Virgin fibres and recovered paper
In the tissue process both virgin fibres and recovered paper are being used. In the process it is a matter of finding an efficient solution where both virgin fibres and recovered paper play a role. Different fibres demand different processes and this determines the end product properties, and makes the fibre type (recovered or virgin) less important.
The environmental benefits and economic feasibility of recovered paper as a raw material source depend on its availability, transport distance and the quality of the collected material.
Bleaching of fibres
Bleaching is a cleaning process of the fibres and the aim is to achieve a bright pulp, but also to get a certain purity of the fibre in order to achieve the demands for hygiene products and in some cases to meet the requirements for food safety.
There are different methods used today for bleaching ECF (elementary chlorine free( where chlorine dioxide is used, and TCF (totally chlorine free) where ozone, oxygen and hydrogen peroxide is used.
The chemicals used in the process as well as the functional chemicals are assessed from an environmental, occupational health and safety and product safety point of view .
The used functional chemicals are:
Wet strength agent
Dry strength agent
If coloured = Dye
If white Fluorescent whitening agent
If needed Glue
The process chemicals are:
Dispersing agents and surfactants
pH and charge control
Broke treatment chemicals
