We construct the Drinfeld twists (factorizing $F$-matrices) for thesupersymmetric t-J model. Working in the basis provided by the $F$-matrix (i.e.the so-called $F$-basis), we obtain completely symmetric representations of themonodromy matrix and the pseudo-particle creation operators of the model. Theseenable us to resolve the hierarchy of the nested Bethe vectors for the$gl(2|1)$ invariant t-J model.Comment: 23 pages, no figure, Latex file, minor misprints are correcte
