Abstract
A method for producing a natural fiber part may comprise applying an aqueous solution of an inorganic aluminum salt to the natural fiber part and drying the natural fiber part applied with the aqueous solution. The aqueous solution may contain the aluminum salt in a concentration of 2 to 40% by weight. The aluminum salt may include an alum compound. At least one of an inorganic thickening agent or an inorganic stabilizing agent may be added to the aqueous solution.
Claims5
A method for producing a natural fiber part, the method consisting essentially of:
- applying an aqueous solution of an inorganic aluminum salt to the natural fiber part, the aqueous solution consisting essentially of the aluminum salt in a concentration of 2 to 40% by weight;
- and
- drying the natural fiber part applied with the aqueous solution in a temperature range of 30° C. to 90° C.,
- wherein the aluminum salt is an alum compound of the formula MIMIII(SO4)2.12H2O and/or a mixture thereof, and
- wherein at least one inorganic thickening agent, at least one inorganic stabilizing agent, or a mixture thereof is added to the aqueous solution.
