Description

本発明は、上記課題を解決するため、以下の構成を採用した。
すなわち、本発明の不織布の製造方法は、水分を含んだ抄紙原料を支持体上に供給して、該支持体上に繊維シートを形成する工程と、繊維シートを乾燥する工程と、繊維シートを乾燥する工程によって乾燥した繊維シートの一部に、繊維シートを乾燥する工程によって乾燥した繊維シートの水分率よりも高い水分率に水分率を上昇させた領域を形成する工程と、繊維シートの水分率を上昇させた領域に高圧水蒸気を噴射する工程とを含む。
本発明の他の不織布の製造方法は、ウェブを支持体上に供給して、該支持体上に繊維シートを形成する工程と、繊維シートの一部に、繊維シートの水分率よりも高い水分率に水分率を上昇させた領域を形成する工程と、繊維シートの水分率を上昇させた領域に高圧水蒸気を噴射する工程とを含み、水分率を上昇させた領域を形成する工程は、前記繊維シートの水分率を上昇させた領域における繊維シートの水分率を、１０％以上、８０％以下とする。
The present invention employs the following configuration in order to solve the above problems.
That is, the method for producing a nonwoven fabric of the present invention comprises a step of supplying a papermaking raw material containing moisture onto a support, forming a fiber sheet on the support, a step of drying the fiber sheet, and a fiber sheet. Forming a region where the moisture content is increased to a moisture content higher than the moisture content of the fiber sheet dried by the step of drying the fiber sheet in a part of the fiber sheet dried by the drying step, and moisture of the fiber sheet Injecting high-pressure steam into the region where the rate is increased.
Another method for producing a nonwoven fabric of the present invention includes a step of supplying a web onto a support and forming a fiber sheet on the support, and a moisture content higher than the moisture content of the fiber sheet in a part of the fiber sheet. forming a region where moisture content is increased the rate, look including the step of injecting high-pressure steam to the area to increase the moisture content of the fiber sheet to form a region where moisture content is increased, the The moisture content of the fiber sheet in the region where the moisture content of the fiber sheet is increased is set to 10% or more and 80% or less .
