In this paper we present the results of the polarization observations of 11 moustaches obtained with the Large Solar Vacuum Telescope at Baikal Astrophysical Observatory. The moustaches are situated near the regions with quick motion of plasma which reached velocities of 100 km/sec. On an average the moustache polarization is nearly 7% with direction of polarization oriented mainly to the disk center. Some peculiarities were discovered in the behavior of polarization parameters in Hα line center during the moustache life time.
