IF QI模型机理性强、自变量少、形式简单直观，而且与单纱强力、纺纱均匀指数呈正相关。

The model of IFQI has many advances, such as explicit mechanism, few independent variables, simple and intuitive, having positive relative with yarn strength and spinning consistence index and so on.

近几年又提出了新的表示成纱品质质量的指标，如纺纱均匀性指数、原棉综合指数等。

Recently, new indexes of spinning yarn quality have been suggested, for example, spinning Consistence index and Integrated Cotton index.
