  • Patent number: 5231122
    Abstract: A fibrous composition for absorbent pads which, in addition to cellulose fibers, also contains first and second synthetic polymeric materials. At least the second polymeric material is constituted by synthetic fibers which have a higher melting point than that of the first polymeric material. The fibrous mixture is formed into the desired shape, for example, an absorbent body for disposable sanitary products, by pneumatic means. The absorbent body thus formed is then heat-treated to a temperature higher than the melting point of the first polymeric material but lower than that of the second polymeric material for a period of time so as to melt the first polymeric material and form bonding points or bridges between at least the synthetic fibers which have not melted and which constitute the second polymeric material. The absorbent body is cooled to a temperature such that the first polymeric material sets, bonding at least the synthetic fibers together so as to form a framework containing the cellulose fibers.
