摘要： The invention provides a method of controlling retention on a forming fabric in a paper making process, an intermediate product for use in the method, as well as use of material for the intermediate product. For making the intermediate product at least one paper making chemical is added to a slurry of fine cellulose fibres such as micro fibrillated cellulose (MFC), the specific surface area of those fibres being larger than that of the fibres of the main fibrous suspension for paper making, causing the paper making chemical being adsorbed on the fine cellulose fibres. This intermediate product is then incorporated in the main fibrous suspension before the suspension is supplied from the paper machine head box to the forming fabric. Other paper making chemicals may be added to the fibrous suspension before or after addition of the intermediate product, so that interactions between different chemicals are prevented. The invention permits an increased retention in general as well as improved control of retention of paper making chemicals separately and/or in relation to each other.

摘要： The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair (102, 103) is placed in the wet end. The electrode pair (102, 103) is supplied with a current/voltage from a power source (100), so that an electric field is set up between the electrode pair (102, 103), causing the material particles in the pulp suspension in the wet end to be electrically charged in a desired manner and to move in a desired manner in the pulp suspension in the wet end. The current/voltage of the power source (100) is controlled by means of a measuring and control unit (101) so as to cause the material particles in the pulp suspension to be electrically charged and to move in a desired manner, thus allowing the retention, formation and orientation of the material particles in the pulp suspension to be substantially improved.
