摘要:
A fibrous product, the absorption and desorption properties of which have been improved and which comprises a fibrous substrate which has, on at least one of it surfaces, a small quantity of a modified starch, and a method of producing it. According to the present invention, onto at least one surface of the fibrous product is applied 0.01-1.0 g/m2 of starch ether ester, anionic starch ester, or starch ether or ester, from a diluted aqueous solution or aqueous dispersion. By means of the present invention it is possible efficiently to reduce the absorption of printing ink into a surface to be printed. Consequently, the desired density is achieved with a smaller printing ink quantity and, at the same time, harmful print-through of imprints is reduced.

摘要:
The present invention relates to a light, biodegradable, organic pigment and filler, and a method of manufacturing it. According to the present invention, a solution comprising a starch derivative is first prepared by dissolving the starch derivative into a suitable solvent, and, after that, the solution is brought into contact with a non-solvent to precipitate the starch derivative from the solvent, and, as a result, a dispersion is obtained, one which comprises a precipitate consisting of starch derivative and a liquid phase formed of the solvent and the non-solvent, after which the solvent is removed from the liquid phase and the precipitate is separated from the non-solvent and recovered. The present invention can be used to manufacture both a product comprising 100-300 nm spherical particles, which is suitable for use as a pigment, and a coral-like, porous product which is particularly suitable as a filler.
摘要:
A material which is suitable as filler or coating pigment for a fibrous web and a method for manufacturing thereof. According to the method, a feed comprising organic polymer material is cooled to at least approximately −50° C., after which it is refined in a jet refiner to a desired particle size. The present invention generates uniform pigment particles which comprise, for instance, starch esters, and which particles have a porous surface structure, in which case they are suitable for instance as coating pigments and fillers for offset and ink-jet papers.

摘要:
An adhesive binder for bonding together lignocellulosic particles, fibers and flakes of vegetable origin to form particle boards, fiber boards, flake boards and similar wood-based products, comprising a solublized fraction obtained by enzymatic treatment of fibrous, lignocellulosic raw materials. The present binder can be obtained by treating fibrous lignocellulosic raw material with a hydrolytic enzyme in an aqueous medium, recovering the solubilized material of the enzymatic treatment, forming an aqueous suspension containing said material and an oxidase, and oxidizing said material in the presence of said oxidase by introducing oxygen-containing gas into the supension. This method thus produces an increased amount of a water-soluble fraction containing carbohydrates, extractives and lignin useful as an adhesive binder.
