Abstract
In this study the following expreiments were carried out. Fullness (ω0=1-ε0) effect on withdrawal force Fs of a single fiber from bundle (eq. 7.1), effect of withdrawal speed V (eq. 7.2), and relative velocity of stick-slip motion v-<v> (eq. 7.3) were observed in the cases of various fiber bundles.On the basis of these experimental results, the expression of capacity C (eq. 7.9), transportability pressure u (eq. 7.10), resistance R (eq. 7.11), and self conductance L (eq. 7.12) for the fibre current I (eq. 7.5) in the drafting zone were defined by Boltzmann's average equation (7.8). From these treatments, following results were obtained:(1) Time dependency of fiber currents I in drafting zone is given by equation (7.14) and (7.17)(2) Spectrum density GI(ω) and auto-correlation coefficient ρ(τ) of sliver irregularity were given in (7.15)_??_(7.19).(3) When L=0, the equation of fibre motion under drafting is reduced to the heat conduction or diffusion equation (7.21) and if L_??_0, to the damping wave equation (7.23).
