Abstract
Wet-spun fibers of β-1,3-glucan, the wet-spun fibers containing β-1,3-glucan as the only constituent molecule and a method for producing the same, and sub-micron fibrils and a method for producing the same. The wet-spun fibers contain only β-1,3-glucan, represented by a specific Chemical Formula (1), as a constituent molecule. The production method of the wet-spun fibers includes preparing spun fibers from a β-1,3-glucan raw material, represented by the specific Chemical Formula (1), by a method (I) in which viscose is prepared from the β-1,3-glucan raw material, or a method (II) in which the β-1,3-glucan raw material is dissolved in a good solvent.
