在实验室对渔用共混改性中高分子量聚乙烯／聚丙烯单丝（简称共混改性MMWPE／PP单丝）和普通聚乙烯单丝（简称普通PE单丝）拉伸力学性能进行了比较试验。结果表明，共混改性MMWPE／PP单丝较普通PE单丝断裂强度提高32．3％、结节强度提高25．6％、结强损失率提高7．4％，而断裂伸长率降低47．9％。在保持断裂强力优势的前提下，以共混改性MMWPE／PP绳网替代普通PE绳网，能使远洋拖网与养殖网具用原材料降低消耗及水阻力减小，从而实现渔业生产的降耗减阻。结论可为高性能材料的选配、远洋拖网与养殖网具的优化设计提供参考。
在實驗室對漁用共混改性中高分子量聚乙烯／聚丙烯單絲（簡稱共混改性MMWPE／PP單絲）和普通聚乙烯單絲（簡稱普通PE單絲）拉伸力學性能進行瞭比較試驗。結果錶明，共混改性MMWPE／PP單絲較普通PE單絲斷裂彊度提高32．3％、結節彊度提高25．6％、結彊損失率提高7．4％，而斷裂伸長率降低47．9％。在保持斷裂彊力優勢的前提下，以共混改性MMWPE／PP繩網替代普通PE繩網，能使遠洋拖網與養殖網具用原材料降低消耗及水阻力減小，從而實現漁業生產的降耗減阻。結論可為高性能材料的選配、遠洋拖網與養殖網具的優化設計提供參攷。

The modification of mid -high molecular weight polyethylene/polypropylene monofilament for fisheries (blending modification MMWPE/PP monofilament for short) and common polyethylene monofilament (common PE monofilament for short) tensile mechanical properties were compared in the laboratory .The result shows that compared with common PE monofilament ,breaking strength and knot breaking strength of the MMWPE/PP monofilament are enhanced by 32 .3% and 25 .6% sepa‐rately .However ,loss rate of knot breaking strength and elongation at break of the MMWPE/PP mon‐ofilament separately increased 7 .4% and decreased 47 .9% .U nder the condition of keeping the advan‐tage of breaking load ,the raw material consumption of the pelagic trawl & farming netting gear as well as the resistance of netting gear in water can be reduced if the PE rope & netting is replaced by the M M WPE/PP rope & netting ,and thus the consumption decreasing and the resistance reducing in fishery can be realized .The conclusion can be used as a reference in high performance materials selec‐tion ,pelagic trawl and farming netting gear design .
