Experimental measurement method of full tension of silk thread during winding process

The tension of fiber winding is one of the important factors in the performance of fiber. It is particularly necessary to measure the tension during the fiber winding process and to monitor the fiber tension after winding. This article adopts the method of optical fiber winding and uses OFDR (Optical Frequency Domain Reflectometry) demodulation technology to simulate fiber winding, and briefly introduces the principle of OFDR technology. Through experiments, the strain distribution of the full range of the fiber is measured. The measurement results are basically consistent with the calculation results.
