1. Study of Paper Dry Strength Additives on Cellulose Fibres
Sammanfattning : Paper packaging is commonly found in the form of paper and cardboard boxes, but recently paper packing is being used in food packaging, trays, beverage packaging and even paper straws, among others. Paper strength additives have been developed to increase the efficiency of the joint strength and the joint areas and potentially maintain bulk in paper products. LÄS MER
2. Polyelectrolyte Complexes : Their Characterization and use for Modification of Wood Fibre Surfaces
Sammanfattning : For economical reasons filler particles and less expensive fibre raw materials are more frequently used in papermaking. This influences the mechanical properties of the formed papers in a negative way and it is therefore necessary to add strength-enhancing agents to the papermaking furnish. LÄS MER
3. Chemical Modification of Cellulose Fibres and Fibrils for Design of New Materials
Sammanfattning : Due to the growing interest in biobased materials in today’s society, where the need for a cyclic economy is obvious, there has been a huge increase in the interest for using cellulose due to its excellent mechanical and chemical properties. However, the properties of cellulose have to be modified and improved in order to satisfy advanced material applications where the cellulose properties can be tuned to fit the properties of other components in composite mixtures.
