Study on the performance of a new type of bobbin silk reeling machine

This study mainly investigated the performance and process parameter optimization of a new type of bobbin silk reeling machine by using orthogonal analysis designs. This new type of bobbin silk reeling machine with advanced winding and tension control technology was built through the transformation of a traditional automatic reeling machine. Experimental results indicated that a reeling speed of 130 m/min, an overfeeding ratio of 1.15, and a drying temperature of 90°C were the optimal process parameters. The molecular group characteristics, crystal structures, breaking strengths, and breaking elongation rates of the raw silk from homemade silk slices on bobbins prepared by this machine were similar to those from silk slices on small reels prepared by automatic silk reeling machines and traditional silk slices on bobbins prepared by winders. The softness of the raw silk from homemade silk slices on bobbins was similar to that from traditional silk slices on bobbins, and the cohesion performance of the raw silk from homemade silk slices on bobbins was better than that from traditional silk slices on bobbins. The raw silk from homemade silk slices on bobbins prepared by this machine is directly suitable for postweaving processing. This study can provide a practical basis for the development of the raw silk reeling technique on bobbins.
