The aim of the project is to determine the effects of surface adsorption and deposition of wood resin, glucomannans, pectins and common fixing agents on the properties of various pulps fibres, both in water systems and in paper sheets.Various amounts of pure detrimental substances are adsorbed/deposited onto washed pulps such as bleached kraft pulp and TMP.Handsheets are prepared and the sheets are analysed chemically and tested for various paper properties.
