Abstract:

In order to study the influence of the fabric structure change of the warp-knitted optical fiber sensing fabric on the bending loss of the optical fiber inlaid during longitudinal stretching, a warp-knitted fiber sensing fabric with a locknit construction as the ground structure and an polymer optical fiber as the inlay yarn was knitted. A section of polymer optical fiber was inlaid into the ground structure in a form of two reverse connected semicircles with a radius of 10 mm, forming a sensing unit. Stitch height, stitch width and fabric thickness under tensile loading were measured, and the signal transmission property of the optical fiber was tested. Experiment results show that the optical fiber can be combined with warp-knitted fabric in the form of weft insertion. During stretching process, yarn sections of the ground structure are transferred and fabric thickness decreases with the increase of the stretching distance. The pressing effect of the knitting yarns on the optical fiber causes the micro-bending loss of the optical fibers, and the microbending and macrobending losses are compounded during stretching process.

Key words: warp knitting, polymer optical fiber, sensing fabric, macrobending, loss
