  • Publication number: 20110160685
    Abstract: A liquid-permeating sheet (17) having an antibacterial-containing polymer coating part (31) disposed on the side opposite to the skin side is bonded to a back waist area of a diaper base. When a wearer sweats, the sweat penetrates the antibacterial-containing polymer part (31) through the liquid-permeating sheet (17). The antibacterial contained in the antibacterial-containing polymer containing, part (31) then comes into the sweat to inhibit the propagation of Staphylococcus epidermidis.

  • Publication number: 20110118692
    Abstract: A female member for a hook-and-loop fastener is provided. Even when the hook-and-loop fastener part is deformed or an instantaneous impact peel force is applied to the fastener part, the female member does not peel off the male member. When the male member is peeled from the female member, no fluffing caused by shedding of a fibrous material occurs. The female member for a hook-and-loop fastener is constituted of a fibrous material and can engage with a mating male member. The female member is composed of: dense fiber portions arranged in rows and having a high density of the fibrous material; and sparse fiber portions arranged in rows alternately with these dense fiber portions and having a lower density of the fibrous material than the dense fiber portions. The dense fiber portions deform elastically, and this prevents undesirable peeling and diminishes fluffing.

  • Patent number: 7922704
    Abstract: The present invention provides a disposable nursing pad having a layered structure of a liquid-permeable sheet, an absorbent body, and a liquid-impermeable sheet. The liquid-permeable sheet and the liquid-impermeable sheet are adhered to each other. This prevents the liquid-permeable sheet from becoming detached from the absorbent body, and provides a nursing pad having an improved capacity to maintain its three-dimensional shape. A pair of pad pieces 2 and 3, each of which has a layered structure of a liquid permeable sheet piece, an absorber, and a liquid-impermeable sheet piece, is joined so as to form a nursing pad 1 having an approximately conical shape. With the nursing pad 1, a connection portion 4 where pad pieces are joined forms a ridge which serves as the center line of the nursing pad 1. The nursing pad 1 can be folded along the ridge.

  • Publication number: 20090275909
    Abstract: A high-density region-containing sheet having a high-density region and a low-density region, a sheet member produced by joining the high-density region of the high-density region-containing sheet to an elastic member, and a disposable diaper using the sheet member as its chassis are provided. A sheet in a soft state by imparting preheat is pressed between a pair of opposed shaping rolls and having a toothed region and rotatable. Thus, a high-density region-containing sheet where high-density regions and low-density regions are formed is produced. Such two high-density region-containing sheets are joined through an extended elastic member to form a projection/recess pattern. In such a way, a high-density region-containing sheet can be produced. A sheet member in which at least one of two sheets is a high-density region-containing sheet, the high-density regions are joined through an extended elastic member, and a projection/recess pattern can be formed when the elastic member is contracted is produced.

  • Patent number: 7553301
    Abstract: The present invention relates to a method for determining illustrations for a diaper to be worn, for example, by an infant. With the present invention's illustration determination method, for a diaper, comprising a main body, fitted onto the body of an infant, and an illustration displaying part, provided on the main body for displaying an illustration, the abovementioned illustration is determined based on the age in months of the infant. The illustration can arouse interest of an infant definitely since the object of interest of an infant depends on his/her age in months. An infant can thus be made to calm down during diaper exchange and the labor of diaper exchange can be alleviated.
