What are the striking advantages of circular knitting interlining？

1. High strength: the strength in wet state is basically the same as that in dry state. Impact strength is 4 times higher than nylon[0.2秒] and 20 times higher than viscose fiber.

2. Good elasticity. Elasticity is similar to wool, wrinkle resistance are far more than other categories of fibers, good stability.

3. Good heat resistance, high temperature will not be deformed.

4. Corrosion resistance. Circular knitting interlining can resist bleach, oxidizer, hydrocarbons, ketones, petroleum products and inorganic acids.

5. Good wear resistance.

What is the safety of meltblown fabric for masks?

Meltblown nonwoven fabrics are considered safe for commercial manufacturing of masks. However, meltblown fabric also has a difference in quality. The more common meltblown technology used for masks is those with bacterial filtration efficiency greater than or equal to 95% and greater than or equal to 99%. The mask only cuts off the transmission carrier of viruses, such as droplets, saliva, aerosols, etc. As long as they meet both of these are masks are safe.
