During hollow spindle spinning, the yarn package rotates at a high speed, yarn untwists from the package and forms a balloon. The yarn balloon phenomenon exists commonly in spinning processes. The shape of yarn balloon is a general displacement of the forces acts on the balloon yarn. There is a close relationship between the yarn balloon shape and the forces acts on the balloon. The balloon shape is decided by the spinning force, on the contrary, we can find the value of the spinning force according to the yarn balloon shape. To a great extent, the spinning tension impacts the yarn structure and quality.

空心锭子纺纱过程中，纱线卷装随锭子高速转动并退绕，因而产生了气圈现象，气圈是纺纱过程中比较普遍的现象，气圈的形态是纺纱过程中气圈纱线受力的综合体现，纱线张力与气圈形态密切相关，纱线张力决定了气圈形态，反之则可根据气圈形态算出纱线张力，纺纱张力在很大程度上会影响成纱的结构和质量，而纺纱张力不便直接测量，因此通过观察气圈形态来估计纺纱张力是十分可行的。
