Patent number: 9089457Abstract: A bodily fluid absorbent article adapted to absorb bodily fluid over a wide range thereof. An absorbent structure in the bodily fluid absorbent article includes an upper absorbent component and a lower absorbent component. The absorbent structure further includes one of a dispersing surface constituting the upper absorbent component and kept in contact with the lower absorbent component and a dispersing surface constituting the lower absorbent component and kept in contact with the upper absorbent component. Such dispersing surface exhibits a dispersion velocity for bodily fluid higher than those exhibited by the absorbent sections defined immediately above and under this dispersing surface.Type: GrantFiled: September 16, 2011Date of Patent: July 28, 2015Assignee: Unicharm CorporationInventors: Yusuke Kawakami, Atsushi Tsukuda, Hitomi Nakao

Patent number: 4917920Abstract: A fragrant fibrous structure, such as fabrics, apparels or the like, provided with microcapsules encapsulating a perfume and a resinous binder, preferably a silicone resin, in a weight ratio of 2/1 to 1/5, an add-on amount in the aggregate of said microcapsules and resinous binder being 0.3.about.7.0% based on the weight of the portion to which said microcapsules and resinous binder are adhered, of the fibrous structure. The process for preparing the above fibrous structures comprises applying a treating liquid comprising microcapsules composed of an external wall of a formaldehyde based resin enclosing a perfume and a resinous binder, preferably a low temperature reactive organopolysiloxane prepolymer emulsion, preferably together with a pressure absorbing agent, to at least a part of a fibrous structure and then drying the fibrous structure at a temperature of less than 150.degree. C. to fix said microcapsules on fiber surfaces of the fibrous structure.Type: GrantFiled: July 31, 1989Date of Patent: April 17, 1990Assignee: Kanebo, Ltd.Inventors: Akira Ono, Toshikazu Fuse, Osamu Miyamoto, Shoso Makino, Yoshihisa Yamato, Hiroshi Kametani, Susumu Tokura, Hiromi Tanaka, Toru Ito, Hitomi Nakao, Shuji Tokuoka, Toshihide Takeda
