摘要:
The present invention provides an absorbent body containing absorbent fibers in which fiber orientation is mainly adjusted, and fiber basis weight and shape are additionally adjusted. The absorbent body 110 of the present invention is an absorbent body containing absorbent fibers, a plurality of low fiber basis weight regions formed continuously in the first direction with a fiber basis weight that is less than an average fiber basis weight of the absorbent body 110, and a plurality of high fiber basis weight regions, formed along and on both sides of the low fiber basis weight regions in relation to the second direction perpendicular to the first direction, with a fiber basis weight that is greater than the average fiber basis weight of the absorbent body 110. The content of longitudinally oriented fibers in the fibers 101 making up the high fiber basis weight regions is greater than that of laterally oriented fibers, and the content of longitudinally oriented fibers in the fibers 101 making up the low fiber basis weight regions is greater than that of laterally oriented fibers.
摘要:
A nonwoven fabric that is not easily damaged during use is provided. A fiber web supported by a predetermined supporting member from the lower face side is blown with fluid, mainly composed of gas, from the upper face side of the fiber web to move fibers that constitute the fiber web, thereby forming at least a plurality of open areas. The nonwoven fabric includes a plurality of open areas continuously formed along a predetermined direction with a predetermined interval and a plurality of joining portions, each of which are formed between the open areas adjacent to each other in a predetermined direction.

It is an objective of the present invention to provide a nonwoven fabric prepared so as to be able to rapidly transfer a predefined liquid. The nonwoven fabric is formed by jetting a fluid, which consists mainly of gaseous matter, to a fiber web 100 supported from beneath by a predefined breathable support member, from an upper surface side in order to move fibers in the fiber web 100. A number of groove portions 1 and a number of convex portions 2 are formed on a jetted area of the nonwoven fabric in the direction in which the area is extended, and the fiber density of the groove portions 1 is less than the fiber density of the convex portions 2.

Nonwoven fabric including concaves and convexes, and at least a fiber basis weight which is adjusted, and its manufacturing method are provided. The nonwoven fabric 110 is formed into a substantially sheet-like shape of predetermined thickness and its fiber basis weight is adjusted by directing a fluid, mainly consisting of gas, to a fiber web 100, the fibers of which have a high degree of freedom to move. The nonwoven fabric 110 includes a plurality of groove portions 1, which are low basis weight portions, and a plurality of convex portions 2, which are high basis weight portions, that are continuously formed along the groove portions 1 and are adjacent to each of the plurality of groove portions 1. The Fiber basis weights of the plurality of groove portions 1 are less than those of the plurality of convex portions 2.

A multilayer nonwoven fabric includes a first fiber layer and a second fiber layer laminated and arranged on a first surface of the first fiber layer. A plurality of groove portions are formed along a prescribed direction in a shape depressed in a thickness direction of the multilayer nonwoven fabric. A plurality of raised ridge portions are formed adjacent to the plurality of groove portions in a shape projected in the thickness direction. The basis weight of the raised ridge portion is greater than the basis weight in regions, which include the bottoms of the groove portions. The second fiber layer including each of the plurality of raised ridge portions is in such a shape that a surface, on the side of the first fiber layer, of the second fiber layer is projected in the same direction as the direction in which the second surface of the first fiber layer is projected.
