Antivirus processing agent
COSMOTEX FPG-07
|
COSMOTEX FPG-07 is antiviral agent that is blended grapefruit's seeds extract and special organic compound.
For a cellulosic fiber, synthetic fibers such as the polyester, and a mixed spinning product, COSMOTEX FPG-07 gives the antivirus effect and antibacterial deodorization with the washing durability.
It shows durable superior performance by normal padding method and exhaustion method.
It is small amount, and an effect is provided.
There are not settle out, and uneven attached, during processing of products, because the product has good workability.
In October, 2020, confirmed an effect on SARS-CoV-2 newly.
SARS-CoV-2 is the disease-causing germ of the global new coronavirus infectious disease (COVID-19) that became prevalent in 2020.
