Abstract

A semipermeable membrane support comprising 10 to 70% by weight of polyester short fiber, 30 to 70% by weight of sheath-core composite fiber in which the melt point of the sheath part is lower than the melt point of the core part, and 3 to 40% by weight of polyolefin pulp fiber having a specific surface area 1-15m<SP>2</SP>/g, wherein, the polyester short fiber, the sheath-core composite fiber, and the polyolefin pulp fiber are formed into a non-woven structure. The semipermeable membrane support has an excellent strength and have MD/CD ratio between 1.0-1.5, which can be made of a single fiber layer by a wet process with a conventional paper machine, even a cylinder paper machine, without the restriction of using special sheet forming machine.
