PROBLEM TO BE SOLVED: To provide a method of manufacturing an absorber which can suppress fibrillation faults of a synthetic fiber regardless of a feeding speed of a synthetic fiber sheet and can manufacture the absorber including the synthetic fiber and a pulp fiber at a desired mixture ratio.SOLUTION: A method of manufacturing an absorber 100 includes a fibrillation process in which a belt-like pulp sheet 10as formed of a pulp fiber 10a and a belt-like synthetic fiber sheet 10bs formed of a synthetic fiber 10b are fibrillated by using a fibrillation machine 21 and an accumulation process in which the fibrillated pulp fiber 10a and synthetic fiber 10b are mixed while conveying in the scattered state and are accumulated in an accumulating recessed part 41. The method of manufacturing in the invention includes a strength reduction process for performing processing of reducing tensile strength of the synthetic fiber sheet 10bs in a conveyance direction (Y direction) as a preprocessing of the fibrillation process.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】合成繊維シートの供給速度に関わらず合成繊維の解繊不良を抑制でき、所望の混合比で合成繊維とパルプ繊維とを含む吸収体を製造できる吸収体の製造方法を提供すること。【解決手段】本発明の吸収体100の製造方法は、パルプ繊維10aから形成された帯状のパルプシート10as及び合成繊維10bから形成された帯状の合成繊維シート10bsを、解繊機21を用いて解繊する解繊工程を備える。また解繊されたパルプ繊維10a及び合成繊維10bを、飛散状態にて搬送しながら混合し、集積用凹部41に集積する集積工程を備える。本発明の製造方法は、解繊工程の前工程に、合成繊維シート10bsの搬送方向(Y方向)の引っ張り強度を低下させる加工を施す強度低下工程を備える。【選択図】図2
