Abstract: Disclosed is a method for producing a modified animal fiber, the method includes step 1 (31, 32) of pre-oxidizing a cystine bond (—S—S— bond) present in an epidermal cell of an animal fiber to bring the cystine bond into a low oxidation state, step 2 (33) of oxidizing with ozone the pre-oxidized —S—S— bond to bring the —S—S— bond into at least one high oxidation state selected from di-, tri-, and tetra-oxidation states, and step 3 (34) of reductively cleaving the —S—S— bond in a high oxidation state. The method imparts shrink resistance and pilling resistance to an animal fiber. In the step 2 (33) ozone is microdispersed in an aqueous solution comprising an anionic surfactant having a C8-24 alkyl group, and the animal fiber is contacted with the ozone.

Abstract: Described are polysiloxane compositions that are obtainable in 2 steps. The first step comprises reacting a linear organopolysiloxane which contains Si—H bonds with a compound that has a terminal C═C double bond and a polyoxyalkylene chain. This reaction is carried out in such a way that Si—H bonds are still present in the resultant product. The second step comprises adding a base or water and an acid to the resultant product. The hydrophilic properties of the resultant polysiloxane compositions can be influenced in a specific manner. The compositions are useful for treating fiber materials, especially textile fabrics. The effects obtained are notable for good durability. Further groups may be incorporated into the polysiloxanes to open up further applications.
