Abstract: The present invention provides a biological fiber composite dressing. The biological fiber composite dressing includes: a cloth membrane having a first surface layer and an opposing second surface layer, wherein the cloth membrane has cloth membrane fibers; and a biological fiber membrane having a third surface layer and an opposing fourth surface layer, wherein the biological fiber membrane is formed by bacteria of the genus Gluconacetobacter, and the fourth surface layer is combined with the first surface layer, and a plurality of biological fibers being wound and combined with the cloth membrane fibers are extended along the fourth surface layer of the biological fiber membrane, such that the moisturizing effect of the dressing can be enhanced by the biological fiber membrane, thereby carrying more active ingredients.

Abstract: The present invention relates to a process for the production of a surface coated support material wherein said process comprises contacting a support material with an aqueous dispersion of nanocellulose. The surface coated support material can be used in a composite material. The invention therefore further relates to the surface coated support material per se, a composite comprising the material, a process for the production of the composite material and an article produced from the composite material.

Abstract: A method of producing regenerated cellulose and hemicellulose from a fiber pulp which is prepared by using chemical cooking. Hemicellulose and, correspondingly, cellulose is separated from the pulp, in order to form separate fractions, by dissolving them in such a solvent or an aqueous solution of it, from which they are precipitated by adding water, after which the regenerated hemicellulose and cellulose can be recovered. Hemicellulose-containing pulp, which for example is used as raw material of paper, can be efficiently fractionated into polymeric hemicellulose-rich fractions and very pure cellulose fractions, such as regenerated cellulose fiber, various cellulose particles or cellulose films.

Abstract: A process for the preparation of water-soluble cellulose hydrolysis products, which comprises admixing cellulose with an ionic liquid in which the cellulose has at least some solubility, said ionic liquid state at a temperature at or below 150 -C, and treating the resulting solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25 -C.

Abstract: A process is described for the preparation of water-soluble cellulose hydrolysis product. The process comprise admixing cellulose with an ionic liquid capable of solvating or dissolving at least some of the cellulose, said ionic liquid being a compound comprises solely of cations and anions and which exists in a liquid state at a temperature at or below 150° C., and in which the anions are selected from halide and cyanate; and treating the resulting solvate or solution with an acid in the presence of water, said acid having a pKa in water of less than 2 at 25° C.

Abstract: The invention provides protein adhesives and methods of making and using such adhesives. One type of protein adhesive described herein contains lignin and ground plant meal or an isolated polypeptide composition obtained from plant biomass. Other types of protein adhesives described herein contain a plant protein composition and either a hydroxyaromatic/aldehyde, urea/aldehyde, or amine/aldehyde component.

Abstract: A dental filling material comprising an inner core and outer layer of material disposed and surrounding the inner core, both the inner core and outer layer of material each containing a thermoplastic polymer. The thermoplastic polymer may be biodegradable. A bioactive substance may also be included in the filling material. The thermoplastic polymer acts as a matrix for the bioactive substance. The composition may include other polymeric resins, fillers, plasticizers and other additives typically used in dental materials. The filling material is used for the filing of root canals.

Abstract: The invention relates to a vapor barrier for use in the thermal insulation of buildings which can be used, in particular, for thermal insulation procedures in new buildings or in the renovation of old buildings. The vapor barrier in accordance with the invention is thereby capable of achieving water vapor exchange under different ambient conditions. This is achieved by using a material which has a water vapor diffusion resistance which is dependent on the ambient humidity and which also has adequate tensile strength and tear resistance.

Abstract: Cellulose is dissolved in an ionic liquid without derivatization, and is regenerated in a range of structural forms without requiring the use of harmful or volatile organic solvents. Cellulose solubility and the solution properties can be controlled by the selection of the ionic liquid constituents, with small cations and halide or pseudohalide anions favoring solution.

Abstract: Utilization of gelatine in the form of sheets as support for images and the transfer thereof to surfaces or to tridimensional bodies through humidification of the sheet and, in certain cases, further subjecting said sheet to heat at a temperature comprised between 35° and 45° approximately. The surface on which the image contained in the gelatine sheet is applied can be a die-cut laminar material, with the possibility of separating each individual element from said die-cut material so that each individual element contains the corresponding image portion.

Abstract: A radiation-curable composition is comprised of the reaction product of an amine-terminated (poly)aminoamide and a mono-(meth)acrylate or a poly-(meth)acrylate. The radiation-curable composition is a liquid at room temperature and does not undergo substantial volume contraction upon curing and exhibit excellent adhesion to porous and non porous substrates alike.

Abstract: Modified soy protein adhesives are provided which have increased bonding abilities. The adhesives are prepared by forming a dispersion of soy protein, water, and a modifier selected from two classes of modifiers. The preferred modifiers are urea, sodium dodecylbenzene sulfonate, sodium dodecyl sulfate, and guanidine hydrochloride. The resulting dispersion is stirred, freeze-dried, and milled into a powder to be stored until use. The adhesives of the invention have superior bonding qualities while being safe for the environment. The urea-modified, GH-modified, SDS-modified, and SDBS-modified soy protein adhesives have higher water resistance than non-modified soy protein adhesives.
