Paper Production

Paper Production

Paper is technically defined as a product made from the felting of vegetable fibres that have been appropriately refined in a watery agent. Felting is the process of pressing together these fibres to make a uniform surface: the sheet of paper. Felting or manufacture of sheets of paper can be done:

• by hand,
• by machine: continuous Fourdinier machine, continuous mould machine

In both cases, in order to be felted, the fibres must be put through an initial refining process in order to reduce them to their basic state, their length corresponding to the size of the final sheet of paper required.

Paper Production

The pulp is more or less refined according to the types of paper that are to be produced. For example: the pulp for absorbent paper is only slightly refined, whereas the pulp for tissue paper to go between glossy sheets is obtained after a long process of refining; highly refined pulp is that from which water drains more easily. At the end of the refining process the fibres are given a treatment of “glueing” so as to insure the paper’s ink-holding ability, for both normal and special printing inks. The fibres are glued by use of a natural resinous substance: colophony, previously treated to obtain a colloidal suspension of a milky aspect. These particles or colloids wrap around the fibres making them water resistant. For some time now, synthetically-made chemical products have also been used for the glueing process. Thus prepared, other additives such as colorants, sensitizers, fillers, opacifiers etc are added to the vats of pulp, then to be manufactured either by a continuous Fourdinier machine, a continuous mould machine or by hand, depending on the case.
