POLYVINYL ALCOHOL FIBER, AND NONWOVEN FABRIC COMPRISING THE SAME

Title:

POLYVINYL ALCOHOL FIBER, AND NONWOVEN FABRIC COMPRISING THE SAME

Document Type and Number:

Japanese Patent JP3828550

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide readily-fibrillable fibers of PVA polymer, having good chemical resistance, hydrophilicity, weatherability and water resistance.
SOLUTION: The PVA fibers have a flattened cross-sectional profile and have a mean thickness D (μm) that satisfies the formula: 0.4≤D≤5 (wherein D=S/L; S indicates the cross-section area (mum2) of the fibers; and L indicates the length (μm) of the major side of the cross section of the fibers).
