DOCUMENT TYPE: Journal CA Section: 40 (Textiles) An accurate method is described for microdensitometric detn. of concn. fields of dyes in cross sections of synthetic fibers using a computer-controlled scanning microspectrophotometer. High accuracy of the data was achieved by correcting the optical distortion of the microspectrophotometer and by proper arrangement of the measuring sectors of cross sections of fibers. The method was adapted also for measurements of delustered fibers. The method is applicable in synthetic fiber manuf., as demonstrated by the example of polyester fibers dyed with disperse dyes. .
