Abstract: Processes for removing residual spin solvent from a gel spun, UHMwPE filament having an effective diameter of above 16 μm, comprise 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. Gel spun UHMwPE filaments having an effective diameter of above 16 μm and a residual spin solvent residue of less than 100 ppm are also provided. Preferably the filament has a creep rate, measured at 50° C., under a load, so that the initial stress is 600 MPa, of less than 5·10−6 sec−1.

Abstract translation: 从有效直径大于16μm的凝胶纺丝UHMwPE细丝中除去残余旋转溶剂的方法包括以下步骤：在保持丝束拉伸的同时，将长丝上残留的旋转溶剂从升高的温度下除去至低于100ppm的水平。 也提供了有效直径高于16μm的凝胶纺丝UHMwPE细丝和小于100ppm的残留旋转溶剂残余物。 优选地，长丝在负荷下在50℃下测得蠕变速率，使得初始应力为600MPa，小于5×10 -6秒-1。
