Title:
COMPOSITE TYPE NONWOVEN FABRIC WIPER AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2020084385
Kind Code:
A
Abstract:
To provide a composite type nonwoven fabric wiper that is excellent in appearance and use feeling.SOLUTION: A composite type nonwoven fabric wiper is made by laminating a pulp fiber web on a spun-bonded nonwoven fabric. The spun-bond nonwoven fabric SW is formed by including multiple fusion points MP. The multiple fusion points MP are disposed linearly and spaced equally on a longitudinal line LL in parallel with a flow direction MD of the nonwoven fabric and a traverse line TL perpendicular to the flow direction, respectively. Spaces on the longitudinal line and the traverse line are set so as to be the same length as each other. The fusion points MP are disposed so that a first distance FD between centers of gravity of the fusion points that are adjacent to each other on the line is different from a second distance SD between centers of gravity of the fusion points that are adjacent in an oblique direction. Area of a fusion point is set to 0.10 to 0.50 mm, area ratio of fusion points to 7 to 20%, shorter one of the first distance and the second distance to 0.70 to 1.80 mm.SELECTED DRAWING: Figure 1
