Abstract: A filter medium is provided. The filter medium according to an embodiment of the present invention comprises a second support body and a nanofiber web layer which are sequentially stacked on each of both surfaces of a first support body, and is a filter medium having a flow path through which a filtrate filtrated in the nanofiber web flows in the direction of the first support body, wherein the nanofiber web has a basis weight of 30 g/m2 or less, the first support body has a basis weight of 250 g/m2 or more, and a thickness of 90% or more of the total thickness of the filter media. Accordingly, even in a backwash process performed at high pressure, as the shape, structural deformation, and damage of the filter medium can be minimized, the use period can be extended. In addition, as the flow path is smoothly secured at high pressure applied at the time of filtration and/or backwashing, the filtration water is quickly discharged to the outside from the inside of the filter medium or the backwashing efficiency is very excellent, and accordingly it is possible to be applied in various ways in various water treatment fields.

Abstract: Provided is a flexible electromagnetic wave shielding material. An electromagnetic wave shielding material according to an embodiment of the present invention is implemented to include a conductive fiber web including a conductive composite fiber including a metal shell part covering an outside of a fiber part such that the conductive composite fiber forms multiple pores; and a first conductive component provided in at least some of the pores. The electromagnetic wave shielding material is so excellent in flexibility, elasticity, and creasing/recovery that the electromagnetic wave shielding material may be freely changed in shape, and can be brought in complete contact with a surface where the electromagnetic wave shielding material is intended to be disposed even if the surface has a curved shape such as an uneven portion or a stepped portion, thus exhibiting excellent electromagnetic wave shielding performance. Also, it is possible to prevent deterioration of the electromagnetic wave shielding performance even with various shape changes. Furthermore, even if parts are provided in a narrow area at a high density, the electromagnetic wave shielding material can be brought into complete contact with the mounted parts by overcoming a tight space between the parts and a stepped portion. Thus, the present invention can be easily employed for a light, thin, short, and small or flexible electronic device.

Abstract: Provided is yarn for a cell culture scaffold. The yarn for a cell culture scaffold according to an exemplary embodiment of the present invention includes slitting yarn produced by cutting a compressed nanofiber web to a predetermined width. Accordingly, by creating microenvironments suitable for migration, proliferation and differentiation of cells, cell viability may be enhanced and cells may be three-dimensionally proliferated. In addition, a scaffold according to the present invention has a mechanical strength sufficient for prevention of disruption of the scaffold which occurs during cell culture, such that cells may be stably proliferated. Further, the scaffold according to the present invention uses slitting yarn formed of the compressed nanofiber web, thereby having pores with various sizes, and therefore cell proliferation and cell viability may be enhanced by creation of an extracellular matrix-like environment.
