The invention relates to a defibrated cellulose product, in particular fluff pulp, possessing a fibre structure having compressibility under the influence of heat and pressure which structure can be obtained by crosslinking, in the dry state, cellulose fibres which are impregnated with an effective quantity or crosslinking agent and at least one bifunctional, trifunctional or polyfunctional alcohol, and which are defibrated prior to carrying out the crosslinking reaction. The invention also relates to an absorptive pad which consists, at least in part, of the defibrated cellulose product, and also to a method for producing the cellulose product.
