Paper Abstract

Oxidative pretreatment for printing of wool fabrics is necessary to degenerate the fiber surface in order to improve dyestuff absorption. Industrially applied chlorination causes environmental problems. A new method based on catalyzed hydrogen peroxide was developed. FT-IR- investigations in different techniques (KBr-pellet, ATR, diamond optical anvil cell) gave information about the degree of oxidation of the wool fibers, in particular the fiber surface, and the dyestuff absorption.
