Title:
LAMINATED NONWOVEN FABRIC AND METHOD FOR PRODUCING THE SAME, AND WIPER
Document Type and Number:
Japanese Patent JP2020158900
Kind Code:
A
Abstract:
To provide a nonwoven fabric capable of providing a wiper in which twisting in a ultrafine fiber layer and clogging by dust are less likely to occur even when it has a structure that the ultra fine fibers are located on a wiping surface.SOLUTION: A laminated nonwoven fabric includes a ultrafine fiber layer comprising ultra fine fibers having a fiber diameter of 0.01 μm-10 μm and a substrate fiber layer. The ultrafine fiber layer and the substrate fiber layer are integrated by fiber-interlacing. The ultrafine fiber layer is partially broken and is present in a form of a plurality of lines along one direction of the nonwoven fabric. An average width of a line of the ultrafine fiber layer in a direction orthogonal to the one direction of the nonwoven fabric is 0.1 mm-0.5 mm, and an average distance of adjacent lines of the ultrafine fiber layer is 0.7 mm-1.2 mm.SELECTED DRAWING: None
