Numerical predictions are given for the spin transfers of the produced $\\Lambda$, when the target nucleon is polarized either longitudinally or transversely, and with the nucleon and $\\Lambda$ quark distributions evaluated both in an SU(6) quark-spectator-diquark model and in a perturbative QCD (pQCD) based model.
