The Large Hadron Collider witnesses the highest ever production cross-sectionof double parton scattering processes. The production of a Z-boson along withtwo jets from double parton scattering provides a unique opportunity to explorethe kinematics of double parton scattering processes and their dependence onthe scale of the second interaction. The experimental measurement of thisprocess is largely contaminated by Z + jets production from single partonscattering. In this paper, fragmentation properties of a jet are explored tocheck their sensitivity towards double parton scattering. The present study isperformed using simulated Z + jets events, produced with \textsc{madgraph} and\textsc{powheg} Monte-Carlo event generators, hadronized and parton showeredusing \textsc{pythia}8. The effect of different hadronization model on thediscrimination based on the fragmentation properties of a jet is alsoinvestigated by using events simulated with \textsc{herwig}++. It is observedthat discrimination based on the fragmentation properties of a jet cansignificantly suppress the background from single parton scattering, whichresults into 40--50\% gain in the contribution of double parton scattering.
