Title:
NONWOVEN FABRIC AND SUBSTRATE FOR ADHESIVE SKIN PATCH
Document Type and Number:
Japanese Patent JP2021070884
Kind Code:
A
Abstract:
To provide a nonwoven fabric and a substrate for an adhesive skin patch excellent in nonwoven fabric strength in a thickness direction and excellent in adhesive feeling.SOLUTION: A nonwoven fabric comprises highly crimped fibers as a main constituent in which crimping of latent crimpable fibers is developed. The 50% modulus strength per unit basis weight of the nonwoven fabric is 0.020 N/5 cm/(g/m2) or more both in a machine direction and in a cross direction orthogonal to the machine direction. An aspect ratio (MDS/CDS) of the tensile strengths of the nonwoven fabric which is a ratio of a tensile strength (MDS) in the machine direction to the tensile strength (CDS) in the cross direction is 2.0 or more. When the nonwoven fabric is extended by 50% in the machine direction, a shrinkage factor in the cross direction is 20% or less. Thus, it is possible to realize a nonwoven fabric excellent both in nonwoven fabric strength in the thickness direction and in adhesive feeling.SELECTED DRAWING: None
