  The transversity distribution can be measured at leading-twist in
single-particle inclusive DIS, where it appears in connection with chiral-odd
fragmentation functions. Among these functions, we focus on the time-reversal
odd ones. They occur in fragmentation to unpolarized hadrons or polarized
spin-one hadrons. Using a simple model, we show how these functions can be
non-vanishing and we discuss the asymmetries where they can be measured
together with the transversity distribution.
