摘　　要：基于石英光纤针织编织性能的探讨,对石英光纤的力学性能进行测试与分析,主要包括打结强度和钩接强度。结合石英光纤强度低、弯曲性能差、易脆断等性能特点,在手摇横机上将光纤作为衬纬纱编织衬纬针织物,并分析讨论不同弯曲半径、织物弯曲和拉伸对光纤损耗的影响。结果表明,光纤的损耗随弯曲半径的增加呈下降趋势,织物在拉伸和弯曲的过程中,纬向拉伸时光纤的损耗较大。石英光纤编织性能的研究为光纤传感产品的开发提供了依据。In order to discuss the knitting property of silica optical fiber, the basic mechanical properties of the silica optical fiber such as knot strength and loop strength are tested. In view of the low strength, poor bending property and easy broken properties of silica optical fiber, several inlay fabrics are knitted with the laid-in yarn of silica optical fiber, and the influences of bending curvatures and properties of optical fiber and resultant fabric on the transmission loss are analyzed. The results show that the transmission loss of optical fiber descends with the in- crease of bending radius, which is larger when stretching in the weft direction than in warp direction. It provides a reference for the development of fiber optical sensing products.
