Title: A NONWOVEN WEB DESIGNED FOR USE AS A HOT COOKING OIL FILTER MEDIA
Abstract:
This invention relates to a nonwoven material which has excellent dimensional and thermal stability in a wide variety of hot liquids, specifically for use as hot oil filter media, containing at least a first cellulosic nonwoven web, characterized in that the cellulosic nonwoven web is made from essentially pure cellulose formed of essentially continuous filaments which are multibonded by merged filaments, hydrogen bonding and physical intermingling of the filaments. Further it relates to composite nonwoven materials, where at least one web is characterized by being essentially pure cellulose formed of essentially continuous filaments which are multibonded by merged filaments, hydrogen bonding and physical intermingling of the filaments. The individual layers may, or may not, be designed to have different pore size construction to impart specific filtration performance efficiencies. It also relates to the use of the inventive nonwoven material as a hot oil filtration media, or product as well as to using of the inventive nonwoven material for the manufacture of a hot oil filter media, or product.
