摘　　要：总结两款聚四氟乙烯长丝过滤织物的生产要点。介绍了聚四氟乙烯纤维的性能;针对用户要求,设计了织物规格,分析了生产难点;针对长丝光滑和易起静电等特性,浆纱工序以水和抗静电剂为浆料;织造工序,在储纬器和织机后部加装专用加湿装置,以减少长丝上集聚的静电。测试结果表明:生产的两款织物透气率和断裂强力均达到了用户要求。认为:生产各工序采取必要措施减少长丝上集聚的静电是生产的关键。Production key points of two PTFE filament filter fabrics were summarized.Properties of PTFE fiber were introduced.According to user′s requirements,fabric specifications were designed,production difficulties were analyzed.For smoothness and easy to start static electricity properties of filament,water and antistacic agent were used as size material in sizing process.A special humidifying device was installed at the rear of weft accumulator and loom,static electricity accumulated on the filaments was reduced.The test results showed that air permeability and breaking strength of two fabrics produced were reached user′s requirements.It is considered that taking necessary measures is the key to reduce static electricity accumulated on the filaments in production.
