Title:
極細短繊維、複合体及び極細短繊維の製造方法
Document Type and Number:
Japanese Patent JP7296771
Kind Code:
B2
Abstract:
To provide extra-short fiber having cation exchangeability, a composite body obtained by compounding the extra-fine short fiber, and a method for producing the extra-fine short fiber.SOLUTION: The extra-fine short fiber comprises a resin including a functional group having cation exchangeability in the repeating unit of the resin, thus has cation exchangeability. Further, the extra-fine short fiber has a small average fiber size of 3 μm or lower and a small aspect ratio of 200 or lower, and has excellent dispersibility, thus is suitable for being added to a resin composition and preparing a composite body. The extra-fine short fiber can be produced by dissolving a resin including a functional group having a cation exchangeability in the repeating unit of the resin into a solvent to prepare a spinning solution, collecting the fiber spun using the spinning solution to form a fiber sheet, and pulverizing the fiber sheet.SELECTED DRAWING: None
