    • The invention relates to a process for making high-performance polyethylene multi-filament yarn comprising the steps of making a solution of ultra-high molar mass polyethylene in a solvent; spinning of the solution through a spinplate containing a plurality of spinholes into an air-gap to form fluid filaments, while applying a draw ratio DR fluid;cooling the fluid filaments to form solvent- containing gel filaments; removing at least partly the solvent from the filaments; and drawing the filaments in at least one step before, during and/or after said solvent removing, while applying a draw ratio DR solid,wherein in a draw ratio DRfluid = DR sp x DRag of at least 50 is applied, wherein DRsp is the draw ratio in the spinholes and DRag is the draw ratio in the air-gap, with DRsp greater than 1 and DRag at least 1. The invention further relates to a spinplate having spinholes of specific geometry.
    • 本发明涉及一种制备高性能聚乙烯复丝纱线的方法,包括以下步骤:将超高摩尔质量的聚乙烯溶液溶解在溶剂中; 同时施加拉伸比DR流体;冷却流体细丝以形成含溶剂的凝胶细丝;将溶液通过包含多个喷孔的平板旋转到气隙中以形成流体细丝; 从长丝中至少部分去除溶剂; 并且在施加拉伸比DR固体之前,期间和/或之后将所述长丝拉伸至所述溶剂除去之前,期间和/或之后,其中应用拉伸比DRfluid = DR sp×DRag至少为50,其中DRsp为 喷孔中的拉伸比和DRag是气隙中的拉伸比,其中DRSP大于1,并且DRag至少为1.本发明还涉及具有特定几何形状的孔的平板。
