Disclosed is a liquid absorbing body and a method of manufacturing the liquid absorbing body which has an excellent swelling property and absorbed liquid holding ability in a vertical state and which is suitable to a mass production at a low manufacturing cost. This liquid absorbing body includes natural cellulose fibers and/or synthetic fibers, a thermally fusible material and a thickening material. This liquid absorbing body is formed by defibering natural cellulose fibers and/or synthetic fibers, a thermally fusible material and a thickening material in air and mixing them to form a mat, heating thus formed mat at a temperature higher than a fusible point of the thermally fusible material and then fixing the thickening material in a web by compressing the mat with a press roller.

Matériau absorbant les liquides, possédant une excellente capacité de gonflement et de retenue d'un liquide absorbé dans un sens perpendiculaire, et qui se prête à la production à grande échelle à des coûts de production réduits. Ce matériau comprend des fibres synthétiques et/ou cellulosiques naturelles, un matériau thermofusible et un matériau épaississant. On le produit en mélangeant et en désagrégeant les matériaux de départ précités à l'air pour former un mat, en chauffant ce mat au moins jusqu'à la température de fusion du matériau thermofusible, et en comprimant ledit mat par l'intermédiaire d'un rouleau compresseur de manière à fixer le matériau épaississant dans la nappe.
