Manufacturing method of absorptive article and absorption article

Abstract

The invention provides a manufacturing method of an absorptive article and the absorptive article. Simple and compact equipment can be utilized for manufacturing an absorber which is formed by clamping a reinforced layer among multiple accumulation layers. The problem is solved by adopting the following scheme: an accumulation material is respectively accumulated in an absorber mould at a first accumulation position and a second accumulation position which are sequentially configured on the outer peripheral surface of a fiber accumulation roller at an interval in the rotation direction of thefiber accumulation roller; meanwhile, a reinforced layer such as a banded non-woven fabric is supplied between the first accumulation position and the second accumulation position, the reinforced layer passes a position above the absorber mould on the outer peripheral surface of the fiber accumulation cylinder and is continuous in the rotation direction of the fiber accumulation roller, an absorber is formed in the absorber mould, and the absorber is provided with a first accumulation layer accumulated at the first accumulation position, a second accumulation layer accumulated at the second accumulation position and the reinforced layer clamped between the first accumulation layer and the second accumulation layer.

Description

technical field [0001] The present invention relates to a method for manufacturing an absorbent article having an absorbent body in which a reinforcing layer such as a sheet is directly sandwiched between accumulation layers made of short fibers or the like, and the absorbent article. Accumulative material accumulated. Background technique [0002] Absorbent bodies of absorbent articles such as disposable diapers and sanitary napkins are often fibrous bodies obtained by splitting a short fiber sheet (for example, a pulp sheet obtained by forming pulp fibers into a sheet) with an opener. Fiber opening (also called pulverization), scattering the fiber opening with the air flow, mixing superabsorbent polymer particles as necessary, and accumulating the mixture in the absorbent body mold (fiber accumulation) (see Patent Document 1) . [0003] Such an absorbent body of the piling type is generally obtained by, for example, Figure 20 Manufacturing equipment shown to manufacture...

AI Technical Summary

Problems solved by technology

[0006]However, in the case of manufacturing an absorbent body in which a reinforcement layer such as a sheet is directly sandwiched between a plurality of accumulation layers, the application of the conventional fiber accumulation drum In this method, multiple accumulating layers are sequentially produced by using a plurality of fiber accumulating rollers, a reinforcing layer such as a sheet is laminated on an accumulating layer formed by one accumulating roller, and then, a fiber accumulating body formed by another accumulating roller is placed on the accumulating layer. Therefore, there is a problem that the manufacturing equipment becomes complicated and large, and the equipment cost and electricity cost are also increased.
