The present invention relates to the use of an amine compound comprising at least one, preferably at least two amine functions, wherein the amine functions are primary or secondary amines, to reduce the level of furfural and/or hydroxymethylfurfural in a carbohydrate-based binder or binder composition and/or escaping in the course of preparation, cross-linking and/or curing of carbohydrate-based binders. Preferably, the carbohydrate-based binder is obtained from a carbohydrate-based binder composition comprising a carbohydrate component and a cross-linker and possibly reaction product of carbohydrate component and cross-linker, wherein the cross-linker is selected from ammonium salts of inorganic acid, carboxylic acids, salts, ester or anhydride derivatives thereof, and/or combinations thereof.

A textile recycling method receives textile-waste-to-be-recycled, sorts the waste to isolate cellulose-containing articles from non-cellulose-containing articles, and re-sizes at least some of the cellulose-containing articles to create feedstock. The feedstock is processed in a cellulose solvent reactor, which has at least one ionic liquid. The ionic liquid dissolves intermolecular cellulose bonds of the feedstock to create a spinning dope. Cellulose fibers dissolved in the cellulose-bearing spinning dope solution are extruded in a cellulose coagulation bath reservoir to reconstitute at least some of the cellulose fibers, and the reconstituted fibers are wet-spun to form a continuous cellulose thread that is commercially indistinguishable from virgin fiber thread. Synthetic fiber material is vacuum-extracted or mechanically extracted from the cellulose-bearing solution and recycled into a continuous synthetic thread. Original color of textile-waste-to-be-recycled can be retained or removed, and new color can be added.

A scrubbing article including a substrate and a texture layer. The texture layer is formed on at least one surface of the substrate, and is a solvent-free texture layer. The texture layer can include a plastisol ink or a hot melt adhesive, and may further include a plurality of ceramic microspheres. Methods of manufacture are also provided in which a solvent-free texture layer composition is applied to a substrate and then solidified to form a texture layer. In some non-limiting embodiments, the texture layer composition includes a hot melt adhesive and is applied to the substrate in the form of a wetted cellulose sponge.

Disclosed is a porous structure including water-soluble chitosan; and a carboxymethyl cellulose-based compound, wherein a weight ratio of the water-soluble chitosan and the carboxymethyl cellulose-based compound is from 65:35 to 25:75, and a process for preparing the same.

The present invention provides a method of producing a polymer hydrogel comprising the steps of: (1) preparing an aqueous solution of a water soluble polysaccharide derivative and a polycarboxylic acid; (2) optionally agitating the solution, for example, by stirring; (3) isolating a polysaccharide derivative/polycarboxylic acid composite from the solution; and (4) heating the polysaccharide derivative/polycarboxylic acid composite at a temperature of at least about 80° C., thereby cross-linking the polysaccharide with the polycarboxylic acid. The invention also provides polymer hydrogels produced by the methods of the invention.

The present invention relates to a gluten-free alimentary composition which comprises extruded babassu flour. It also relates to an alimentary ingredient and to an alimentary film which comprises said babassu flour. The present invention also relates to a procedure for preparing an extruded babassu flour-based alimentary composition and to a procedure for preparing an alimentary film which comprises said flour. Likewise, an alimentary protective coating is also provided which comprises said alimentary composition and/or a packaging for said film and the procedures for their preparation.

A method for producing customized object is provided. A resin (e.g. plastic or cellulose) is heated and a quaternary salt is added. The resulting admixture is used in forming a material that embodies customized characteristics. In another embodiment, a halogen-containing polymer has a quaternary molecule covalently bonded to it that results in customized properties.

The present invention provides a cellulose powder containing an alkali-soluble substance capable of dissolving in 17.5% by mass of aqueous sodium hydroxide solution, the content of the alkali-soluble substance being 32% by mass or more and 44% by mass or less with respect to the total mass of the cellulose powder, the use thereof, and tablets using the same.
