01Advantages of JNC Filter

What sets JNC Filter apart is the ability to provide products with stable and highly reliable quality and excellent function, thanks to a system where all processes from raw material procurement to filter formation can be completed within the JNC Group.Liquid filters are used in a wide range of fields, including the chemical industry, electronics and semiconductors, foods, medical care, and cosmetics. They work behind the scenes to support a wide range of products and technologies.


02Advantages of Our Products

The special bicomponent fibers used as JNC Filter’s materials have a core-sheath structure consisting of a polymer with a high melting point as a core and coated with a polymer with a low melting point.Therefore, when manufacturing non-woven cloth at a temperature between the melting points of the two materials, the molten coating polymer adheres the fibers to each other while maintaining the three-dimensional structure of the core polymer.Then, cooling is used to create a strong network structure that maintains the three-dimensional structure.
