摘要： 由于聚合物光纤脆性大，抗弯刚度大，导致其弯曲易断裂。文章针对聚合物光纤在纬编成圈和集圈编织时容易受到损伤且不易形成织物的现象，分别测试了两种聚合物光纤的拉伸性能与弯曲性能，分析聚合物光纤力学性能对其编织性能的影响，采用直径为0.25 mm的聚合物光纤在双面圆纬机上进行成圈、集圈和浮线编织试验。探讨了辅助编织的纱线线密度，织物组织，给纱张力、弯纱深度、机速及牵拉卷取张力等编织参数对聚合物光纤纬编编织性能的影响，分析了聚合物光纤织物表面产生不平整的原因，阐述聚合物光纤在双面圆纬机上生产的编织工艺。

Abstract： Poly optical fiber is prone to bending and breakage due to the high brittleness and bending stiffness. In view that polymer optical fiber is vulnerable to damage and not easy to form fabric in weft knitted circle and tuck knitting， the tensile properties and bending performance of two types of polymer optical fiber were tested， and the influence of the mechanical properties of the polymer fiber on its knitting performance was analyzed. The knitting， tucking and float thread experiments were performed on a polymer optical fiber with the diameter of 0.25 mm using double-face circular weft knitting machine. The impact of knitting parameters such as yarn fineness， fabric weave， feeding tension， sinking depth， machine speed and pulling coiling tension on the weft knitting performance of polymer optical fiber was investigated. The causes of surface unevenness of polymer optical fiber fabric were analyzed， and the knitting process of polymer optical fiber production in double-face circular weft knitting machine was elaborated.

聚合物光纤（POF）是指用透明光学材料制成的可传导光功率的纤维[1-2]，具有成本低、柔软、质轻等优点，与石英光纤和玻璃光纤相比，聚合物光纤的柔韧性和弯曲性较好[3-4]，由其制成的光纤发光织物具有发光亮度高、质量轻和服用性能好等特点[5]，已用于机织物和针织物的加工。聚合物光纤在机织物中以平直状态出现，受到的損伤较小，织造较为简单[6-7]。但聚合物光纤作为成圈纱线编织时，由于脆性大、抗弯刚度大的特性在编织过程中易受损断裂，给针织加工带来较大的困难，因此一般作为不成圈的衬纬纱线出现在针织物中。匡丽赟等[8]在手摇横上编织聚合物光纤，光纤衬入织物中形成具有不同纹样效果的光纤发光织物。……
