摘要：
Process for removing residual spin solvent from a gel spun, UHMwPE filament having an effective diameter of above 16 μm, comprising the steps of: removing residual spin solvent from the filament to a level of below 100 ppm at elevated temperature, while keeping the filament taut. The invention also relates to gel spun UHMwPE filament having an effective diameter of above 16 μm and a residual spin solvent residue of less than 100 ppm. Preferably the filament has a creep rate, measured at 5O °C, under a load, so that the initial stress is 600 MPa, of less than 5⋅10-6 sec-1.
