About Us

You-Yuan Technology CO., LTD. specializes in producing and selling nano-silver yarns products. We highly value the importance of being eco-friendly by using nano-silver as material to manufacture the best anti-bacterial products without harming the environment. We are also committed to promoting and selling nano-silver yarns products to the global market.

We produce nano-silver yarns by using the deposition technology. By nanonizing and evaporating silver in a vacuum, it increases the surface area and releases Ag+ ions, which is effective in being anti-bacterial, anti-mold and deodorizing.

1 Nanometer = 10 to the power of -9 (m)
1000 Nanometer = 1 Microns (10 to the power of -6)
The Nano-silver particles of our product is 15~20 nanometer.
And it exists in the silver atoms form, when it encounters negative charge of bacteria, the silver ions will be freed from silver atoms to disinfect.
Because it is in the form of silver atoms, its safety and stability is better improved.

-The Foundation Of Nano technology
The size of the nanostructures is about 1 to 100 nanometer which is among the size of molecular and sub-micron structures. With this size, many quantum effects and phenomena are more effective, thus, the nanostructures could produce new properties that are completely different from large-sized substances.
Except for the size, nanostructures also featured in ” High surface, volume ratio, the potential of high density accumulation, and Elasticity of structural combinations.



Nano-silver is recognized as the most efficient substance which can be used in sterilizing, antibacterial, and deodorant in the world.
According to the research data of experiments, Nano silver can significantly eliminate more than 650 kinds of harmful bacteria.
The silver material can dissociate silver ions (Ag+) with "positive charge" in air or water. Due to the reason that common bacteria such as Escherichia coli, Staphylococcus aureus, Chlamydia, Klebsiella pneumoniae, Candida albicans, Pseudomonas aeruginosa, Hemolytic streptococcus, Salmonella and other cell membranes are "negatively charged" which could easily attract silver with "positive charge" ion.
Silver ions can penetrate the cells easily and enter the bacteria and interact with the bacteria in the enzyme protein on the sulfhydryl (-SH), which result in the enzyme protein to solidify and lose its activity. Thus, the DNA of bacterial’ syntheses could be destroyed and unable to divide and profiler, and then lead the cell to death.

-Regular Nano-silver products :
There are many Naon–silver products in the current market, but none of them using the vacuum bleaching, coating technology, or soaking silver ion. They share the same shortcomings - Persistence is not enough, the period of using is not long enough. Silver ion concentration is insufficient, the effecting of sterilize and antibacterial is not obvious.

- The Nano-silver products of You-Yuans：
We use [Vacuum steaming technology] to nanoize the Ag, and bring the Nano-silver particles to the plastic material, in order to produce sterilize, antibacterial proudcts. When the Nano silver particles becomes smaller, the substantial increase in the overall surface area would enlarge the activity. So it can release massive silver ions, significantly enhance the effecting of cleansing, antibacterial, anti-mildew, and deodorant.
In the humid environments or water, nano-silver will be released with a positive charge of silver ions: [active silver ions in the air] and [active silver ion aqueous solution]. We have the patent design of [nano-silver active silver ion antibacterial package], letting the silver ion released slowly, the unfinished part will be protected in the structure of the nano-silver’s filament. The concentration of silver and silver nano-silver antibacterial, antibacterial effect are not going to affected by losing silver ions in water - Persistent is very strong.
The products of our company use water as carrier, bring the silver ions out of Nano-silver, becoming the formation of antibacterial, antimicrobial silver ion solution. Only the Nano-silver would fade and become transparent when it is not effective – which can be use repeatedly.

Our series of products have TUV,SGS testing certification of Antibacterial and antimicrobial.
