| 渔用高强度聚乙烯编织线（以下简称HSPE编织线）和普通聚乙烯编织线（以下简称PE编织线）的拉伸力学性能比较试验结果表明，在同等编线工艺（编织线捻距为27 mm、线股结构为3×16、线芯用丝数量为7和线芯为不加捻的平行丝束）条件下，规格为“HSPE－37tex×3×16＋7”HSPE编织线断裂强力、单线结强力分别比规格为“PE－37tex×3×16＋7”PE编织线增加了10.0%和9.1%，而前者的断裂伸长率比后者减少了11.3%；在同等编线工艺（编织线捻距为30 mm、线股结构为4×16、线芯用丝数量为18和线芯为不加捻的平行丝束）条件下，规格为“HSPE－37tex×4×16＋18”HSPE编织线断裂强力、单线结强力分别比规格为“PE－37tex×4×16＋18”PE编织线增加了8.1%、6.1%，而前者的断裂伸长率比后者减少了13.3%；HSPE编织线较PE编织线具有强力优势，HSPE编织线在渔具或网箱上推广应用具有可行性。 |

| Comparisons between tensile mechanical properties of high strength polyethylene braided netting twine (HSPE braided netting twine) and common polyethylene braided netting twine (PE braided netting twine) for fishing have been made by applying the SC 5005 fisheries trade standard and SC 110 fisheries trade standard.The results revealed that under the same condition(the pitch of twist of twine was 27 mm, the structure of strand was 3×16,the twine core was a parallel thread which was made from 7 monofilaments without twining), the HSPE braided netting twine（whose specification was HSPE－37tex×3×16＋7）was 10.0% and 9.1% higher than common polyethylene braided netting twine (PE braided netting twine PE－37tex×3×16＋7) in breaking strength and overhand knot strength, respectively, while in percentage of breaking elongation, the former was 11.3% smaller than the latter Under the same condition(the pitch of twist of twine was 30 mm, the structure of strand was 4×16,the twine core was a parallel thread which was made from 18 monofilaments without twining), the HSPE braided netting twine（HSPE－37tex×4×16＋18）was 8.1% and 6.1% higher than common polyethylene braided netting twine (PE braided netting twine, PE－37tex×4×16＋18）) in breaking strength and overhand knot strength, respectively, while in percentage of breaking elongation, the former was 13.3% smaller than the latter. Under the prerequisite of strength of braided netting twine, the HSPE braided netting twine, if used in fishing gear or fish cage, is more feasible than the same structure PE braided netting twine. |
