Title:
REGENERATED CELLULOSIC FIBER, METHOD FOR PRODUCING THE SAME, AND FIBER STRUCTURE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2021070887
Kind Code:
A
Abstract:
To provide a regenerated cellulosic fiber improved in an adsorptivity onto an object to be removed, a functional agent and the like and a carrying property of a functional agent and the like onto a fiber without causing inconvenience on a process due to falling of fine particles, a method for producing the same, and a fiber structure including the same.SOLUTION: In the regenerated cellulosic fiber related to the present invention, stripy recessed parts linearly extending in a fiber axis direction and holes having a major diameter smaller than a length of the stripy recessed parts in the fiber axis direction are formed on a fiber surface, and the stripy recessed parts include a length of 15.0 μm or more in the fiber axis direction. The present invention further relates to a method for producing the regenerated cellulosic fiber in which a fiber surface of the regenerated cellulosic fiber having cell-shaped regions in a fiber inside is subjected to weight-reducing treatment to thereby expose the cell-shaped regions onto the fiber surface to form the holes and the stripy recessed parts linearly extending in the fiber axis direction on the fiber surface.SELECTED DRAWING: Figure 1
