  • Publication number: 20120225248
    Abstract: The present invention relates to an artificial leather having composite fibers and a method for making the same. The artificial leather includes a substrate and a flexible film. The substrate includes a plurality of composite fibers. Each composite fiber includes a first composition and a second composition. The first composition is a thermoplastic non-elastomer, and the second composition is a thermoplastic elastomer. The second composition accounts for 5% to 70% of the total weight of the composite fiber. The second composition at the intersecting points between the composite fibers is molten to form a flexible bonding point. The flexible film is located on a surface of the substrate, and the material of the flexible film is an elastic polymer or a latex. Therefore, the artificial leather has excellent textile sensation and physical properties.

  • Publication number: 20100041294
    Abstract: A core-sheath fiber has a core and a sheath. The core comprises 0.1 to 10 wt % of carbon black pigment particles. The sheath surrounds the core preventing the core from being exposed. Because the carbon black pigment particles are mainly distributed in the core and the core is surrounded by the sheath with little or no carbon black pigment particles, a surface of the core-sheath fiber has low friction and electrical conductivity. Therefore, a lifetime of a punch needle used in machinery to produce a nonwoven is maintained and the nonwoven can undergo high frequency treatment to form artificial leather. Additionally, the sheath has little or no carbon black pigment particles, so the sheath is improved compatibility with polyurethane (PU) used for high frequency treatment.
