  • Multiple step dyeing textile with concentrated dye systems
    Patent number: 8167958
    Abstract: The present invention relates to a process for dyeing sheetlike textile materials with a dye, which comprises a concentrated dye system being applied in a total amount of 1% to 25% by weight, based on the textile material, to the textile material in two or more sub-steps and the dye being fixed on the textile material after each and every sub-step.
    Type: Grant

  • Mediator systems based on mixed metal complexes, used for reducing dyes
    Patent number: 6790241
    Abstract: Mediator systems obtainable by mixing a salt of an electrochemically active complexing metal (M1) capable of forming a plurality of valence states with a hydroxyl-containing complexing agent, which may likewise be present as salt, and with a salt of an electrochemically inactive complexing metal (M2) in an alkaline aqueous medium, wherefor the molar ratio of metal ion M2 to metal ion M1 is from 0.8:1 to 2:1 are useful for reducing dyes and dyeing cellulosic textile material.

  • Process for extracting water from desizing liquors
    Patent number: 4333190
    Abstract: A process for desizing a fabric web comprising the steps of: first wetting the dry size-loaded fabric with the desizing liquor separated from a previous batch of fabric after desizing, so that the fabric, and the size adhering thereto, take up water from the desizing liquor by swelling and/or solvation, thereby increasing the concentration of the desizing liquor; separating the concentrated desizing liquor from the fabric; recycling the concentrated desizing liquor to a sizing operation; desizing the wetted fabric by a continuous fresh water wash; separating the desized fabric from the resulting desizing liquor; and recycling the desizing liquor to the first wetting step.
