It’s not only DMC who produce Z-twist thread for sewing machines.  Just
about all threads intended for use with a domestic sewing machine -
embroidery, quilting, sewing seams, overlocking/serging - will be Z-twist
(left)  because of the way sewing machines work, and I think that’s true for
industrial machines too.   In almost all machines the needle goes into the
fabric taking a loop of thread with it and the shuttle hook, or whatever, that
forms the stitch with a second thread (bobbin or looper) enters the needle
thread loop from the right.   That tends to tighten a Z-twist or loosen an
S-twist.
