Abstract:
A process for manufacturing structured material by providing cellulose fibres and at least one filler and/or pigment, combining the cellulose fibres and the at least one filler and/or pigment, fibrillating the cellulose fibres in the presence of the at least one filler and/or pigment until a gel is formed, subsequently providing additional non-fibrillated fibres, and combining the gel with the additional non-fibrillated fibres.

Claim (Index 30):
A process for manufacturing a structured material, comprising the steps of:\n (a) providing cellulose fibres; (b) providing at least one filler and/or pigment selected from the group consisting of precipitated calcium carbonate (PCC), natural ground calcium carbonate (GCC), surface modified calcium carbonate, dolomite, talc, bentonite, clay, magnesite, satin white, sepiolite, huntite, diatomite, silicates, and mixtures thereof; (c) combining the cellulose fibres of step (a) and the at least one filler and/or pigment of step (b) at a weight ratio of fibres to filler on a dry weight basis of from 1:33 to 10:1; (d) fibrillating the cellulose fibres in an aqueous environment in the presence of the at least one filler and/or pigment from step (c) until a nano-fibrillar cellulose gel is formed, wherein the formation of the gel is verified by monitoring the viscosity of the mixture in dependence of the shearing rate, wherein the viscosity decrease of the mixture upon step-wise increase of the shearing rate is larger than the corresponding viscosity increase upon subsequent step-wise reduction of the shearing rate over at least part of the shear rate range as shearing approaches zero; (e) providing additional non-fibrillated fibres; (f) combining the nano-fibrillar cellulose gel of step (d) with the non-fibrillated fibres of step (e), so that the combination of the nano-fibrillar cellulose gel and the non-fibrillated fibres comprises 0.5 to 20 wt. % of the nano-fibrillar cellulose gel, expressed by the cellulosic content of the nano-fibrillar cellulose gel, on a dry/dry basis; and (g) dewatering the combination of step (f) to form a base structure.
