CYLINDRICAL DEPTH FILTER FOR FILTERING FLUID

摘要

PURPOSE: A cylindrical depth filter for filtering fluid is provided to prevent the escape of fiber from a non-woven filtering medium by using a core composed of bi-component composite fiber-based non-woven fabric. CONSTITUTION: A cylindrical depth filter for filtering fluid includes a cylindrical core and a laminate. The core is composed of bi-component composite fiber-based non-woven fabric and is positioned at the inner center of the filter. The laminate is formed on the core and is composed of a filtering medium. The filtering medium is composed of a support and a non-woven fabric filtering material. The bi-component composite fiber-based non-woven fabric is obtained by melt-spinning polypropylene and polyethylene. The support is composed of bi-component composite fiber-based non-woven fabric.
