  • Patent number: 9770876
    Abstract: In a method of manufacturing an object, a filament is fed to an extrusion head. The filament has a semi-crystalline polymeric reinforcement portion and a polymeric matrix portion. The temperature of the filament is raised in the extrusion head above the melting point of the matrix portion but below the melting point of the reinforcement portion so that the matrix portion of the filament melts within the extrusion head, thereby forming a partially molten filament within the extrusion head. The reinforcement portion of the partially molten filament remains in a semi-crystalline state as it is extruded from the extrusion head. Relative movement is generated between the extrusion head and the substrate as the partially molten filament is extruded onto the substrate in order to form an extruded line on the substrate. The matrix portion of the extruded line solidifies after the extruded line has been formed on the substrate.

  • Patent number: 9085833
    Abstract: A polyester monofilament comprising a high-viscosity polyester as a core component and a low-viscosity polyester as a sheath component is provided, the polyesters having been combined together in a core-sheath arrangement. The polyester monofilament has a fineness of 3.0-13.0 dtex, a breaking strength of 6.0-9.3 cN/dtex, a strength at 10% elongation of 5.0-9.0 cN/dtex, a difference in wet heat stress in the filament-length direction of 3.0 cN or less, and a residual torque value of at most 4 turns per m. Provided is a process for producing a polyester monofilament by a direct spinning/drawing method in which two ingredients, i.e., a high-viscosity polyester as a core component and a low-viscosity polyester as a sheath component, are melt-extruded from a spinnert while being combined together in a core-sheath arrangement, and cooled and solidified, and the resultant extrudate filament is continuously drawn and wound up.

  • Publication number: 20150132574
    Abstract: A fiber is provided with a polymer having a cross-section and a length. A particulate is distributed in the polymer in an amount to make the fiber detectable by X-ray detection or magnetic detection. The particulate is present in a core, a sheath, or both portions of polymer matrix. A process of detecting a fabric article is provided that includes the formation of a fiber in the form of a polymer having a cross-section and a length. A particulate is distributed in the polymer. A fiber is formed into a fabric. A fabric article is then manufactured from the fabric. The fabric article passes through an X-ray detector or a magnetic detector. A signal is collected from the X-ray detector or the magnetic detector indicative of the presence of the fabric article.
