Abstract

The present invention provides an absorbent comprising water-absorbing fibers which has been regulated mainly with respect to fiber orientation and further with respect to basis weight concerning fiber amount and to shape. The absorbent (110) is an absorbent comprising water-absorbing fibers. It comprises: low-basis-weight regions which are formed continuously in a first direction and have a basis weight lower than the average basis weight of the absorbent (110); and high-basis-weight regions which are disposed on both sides of each low-basis-weight region when viewed in a second direction perpendicular to the first direction and which extend along the low-basis-weight regions and have a basis weight higher than the average basis weight. In each of the high-basis-weight regions, the content of longitudinally oriented fibers in the fibers (101) constituting the high-basis-weight region is higher than that of laterally oriented fibers therein. In each of the low-basis-weight regions, the content of laterally oriented fibers in the fibers (101) constituting the low-basis-weight region is higher than that of longitudinally oriented fibers therein.

Description

technical field [0001] The present invention relates to an absorbent body containing water-absorbent fibers and an absorbent article having the absorbent body. Background technique [0002] At present, absorbers containing water-absorbing fibers such as cellulose fibers are widely used in the fields of sanitary products such as disposable diapers and sanitary napkins, cleaning products, and medical products. As described above, although the absorber is used in various fields, when it is actually used in products in each field, it needs to be manufactured to have properties and structures suitable for the use of each product. [0003] In addition, in recent years, multi-layered absorbers and the like in which nonwoven fabrics are laminated on absorbers have sometimes been processed into shapes suitable for respective product uses of the absorbers, and desired functions may be exhibited. [0004] For example, in (Japanese) Unexamined Patent Publication No. 2005-73921, it is p...
