摘要： The media comprises cellulosic fiber and silica based particulate or fiber filter elements and a charge modifying amount of a cationic charge modifying system bonded to the surfaces thereof. A component of the charge modifying system is a primary charge modifying agent characterized as a water soluble organic polymer capable of being adsorbed into the filter elements and having a molecular weight greater than about 1000. Each monomer of the polymer can have at least one epoxide group capable of bonding to the surface of the filter elements and at least one quaternary ammonium group. Preferably, the primary charge modifying agent is a polyamido-polyamine epichlorohydrin resin, a polyamine epichlorohydrin resin, or a resin based upon diallylnitrogen-containing materials reacted with epichlorohydrin. A portion of the epoxy groups on the organic polymer are bonded to the secondary charge modifying agent. This secondary charge modifying agent is an aliphatic polyamine having at least one primary amine or at least two secondary amines.

摘要： PURPOSE:To increase the specific surface area of paper while nearly maintaining the void volume and to make it possible to efficiently adsorb and capture fine carbon particles of submicron order formed in engine oil by fixing fine fibers on the surfaces of the constituent fibers of the paper. CONSTITUTION:Base paper composed of fibers of 10-80mu diameter is immersed in a dispersive medium contg. dispersed fine fibers 3 of 0.2-1mu diameter to stick the fine fibers 3 to the surfaces of the fibers 1 and the paper is dried. An adhesive is then impregnated to fix the stuck fine fibers 3 by 3-30wt.% of the amt. of the fibers 1. The specific surface area of the paper is increased while nearly maintaining the void volume at the constant volume and fine carbon particles of submicron order formed in engine oil are efficiently adsorbed and captured.

摘要： PURPOSE:To manufacture a filter paper which is small in pressure loss and inexpensive to manufacture and has a deodorizing function in addition to the conventional excellent dust collecting performance by mixing active carbon fiber, glass fiber and adhesive agent. CONSTITUTION:A filter paper is made by mixing active carbon fiber of 40-70wt.%, glass fiber of 20-40wt.% and adhesive agent of 1-4wt.%. The nominal specific surface area of the foregoing active carbon fiber is 700-2500m /g. As a result, a filter paper can be manufactured which, small in pressure loss and inexpensive to manufacture, features the deodorizing function in addition to the conventional excellent dust collecting performance.

摘要： PURPOSE: To provide a filtration fabric having high strength, uniformly distributed pores, low pressure drop and excellent filtration characteristics by bonding three components consisting of two kinds of fibers and a fibrous filler, having mutually dissimilar denier and length, with a suitable binder in an evenly intermingled state in a sheet. CONSTITUTION: The objective nonwoven filtration fabric is produced by suspending three fiber components consisting of two kinds of fibers and a fibrous filler in water to form a slurry, by feeding the slurry on the mesh of perforated forming wire to form a mat and impregnating it with a binder in an emulsion form, followed by heating the treated mat to dry it and to polymerize the binder. The first fiber component is staple polymer fibers(SF) of high denier and a certain fiber length, the second fiber component is staple polymer fibers of low denier and sorter length than the first fiber component, and the third fiber component is a fibrous filler (e.g. kraft pulp fibers) of shorter length than the first fiber component.
