Abstract
Materials for substantively preparing yarns or plied yarns, especially sewing threads and preferably those of polyester, in the form of an oil/water dispersion are disclosed. The materials contain 5 to 80 weight percent of silicone oil of a viscosity of 500 to 50,000 mm.sup.2 /sec at 25.degree. C., 10 to 80 weight percent of wax with a melting point not less than 40.degree. C., 1 to 10 weight percent of fatty acids with 6 to 22 carbon atoms, 0.4 to 12 weight percent of cationic imidazolinium salts and 0 to 10 weight percent of ethoxylated fatty amines, dissolved or dispersed in water, the sum of the components having to add up to 100 weight percent. The production of this preparation is also disclosed. The inventive preparation materials have a good and uniform substantivity and bring about uniform reduction in friction over a long length of yarn and for different speeds of the running thread. They ensure little abrasion in the further processing of the yarns, especially during sewing, and at the same time, provide a high measure of antistatic effect. The breaking strength of the yarns or plied yarns is not significantly decreased.
