  • Polyorganosiloxane mixtures for treating fibre materials
    Patent number: 6706812
    Abstract: Polyorganosiloxane mixtures are obtainable by reacting linear polysiloxanes containing Si—H-bonds with linear dihydroxypolysiloxanes and amino-functional silanes. The reaction is carried out in such a way that the resultant product mixture still contains Si—H— bonds and leads to crosslinked structures. The polysiloxane mixtures obtained are useful for hydrophobicizing fiber materials, especially nonwovens.
    Type: Grant

  • Use of selected polydiorganosiloxanes in fabric softener compositions
    Patent number: 6358913
    Abstract: The invention relates to the use of fabric softener compositions comprising: (a) as active substance, a quaternary ammonium compound of formula (1), in which R is the aliphatic radical of tallow fatty acid, in particular a mono- or polyunsaturated aliphatic C17 radical; and (b) is a nitrogen-free polydiorganosiloxane having terminal silicon-bonded hydroxyl groups; for the treatment of textile fibre materials. The fabric softener compositions impart a soft handle to the treated textile and are readily biodegradable.

  • Aqueous dispersions for textile finishing
    Patent number: 6306958
    Abstract: Aqueous dispersions comprising as component A) a compound containing two or more blocked isocyanate groups in the molecule and as component B) a compound obtainable by reacting a diepoxy compound with a diamine or polyamine and subsequently reacting the resulting reaction product with an acid and possibly as component C) a dispersant are suited together with fluorine containing oligomers or polymers for the oil-, water- and soil-repellent finishing of fiber materials.
