no. 1 Embodiment approach

[0037] figure 1 It is a schematic diagram which shows the manufacturing apparatus of the raised sheet which concerns on embodiment of this invention. exist figure 1 , the base material sheet 1 wound into a roll is fed out in the MD (Machine Direction: longitudinal) direction by the feed roller 2 . The base sheet 1 is a sheet made of paper, synthetic resin, nonwoven fabric, etc., but preferably nonwoven fabric. As the nonwoven fabric, a spunlace nonwoven fabric, a spunbonded nonwoven fabric, a thermally bonded nonwoven fabric, an airlaid nonwoven fabric, a point bonded nonwoven fabric, and the like can be used.

[0038] On the other hand, the fiber aggregate 3 is fed out in the MD direction by the feed roller 2, and in the width direction (CD: Cross Direction, transverse direction) of the base material sheet 1 in a region of a predetermined width including at least the center and the base material sheet. 1 stack. As the fiber aggregate 3, a bundle of fibers in which a large...

Abstract

Provided is a method for efficiently obtaining a raised sheet as a cleaning sheet that has a raised cleaning section and can effectively collect waste. This method for manufacturing a raised sheet isprovided with: a step for laminating a base sheet and a fiber assembly; a step for applying a load to the fibers of the fiber assembly without heating; a joining step for partially joining the fiber assembly and the base sheet to form a joining section; a cutting step for cutting the fiber assembly at a site where the fiber assembly and the base sheet are not joined and forming a fiber bundle joined to the base sheet at the joining section; and a step for spraying a fluid on the fiber bundle to raise the fibers.

Description

technical field [0001] This invention relates to the manufacturing method of the raising sheet used as a cleaning sheet etc., and the cleaning sheet which has the cleaning part which raised. Background technique [0002] Cleaning sheets for wiping and cleaning dust, dust, and the like adhering to floors, walls, and the like are widely used. Such a cleaning sheet is provided with a cleaning portion formed of a large number of fibers on a base sheet formed of nonwoven fabric, etc. When the cleaning portion is brought into contact with the floor, wall, etc. between. In recent years, various shapes of cleaning sheets have appeared. For example, there are cleaning sheets in which fiber bundles are bonded to one side of the base sheet and wound around a base mounted on the front end of the handle. There are also cleaning sheets in which fiber bundles are bonded. A plurality of substrate sheets are stacked to form a pouch having a handle insertion opening, and the cleaning sheet ...
