Definitions

• a method of preparing a high strength, high modulus polyethylene (PE) fiber from UHMWPE gel via drawing or stretching technology is disclosed in UK Patent Nos. GB2042414 and GB2051667, assigned to DSM Company, Netherlands in 1979. After that, this technology was industrialized by Allied Company from the U.S., Toyobo-DSM Company, a joint venture by Japan and Netherlands, as well as Mitsui Company from Japan. In 1982, Allied Company obtained U.S. Pat. No. 4,413,110, which covers a process of preparing UHMWPE fiber. Donghua University in China also obtained Chinese Patent Nos. 89107905 and 97106768 in this area.
• the PE powder having a relative MW of 1 million to 6 million is mixed with polar polymer and solvent in an appropriate ratio, and the resulting mixture is fed into an untwisting equipment to untwist, and thereby forming a uniform emulsion mixture.
• the solvent used is liquid under room temperature, and it may be alkane (or paraffin) or its derivative, cycloalkane (or cycloparaffin) or its derivative, aromatic hydrocarbon or its derivative, or mixtures thereof.
• UHMWPE Relative Average Molecule Weight 4.5M powder and #90 solvent white oil with a weight ratio of 1:8, were fed into an untwisting pan at room temperature, and underwent cutting for 10 minutes at a speed of 2000 S ⁇ 1 under N 2 protection, to form a homogeneous emulsion mixture.
• the extruded material was filtered, and spun into a gel filament through a spinnerette, then extracted and stretched at a stretch ratio of 35, to provide UHMWPE.
• UHMWPE Relative Average Molecule Weight 4.5M powder
• the extruded material was filtered, and spun into a gel filament through a spinnerette, then extracted and stretched at a draw ratio of 35, to produce UHMWPE with high adhesive properties.
• UHMWPE (Relative Average Molecule Weight 4.5M) powder and #90 solvent white oil with weight ratio of 1:8 were fed into an untwisting pan at room temperature, and further added polyoxyethylene with an amount of 4% by weight of the UHMWPE powder, and underwent cutting for 10 minutes under N 2 protection at a speed of 2000 S ⁇ 1 , to form a homogeneous emulsion mixture.
• the extruded material was filtered, and spun into a gel filament through a spinnerette, then extracted and stretched at a draw ratio of 35, to produce UHMWPE with high adhesive properties.
• UHMWPE (Relative Average Molecule Weight 4.5M) powder and #90 solvent white oil with a nominal concentration of 10% (wt) were fed into an untwisting pan at room temperature, and underwent cutting for 5 minutes under N 2 protection at a speed of 3000 S ⁇ 1 , to form a homogeneous emulsion mixture.
• UHMWPE (Relative Average Molecule Weight 4.5 M) powder and #70 solvent white oil with a nominal concentration of 10% (wt) were fed into an untwisting pan at room temperature, and further added 1% (wt) of epoxy modified silicone oil, and underwent cutting for 5 minutes under N 2 protection at a speed of 3000 S ⁇ 1 , to form a homogeneous emulsion mixture.
• the extruded material was passed through a filter tank and a metering pump to get a measurement, and spun into a gel filament through a spinnerette, passed through a water bath containing 1.5wt % of epoxy modified silicone oil, followed by extraction, drying and stretching at a draw ratio of 40, to produce UHMWPE fiber with Rupture Strength of 35 cN/dtex and Young's Modulus of over 1050 cN/dtex.
