Masterbatch method for economically and efficiently producing soap dispersions in textile fluids for synthetic fiber treatment

摘要

A method for preparing dispersions of solid salts of fatty acids in low polarity liquids where a concentrated mixture of at least 50 percent of the solid salts of fatty acids in a low polarity liquid is subjected to high shearing forces, until the average particle size of the solid salts of fatty acids is less than 3 micron. The dispersion may then be diluted with the low polarity liquid to a lower concentration. The solid salt of the fatty acid is most preferably magnesium stearate, and the low polarity liquid is preferably a polydimethylsiloxane fluid having a viscosity of less than 100 centistoke (mm<2>/s).
