Method of producing a fibrous web containing fillers

摘要

A method of producing a fibrous web on a paper or cardboard machine from an aqueous furnish containing fibres mainly derived from lignocellulosic material, fillers and any conventional additives. According to the method the fillers are admixed with a nanometer sized polyelectrolyte complex before they are contacted with the fibres and any additives. By means of the invention, surface strength, tensile strength, tensile stiffness and/or bulk can be improved at a given filler content. Also dusting of such webs can be reduced.
