The present invention concerns a process for the covalent attachment of lignin to cellulose in aqueous solutions, which process is characterized by preparing an aqueous mixture of lignin particles modified with tall oil fatty acids (TOFA), and reacting these TOFA-modified lignin particles with cellulose particles. The obtained modified cellulose particles are biodegradable, and have antimicrobial properties, whereby they are suitable for use in antibacterial textile surfaces (sportswear, medical textiles), tissue adhesives and as porous carriers in drug delivery. Further, the material is useful in high-volume products, such as adhesives and dispersants.
