The object of the present invention is to provide a method of reducing the odor of urine; and an article functioning to reduce the odor of urine. The present invention relates to the method comprising using a compound(s) reactive with aldehydes to thereby reduce the urine odor. Moreover, the present invention relates to the article, especially one for body fluid absorption, which functions to reduce the odor of urine by having compounds reactive with aldehydes to be present in absorption articles. As the compounds reactive with aldehydes, organic amines, organic amine salts, compounds producing organic amines by the reaction with discharges, organic amines, amide compounds, and compounds having a mercapto group can be used.

Method of reducing urine odor and article functioning to reduce urine odor

High water-absorbent resin composition

To control a flow of body fluid generally occurring on the liquid-permeable topsheet for body fluid absorbent article in a predetermined direction, here is disclosed an improved liquid-permeable topsheet made of thermoplastic synthetic resin comprising a plurality of first direction ribs and a plurality of second direction ribs crossing the first direction ribs so as to a unique rib structure. Tops 7 of the second direction ribs 3 are connected with opposite sides 6 of the respective first direction ribs 2 and each pair of adjacent first direction ribs 2 define a groove 10 serving to guide the body fluid in the predetermined direction.
