Abstract: A sorbent glass fiber material is useful for sorbing spills of water and water-soluble liquids. The sorbent material includes glass fibers combined with hydrophilic absorbent particles. The particles may be made from polymers having hydrophilic groups such as crosslinked polyacrylamide, crosslinked sulfonated polystyrene, crosslinked polyacrylate, crosslinked polymethacrylates, crosslinked copolymers of acrylates and methacrylates, and mixtures thereof. The glass fibers may be bindered (e.g., batting insulation) or unbindered (e.g., loose-fill blown wool insulation).

Abstract: Permanently crimped fibres produced by three-dimensional texturing, and a method for making same, are disclosed. The fibres are advantageously produced by spinning and optionally stretching a filament roving. The roving is then fed to a three-dimensional texturing station then to a cutting device for cutting the roving into fibres having a predetermined length. The resulting fibres have high bulkiness and enable the production of non-woven surfaces having a remarkable abrasiveness as well as carpets with enhanced wear properties.

Abstract: A biodegradable hydrophilic binder fiber. These fibers may be produced by co-spinning a high-melting aliphatic polyester core material with a highly wettable aliphatic polyester blend. The highly wettable aliphatic polyester blend comprises an unreacted mixture of an aliphatic polyester polymer selected from the group consisting of a polybutylene succinate polymer, a polybutylene succinate-co-adipate polymer, a polycaprolactone polymer, a mixture of such polymers, or a copolymer of such polymers; a multicarboxylic acid; and a wetting agent. The biodegradable hydrophilic binder fiber exhibits substantial biodegradable properties, yet is easily processed. The biodegradable hydrophilic binder fiber may be used in a disposable absorbent product intended for the absorption of fluids such as body fluids.

Abstract: Cellulosic fibers made from a solution of cellulose in a tertiary amine oxide and optionally water and which have a low tendency to fibrillate are produced by coagulating the fibers in at least two stages. The residence time of the fibers in the first coagulation stage is adjusted so that on leaving the first coagulation stage only the adhesiveness of the surface of the solution formed into fibers has been counteracted. In subsequent coagulation stages, the fibers are kept in a slack state. On leaving the final coagulation stage, the fibers have been thoroughly coagulated. The cellulosic fibers have a new structure and apart from a very low tendency to fibrillate, they possess a high dyeing level.

Abstract: The invention concerns polyester filaments and method for manufacturing same. More particularly it concerns a filament made of glycol ethylene polyterephtalate or polynaphtalate having high mechanical properties, and a method for stretching polyester filaments. It is obtained by a stretching process comprising two steps including a first step in which a low stretching ratio is applied, to cause minimal crystallization of the polymer and, a second step with a high stretching ratio. The global stretching ratio can reach values higher than 12. The filament has in particular an expanded elastic range that enables the improvement of its useful properties, for instance for manufacturing screen printing grids.

Abstract: Process for the production of polypropylene fibers from polypropylene polymers produced by the polymerization of polypropylene in the presence of a metallocene catalyst characterized by a bridged racemic bis(indenyl) ligand substituted at the proximal position. The polypropylene contains 0.5 to 2% 2,1 insertions and has an isotacticity of at least 95% meso diads and is heated to a molten state and extruded to form a fiber preform. The preform is subjected to spinning at a spinning speed of at least 500 meters per minutes and subsequent drawing at a speed of at least 1,500 meters per minute to provide a draw ratio of at least 3 to produce a continuous polypropylene fiber. The draw speed and/or the draw ratio can be varied to produce fibers of different mechanical properties. Different polypropylene polymers produced by different metallocene catalysts can be used. Such fibers can be characterized by having an elongation at break of at least 100% and a specific toughness of at least 0.5 grams per denier.
