摘要 |
An anhydrous preparation for finishing sewing yarn and sewing thread is disclosed. The preparation essentially consists of 65 to 99% by weight of a dimethylpolysiloxane with a viscosity of 50 to 10,000 mm2/S-1 at 25 DEG C. and a hydroxyl content of 0.3 to 1.5% by weight and 1 to 30% by weight of a fatty acid or a fatty amine with, on the average, 8 to 18 carbon atoms and, optionally, 0 to 5% by weight of conventional additives. The preparation are easy to prepare and have an unlimited shelf life and a constant viscosity even over a prolonged period of storage. The preparation confer low thread tension, decreased yarn breakage and improved stick-slip properties on the sewing yarn and thread.
