Disclosed is a polytrimethylene terephtalate conjugate fiber having high self-crimpability, which is prepared by conjugate-spinning two types of polytrimethylene terephtalates having different intrinsic viscosities in which a difference between the intrinsic viscosities ranges from 0.05 to 0.15 into a side-by-side fiber. Also, the polytrimethylene terephtalate conjugate fiber prepared by the conjugate-spinning undergoes a false twisting process, leading to development of three-dimensional high self crimpability and sufficient bulky property in the resulting fiber.

The invention discloses an outdoor sport fabric. The outdoor sport fabric is interwoven by warp yarns and weft yarns. The outdoor sport fabric is characterized in that the warp yarns are 75D / 72F polyester low-stretch moisture-absorption sweat-discharging fibers; two weft yarns are available in the fabric; weft yarns A are 150D / 64F PET / PTT (Polyethylene Terephthalate / Polytrimethylene Terephthalate) composite elastic fibers; the weft yarns B are 32S / 1 tencel fibers; the weft face is adopted as the fabric of the front face of the fabric; weft yarns float at the front face of the fabric; and warp yarns float at the back face of the fabric. The outdoor sport fabric has the advantages of simple and reasonable structure, good cloth surface color uniformity, clear lines, full particles, strong three-dimensional sense, good moisture absorption, softness, comfort, smooth tencel fibers, good drapability and antistatic performances and is an ideal outdoor sport fabric.

The invention discloses an environment-friendly plastic material and a preparation method thereof. The preparation method comprises the following steps that 1, ball milling is performed on calcium sulfate and magnesium oxide through a ball mill, the ball milling time is 3-5 h, and the ratio of grinding media to the materials is 20:1-30:1; 2, 12-20 parts of polyamide-1010, 5-10 parts of polycarbonate, 4-9 parts of alkyd resin, 4-8 parts of polyvinyl alcohol, 3-8 parts of calcium sulfate, 4-10 parts of magnesium oxide, 2-6 parts of polytrimethylene terephthalate, 3-8 parts of tetrafluoroethylene-hexafluoropropylene copolymer, 2-6 parts of polybutyl methacrylate and 4-10 parts of polyparahydroxybenzoic acid are weighed by weight, all the components are extruded inside a double-screw extruder, and the extruded components are the environment-friendly plastic material. The obtained plastic material effectively overcomes the defects that the tensile strength and the elongation at break of the conventional plastic material are low, and the mechanical performance of the plastic material is improved.
