bobbin(名词):梭芯;线轴。用于缝纫机、纺织或编织等,把线绕在上面,供机器或手工顺畅放线使用。(在某些语境中也可泛指小线轴。)
/ˈbɑːbɪn/
I ran out of thread and had to replace the bobbin.
我把线用完了,只好更换梭芯。
As the machine sped up, the bobbin fed the lower thread evenly, keeping the stitches neat and strong.
随着机器加速,梭芯均匀送出底线,使针脚整齐结实。
bobbin 可能来自法语方言词(与“小球、线团”之类的概念相关),早期用于指纺织时绕线用的小卷轴或线团。后来在工业与家用缝纫机普及后,词义固定为“缝纫机梭芯/线轴”。
