  • Patent number: 10697113
    Abstract: The aim is to reduce the wrinkling tendency of a cotton textile or otherwise cellulosic textile. This was achieved by bringing the textile into contact with an amino-group-containing polymer having carboxylic-acid-group-bearing substituents and optionally subsequently ironing the textile.
    Type: Grant
    Filed: May 8, 2017
    Date of Patent: June 30, 2020
    Assignee: Henkel AG & Co. KGaA

  • Publication number: 20100267300
    Abstract: The invention relates to a process for the preparation of reactive cyclodextrins, in which process the cyclodextrins CD are reacted with a bifunctional alkyl compound X—(CH2)n—Y, wherein X is a group which reacts with CD, n is an integer from 2 to 20 and Y is a group which reacts with a group Z or is a group-Reactive which is capable of reaction with cellulosic or proteinic materials and, optionally, in a further step, insofar as Y is a group which reacts with a group Z, the resulting product is reacted with a reactive anchor compound Z-Reactive to form the reactive cyclodextrin, and also to reactive cyclodextrins prepared in accordance therewith, to materials dressed therewith and to the use thereof.
