We calculate the chiral odd quark distributions and the corresponding structure functions hT(x,Q2) and hL(x,Q2) within the Nambu-Jona-Lasinio chiral soliton model for the nucleon. The Q2 evolution of the twist-2 contributions is performed according to the standard GLAP formalism while the twist-3 piece h̄L,(x) is evolved according to the large NC scheme. We carry out a comparison between the chiral odd structure functions of the proton and the neutron. At the low model scale (Q20) we find that the leading twist effective quark distributions f(q)1(x,Q20), g(q)1(x,Q20) and h(q)T(x,Q20) satisfy Softer's inequality for both quark flavors q = u,d.
