20090088039 | Process for Producing a Sound-Insulation Part - A method for producing a noise insulation piece of mass/spring construction. The mass has, at least before a deep draw process, at least one locally defined region, with a different weight per area from the other regions. After the deep draw process, the spring layer made from an elastic light material such as two-component polyurethane foam or a mixed non-woven fiber is applied. The locally different weight per area of the mass is achieved by means of application of a granulate to a base mass layer in particular in locally differing amounts and/or thicknesses, wherein the granulate is fixed to itself and to the base mass layer by means of sintering. After deep drawing, the desired weight per area of the mass can be achieved independent of the degree of drawing. The granulate can alternatively also be applied to a thin and lightweight support layer in locally required amounts or thicknesses. | 04-02-2009 |
20090104831 | POLYMER FIBER AND NONWOVEN - A polymer fiber comprising a thermoplastic polymer and an inorganic filler, wherein the filler content, based on the polymer fiber, is more than about 10% by weight and the mean particle size (D | 04-23-2009 |
20090156080 | Binder composition - A binder composition comprising an emulsion copolymer, and a polyol crosslinker. | 06-18-2009 |
20090215345 | PARTICLE-CONTAINING FIBROUS WEB - A porous sheet article comprising a self-supporting nonwoven web of polymeric fibers and at least 80 weight percent sorbent particles enmeshed in the web, the fibers having sufficiently greater elasticity or sufficiently greater crystallization shrinkage than similar caliper polypropylene fibers and the sorbent particles being sufficiently evenly distributed in the web so that the web has an Adsorption Factor A of at least 1.6×10 | 08-27-2009 |
20100184348 | Spunlaid Fibers Comprising Coated Calcium Carbonate, Processes For Their Production, and Nonwoven Products - Disclosed herein, in one embodiment, are spunlaid fibers comprising at least one polymeric resin and at least one filler having an average particle size of less than or equal to about 5 microns and/or having a top cut of less than about 15 microns, wherein the at least one filler is present in an amount of less than about 40% by weight, relative to the total weight of the spunlaid fibers. Also disclosed herein is a method for producing spunlaid fibers comprising adding calcium carbonate to at least one polymeric resin and extruding the resulting mixture. Further disclosed herein are nonwoven fabrics comprising such spunlaid fibers and methods for producing them. | 07-22-2010 |
20120064792 | Water Absorbent Storage Layers - The present invention relates to improved water-absorbing storage layers for use in hygiene articles, the water-absorbing storage layers being essentially free of cellulose fibers. | 03-15-2012 |
20120238175 | SPUNLAID FIBERS COMPRISING COATED CALCIUM CARBONATE, PROCESSES FOR THEIR PRODUCTION, AND NONWOVEN PRODUCTS - Disclosed herein are spunlaid fibers comprising at least one polymeric resin and at least one filler having an average particle size of less than or equal to about 5 microns and/or having a top cut of less than about 15 microns, wherein the at least one filler is present in an amount of less than about 40% by weight, relative to the total weight of the spunlaid fibers. Also disclosed herein is a method for producing spunlaid fibers comprising adding calcium carbonate to at least one polymeric resin and extruding the resulting mixture. Further disclosed herein are nonwoven fabrics comprising such spunlaid fibers and methods for producing them. | 09-20-2012 |
