A study was conducted to demonstrate that charge fractionalization does not occur in the low temperature 2kF spin-Peierls (SP) phase of the interacting 1D 1/4-filled band. It was shown that the charge ordering associated with the SP tetramerization causes a "re-integerization" of the fractionally charged defects that occur within the 4kF dimerized phase.
