A nanofiber for a filter medium is provided that includes fiber-forming ingredients including polyacrylonitrile (PAN) and polyvinylidene fluoride (PVDF) and an emulsifying agent for improving the miscibility of the fiber-forming ingredients. The nanofiber has excellent mechanical strength and chemical resistance and, at the same time, significantly increased hydrophilicity without a separate surface modification/treatment to/on the nanofiber. A filter medium comprising said nanofiber can exhibit improved flux and filtration efficiency and excellent physical properties in a water treatment process in which a pressure equal to or more than a predetermined level is applied and which requires the filter medium to have high mechanical strength and in a water treatment process which requires chemical resistance as the liquid being filtered is strongly acidic or alkaline. Further, since the nanofiber has significantly superior spinnability, the mass productivity of the filter medium is significantly improved, and the unit costs of production can be reduced.

Disclosed are a sound absorbing fabric with improved thermal insulation, and a method of manufacturing the same, wherein an inorganic aerogel powder and a thermosetting binder resin are impregnated into a non-woven fabric made of a heat-resistant fiber, wherein the inorganic aerogel powder has a surface modified by a surfactant to be uniformly mixed with and dispersed in a binder resin, thereby forming the sufficient number of micro cavities inside the non-woven fabric and increasing dispersibility of the inorganic aerogel powder, and thus heat resistance, sound absorbing and sound insulating properties, and thermal insulation properties can be significantly improved.
