Title
(EN) METHOD FOR MANUFACTURING NONWOVEN FABRIC WITH UNEVEN PATTERN
(FR) PROCÉDÉ DE FABRICATION DE TISSU NON TISSÉ AVEC UN MOTIF IRRÉGULIER
(JA) 凹凸パターン付き不織布の製造方法
Abstract
(EN) Provided is a method for manufacturing a nonwoven fabric with an uneven pattern that processes a web while delivering the same, wherein the method comprises: a step for preparing a web with a fiber density of 4 - 8 × 10-2 g/cm3; a step for disposing the web so as to follow a surface of a first support body having an uneven pattern on the surface and forming a semifinished product with an uneven pattern having an uneven pattern region wherein the uneven pattern is transcribed while the fibers included in the web are interlaced with one another by spraying a first water flow on the web; and a step for forming a nonwoven fabric by interlacing the fibers included in the semifinished product with an uneven pattern by spraying a second water flow in a region outside of the uneven pattern region in the semifinished product with an uneven pattern.
(FR) L'invention concerne un procédé de fabrication d'un tissu non tissé avec un motif irrégulier qui traite une toile tout en la distribuant, le procédé comprenant : une étape de préparation d'une toile avec une densité de fibres de 4 à 8 × 10-2 g/cm3 ; une étape de disposition de la toile de manière à suivre une surface d'un premier corps de support ayant un motif irrégulier sur la surface et formant un produit semi-fini avec un motif irrégulier ayant une région de motif irrégulier, le motif irrégulier étant transcrit tandis que les fibres comprises dans la toile sont entrelacées les unes avec les autres par pulvérisation d'un premier flux d'eau sur la toile ; et une étape de formation d'un tissu non tissé par entrelacement des fibres comprises dans le produit semi-fini avec un motif irrégulier par pulvérisation d'un second flux d'eau dans une région à l'extérieur de la région de motif irrégulier dans le produit semi-fini avec un motif irrégulier.
(JA) 凹凸パターン付き不織布の製造方法は、ウェブを搬送しながら加工する。その凹凸パターン付き不織布を製造する方法は、繊維密度が4~8×10-2g/cmのウェブを準備する工程と、前記ウェブを、表面に凹凸パターンを有する第1の支持体の前記表面に沿うように配置し、前記ウェブに第1の水流を噴射することにより、前記ウェブに含まれる繊維同士を交絡しつつ、前記凹凸パターンが転写された凹凸パターン存在領域を有する凹凸パターン付き半製品を形成する工程と、前記凹凸パターン付き半製品における前記凹凸パターン存在領域以外の領域に第2の水流を噴射することにより、前記凹凸パターン付き半製品に含まれる繊維同士を交絡して不織布を形成する工程と、を備える。
