Abstract：Based on the experiments of spinning yarn, and using the principal component analysis to the detecting data of cotton fiber qualities, the results showed that as follows: ⑴ The cotton fiber qualities are crucial factors to spinning strength. Though a kind of raw cotton strength change with technology, but the strength trends are the same under different technology comparing to other raw cottons. The higher the cotton fiber qualities are, the higher their spinning strengths are under any technology and counts; ⑵ The spinning strength has something to do with spinning counts and spinning technology ; ⑶ The pivotal indexes expressing the cotton fiber quality are fiber length, strength,microafis and uniformity .The model of single spinning strength of combed yarn and the model of singe spinning strength of carded yarn are established as: CSCO=（40-k₁×C）×k₂××Str×Unf，CSCA=CSCO×（1+CAWD），CAWD=W/66.67. The model have many advances, such as explicit mechanism, few independent variables, simple and intuitionist, good expected validity, easy application and dissemination and non liner model.
