A polyolefin polymer which is suitable for forming fibres is mixed with a first additive capable of modifying a surface property and capable of migration through the polymer, then the mixture is used for producing at least one layer of the nonwoven textile by a spun-melt process, and prior to the termination of the migration of the first additive and to the stabilizing of the final barrier properties on the surface of the fibers a second additive is applied to the layer, the second additive being capable of modifying the antistatic property of the material, and then the nonwoven textile is exposed to a temperature and relative humidity conditions for a time period such that the first additive migrates towards the surface and the second additive undergoes changes on said surface. | 05-09-2013 |
| 20130130584 | PREPREG, FIBER-REINFORCED COMPOSITE MATERIAL, AND PROCESS FOR PRODUCING PREPREG - There is provided a prepreg which contains components (A) to (C) as mentioned below, wherein the component (A) is arranged on one surface or both surfaces of a layer comprising the components (B) and (C): (A) a nonwoven fabric comprising a thermoplastic elastomer and/or a polyolefin each of which has a value of tan θ of 0.06 or more at 10° C. as measured in a viscoelasticity measurement and is incompatible with the component (B); (B) a first epoxy resin composition; and (C) a reinforcing fiber. There are also provided a fiber-reinforced composite material which has excellent rigidity, strength, and vibration-damping performance, a prepreg which can be used suitably for the production of the fiber-reinforced composite material, and a process for producing the prepreg. | 05-23-2013 |
| 20130280979 | FIBROUS ELEMENTS COMPRISING A NON-HYDROXYL POLYMER AND METHODS FOR MAKING SAME - Fibrous elements, such as filaments and/or fibers, and more particularly to fibrous elements that contain a non-hydroxyl polymer, fibrous structures made therefrom, and methods for making same are provided. | 10-24-2013 |
| 20130303043 | POLYMER COMPOSITION AND MOLDED PRODUCTS FORMED THEREOF - The present invention provides a polymer composition including a first base polymer (A) containing at least a thermoplastic polymer, a second base polymer (B) containing at least a thermoplastic polymer and not having compatibility with the first base polymer (A), and an additive (C) containing at least a substance not having compatibility with any of the first base polymer (A) and the second base polymer (B), the additive (C) being in the form of liquid or slurry at the lower of a pyrolysis temperature of the first base polymer (A) and a pyrolysis temperature of the second base polymer (B). (A), (B) and (C) are phase-separated from each other, and interfaces each located between two of phases of (A), (B) and (C) contacting each other form three-dimensional continuous parallel interfaces. | 11-14-2013 |
| 20160052229 | VEILED TAPE WITH IMPROVED RESISTANCE TO DELAMINATION - The present invention provides a tape with a given width, said tape being composed of an assembly of filaments extending in a direction substantially parallel to the length of the tape, and between which a powder of a polymeric material is distributed, each face of said tape being associated with a nonwoven of polymeric fibers. | 02-25-2016 |

| 20120115388 | COMPATIBLE CARRIER FOR SECONDARY TOUGHENING - Embodiments of the invention are directed to carriers providing a primary toughening function and incorporating a secondary toughening agent therein. According to embodiments of the invention, the carrier/agent combination may be used in liquid resin infusion applications. The carrier may be any polymer-based material having a solubility characteristic in a thermosetting resin. The secondary toughening agent may be of a material such as a thermoplastic, a thermoset, a cross-linked thermoset, a rubber, a rubbery-like material or a combination thereof and may be in the form of a particle, a micro-fiber (fibril) or a fibrous network. In some embodiments, the carrier is soluble in the resin while the secondary toughening agent is insoluble in the resin when subjected to a cure cycle. | 05-10-2012 |
