炭素短繊維不織布の製造方法
Document Type and Number:
Japanese Patent JP6603185
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a carbon short fiber nonwoven fabric containing regenerated carbon short fibers having excellent uniformity and excellent workability.SOLUTION: A method for producing a carbon short fiber nonwoven fabric is characterized in that: a slurry is obtained by dispersing regenerated carbon short fibers underwater with a high-speed-rotation shearing dispersing machine, and the slurry is used to produce a carbon short fiber nonwoven fabric by a wet paper-making method. More preferably, the high-speed-rotation shearing dispersing machine has a ring-like cutter having fine slits that rotate at high speed in part of the structure.SELECTED DRAWING: None
