Definitions
- the present invention relates to a filler-fiber composite, a process for its production, the use
- the invention relates to a filler-fiber composite in which the mo ⁇ hology and particle size of the mineral filler are established prior to the development of the bond to the fiber. Even more particularly, the present invention relates to a PCC filler-fiber composite, wherein the desired optical and physical properties of the paper produced therefrom are realized.
- particulate fillers such as calcium carbonate, talc and clay on fibers for the
- an object of the present invention is to produce a filler/fiber composite.
- object of the present invention is to provide a method for producing a filler/fiber composite.
- Another object of the present invention is to produce a filler/fiber composite that maintains physical properties such as tensile strength, breaking length and internal bond strength. Still a further object

- a “seed” is defined as a
- the 2.3:1 Ca(OH) 2 /CaCO slurry was transferred to an agitated 20-liter storage vessel. Transferred 2 liters of the 2.3:1 Ca(OH) 2 /CaCO slurry to a first 4-liter agitated, double jacketed stainless steel reaction vessel with agitation set at 1250 ⁇ m and
- calcium carbonate had a predominantly rhombohedral mo ⁇ hology.
- Percol 292 percent cationic polyacrylamide based on the volume of fibrils at 1.5 per cent
- a fibril is produced by refining (any pulp refiner known in the pulp processing industry)
