The chitosan is microcrystalline chitosan and the product contains microcrystalline chitosan particles bonded to adjacent particles and the structure of the fibrous product mainly by hydrogen bonds. In a method of manufacture of the modified products, the microcrystalline chitosan gel-like dispersion is brought in contact with the products, whereafter the products are dried.
