  • Patent number: 4427815
    Abstract: Fiber-treating compositions are disclosed which have, as their effective components, two organopolysiloxanes. One of the organopolysiloxanes contain carboxylic-substituted hydrocarbon groups. The other organopolysiloxane contains polyoxyalkylene-substituted hydrocarbon groups and either amine-substituted hydrocarbon groups or epoxy-substituted hydrocarbon groups. These compositions, when applied to a fiber material and heated, react to provide a durable silicone treatment for the material.

  • Patent number: 4417024
    Abstract: Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fiber. These compositions comprise a siloxane component bearing fluorinated hydrocarbon radicals, unsubstituted hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation condensation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radical of an optionally added hydroxyl-endblocked organopolysiloxanes.

  • Patent number: 4399247
    Abstract: Aqueous organopolysiloxane compositions are disclosed which are useful for durably treating substrates such as fibers, textiles and sheet-form materials. The aqueous organopolysiloxane compositions further contain an acid to adjust the pH of the composition to a non-basic value, an organic ester of titanic, zirconic or germanic acid and a surfactant to render the composition homogeneous. The organopolysiloxane contains monovalent hydrocarbon groups, aminohydrocarbon groups, hydroxy- or ether hydrocarbon groups and, optionally silicon-bonded hydroxyl and/or alkoxy groups.

  • Patent number: 4366001
    Abstract: Fiber-treating compositions are disclosed which contain two types of organofunctional polysiloxanes, one bearing amino-functional organic radicals or carboxy-functional organic radicals or epoxy-functional radicals and the other bearing another type of organofunctional radicals selected from the same group. In addition, at least one of the organofunctional polysiloxanes bears one or more polyoxyalkylene radicals.These compositions are useful for durably treating fibers to provide several benefits such as antistatic character, moisture/perspiration absorbability, stain resistance, pliability, smoothness, crease resistance and compression recovery.

  • Patent number: 4355149
    Abstract: Fiber-treating compositions are described which durably provide water repellency and oil repellency for the treated fibers. These compositions comprise a cyclic siloxane bearing fluorinated hydrocarbon radicals and silicon-hydride atoms, and a dehydrogenation catalyst. Curing of the compositions occurs by a dehydrogenation condensation reaction between the silicon-hydride atoms and/or between the silicon-hydride atoms and the hydroxyl radicals of an optionally added hydroxyl-endblocked organopolysiloxane.
