Title:
PRODUCTION OF METALLIC FIBER SINTERED SHEET
Document Type and Number:
Japanese Patent JP3742717
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a sheet composed of metallic fiber with a dense network structure having uniformity and optional fibrous diameter by producing a metallic fiber-blended sheet from slurry contg. metallic fiber, split fiber and a binder by a wet papering method, thermally decomposing and removing the slit fiber and the binder and thereafter sintering the space between the fibers at a temp. not exceeding the m.p. of the metallic fiber.
SOLUTION: As the split fiber used for the metallic fiber-blended sheet, particularly, the one composed of polypropylene and an ethylene-vinyl alcohol copolymer is suitable. In this way, excellent dispersibility can be obtd., the improvement of the strength of wet paper can be attained at the time of wet papering, and, furthermore, bating required for the preparation of slurry to form the raw material of paper is made needless. Moreover, the binder is thermally melted in the sheet in a drying stage at the time of wet papering, and, polyvinyl alcohol fiber is suitable because of being excellent in dispersibility into water, being good in mixability with the metallic fiber, being thermally melted relatively at a low temp. or the like.
