Title:
FIBRILLATED FIBER AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2016030862
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fibrillated fiber that is fibrillated from a polyvinyl alcohol (PVA) single polymer fiber and a method for producing the same.SOLUTION: (1) There is provided a fibrillated fiber which is fibrillated from a PVA single polymer cross-linked fiber that is obtained by introducing cross-linking into a PVA single polymer fiber having a saponification degree of 98 mol% or more and dissolves in water at a temperature of 100°C or more. (2) A water dispersion of a PVA single polymer cross-linked fiber which is formed of a PVA single polymer having a saponification degree of 98 mol% or more, dissolves in water at a temperature of 100°C or more, and has a fineness of 0.1 to 4 denier and a fiber length of 0.2 to 3 mm is injected at 150 to 275 MPa to collide and merge the water dispersion each other. Thus the PVA single polymer cross-linked fiber is fibrillated.SELECTED DRAWING: Figure 2
