Abstract

Procedure for the optical rinsing of fibrous polyacrylonitrile materials or of copolymers containing at least 85% polyacrylonitrile, with a 1,3-diaryl-Δ2-pyrazoline compound, characterized in that the fibrous material is impregnated with a lightening agent optical formula II **(See formula)** in which A means a lower, possibly branched, alcohol group, R1 means a lower alcohol group, R2 means lower alcohol groups, which together with the nitrogen atom can form a hydrogenated heterocyclic ring, X means a colorless anion and n means 1 or 2, It is brought to a moisture content of from about 5 to about 120% and heated for about 2 seconds to about 30 minutes to about 100 to about 150ºC.
