    摘要： An olefin-based resin composition contains (a) 39-94 parts by weight of a propylene homopolymer or propylene-ethylene copolymer of at least 50 wt. % propylene content, having a melt-flow rate of 0.1-5 g/10 min, (b) 1-20 parts by weight of a polypropylene modified with 0.1-10% by weight of an acid anhydride, (c) 5-60 parts by weight of a styrene-based polymeric elastomer modified with 0.1-10% by weight of an acid anhydride, the total of components (a), (b) and (c) being 100 parts by weight, and (d) 30-200 parts by weight of a metal hydroxide. This halogen-free resin composition has a good balance of properties such as wear resistance, flame resistance, tensile properties and flexibility, which are required for the covering material of an electrical wire for an automobile.

    摘要： A ten-dimensional barbed surgical thread that includes a central core and ten first barbs. The central core has a circumference, a proximal end and a distal end that is opposite the proximal end. The ten first barbs are positioned around the circumference of the central core so that the first barbs are radially adjacent to each other and obliquely extend from the central core.

    摘要： The invention relates to a filament excellent in incision resistance comprising as a primary component a polyethylene filament having a weight-average molecular weight of 300,000 or less and a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) of 4.0 or less as determined in the state of a filament as well as a modulus of 500 cN/dtex or more, and to a fabric excellent in incision resistance, a fibrous material for reinforcing cement mortar or concrete, and a rope, each of which comprises the filament. The filament can be produced by drawing a non-drawn polyolefin filament which comprises a polyethylene having a weight-average molecular weight of 60,000-600,000, a ratio of a weight-average molecular weight to a number-average molecular weight (Mw/Mn) of 4.5 or less, and a rate of birefringence (Δn) of 0.008 or more, at a temperature not higher than the α-relaxation temperature of said non-drawn filament.

    摘要： A sizing composition for reinforcement fibers that includes one or more film forming agents, a silane coupling agent package, and at least one lubricant surfactant is provided. Optional components such as rheology modifiers, fillers, biocides, and pH modifiers may also be included. Preferred film forming polymers are amide-based polymers. Additionally, the sizing composition is free of polyvinyl alcohol. The absence of polyvinyl alcohol in the size composition reduces or eliminates the production of precipitates from white water in wet-laid processes. The size composition is applied to reinforcement fibers and formed into chopped strand, wet-laid mats that can be used for a variety of purposes, including roofing products. Chopped strand mats formed from fibers sized with the inventive sizing composition maintains or improves the dry tear and tensile strengths compared to chopped strand mats made from fibers sized with a commercial sizing composition that does not contain polyvinyl alcohol.

    摘要： Described are a process for producing elastane yarn having a linear density of at least 2500 dtex by the wet spinning process and the thereby producible coarse linear density elastane yarn having a wide cross section and a low residual solvent content. The process comprises the steps of spinning an up to 35% strength by weight stable-viscosity elastane solution into a coagulation bath, washing and optionally drawing, drying by contact heating, setting, spin finishing and winding the yarn, the filaments leaving the coagulation bath passing around a diverting roller disposed just above the coagulation bath liquid, the as-spun filament linear density amounting to not more than 1% of the value of the final linear density, the jet stretch ratio being within the range from 0.5 to 50, the contact heating temperature being at least 220° C. and the contact time of the elastane yarn being at least 2 seconds.
