Kind Code:
A
Abstract:
To provide a nonwoven fabric excellent in wiping properties, having a surface excellent in followability to irregularities.SOLUTION: A laminated nonwoven fabric comprises a heat-fusible nonwoven fabric layer (A) and an ultra fine fiber nonwoven fabric layer (B) laminated to each other. As a fiber (Fa) constituted of the heat-fusible nonwoven fabric layer (A), at least a composite fiber (Fa1) including at least a first thermoplastic resin composition (Pa11) and a second thermoplastic resin composition (Pa12) is used. A fiber (Fb) constituted of the ultra fine fiber nonwoven fabric layer (B) is made of fiber of polyester resin made by copolymerization with polyethylene glycol in the range of 5 mass% or more and 40 mass% or less, the fiber having an average single fiber diameter of 6.0 μm or more and 20.0 μm or less. The percentage of the heat-fusible nonwoven fabric layer (A) in the thickness direction is 30% or more and 98% or less.SELECTED DRAWING: Figure 1
