A fibre product, e.g. paper or the like, and a method of manufacturing such product. Besides organic fibres this also contains inorganic fibres, a binding-agent, at least in part in the form of compounds of silicic acid and sodium or potassium, and carbamide and/or propylene glycol. By this method water-glass and mineral wool fibres are added to a suspension of treated cellulose fibres. After further treatment, e.g. the admixture of size, dyestuff, filler and thickener, the suspension and its additives is dried and pressed to obtain the final product. |
