Abstract: Disclosed is an oxidizing system comprising a macrocyclic metal complex, an oxidizing agent and an oxidation-enhancing compound. This oxidizing system is useful under a wide variety of reaction conditions for oxidizing oxidizable substances by contacting the oxidizable substance with the specific oxidizing system. An example of a possible use is in a process for removing excess, unfixed dye from textile materials after a dyeing.

Abstract: The use of an oxidizing system comprising a macrocyclic metal complex and an oxidizing agent removes excess, unfixed dye from dyed, textile materials after dyeing without the actual dyeing of the textile material being attacked. The oxidizing system is preferably used in at least one of the post-dyeing rinse steps.

Abstract: A process is provided for preparing specific polycarboxylic acids by oxidative cleavage of double-bond compounds with hydrogen peroxide or hydrogen peroxide donors. The polycarboxylic acids thus obtained are notable for excellent acid stability, and consequently ease of handling in aqueous solution and are useful for treating cellulosic fibers or textile or paper materials produced therefrom.

Abstract: A pressure roller for textile machines, in particular for a texturing machine, is provided. A covering (3) is preferably arranged over an intermediate sheath (4) on a support sheath (S). The support sheath (5) is rotatably supported via a deep groove ball bearing (1) on a carrying axle (2). For cost-effective manufacturing of a pressure roller, a standardized deep groove ball bearing (1) that has at least an outer bearing race (6, 7) and balls (9) that roll on the ball grooves (10, 11) of the bearing race (6, 7) is proposed, the outer bearing race (6) of which carries the support sheath. The standardized deep groove ball bearing amounts to at maximum 80 percent of the axial extension of the support sheath (5).

Abstract: The invention relates to substrates bearing visible information that is secure against unauthorized copying obtained by applying information in the form of combinations of at least one emitting colorant and at least one reflecting colorant that are selected to exhibit similar or identical hues when viewed, with no cognizance being taken of fluorescence, and are applied in such a manner that their color fields touch, wherein the color loci of the two colorants correspond to one of the trichromatic colors yellow, magenta, or cyan and the reflecting colorant is an organic or inorganic pigment.
