Abstract:
(EN) The objective of the present invention is to manufacture an absorbent body with which it is easy to enhance liquid permeability and liquid diffusion. (i) A strip-shaped main sheet (10) in which a non-woven fabric sheet (14) constitutes at least part of a first main surface (10s) is conveyed in a longitudinal direction of the main sheet (10); (ii) a slit (16) is formed in the non-woven fabric sheet (14) at a first position on a conveying route in such a way as to form an incision (17) in the first main surface (10s); (iii) at a second position, particulate matter (11) capable of absorbing and retaining liquid is dispersed into a region of the first main surface (10s) that includes the incision (17), in such a way that the particulate matter (11) is held in the non-woven fabric sheet (14); and (iv) at a third position, a covering sheet (18) which prevents passage of the particulate matter (11) is overlaid on the region of the first main surface (10s) in which the particulate matter (11) has been dispersed. At the second position, the non-woven fabric sheet (14) includes a bulky structure (14k) which constitutes at least part of the first main surface (10s) and which has voids allowing the particulate matter (11) to enter.
(FR) L'objectif de la présente invention est de fabriquer un corps absorbant avec lequel il est facile d'améliorer la perméabilité aux liquides et la diffusion de liquide. (i) Une feuille principale en forme de bande (10) dans laquelle une feuille de tissu non tissé (14) constitue au moins une partie d'une première surface principale (10s) est transportée dans une direction longitudinale de la feuille principale (10); (ii) une fente (16) est formée dans la feuille de tissu non tissé (14) à une première position sur un trajet de transport de manière à former une incision (17) dans la première surface principale (10s); (iii) à une seconde position, une matière particulaire (11) capable d'absorber et de retenir un liquide est dispersée dans une région de la première surface principale (10s) qui comprend l'incision (17), de telle sorte que la matière particulaire (11) est maintenue dans la feuille de tissu non tissé (14); et (iv) à une troisième position, une feuille de recouvrement (18) qui empêche le passage de la matière particulaire (11) est superposée sur la région de la première surface principale (10s) dans laquelle la matière particulaire (11) a été dispersée. Dans la seconde position, la feuille de tissu non tissé (14) comprend une structure volumineuse (14k) qui constitue au moins une partie de la première surface principale (10s) et qui comporte des vides permettant l’entrée de la matière particulaire (11).
(JA) 通液性や液拡散性の向上が容易である吸収体を製造する。 (i)不織布シート(14)が第1の主面(10s)の少なくとも一部を構成する帯状の主シート(10)を、主シート(10)の長手方向に搬送し、(ii)搬送経路の第1の位置で、不織布シート(14)に、第1の主面(10s)に切れ目(17)が形成されるようにスリット(16)を形成し、(iii)第2の位置で、第1の主面(10s)のうち切れ目(17)を含む領域に、液体を吸収し保持することが可能な粉粒体(11)を散布して、粉粒体(11)が不織布シート(14)に保持されるようにし、(iv)第3の位置で、第1の主面(10s)のうち粉粒体(11)が散布された領域に、粉粒体(11)の通過を阻止する被覆シート(18)を重ねる。不織布シート(14)は、第2の位置において、第1の主面(10s)の少なくとも一部を構成し粉粒体(11)が入り込むための空隙を有する嵩高構造(14k)を含んでいる。
