High sew ing security and good sew ability are achieved w iththe
follow ing core threads:
–
Tw o-ply polyesterendless polyestercore-spun
(e .g.EpicPoly-P oly,R asantx,S aba C ,...)
–
Tw o-ply polyesterendless cotton core-spun
(e .g.Frikka,Koban,R asant,...)
Ifthese threads are notavailable,the polyesterfibre orcotton threads
listed inthe table can also be sew n.
Often two-plycorethreads are offered by the thread m anufacturers
withthe sam e designation as three-ply polyesterfibre threads
(3cyl.-spun).This causes uncertaintywith regard totwisting and thread
thickness.
W hen in doubt,unravelthe thread and check w hetheritistwisted 2-or
3-ply.
The labelno.120 on the thread reelofa core thread corresponds e.g.
tothe thread size N m 80/2(seetablevalues in brackets).
In case ofm onofilam entthreads you can use needlethreads and hook
threads ofthe sam e thickness.The bestresults are achieved w ithsoft
and elasticthreads (software)ofthe thread thickness 130 D enier.
