摘要： An object of the present invention is to provide a particle-shaped water absorbing agent having a remarkably improved surface color and excellent water-absorbing properties (better water absorption capacity, and lower water soluble content and residual monomer content) at the same time. In order to attain the object, a particle-shaped water absorbing agent according to the present invention is a particle-shaped water absorbing agent whose main component is a polyacrylic acid and/or a salt thereof, the particle-shaped water absorbing agent having a surface color of Hunter b value in a range of - 5 to 10, and having a cross-linking absorption property index (CPI) in a range of 1 to 100, the CPI defined by the following two equations: GEX = GVs + 17 / Ln water soluble content ; CPI = GEX / residual monomer content × 100 where GVs is gel volume in saline, Ln (water soluble content) is a logarithm natural of water soluble content.

摘要： A binder is applied to fibers (600) to bind particles (602) to the fibers. The fibers have hydrogen bonding functional groups. The particles have functional groups capable of forming a hydrogen bond or a coordinate covalent bond. The binder comprises binder molecules, wherein the binder molecules have at least one functional group that forms a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that forms a hydrogen bond with the fibers. A substantial portion of the particles that may be adhered to the fibers are adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

摘要： A densifying agent is applied to fibers in order to improve the densification properties of the fibers. The fibers have hydrogen bonding functional groups. The densifying agent are denser than the fibers to which the densifying agent is applied. The densifying agent can be organic or inorganic. The improved densification properties are observed without the presence of particles bound to the fibers or in the presence of particles that are not bound to the fibers. Softening agents can also be applied to the fibers in order to soften the fibers and articles including such fibers. Softening agents may be selected from the group of densifying agents.

摘要： The present invention relates to absorbent articles such as female sanitary napkins, adult incontinence devices, and the like. Still more particularly, the present invention concerns absorbent articles having flaps and zones of differential extensibility for relieving the stresses that develop in the flaps when the flaps are folded down and under a wearer's undergarment. The zones of differential extensibility are not exclusively made of precorrugated or ring-rolled portions.
