Abstract: An oil/water separating material having oil/water separating characteristics by using plasma surface treatment is provided, and an oil/water separating filter comprising the oil/water separating material is provided. An oil/water separating material comprises a hydrophobic plasma coating layer with a surface tension of 3.0x10^-2 J/M^2 to 7.2x10^-2 J/M^2 formed on a surface of a nonwoven fabric comprising a polymer fiber. The hydrophobic plasma coating layer is formed by performing a vapor phase deposition process of a mixed gas comprising a fluorocarbon gas with 1 to 3 carbon atoms and a hydrocarbon gas with 1 to 3 carbon atoms at a volume ratio of 50:50 to 90:10. The polymer fiber is at least one selected from the group consisting of a polyamide fiber and a polyester fiber. The polymer fiber has an average diameter of 1 to 10 mum. The nonwoven fabric is a single or composite nonwoven fabric which comprises a staple fiber, and is manufactured by a needle punching process, a hot junction process, a hot air junction process, and a hydroentanglement process, or a direct spinning process such as a spunbond process, a melt blown process, or a flash spinning process. Further, a contacting angle of the oil/water separating material and water is 120° or more.

Abstract: PURPOSE: A dust collection filter for filtering fine dust is provided which not only effectively removes fine dust but also maintains a high air-permeability and a low differential pressure by controlling size and stability of foam coated on the filter, and a method for manufacturing the dust collection filter for filtering fine dust is provided. CONSTITUTION: The method for manufacturing the dust collection filter for filtering fine dust comprises a resin foam preparation step of generating resin foam by blowing air into the emulsion solution after injecting an emulsion solution into a foam generator; a resin foam coating step of coating the foam on the non-woven fabric so that the foam state is maintained on the surface of an ordinary non-woven fabric after supplying the resin foam obtained from the foam preparation step to a foam coater; and a heat treatment step of drying the non-woven fabric by heating the foam coated non-woven fabric so that a temperature of the heated foam coated non-woven fabric is increased step by step in the temperature range of 90 to 170 deg.C.
