    摘要: The present invention discloses an ultra-high molecular weight polyethylene (UHMWPE)/inorganic nanocomposite material and a high performance fiber manufacturing method using UHMWPE and a dispersed inorganic nano substance (such as attapulgite, carbon nano-tube, sepiolite, wollastonite and montmorillonite) to prepare a gel solution. The gel solution having a light transmittance approaching zero at a certain concentration is heated, dissolved and gone through processes including vacuum debubbling, sudden air cooling, water-phase solidification, and multi-stage temperature-change drawing for a spinning by using different conditions of a spinneret (including different spinneret angles, in-feed lengths and out-feed lengths) to obtain a composite material composed of high-tenacity fibers and having a light transmittance approaching to zero, so as to increase the fiber strength and modulus of the UHMWPE and overcome the drawbacks of high crimp, creep, and light transmission of the high molecular weight polyethylene fiber.
