Abstract: Luminescence of polyester fibers colored by different luminophores using craising mechanism was investigated. Arrangement for interrupted modification of fibers by luminescent colorants was designed. Optimal thickness of fiber bundle ($90\div100$ fibers) subjected to modification was estimated. Effective fiber coloration takes place when the drawing out degree is between $2$ and $3$. It was shown that fibers modified by Oksasin and Rodamin are characterized by the highest intensity of luminescence in UV radiation.

Keywords: polyester fibers, craising, modification, luminescent colorants, luminescence spectrum.
