Modification of Cellulose Products by the Use of Chitosan and Chitosan-Alginate Nano-Particles

Aim of the presented research was the improvement of fibrous cellulosic products for uses in hygiene and medical sectors. Nano-particles of bioactive polysaccharides were imparted to cellulosic fibrous products to modify their properties: physical–chemical like absorption, biological like antibacterial and antifungal activity, and mechanical. Fibrous materials like dressing gauze, wood-wool, and hygiene tissues were modified by the addition of chitosan and chitosan-alginate nano-particles. Padding and freeze-drying was applied in the coating of the fibrous materials with the nano-sized polymers.
