It is evident that the spinning yarn composed of fibers is formed by the cohesion of fibers. Therefore, on an assumption the limited twist angle that measures the spinning power of the fiber is derived from the fomulas of lateral pressure, and it is shown as follows:
Where, μ is coeficient of friction between fibers, C is the thickness of fiber and Lr is the representative staple length. Futhermore, from the above equation, the experimental formula of spinning value can be derived, and the spinning values of cotton and viscose staple fiber can be calculated.
