摘要： One or more embodiments of the present disclosure relate to a core-sheath conjugate fiber for artificial hair including a core and a sheath. The core is composed of a polyester-based resin composition containing a polyester-based resin as a main component, and the sheath is composed of a polyamide-based resin composition containing a polyamide-based resin as a main component. The sheath contains at least one organic pigment selected from the group consisting of (a) a nickel complex pigment in which nickel and an organic dye structure are in a coordinate bond at a ratio of 1:1 or 1:2, (b) a chromium complex pigment in which chromium and an organic dye structure are in a coordinate bond at a ratio of 1:1 or 1:2, and (c) an organic pigment that contains no metal and contains a nitro group. The core contains a pigment that is different from that of the sheath. As a result, core-sheath conjugate fibers for artificial hair having a texture that is similar to that of human hair and having favorable coloring properties and spinnability, hair ornaments including the core-sheath conjugate fibers for artificial hair, and a method for producing the core-sheath conjugate fibers for artificial hair are provided.

摘要： Various aspects disclosed relate to structure such as a textile, a garment, a garment component, footwear, or a footwear component. The present disclosure includes the structure having a first region having one of more first fibers. An individual first fiber includes co-extruded first and second filaments, the first filament formed of a first thermoplastic polymeric material. Due to expansion or contraction of the one or more first fibers, the first region contracts or expands on a change in relative humidity, relative to an equilibrium state of the first region prior to the change in relative humidity.

摘要： Resorbable multifilament yarns and monofilament fibers including poly-4-hydroxybutyrate and copolymers thereof with high tenacity or high tensile strength have been developed. The yarns and fibers are produced by cold drawing the multifilament yarns and monofilament fibers before hot drawing the yarns and fibers under tension at temperatures above the melt temperature of the polymer or copolymer. These yarns and fibers have prolonged strength retention in vivo making them suitable for soft tissue repairs where high strength and strength retention is required. The multifilament yarns have tenacities higher than 8.1 grams per denier, and in vivo, retain at least 65% of their initial strength at 2 weeks. The monofilament fibers retain at least 50% of their initial strength at 4 weeks in vivo. The monofilament fibers have tensile strengths higher than 500 MPa. These yarns and fibers may be used to make various medical devices for various applications.
