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。
