A hydrogel-forming multicomponent fiber includes: at least one first fiber component; and at least one second fiber component. The first and the second fiber components are selected independently of one another from a group consisting of polysaccharides and/or polysaccharide derivatives. The first fiber component is produced from a polysaccharide and/or a polysaccharide derivative having a water solubility of more than 50% by weight. The multicomponent fiber has a water solubility of less than 15% by weight.

Methods for producing cellulose articles having controlled release of active ingredient include dispersing pulp in aqueous direct solvent for cellulose to form a slurry. Organically modified or ion-exchange-activated phyllosilicate is homogenized in a direct solvent for cellulose with exfoliation by shearing, then mixed with the slurried pulp. A mixture of active ingredient and a lipophilic matrix material or a water-in-oil ('W/O') emulsion containing active ingredient is stabilized with thickener, converted into a gel-like paste, and mixed with the slurried pulp. Water is stripped from the mixture until all cellulose is dissolved, the mixture is formed into shaped articles, and dried. Exemplary active ingredients include cosmetic active ingredients, fat-soluble vitamins or apolar plant extracts. Domains of active ingredient and matrix material or emulsion containing active ingredient are present as fine divisions within the inventive articles. Exemplary shaped articles include functional fibers in knitted, woven and nonwoven fabrics; paper; foils and membranes.

Multifunctional coating films that can be applied in liquid form are provided for compressing, sealing, covering and preserving surfaces. The films include a composition of polysaccharide materials and/or homo- or heteroglycan water-soluble polysaccharide derivatives, polyol spacers, and crosslinkers with carbonyl or carboxylic function(s). As-applied, the composition is water-soluble and reactive, but after hardening it is capable of absorbing water or swelling, impermeable to water vapour, stable against water and UV and can be biologically degraded in a controlled manner. By reacting polysaccharide materials, polysaccharide derivatives and polyol spacers with cross linkers having carbonyl or carboxylic function(s), mechanically stable flexible films are obtained, which retain their mechanical properties up to a foreign material content of 80%. The films can swell in a controlled manner and can bind up to 75% water relative to their dry weight, corresponding to the degree of crosslinking and the spacer that is used.

The invention relates to a thermoplastic processible aminoplast resin, a method for its production and a fine fiber non-woven material as textile area of fibers from aminoplast resins, in particular duroplastic triazine resins, which have an average fiber diameter of 0.1 to 100 &#x3bc;m and between 1 and 1000 branching arms and between 1 and 300 branching points per square millimeter. The invention also relates to a method for production of duroplastic fine fiber non-woven material in which a melt of melamine resin is pressed through spinning nozzles and blown by the escaping hot air to fine fibers, the fine fibers are separated from the air stream and deposited to a non-woven material consisting of a tangled layer, a treatment with a media causing cross-linking and a neutralization step follows, and the fine fibers are glued to a non-woven material in a subsequent thermal after-treatment, whereat the thermal after-treatment comprises two steps.
