  We present a theoretical analysis of the recent experimental results of
Thomas et al on transport properties of spin polarized quantum wires. We
suggest an explanation of the observed deviations of the conductance from the
universal value $G=2e^2/h$ per channel in the wire. We argue that the new quasi
plateau observed for the conductance at the value $G=1.4e^2/h$ is a result of
the proximity between the spin polarized phase and the metallic one. The
enhancement of the conductance from the value $G=e^2/h$ to $G=1.4e^2/h$ is due
to the hybridization of the electronic state at $K_F^{\downarrow}\approx 0$
with the chiral states at $K_F^{\uparrow}$ and $-K_F^{\uparrow}$.
