The present method generally relates to a method for production of absorbent material having improved sorptive capacity, which material comprises cellulosic fibres, wherein said method comprises treating said fibres, in the presence of water, with a hydrophobic substance having a specific surface area of at least 50 m.sup.2 /g, wherein the treatment comprises contacting said substance and said fibres together when the fibres have a dry content of at least 20%.

Absorbent material and production thereof

A method in which a sheet of cellulosic fibres is shredded into fluff wherein, prior to shredding, the fibres are treated in the presence of water with a hydrophobic substance having a specific surface area of at least about 50 m.sup.2 /g, to yield improved sorptive capacity; fluff obtainable by the method; absorbent articles comprising such fluff; use of a substance of said kind for improving the sorptive capacity of absorbent material comprising the fibers; a process for production of absorbent material obtained by shredding a sheet of such fibers in which the fibers, prior to shredding, have been treated in the presence of water with a substance of said kind to yield improved sorptive capacity; and absorbent material obtainable from the process.
