term does not affect its function; it has natural color and can be adjusted to color. After application, it does not affect dyeing. It can completely replace lead and tin solder. Long term use of nano silver will form silver deposition in organisms. It will have adverse effects on organisms, human body, too much deposition and even obvious poisoning. Nano silver will also have a certain impact on the environment. It will destroy the beneficial bacteria in the environment. After the nanomaterials are released, the bacteria will no longer have germicidal function. The time is usually three months to half a year, and long-term use will be harmful to the body, causing toxic symptoms and affecting body development.
