Abstract
A method is disclosed whereby the amount of a lubricant composition such as a spin finish, coning oil, etc. applied to a textile strand may be accurately determined in a matter of seconds or minutes. The method involves applying to a running length textile strand a lubricant composition containing a tracer, winding the lubricated strand into a package, and subjecting the package to nondestructive analysis with an X-ray spectrochemical analyzer to measure the amount of tracer present in the package and to thereby obtain a measurement of the relative amount of lubricant applied to the strand.
Claims16
A nondestructive testing method for quickly measuring the amount of a coating applied to a strand, said method employing a radiation analysis instrument having a predetermined field and being adapted for quantitatively measuring a tracer, said method comprising applying to a running length strand a coating composition containing a tracer, winding the coated strand into a package of infinite mass relative to the field of the analysis instrument, and subjecting the package to analysis by the instrument to obtain a reading of the amount of tracer within the field of the instrument, which reading provides a relative indication of the amount of coating applied to the individual strand.
A nondestructive testing method for quickly measuring the amount of a lubricant coating applied to a textile strand and wherein the coating contains a tracer quantitatively measurable by an X-ray spectrochemical analyzer having a predetermined field, said method comprising preparing a sample of the coated textile strand which is of infinite mass relative to the analyzer, positioning the sample within the field of the analyzer, and obtaining a reading from the analyzer of the amount of tracer on the portion of the sample within the field thereof to thereby obtain a relative indication of the amount of coating applied to the individual strand.
A nondestructive testing method for quickly measuring the amount of lubricant applied to a textile strand said method employing an X-ray spectrochemical analyzer having a probe with a predetermined field and being adapted for measuring the amount of a predetermined element located within the field of the probe, said method comprising applying to a running length textile strand a lubricant composition containing a predetermined tracer element, winding the lubricated strand into a package of a width and thickness sufficient to fill the field of the probe, positioning the package in close proximity to the probe, and measuring with the analyzer the amount of the predetermined tracer element present in the portion of the package within the field of the probe to thereby obtain a reading proportional to the amount of lubricant applied to the individual strand.
