What’s New in Sewing

What’s new in sewing? Lots. Here are two newly-published gobs of research info.

Parameters of the Bobbin

“Influence of the parameters of the bobbin on the friction between the unwinding thread and the plastic sticks of the rubber bushing in the sewing machine,” M.A. Mansurova; Z.S. Vafaeva; J.B. Matyaqubova, Proceedings of the III International Conference on Advances in Science, Engineering, and Digital Education: ASEDU-III 2022, 8–10 December 2022 Krasnoyarsk, Russian Federation, AIP Conference Proceedings, vol. 2969, 060019, 2024.

The authors report:
“The article provides a structural diagram and the principle of operation of a composite bobbin with an elastic sleeve and plastic sticks. An analytical method is given for determining the moment of friction between the unwinding thread and the plastic sticks of the rubber bushing in the sewing machine, based on the analysis of the constructed graphical dependencies, the main parameters of the recommended bobbin design in the sewing machine.”

impact of the tension force of needle thread

“Analysis of impact of the tension force of needle thread on the shift of the axis of cushioning bush of the composite roller of thread guide in sewing machine,” G. Tursunova and A. Djuraev, Proceedings of the III International Conference on Advances in Science, Engineering, and Digital Education: ASEDU-III 2022, 8–10 December 2022 Krasnoyarsk, Russian Federation, AIP Conference Proceedings, vol. 2969, no. 1, 2024.

The authors report: “The article covers the structural features of thread guides of technological machines. The schematic diagram of recommended construction of thread guide with composite roller with cushioning rubber bush is given. The results of theoretical research on determination of shift of the axis of cushioning bush of the composite roller of thread guide in a sewing machine are given. Parameters of the thread guide are substantiated.”
