Abstract

See full text

A method of making a dry defibered fluff pulp suitable for absorption products is described. In the making of fluff pulp bentonite (montmorillonite), and optionally an additional inorganic particle compound, such as a synthetic silicate compound, is added to the pulp in an amount that in the final fluff pulp yields an amount of bentonite of 0.2 to 7 kg per ton fluff pulp and optionally an amount of the additional inorganic particle compound of 0.2 to 7 kg per ton fluff pulp, the total amount of retained particle additives amounting to no more than 8 kg per ton fluff pulp. Moreover, a thus made fluff pulp for absorption products, an absorption core for absorption products comprising such dry defibered fluff pulp and optionally a superabsorbent, and an absorption product comprising such a dry defibered fluff pulp and/or an absorption core are described. Moreover the use of such a dry defibered fluff pulp and/or absorption product for production of hygiene products, such as diapers, incontinent pads, sanitary napkins and wiper cloths are described.
