SAUNDERS THREAD SPECIFICATIONS
*Actual yield depends on type and % of lubricant, if any.
ST - POLYPROPYLENE soft is finished with lubrications that are specially designed for the sewing operations involved. These lubricants are formulated from carefully selected combinations of waxes, silicones, and oils. They provide consistent machine tensions and loop formation and in addition, afford protection from needle heat to insure good sewability.
ST - POLYPROPYLENE is also available with silicone free lubricants as well as no finish (dry) when required for use in certain filter sewing.
