An expression of partial-wave expansion three-baryon interactions in chiral effective field theory is presented. The derivation follows the method by Hebeler et al. [Phys. Rev. C 91, 044001 (2015)], but final more general. That is, a systematic treatment higher-rank spin-momentum structure interaction becomes possible. Using derived formula, $\mathrm{\ensuremath{\Lambda}}$-deuteron folding potential evaluated. This information valuable for inferring possible contribution $\mathrm{\ensuremath{\Lambda}}NN$ forces to hypertriton as basis further studies sophisticated Faddeev calculations. A microscopic understanding together with two-body $\mathrm{\ensuremath{\Lambda}}N$ essential description hypernuclei and neutron-star matter.
