Paper comprising aromatic polyester and process for producing the same

摘要

A paper comprises 5 to 100% by weight of a thermotropic aromatic polyester pulp with constituting fibers having an average fiber diameter of at least 0.1 mu m and less than 10 mu m and substantially no branches, and is obtained by a process which comprises wet forming a paper material comprising 5 to 100% by weight of the above pulp which is obtained from sea-islands fibers comprising an islands component of the thermotropic aromatic polyester and a sea component of another polymer by dissolving or decomposing off the sea component before or after cutting the fibers to an average length of not more than 5 mm. The paper has excellent strength, texture, electric insulation property and like properties.
