A lubricating composition to improve the sliding properties of organic fibers comprising an organosilicon compound having at least one OSiR2 unit and a compound selected from the group consisting of O=P[(OCHR1CHR1)nOR2]3, NR42+x- and mixtures thereof, where R is a hydrocarbon radical or a substituted hydrocarbon radical, R1 represents hydrogen or the methyl group, with the proviso that in each -OCHR1CHR1 unit at least one R1 must be hydrogen, R2 represents hydrogen or a monovalent hydrocarbon radical having from 1 to 20 carbon atoms, with the proviso that in each compound of the formula NR42+x-at least two of the R2 radicals must represent hydrocarbon radicals, n is either O or an integer having a value of from 1 to 15, with the proviso that when R2 is hydrogen in each of the phosphorus compounds, n must be at least 1 and that at least one -OCHR1CHR1 unit must be present in each of the phosphorus compounds and x-represents an anion of an organic or inorganic acid. These compounds not only improve the sliding properties of organic fibers, but also impart antielectrostatic properties to the treated fibers. |
