  1. Untersuchungen zur Sorption von Innenraum-Luftschadstoffen durch Wolle

    This dissertation concerns itself with the sorption behaviour of wool concerning some important interior air pollutants. Apart from the intake of toluol as an organic substance frequently provable in high concentrations in the interior air, the sorption and possible reactivity of several aldehydes …

  2. Zur Einwirkung von Ozon auf Wolle und Aminosäuren

    Solid histidine shows no reaction during ozonation. In contrast, the ozonation of aqueous solutions of histidine reveals quick and effective oxidation. Ozone consumption during histidine treatment is passing two phases. Depending on the duration of the ozone treatment the consumption rate is …

  3. Oxidationshaarfarbstoffe als alternative Farbstoffe für das Färben von Wolle

    Investigations on selected oxidation hair dyes - which are normally applied in the form of gels and pastes - have shown that it is possible to use these dyes on wool in commercial wool dyeing procedure. The precursors are applied at low low temperatures (e.g. 60oC) and short treatment times (20 …

  4. Untersuchungen zur Modifizierung der Zellmembranlipide von Wolle durch industrielle Ausrüstungsprozesse

    The aim of the present work was to examine, if wet processing of wool e.g. chlorination, chlorine/Hercosett treatment and reactive wool dyeing, generates modified lipids, which might contribute to skin irritation. Therefore, the composition of solvent extractable cell membrane lipids of …

  5. Modifizierung von Wolle durch Enzyme mit dem Ziel der Griffverbesserung und Filzfreiausrüstung

    This study investigates the effect of different enzymes on wool top. Wool top was incubated with proteases SP 655, SP 656, SP 490 as well as with lipase SP 398. The changes in wool morphology that occurred as a result of the enzyme treatment were shown by means of scanning electron microscopy and …
