PTFE COATED FIBERGLASS THREAD 32 oz.

These nylon and polyester threads are manufactured from quality high tenacity,
heat resistant, continuous filament yarn. They are “Thermal Set” which creates
a low elongation soft thread, imparting many of the sewing characteristics of
natural fibers. The non-wicking finish helps to eliminate capillary seam damage.
Special waxes, silicones and oils are applied to lubricate the thread, reducing
needle heat while increasing sew ability and aiding in the application of constant
machine tension and good loop formation.

Non-lubricated thread is also available.
